5.1 Connections
5.1.1 Preparation
Normal testing conditions
• Turn on the vehicle power supply.
• Vehicle battery voltage range should be 9-14V and working voltage
of Maximus 3.0 is 5V.
• Throttle should be closed at its close position.
5.1.2 DLC Location
1. For Passenger Cars,
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic code readers
interface with the vehicle’s on-board computer. The DLC is usually
located 12 inches from the center of the instrument panel (dash),
under or around the driver’s side for most vehicles. If Data Link
Connector is not located under dashboard, a label should be there
telling location. For some Asian and European vehicles, the DLC
is located behind the ashtray and the ashtray must be removed
to access the connector. If the DLC cannot be found, refer to the
vehicle’s service manual for the location.
Fig. 5-1
2. For Commercial Vehicles,
The DLC is generally located in driver’s cab.
5.1.3 Vehicle Connection (For Passenger Vehicle Version)
The method used to connect the VCI device to a vehicle’s DLC
depends on the vehicle’s conguration as follows:
• A vehicle equipped with an OBD II management system supplies
both communication and 12V power through a standardized DLC.
• A vehicle not equipped with an OBD II management system
supplies communication through a DLC connection, and in some
cases supplies 12V power through the cigarette lighter receptacle
or a connection to the vehicle battery.
Follow the steps mentioned below to connect OBD II vehicle:
1. Locate vehicle’s DLC socket.
2. Plug the VCI device into the vehicle’s DLC socket (It is suggested
to use the OBD II extension cable to connect the VCI device and
DLC socket.).
3. Choose one of the two ways to obtain power from:
A. Power adaptor: Connect one end of the included power adaptor
to Power interface of Maximus 3.0 tablet, and the other end to
AC outlet.
B. Internal battery pack: For details on how to recharge Maximus
3.0, see “Chapter 3.1 Charging Maximus 3.0”.
For non-OBDII vehicle, proceed as follows:
1. Locate vehicle’s DLC socket.
2. Select the corresponding non-16pin dongle.
3. Plug the non-16pin end of the dongle into the DLC socket, then
connect the other end to the OBD I adaptor, and then tighten the
captive screws.
4. Connect the other end of the adaptor to the included VCI device.

Number) information of the currently identied vehicle. Once the VIN
is successfully identified, the system will retrieve it from the remote
server and then guide you to vehicle information page without the
necessity of step-by-step manual menu selection (Early model may
need manual selection).
The vehicle information page lists all historical diagnostic records of
the vehicle, which lets the technician have a total command of the
vehicle faults. In addition, a quick dial to local diagnosis and diagnostic
function are also available on this page for reducing the roundabout
time and increasing productivity.

E. Actuation Test
This option is used to access vehicle-specific subsystem and
component tests. Available test vary by vehicle manufacturer, year,
and model. During the actuation test, the Maximus 3.0 handset
outputs commands to the ECU in order to drive the actuators, and
then determines the integrity of the system or parts by reading the
ECU data, or by monitoring the operation of the actuators, such as
switching a injector between two operating states.
In Fig. 5-25, tap “Actuation Test”, the system will display as follows:

cycle.
2. After changing engine oil or electric appliances that monitor oil life,
you need to reset the service lamp.
5.4.2 Electronic Parking Brake Reset
1. If the brake pad wears the brake pad sense line, the brake pad
sense line sends a signal sense line to the on-board computer to
replace the brake pad. After replacing the brake pad, you must
reset the brake pad. Otherwise, the car alarms.
2. Reset must be performed in the following cases:
a) The brake pad and brake pad wear sensor are replaced.
b) The brake pad indicator lamp is on.
c) The brake pad sensor circuit is short, which is recovered.
d) The servo motor is replaced.
5.4.3 Steering Angle Calibration
To reset the steering angle, rst nd the relative zero point position for
the car to drive in straight line. Taking this position as reference, the
ECU can calculate the accurate angle for left and right steering.
After replacing the steering angle position sensor, replacing steering
mechanical parts (such as steering gearbox, steering column, end tie
rod, steering knuckle), performing four-wheel alignment, or recovering
car body, you must reset the steering angle.
5.4.4 ABS Bleeding
This function allows you to perform various bi-directional tests to check
the operating conditions of Anti-lock Braking System (ABS).
1. When the ABS contains air, the ABS bleeding function must
be performed to bleed the brake system to restore ABS brake
sensitivity.
