LAUNCH GEAR SCAN User's Manual
2. General Information
2.1 On-Board Diagnostics (OBD) II
The first generation of On-Board Diagnostics (OBD I) was developed by the
California Air Resources Board (ARB) and implemented in 1988 to monitor some
of the emission control components on vehicles. As technology evolved and the
desire to improve the On-Board Diagnostic system increased, a new generation
of On-Board Diagnostic system was developed. This second generation of On-
Board Diagnostic regulations is called “OBD II”.
The OBD II system is designed to monitor emission control systems and key
engine components by performing either continuous or periodic tests of specic
components and vehicle conditions. When a problem is detected, the OBD II
system turns on a warning lamp (MIL) on the vehicle instrument panel to alert
the driver typically by the phrase of “Check Engine” or “Service Engine Soon”.
The system will also store important information about the detected malfunction
so that a technician can accurately nd and x the problem. Here below follow
three pieces of such valuable information:
1) Whether the Malfunction Indicator Light (MIL) is commanded ‘on’ or ‘off’;
2) Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
3) Readiness Monitor status.
2.2 Diagnostic Trouble Codes (DTCs)
OBD II Diagnostic Trouble Codes are codes that are stored by the on-board
computer diagnostic system in response to a problem found in the vehicle. These
codes identify a particular problem area and are intended to provide you with a
guide as to where a fault might be occurring within a vehicle. OBD II Diagnostic
Trouble Codes consist of a five-digit alphanumeric code. The first character,
a letter, identifies which control system sets the code. The second character,
a number, 0-3; other three characters, a hex character, 0-9 or A-F provide
additional information on where the DTC originated and the operating conditions
that caused it to set. Here below is an example to illustrate the structure of the
digits:

Figure 2-1
2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is typically a 16-
pin 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.

Figure 2-2
2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBD II system is the Readiness Monitors, which
are indicators used to find out if all of the emissions components have been
evaluated by the OBD II system. They are running periodic tests on specific
systems and components to ensure that they are performing within allowable
limits.
Currently, there are eleven OBD II Readiness Monitors (or I/M Monitors) dened
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
5
LAUNCH GEAR SCAN User's Manual
EN
6) Secondary air Injection
7) Heated Catalyst
8) A/C system
2.5 OBD II Monitor Readiness Status
OBD II systems must indicate whether or not the vehicle’s PCM’s monitor
system has completed testing on each component. Components that have been
tested will be reported as “Ready”, or “Complete”, meaning they have been
tested by the OBD II system. The purpose of recording readiness status is to
allow inspectors to determine if the vehicle’s OBD II system has tested all the
components and/or systems.
The Powertrain Control Module (PCM) sets a monitor to “Ready” or “Complete”
after an appropriate drive cycle has been performed. The drive cycle that
enables a monitor and sets readiness codes to “Ready” varies for each
individual monitor. Once a monitor is set as “Ready” or “Complete”, it will remain
in this state. A number of factors, including erasing of Diagnostic Trouble Codes
(DTCs) with a code reader or a disconnected battery, can result in Readiness
Monitors being set to “Not Ready”. Since the three continuous monitors are
constantly evaluating, they will be reported as “Ready” all of the time. If testing
of a particular supported non-continuous monitor has not been completed, the
monitor status will be reported as “Not Complete” or “Not Ready.”
In order for the OBD monitor system to become ready, the vehicle should be
driven under a variety of normal operating conditions. These operating conditions
may include a mix of highway driving and stop and go, city type driving, and at
least one overnight-off period. For specic information on getting your vehicle’s
OBD monitor system ready, please consult your vehicle owner’s manual.
2.6 OBD II Denitions
Powertrain Control Module (PCM) -- OBD II terminology for the on-board
computer that controls engine and drive train.
Malfunction Indicator Light (MIL) -- Malfunction Indicator Light (Service Engine
Soon, Check Engine) is a term used for the light on the instrument panel. It
is to alert the driver and/or the repair technician that there is a problem with
one or more of vehicle’s systems and may cause emissions to exceed federal
standards. If the MIL illuminates with a steady light, it indicates that a problem
has been detected and the vehicle should be serviced as soon as possible.
Under certain conditions, the dashboard light will blink or ash. This indicates a
severe problem and flashing is intended to discourage vehicle operation. The
vehicle onboard diagnostic system cannot turn the MIL off until the necessary
repairs are completed or the condition no longer exists.
6
LAUNCH GEAR SCAN User's Manual
DTC -- Diagnostic Trouble Codes (DTC) that identifies which section of the
emission control system has malfunctioned.
Enabling Criteria -- Also termed Enabling Conditions. They are the vehicle-
specic events or conditions that must occur within the engine before the various
monitors will set, or run. Some monitors require the vehicle to follow a prescribed
“drive cycle” routine as part of the enabling criteria. Drive cycles vary among
vehicles and for each monitor in any particular vehicle. Please refer to the
vehicle’s factory service manual for specic enabling procedures.
OBD II Drive Cycle -- A specific mode of vehicle operation that provides
conditions required to set all the readiness monitors applicable to the vehicle to
the “ready” condition. The purpose of completing an OBD II drive cycle is to force
the vehicle to run its onboard diagnostics. Some form of a drive cycle needs to
be performed after DTCs have been erased from the PCM’s memory or after
the battery has been disconnected. Running through a vehicle’s complete drive
cycle will “set” the readiness monitors so that future faults can be detected. Drive
cycles vary depending on the vehicle and the monitor that needs to be reset. For
vehicle specic drive cycle, consult the service manual.
Freeze Frame Data -- When an emissions related fault occurs, the OBD II
system not only sets a code but also records a snapshot of the vehicle operating
parameters to help in identifying the problem. This set of values is referred to
as Freeze Frame Data and may include important engine parameters such as
engine RPM, vehicle speed, air ow, engine load, fuel pressure, fuel trim value,
engine coolant temperature, ignition timing advance, or closed loop status.
Fuel Trim (FT) - Feedback adjustments to the base fuel schedule. Short-term
fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim
refers to much more gradual adjustments to the fuel calibration schedule than
short-term trim adjustments. These long-term adjustments compensate for
vehicle differences and gradual changes that occur over time.
