LAUNCH X-431 Throttle User Manual 70 9.3 Sensor Simulation 9.3.1 Connections 1. Firstly, power the X-431 Throttle tablet on. 2. Plug one end of the sensor test cable (black) into the “COM” interface of the sensorbox, and then 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 the other end to the test probe or electronic control converting cable. Note: Choose corresponding cables and test probes according to different terminals. 9.3.2 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 (refer to Chapter 9.3.1 for details), launch X-431 Throttle application and enter the Job menu interface, then tap “Toolbox” -> “Sensor” to enter the test selection screen. See Fig. 9-2.

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 , X-431 Throttle will output a waveform as desired. Warning: Just draw a complete periodic waveform (when it is output, 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. In Fig. 9-2, tap “Hand-painted waveform simulation”, a screen similar to Fig. 9-8 will appear. Fig. 9-8 Button descriptions: []: Save the current waveform. []: Loads the previously saved hand-drawn waveform. []: Clear all hand-drawn waveform. []: Click to call out the predefined waveform for reference. []: Continues the following operation. 9.3.3 Precautions on checking vehicle sensor y Hold the connector when plugging or unplugging it. Do not pull the cable for
LAUNCH X-431 Throttle User Manual 75 unplugging. y At first check the fuse, fusible line and terminals. Then check others after eliminating these faults. y When measuring voltage, the ignition switch should be on and the battery voltage should not be less than 11V. y When measuring voltage, please shake the lead lightly in the vertical and horizontal direction for more precision. y When checking whether there is open in the line, disconnect the CEU and the relevant sensor at first, then measure the resistance among the ports of sensor in order to determine whether open-circuit / contact fault exists or not. y 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. y 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. y 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. y 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. y When checking the continuity of the terminals, contacts and leads, the method for measuring their resistances can be used. y Check the faults in the terminals of the CEU to sensors, relays, etc. y 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.

For the magnetostriction knock sensor, it can also test the resistance by the “Resistance measurement” function; the resistance shall be compliant with the specified value (see specific service manual for the detailed data), otherwise, the knock sensor shall be replaced. (2) Checking for the output signal of knock sensor Unplug the wire connector of knock sensor, check voltage between knock sensor connector terminal and ground wire of knock, it should be output pulse voltage; otherwise, the knock sensor shall be replaced. Coolant temperature sensor testing (1) Resistance test for coolant temperature sensor On vehicle testing: Switch ignition “OFF” and unplug the wire connector of coolant temperature sensor, then use the “Resistance measurement” to test the Resistance between two terminals of sensor. The relationship between the resistance and the temperature is in inversely proportion (negative temperature coefficient), which shall be less than 1kΩ during warming up. 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
LAUNCH X-431 Throttle User Manual 78 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.

LAUNCH X-431 Throttle User Manual 80 11.2 Test Environment 11.2.1 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 difficult 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. 11.2.2 Battery status and description There are mainly 5 states as follows: No. States Descriptions1 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 cannot work normally, but for which one is bad, it can’t be verified. 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.

Charging system and starting system test While performing this test, the battery’s charging voltage value and starting voltage can be obtained in case of engine starting and accelerating. Based on the data, the system will judge whether battery’s charging and actuation status is normal or not. Tap in Fig. 11-7, a dialog box will pop up as Fig. 11-8. Fig. 11-8 After detecting engine starting, follow the instructions on the screen to increase the speed. The system begins to receive test data information after acceleration was detected, as shown in Fig. 11-9.
LAUNCH X-431 Throttle User Manual 85 Fig. 11-9 Tap [OK], test data will be shown on the screen. Notes: 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 starting system test. 11.4.3 Outside the vehicle test It only applies to battery test and detecting floating electricity will be ignored while performing battery test. On Fig. 11-4, tap [Outside the vehicle] to select battery test standard. The following operation steps are identical to Steps 6~7 in Chapter 11.4.2 Battery test. Please refer to it for details. 11.5 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
LAUNCH X-431 Throttle User Manual 86 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 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 affect the test conclusion. 2. Testing the battery separately generates an exact test result. The battery box is a very useful auxiliary tool for quick test.

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 five parameters indexes. The five 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.

It shows the voltage of a waveform record (on the vertical axis) as it varies over time (on the horizontal axis). Vertical Settings The trigger determines when the Scopebox starts to acquire data and display a
X-431 Throttle User Manual 93 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. Fig. 12-5 Options descriptions: Menu Comments/SettingsChannel To select the channel source. Volts/DIV It is defined 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 reflect the actual voltage levels at the probe tip.

X-431 Throttle User Manual 102 13 Automotive Ignition waveform 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 specified cylinder in specified 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. X-431 Throttle can test and analyze the secondary signal for various engine ignition systems. 13.1 Secondary-distributor 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. Tips: Common ignition sequence (the specific sequence is subject to the actual engine ignition 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 sitting on the driver cab, if
X-431 Throttle User Manual 103 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 ignition 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 left side, from the front to the back are as follows:1, 3, 5; then the ignition sequence is: 1－6－5－4－3－2. Figure 13-1 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 field of ignition coil. Fig. 13-1 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
X-431 Throttle User Manual 104 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 flow 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 the magnetic induction of spark in the duration; Section b shows the damped oscillation generated by remaining magnetic field 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. 13.2 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 figure 13-2:
X-431 Throttle User Manual 105 Fig. 13-2 Fig. 13-3 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 filled with fresh combustible mixture gas, which has a lower ionization level and vice versa. Fig. 13-3
X-431 Throttle User Manual 106 13.3 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. 13-4: Fig. 13-4 Fig. 13-5 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 fluctuations of secondary voltage line as a result of induction of ignition coil.
X-431 Throttle User Manual 107 Fig. 13-5 13.4 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 significantly 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 specific cylinder have faults. Refer to the instructions for various parts of waveform for the related component working status of specific waveform section. Test methods and conditions: Start the engine or drive the vehicle according to the driving performance fault or
X-431 Throttle User Manual 108 poor ignition, etc. Confirm the consistence of judgment 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. Ignition line: Observe the height consistence of flashover voltage. Too high flashover 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. 13-6, appears a lot of clutter on the contact break point, which is obviously caused by the serious erosion on contact break point. It
X-431 Throttle User Manual 109 can be verified via burnishing the contact or changing the circuit breaker. Fig. 13-6 For the primary voltage waveform shown on Fig. 13-7, the damped attenuation cycles obviously reduced on the spark period, the amplitude became lower, which is evidently caused by capacitor leakage. Fig. 13-7 The waveform on Fig. 13-8 shows the accidental pumping during contact closing period. The irregular beating is caused by insufficient spring force. Fig. 13-8 The curve on Fig. 13-9 shows the contact angle is too small during the magnetizing period, which is caused by too large contact gap.
X-431 Throttle User Manual 110 Fig. 13-9 A lot of clutter will be displayed on the horizontal section of primary waveform if contact has poor grounding, as shown below figure 13-10. Fig.13-10 Fig. 13-11 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 find out the faulty component or module. Fig. 13-11 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
X-431 Throttle User Manual 111 failures, Fig. 13-12 just shows the major possible factors for the failures.