2. If the ABS computer, ABS pump, brake master cylinder, brake
cylinder, brake line, or brake fluid is replaced, the ABS bleeding
function must be performed to bleed the ABS.
5.4.5 Tire Pressure Monitor System Reset
This function allows you to quickly look up the tire sensor IDs from the
vehicle’s ECU, as well as to perform TPMS replacement and sensor
test.
1. After the tire pressure MIL turns on and maintenance is performed,
the tire pressure resetting function must be performed to reset tire
pressure and turn off the tire pressure MIL.
2. Tire pressure resetting must be performed after maintenance is
performed in the following cases: tire pressure is too low, tire leaks,
tire pressure monitoring device is replaced or installed, tire is
replaced, tire pressure sensor is damaged, and tire is replaced for
the car with tire pressure monitoring function.
5.4.6 Gear Learning
The crankshaft position sensor learns crankshaft tooth machining
tolerance and saves to the computer to more accurately diagnose
engine misres. If tooth learning is not performed for a car equipped
with Delphi engine, the MIL turns on after the engine is started. The
diagnostic device detects the DTC P1336 ‘tooth not learned’. In this
case, you must use the diagnostic device to perform tooth learning for
the car. After tooth learning is successful, the MIL turns off.
After the engine ECU, crankshaft position sensor, or crankshaft
ywheel is replaced, or the DTC ‘tooth not learned’ is present, tooth
learning must be performed.
5.4.7 IMMO Service
An immobilizer is an anti-theft mechanism that prevents a vehicle’s
34
Maximus 3.0 User's Manual
engine from starting unless the correct ignition key or other device
is present. Most new vehicles have an immobilizer as standard
equipment. An important advantage of this system is that it doesn’t
require the car owner to activate it since it operates automatically. An
immobilizer is considered as providing much more effective anti-theft
protection than an audible alarm alone.
As an anti-theft device, an immobilizer disables one of the systems
needed to start a car’s engine, usually the ignition or the fuel supply.
This is accomplished by radio frequency identification between a
transponder in the ignition key and a device called a radio frequency
reader in the steering column. When the key is placed in the ignition,
the transponder sends a signal with a unique identication code to the
reader, which relays it to a receiver in the vehicle’s computer control
module. If the code is correct, the computer allows the fuel supply and
ignition systems to operate and start the car. If the code is incorrect or
absent, the computer disables the system, and the car will be unable
to start until the correct key is placed in the ignition.
To prevent the car being used by unauthorized keys, the anti-theft key
matching function must be performed so that the immobilizer control
system on the car identifies and authorizes remote control keys to
normally use the car.
When the ignition switch key, ignition switch, combined instrument
panel, ECU, BCM, or remote control battery is replaced, anti-theft key
matching must be performed.
5.4.8 Injector Coding
Write injector actual code or rewrite code in the ECU to the injector
code of the corresponding cylinder so as to more accurately control or
correct cylinder injection quantity.
After the ECU or injector is replaced, injector code of each cylinder
must be conrmed or re-coded so that the cylinder can better identify
injectors to accurately control fuel injection.
5.4.9 Battery Maintenance System Reset
This function enables you to perform a resetting operation on the
monitoring unit of vehicle battery, in which the original low battery fault
information will be cleared and battery matching will be done.
Battery matching must be performed in the following cases:
a) Main battery is replaced. Battery matching must be performed to
clear original low battery information and prevent the related control
module from detecting false information. If the related control
module detects false information, it will invalidate some electric
auxiliary functions, such as automatic start & stop function, sunroof
without one-key trigger function, power window without automatic
function.
b) Battery monitoring sensor. Battery matching is performed to re-
match the control module and motoring sensor to detect battery
power usage more accurately, which can avoid an error message
displaying on the instrument panel.
5.4.10 Diesel Particulate Filter (DPF) Regeneration
DPF regeneration is used to clear PM (Particulate Matter) from the
DPF filter through continuous combustion oxidation mode (such as
high temperature heating combustion, fuel additive or catalyst reduce
PM ignition combustion) to stabilize the lter performance.
DPF regeneration may be performed in the following cases:
a) The exhaust back pressure sensor is replaced.
b) The PM trap is removed or replaced.
c) The fuel additive nozzle is removed or replaced.
d) The catalytic oxidizer is removed or replaced.
e) The DPF regeneration MIL is on and maintenance is performed.
f) The DPF regeneration control module is replaced.

5.4.11 Electronic Throttle Position Reset
This function enables you to make initial settings to throttle actuators
and returns the “learned” values stored on ECU to the default state.
Doing so can accurately control the actions of regulating throttle (or
idle engine) to adjust the amount of air intake.
5.4.12 Gearbox Matching
1. This function can complete the gearbox self-learning to improve
gear shifting quality.
2. When the gearbox is disassembled or repaired (after some of
the car battery is powered off), it will lead to shift delay or impact
problem. In this case, this function needs to be done so that the
gearbox can automatically compensate according to the driving
conditions so as to achieve more comfortable and better shift
quality.
5.4.13 AFS (Adaptive Front-lighting System) Reset
This feature is used to initialize the adaptive headlamp system.
According to the ambient light intensity, the adaptive headlamp system
may decide whether to automatically turn on the headlamps, and
timely adjust the headlamp lighting angle while monitoring the vehicle
speed and body posture.
5.4.14 Sunroof Initialization
This function can set the sunroof lock off, closed when it rains, sliding /
tilting sunroof memory function, temperature threshold outside the car
etc.
5.4.15 Suspension Calibration
1. This function can adjust the height of the body.
2. When replacing the body height sensor in the air suspension
system, or control module or when the vehicle level is incorrect,
you need to perform this function to adjust the body height sensor
for level calibration.
5.5 Diagnostic History (Previous Session)

5.6 I/M Readiness
An important part of a vehicle’s OBD II system is the Readiness
Monitors, which are indicators used to nd out if all of the emissions
components have been evaluated by the OBD II system. They are
running periodic tests on specic systems and components to ensure
that they are performing within allowable limits.
Currently, there are eleven OBD II Readiness Monitors (or I/M
Monitors) defined by the U.S. Environmental Protection Agency
(EPA). Not all monitors are supported in every vehicles and the exact
number of monitors in any vehicle depends on the motor vehicle
manufacturer’s emissions control strategy.
Continuous Monitors -- Some of the vehicle components or systems
are continuously tested by the vehicle’s OBD II system, while others
are tested only under specific vehicle operating conditions. The
continuously monitored components listed below are always ready:
1. Misre
2. Fuel System
3. Comprehensive Components (CCM)
Once the vehicle is running, the OBD II system is continuously
checking the above components, monitoring key engine sensors,
watching for engine misre, and monitoring fuel demands.
Non-Continuous Monitors -- Unlike the continuous monitors, many
emissions and engine system components require the vehicle to be
operated under specic conditions before the monitor is ready. These
monitors are termed non-continuous monitors and are listed below:
1) EGR System
2) O2 Sensors
3) Catalyst
4) Evaporative System
5) O2 Sensor Heater
6) Secondary air Injection
7) Heated Catalyst
8) A/C system
I/M refers to Inspection and Maintenance that is legislated by the
Government to meet federal clean-air standards. I/M Readiness
indicates whether or not the various emissions-related systems on
the vehicle are operating properly and are ready for Inspection and
Maintenance testing.
The purpose of the I/M Readiness Monitor Status is to indicate which
of the vehicle’s Monitors have run and completed their diagnosis
and testing, and which ones have not yet run and completed testing
and diagnosis of their designated sections of the vehicle’s emissions
system.
The I/M Readiness Monitor Status function also can be used (after
repair of a fault has been performed) to confirm that the repair has
been performed correctly, and/or to check for Monitor Run Status.
Tap [I/M Readiness] on the Diagnostics main menu screen to start
checking. After checking all I/M readiness status, the screen will output
the result.
*Note: means not available on this vehicle, means incomplete or
not ready, means Completed or Monitor Ok.

7.1.3 Sensor Simulation
7.1.3.1 Connections
1. Firstly, power on the Maximus 3.0 handset.
1. Connect the B-shaped terminal of data cable to the B-shaped port
of the Sensorbox, and the other end to the Data transmission port
of the Maximus 3.0 handset.
2. Plug one end of the sensor test cable (black) into the “COM”
interface of the sensorbox, then connect the other end to the test
probe or electronic control converting cable.
3. Connect one end of the sensor test cable (red) into the “VΩHz”
interface of the sensorbox, and then connect the other end to the
test probe or electronic control converting cable.
*Note: Choose corresponding cables and test probes according to dierent
terminals.
7.1.3.2 Simulation test
Simulation test enables users to exactly judge if the sensor is good or
not to avoid replacing components blindly. For example, the trouble
code indicates the fault is in water temperature sensor itself. But we
need to confirm whether the fault results from water temperature
sensor or the connections between ECU and sensors, or ECU itself.
In this case, we can make full use of simulation test to input the signal
of simulating water temperature sensor, instead of water temperature
sensor, to the microcomputer. If the engine works better and the fault
vanishes, the fault is in the water temperature sensor. If the fault
still occurs, input the signal to the corresponding terminals of ECU.
Consequently, if the fault disappears, the fault lies in the connection
between water temperature sensor and ECU, otherwise, the fault
exists in ECU.
After all connections are properly made, power on your Maximus 3.0,
launch Maximus 3.0 application and enter the function menu interface,
then tap “Sensor” to enter the test selection screen.

4. Hand-painted waveform simulation
This option offers great convenience for users to simulate special
waveform or fault wave. Users only draw the shape of waveform which
needs to be simulated in central drawing area, and then configure
some parameters on the top, namely high level, low level, and cycle
of waveform, then tap , Maximus 3.0 will output a waveform as
desired.
Warning: Just draw a complete periodic waveform (when it is outpued,
the system will regard the waveform in the drawing area as a periodic one).
Users should draw as large as wave in drawing zone so that the system can
sample more points to reduce tolerance. While drawing, just pay aenon
to the shape of waveform, high level, low level and period can be ignored,
which can be set in the Congure opon.

7.1.3.3 Precautions on checking vehicle sensor
• Hold the connector when plugging or unplugging it. Do not pull the
cable for unplugging.
• At rst check the fuse, fusible line and terminals. Then check others
after eliminating these faults.
• When measuring voltage, the ignition switch should be on and the
battery voltage should not be less than 11V.
• When measuring voltage, please shake the lead lightly in the
vertical and horizontal direction for more precision.
• When checking whether there is open in the line, disconnect the
CEU and the relevant sensor at rst, then measure the resistance
among the ports of sensor in order to determine whether open-
circuit / contact fault exists or not.
• When checking if there is a short in the line, please disconnect the
CEU and the relevant sensor, then measure the resistance value of
the ports between the connected port and the vehicle body. If the
resistance value is more than 1MΩ, no fault occurs.
• Before disassembling the engine electrical control system cable,
cut off the power supply, that is, turn the ignition switch OFF and
disconnect the cables on the battery poles.
• Contact the test probe and the two terminals/ the two leads to be
measured when measuring the voltage between the two terminals
or the two leads.
• Contact the red test probe to the terminal/ the cable to be
measured, and the black probe to the ground when measuring
voltage of one terminal/ one cable.
• When checking the continuity of the terminals, contacts and leads,
the method for measuring their resistances can be used.
• Check the faults in the terminals of the CEU to sensors, relays, etc.
• There are two test probes in the testing wire. The black one is the
common signal terminal (signal GND); the red one is the input
terminal for voltage, resistance, and frequency test and output
terminal for simulation voltage, simulation frequency and oxygen
sensor. Please choose the correct probes to match the different
terminals.

Independent testing:
Unplug the wire connector of coolant temperature sensor, then remove
the sensor from the engine; place the sensor into a breaker with water
and heat the water, then use the “Resistance measurement” to test
the Resistance between two terminals of coolant temperature sensor
at different water temperature. Compared the measured value with the
standard value, if the Resistance is not compliant with the standard,
then the coolant temperature sensor shall be replaced.
(2) Output signal voltage testing for coolant temperature sensor
After installing the coolant temperature sensor, plug the wire connector
of sensor, and then switch ignition ON, test the output signal voltage
between the two terminals of wire connector. The tested voltage shall
be in inverse proportional with the coolant temperature. When the
harness of coolant temperature sensor is disconnected, the voltage
shall be about 5V if the ignition switch is ON.
7.2 Batterybox (Optional)
7.2.1 Product Summary
Maximus 3.0 provides an optional function of automotive battery
test, which adopts the latest state-of-the-art conductance testing
technology in the world and can test vehicle’s battery status. Two
testing environments (Inside the Vehicle and Outside the Vehicle)
are available and applicable to battery test. In addition to battery test,
charging system and actuation system test can be done while Inside
the Vehicle is selected.
It supports various battery standards and specifications, including
CCA, DIN, IEC, EN, JIS, SAE and GB etc. It is specically designed
to help car owner, repair workshop, battery factory use battery test
instrument properly and determine whether the battery is normal or
not.

7.2.2 Test Environment
7.2.2.1 Test environment
Inside the vehicle test indicates that the battery connects to loading
devices, such as engine, etc. After doing battery test, it can perform
charging system and actuation system test, which is proceeded as a
whole simultaneously. Charging system and actuation system test is
not required but must not be performed before battery test. Because it
is difcult for vehicle technicians to judge where is faulty exactly if they
have the faintest idea of battery’s status itself.
Outside the vehicle test indicates that the battery is disconnected
from all loading devices on vehicles. Therefore, only battery test is
supported in this condition.
7.2.2.2 Battery status and description
There are mainly 5 states as follows:
No. States Descriptions
1 Good battery Indicates battery is normal.
2 Replace battery
Indicates that battery is aged or becomes
rejected, or battery life cycle approaches to
be exhausted. In this case, battery voltage
appears to be normal, but battery itself is
not well, i.e. battery polarity board has been
completely vulcanized or aged. Please
replace battery immediately.
3 Good-recharge Stands for low battery. The battery is good
itself.
4 Charge-retest It is better for a few batteries to be fully
charged before testing in order to avoid
judging in error under special conditions.
5 Bad cell
Indicates one of the battery cells is bad and
can not work normally, but for which one is
bad, it can’t be veried. In this case, battery
voltage is generally lower than 11V, mainly
resulting from internal circuitry damage, such
as short circuit, open circuit, dummy weld
etc.

Fig. 7-19
Tap [OK], test data will be shown on the screen.
*Note: It is unnecessary to perform charging system and start system
test after finishing battery test, but battery test must be done before
undergoing charging system and starng system test.
7.2.4.3 Outside the vehicle test
It only applies to battery test and detecting oating electricity will be
ignored while performing battery test.
In Fig. 7-14, tap [Outside the vehicle] to select battery test standard.
The following operation steps are identical to Steps 6 ~ 7 in Chapter
7.2.4.2 Battery test. Please refer to it for details.
7.2.5 Precautions on battery test
For the purpose of getting accurate test results, unless otherwise
special required, all loads need to be power off such as headlamp,
engine etc. before testing battery.
The operating time required for charging system and actuation system
test varies from person to person. If the engine does not start or
accelerate within 30 seconds, the system will prompt you “receiving
timeout” and return to the initial status.
Whether Engine is off or not has no influence on charging and
actuation test result after increased speed is detected, but other loads
need to be powered off.
The accuracy of battery voltage, charging voltage, start voltage is
0.01V in test results; CCA (Cold Cranking Amps) precision is 5CCA.
Generally, charging voltage value is greater than starting voltage.
Charging voltage range is as follows: 13.8--14.5V for domestic vehicle;
13.3--15.5V for imported vehicles. The voltage varies with different
car models, so you have to judge based on related vehicle models.
In general, the DC voltage is stable, but it also varies with different
revolution speed.
Starting voltage range: The value higher than 9.6V is regular,
otherwise it is too low. Due to different situations, whether the starting
voltage is higher or not does not mean the vehicles or batteries are
faulty. For detailed faults, other special equipments are needed.
To validate the accuracy of the value, the best method is to collect
the signals of starting and charging voltage and observe it on an
oscillometer.
Generally, the voltage is lower than 11V for the bad cell battery, but it
is possible that the battery is completely exhausted or has a serious
low capacity. In this case, just recharge your battery. Bad cell always
happens when the loads on a stopping vehicle are turned on for a long
time.
Please note that it is normal for quick detecting of “Increase speed”
because it follows the theory of detecting “Increase speed”: If the
detected voltage is higher than the previous battery test voltage, the
system will prompt you a message of “Engine has been speeded”
It has no influence on test result in the event that engine’s output
voltage or engine revolution is not very stable. No matter whether
the vehicle is accelerated or not, the output voltage only differs within
0.2V.
While doing inside the vehicle test, Kelvin clip is always found to be
in poor contact. To remain it in good contact, please shake it several
62
Maximus 3.0 User's Manual
times before testing. Take down the battery connector, and test it
again, the value probably varies. The deviation may arise from battery
connector.
Pay more attention to connect the clip. The battery poles connect
with conductor, which makes the clip has a poor connection when
testing battery. A tolerance of dozens of CCA occurs if the clip is out of
position, or oil, dust attaches on the pole. The gear and main body of
clip should be fully matched with battery poles.
*Notes:
1. Battery poles inside the vehicle are enveloped by connectors, which
may produce some errors for test results. The tolerance results from the
resistance of connectors. The greater the resistance value is, the greater
the tolerance becomes. But generally, the tolerance does not aect the
test conclusion.
2. Tesng the baery separately generates an exact test result. The baery
box is a very useful auxiliary tool for quick test. If any problems were
found, test it separately for geng an exact test result.
7.3 Oscilloscope (Optional)
7.3.1 Introduction
The Scopebox is an optional add-on module of Maximus 3.0, including
automotive oscilloscope and automotive ignition waveform.
Automotive oscilloscope can make the auto repair technician quickly
judge the faults on automotive electronic equipment and wiring, and
the oscilloscope sweep speed is far greater than the signal frequency
of such vehicles, usually 5-10 times of the measured signal. The
automotive oscilloscope not only can quickly acquire the circuit signal,
but also can slowly display the waveform to observe and analyze.
It can also record and store the tested signal waveform which can
be recalled to observe for the fast signal, having great convenience
to failure analysis. Either high-speed signal (e.g.: Injection nozzle,
intermittent fault signal) or the slow-speed signal (e.g. the throttle
position change and the oxygen sensor signal) can be observed
through automotive oscilloscope in an appropriate waveform.
The electronic signal can be compared and judged via measuring
ve parameters indexes. The ve parameters are the amplitude (the
maximum voltage of signal), the frequency (the cycle time of signal),
the shape (the appearance of signal), the pulse width (the duty cycle
or the time range of signal), and the array (the repetition characteristic
of signal), which can be tested, displayed, saved by the automotive
oscilloscope. Via the waveform analysis can further detect the circuit
fault on sensors, actuators, circuits, and electronic control units, etc.

The trigger determines when the Scopebox starts to acquire data and
display a waveform. When a trigger is set up properly, it can convert
unstable displays or blank screens into meaningful waveforms.
When the Scopebox starts to acquire a waveform, it collects enough
data so that it can draw the waveform to the left of the trigger point.
The Scopebox continues to acquire data while waiting for the trigger
condition to occur. After it detects a trigger, the Scopebox continues to
acquire enough data so that it can draw the waveform to the right of
the trigger point.
User can make some settings directly by tapping < or > next to
options.

Channel: To select the channel source.
Volts/DIV: It is dened as “Volts/Division” and mainly used to change
the resolution.
Coupling: Trigger coupling determines what part of the signal passes
to the trigger circuit. AC, DC and Ground are included:
• AC: Blocks the DC component of the input signal.
• DC: Passes both AC and DC components of the input signal.
• Ground: Disconnects the input signal.
Probe: When using a probe, the Scopebox allows you to select the
attenuation factor for the probe. The attenuation factor changes the
vertical scaling of the Scopebox so that the measurement results
reect the actual voltage levels at the probe tip.

7.4 Ignition (Optional)
The ignition system is the system which has greatest impact on
the performances of gasoline engine, as the statistical data shows
that nearly half of the failures are caused by poor work of electrical
system. And the performance tests of engine often start from the
ignition system. Nowadays ignition system includes distributor and
distributorless. Distributorless includes independent ignition and
simultaneous ignition.
1. Distributor ignition system i.e. contact breaker with contact-
controlled ignition system (commonly known as the platinum)
and contact breaker with noncontact-controlled ignition system
combined with magnet, hall components or infrared.
2. Independent ignition system: crankshaft sensor send out the
ignition timing signal and cylinder identification signal so that the
ignition system can send out ignition signal to specied cylinder in
specied time, each cylinder has its independent ignition coil.
3. Simultaneous ignition system: two cylinders share one ignition
coil, when two cylinder pistons reach top dead center at the same
time (one is compression, another is the exhaust), two spark plugs
will be ignited at the same time, at this time, the ignition for the
former cylinder is in high-pressure low temperature gas mixture,
the ignition is valid, while for the latter one is in low-pressure high
temperature exhaust gas, the ignition is invalid.
Maximus 3.0 can test and analyze the secondary signal for various
engine ignition systems.
The Ignition module utilizes the same hardware device as the Scope
module.
7.4.1 Secondary-distributor ignition analysis
Connections: Plug the BNC end of secondary ignition pickup into CH1/
72
Maximus 3.0 User's Manual
CH2/CH3/CH4 channel of Scopebox, then connect the high-voltage
clip to high-voltage line, and crocodile clips to ground.
*Tips: Common ignion sequence (the specic sequence is subject to the
actual engine ignion sequence)
Four-stroke in-line four-cylinder: 1-2-4-3, or 1-3-4-2
Four-stroke in-line six-cylinder: 1-5-3-6-2-4, or 1-4-2-6-3-5
Four-stroke in-line eight-cylinder: 1-8-4-3-6-5-7-2
Five-cylinder: 1-2-4-5-3
V 6 engine: generally speaking, based on the person sing on the driver
cab, if the right side cylinder numbers on the right side, from the front
to the back are as follows: 1, 3, 5; and the cylinder numbers on the left
side, from the front to the back are as follows: 2, 4, 6; then the ignion
sequence is: 1-4-5-2-3-6. If the cylinder numbers on the right side, from
the front to the back are as follows: 2, 4, 6; and cylinder numbers on the
le side, from the front to the back are as follows: 1, 3, 5; then the ignion
sequence is: 1-6-5-4-3-2.
Figure 7-36 below shows the normal ignition waveform of distributor
ignition system, the upper one is the secondary waveform, and the
lower one is the primary waveform.
The secondary waveform
A section is contact open period; B section is make contact period,
which is the magnetizing eld of ignition coil.
Fig. 7-36
1) Contact break point: the primary circuit of ignition coil cut off, the
secondary voltage was sensed and increased sharply
2) Ignition voltage: secondary coil voltage overcome the damper of
high voltage line, the contact breaker gap and the spark plug gap to
release magnetizing energy, 1-2 section is the breakdown voltage
3) Spark voltage: For the capacitor discharge voltage
4) Ignition voltage pulse: For the charge and discharge sections
5) Spark line: The inductance discharge process, i.e. the mutual
inductance voltage of ignition coil maintains the conduction of
secondary circuit.
6) Contact point close the current ow into primary coil, the primary
coil oscillates due to the mutual inductance.
Primary ignition waveform
Section a shows the voltage oscillation on the primary circuit due to
Maximus 3.0 User's Manual
73
the magnetic induction of spark in the duration;
Section b shows the damped oscillation generated by remaining
magnetic eld energy after the spark;
Section c shows the make contact magneting period of primary coil.
Seen from the waveform, the amplitudes of breaker contact closed
angle, break angle and breakdown voltage and spark voltage are very
clear, besides, the spark delay period and two oscillations can also
be tested. For the ignition system without faults, compared with the
whole cycle, the contact closed angle just 45%-50% (four-cylinder),
63%-70% (six-cylinder), or 64%-71% (eight-cyliner); the breakdown
voltage is over 15kv; the spark voltage is about 9kV, the spark period
is greater than 0.8ms. If these values or waveform are abnormal, it
means there is fault or the system needs to be adjusted.
7.4.2 Secondary-simultaneous ignition analysis
Connections: Plug the BNC end of secondary ignition pickup into CH1/
CH2/CH3/CH4 channel of Scopebox, then connect the high-voltage
clip to high-voltage line, and crocodile clips to ground.
Connection as shown in gure 7-37:
Fig. 7-37
Fig. 7-38 below shows the valid and invalid ignition waveforms. Under
the working status of valid ignition, the breakdown voltage and spark
voltage are higher because the cylinder is lled with fresh combustible
mixture gas, which has a lower ionization level and vice versa.
Fig. 7-38
7.4.3 Secondary-direct ignition analysis
Connection:
1) When the high-voltage wire is exposed, plug the BNC end of
secondary ignition pickup into CH1/CH2/CH3/CH4 channel of
Scopebox, then connect the high-voltage clip to high-voltage line,
and crocodile clips to ground.
2) If no high-voltage wire exposes, dismantle ignition coil of tested
cylinder and use direct ignition extension cord. Connect one end to
ignition coil which should be grounded via direct ignition grounding
wire, and insert the other end into cylinder to joint with spark plug.
Then plug the BNC end of secondary ignition pickup into CH1/CH2/
CH3/CH4 channel of Scopebox, then connect the high-voltage clip
to high-voltage line, and crocodile clips to ground.
Connections are shown in Fig. 7-39:
74
Maximus 3.0 User's Manual
Fig. 7-39
Fig. 7-40 shows the normal secondary (the upper one) and (the lower
one) primary ignition waveform of direct ignition system. Beause the
on/off of primary circuit is not opening/closing of mechanical contact,
but the conduction of transistor. The primary voltage has no obvious
oscillations within the duration, but the voltage increases during the
magnetization process due to current limiting, and this change can
cause corresponding uctuations of secondary voltage line as a result
of induction of ignition coil.
Fig. 7-40
7.4.4 Waveform analysis mode
The ignition secondary single-cylinder waveform test is mainly used to:
a. Analyze the ignition dwell angle of single cylinder.(ignition coil
charging time)
b. Analyze the capability of ignition coil and secondary high tension
circuit (from ignition line to ignition voltage line).
c. Find the improper mixture A/F ratio of single cylinder (from
combustion line).
d. Analyze the capability of capacitance (platinum or ignition system).
e. Find the spark plug that causes misfire of the cylinder (from
combustion line).
This test can provide very meaningful information about the
combustion quality for each cylinder. If necessary, this test can also
be performed during driving. Since the secondary ignition waveform
is signicantly affected by different engines, fuel systems and ignition
conditions, it is useful for detecting the faults of engine mechanical
parts, fuel system components, and ignition system components.
Different parts of the waveform can specify that some components and
systems on the specic cylinder have faults. Refer to the instructions
for various parts of waveform for the related component working status
of specic waveform section.
Test methods and conditions:
Start the engine or drive the vehicle accroding to the driving
performance fault or poor ignition, etc. Confirm the consistence of
judgement standard (the amplitude, frequency, shape and pulse
width, etc., for each cylinder), check the fault of the waveform for
corresponding components.
Waveform results: observe the ignition coil at the beginning of
charging, the relative consistent falling edge represents the dwell
angle and ignition timing of each cylinder are precise.
Maximus 3.0 User's Manual
75
Ignition line:
Observe the height consistence of flashover voltage. Too high
ashover voltage (even out of the oscilloscope screen) represents a
high resistance existed in the ignition secondary circuit (for example,
open circuit, or damaged spark plug or high voltage line, or too
large time gap on spark plug), while the too short sparking voltage
represents the resistance of ignition secondary circuit is lower than
normal value (due to pollutant and broken spark plug or the high
voltage line of spark plug has electrical leakage, etc.).
Spark or combustion voltage:
Observe the consistence of spark or combustion voltage, as it
represents the consistence of spark plug and the air-fuel ratio of each
cylinder. In case that the mixing ratio is too lean, the combustion
voltage will be lower than normal value.
Combustion line:
Observe the spark or the combustion line which shall be clean with
few clutter, as lots of clutter indicates the cylinder has poor ignition
due to ignite too early, damaged nozzle, pollutant spark plug, or other
reasons. The duration of combustion line indicates the mixing ratio of
the cylinder is abnormal lean or rich. Too long combustion line (usually
greater than 2ms) represents the mixing ratio is rich, whereas too
short of combustion line (usually less than 0.75ms) represents the
mixing ratio is lean.
Ignition coil oscillation:
Observe at least two oscillation waveforms after the combustion
line, which will be better if more than three oscillation waveforms, as
it represents the ignition coil and capacitor (on Platinum or ignition
system) are normal.
Primary voltage analysis
According to the faulty primary voltage waveform collected by the
ignition analysis, the related components and mechanical equipment
status of ignition system electrical circuit can be analyzed, which
provides a reliable basis for the adjustment and maintenance of power
circuit to avoid the blind demolition.
The waveform shown on Fig. 7-41, appears a lot of clutter on the
contact break point, which is obviously caused by the serious erosion
on contact break point. It can be veried via burnishing the contact or
changing the circuit breaker.
Fig. 7-41
For the primary voltage waveform shown on Fig. 7-42, the damped
attenuation cycles obviously reduced on the spark period, the
amplitude became lower, which is evidently caused by capacitor
leakage.
Fig. 7-42
The waveform on Fig. 7-43 shows the accidental pumping during
contact closing period. The irregular beating is caused by insufcient
spring force.
76
Maximus 3.0 User's Manual
Fig. 7-43
The curve on Fig. 7-44 shows the contact angle is too small during the
magnetizing period, which is caused by too large contact gap.
Fig. 7-44
A lot of clutter will be displayed on the horizontal section of primary
waveform if contact has poor grounding, as shown below gure 7-45.
Fig. 7-45
Fig. 7-46 shows the fault of low-voltage waveform in electronic ignition
system. The voltage does not rise during magnetizing, which indicates
that the effect of limitation of the circuit failed and no components on
distributorless ignition system can be adjusted. When this waveform is
abnormal, you can only replace the ignition coils, igniter, ignition signal
generator and cam position sensor, etc., one by one, to nd out the
faulty component or module.
Fig. 7-46
The secondary waveform is also affected by the spark plug, the
combustion process, mixture gas composition, the engine thermal
state of the ignition coil, etc., which is more complicated. The following
lists a large number of measured secondary faulty waveform for
reference. Since various factors lead to the failures, Fig. 7-47 just
shows the major possible factors for the failures.
