1. Introduction
1.1 Vehicle Coverage
This diagnostic tool is specially designed to work with all OBD II compliant
vehicles, including Controller Area Network (CAN). It is required by EPA that
all 1996 and newer vehicles (cars and light trucks) sold in the United States
must be OBD II compliant and this includes all American, Asian and European
vehicles.
A small number of 1994 and 1995 model year gasoline vehicles are OBD II
compliant. To verify if a 1994 or 1995 vehicle is OBD II compliant, check the
following:
1. Vehicle Emissions Control Information (VECI) Label. It is located under the
hood or by the radiator of most vehicles. If the vehicle is OBD II compliant,
the label will designate OBD II Certied.
2. Government regulations mandate that all OBD II compliant vehicles must
have a “common” 16-pin Data Link Connector (DLC).
*Note: Some 1994 and 1995 vehicles have 16-pin connectors but are not OBD II
compliant. Only those vehicles with a Vehicle Emissions Control Label stating OBD II
Certied are OBD II compliant.
2
LAUNCH
1.2 On-Board Diagnostics (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, which will oer three pieces of such valuable
information:
• Whether the Malfunction Indicator Light (MIL) is commanded “on” or “o”;
• Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
• Readiness Monitor status.
1.3 OBD II Denitions
The following terms and their denitions are related to OBD II systems. Read
and reference this list as needed to aid in the understanding of OBD II systems.
EOBD - European On-Board Diagnostics. Essentially the same as OBD II, with
the same Data Link Connector and Communication Protocols.
Communication Protocols - Allows dierent systems and sensors in a vehicle to
communicate. There are currently ve protocols:
• CAN Bus
• J1850 VPW
• ISO 9141-2
• J1850 PWM
• ISO 14230 KWP
Powertrain Control Module (PCM) -- The PCM is the OBD II accepted term
for the vehicle’s “on-board computer.” In addition to controlling the engine
management and emissions systems, the PCM also participates in controlling
the powertrain (transmission) operation. Most PCMs also have the ability to
communicate with other computers on the vehicle (ABS, ride control, body, etc.).
DLC -- Data Link Connector. The 16-cavity connector on the vehicle that allows
communication between the computer system and the diagnostic tool.
MIL -- Malfunction Indicator Light. The vehicle’s “Check Engine” warning light
that activates when a DTC is stored.
DTC -- Diagnostic Trouble Code. A code stored in the computer system’s
memory, which helps to identify the fault condition that is causing the MIL to
activate.
Freeze Frame Data -- Operating conditions that are stored when a DTC is
stored.
PID -- Parameter Identification Data. Data returned by the vehicle’s control
3
LAUNCH
modules to the diagnostic tool.
Monitors -- Monitors are “diagnostic routines” programmed into the PCM. The
PCM utilizes these programs to run diagnostic tests, and to monitor operation
of the vehicle’s emissions-related components or systems to ensure they are
operating correctly and within the vehicle’s manufacturer specications.
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.
Trip - A Trip for a particular Monitor requires that the vehicle is being driven in
such a way that all the required “Enabling Criteria” for the Monitor to run and
complete its diagnostic testing are met. The “Trip Drive Cycle” for a particular
Monitor begins when the ignition key is turned “On.” It is successfully completed
when all the “Enabling Criteria” for the Monitor to run and complete its diagnostic
testing are met by the time the ignition key is turned “Off.” Since each of the
fifteen monitors is designed to run diagnostics and testing on a different part
of the engine or emissions system, the “Trip Drive Cycle” needed for each
individual Monitor to run and complete varies.
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.
*Note: Do not confuse a “Trip” Drive Cycle with an OBD II Drive Cycle. A “Trip” Drive
Cycle provides the “Enabling Criteria” for one specific Monitor to run and complete
its diagnostic testing. An OBD II Drive Cycle must meet the “Enabling Criteria” for all
Monitors on a particular vehicle to run and complete their diagnostic testing.
Warm-up Cycle - Vehicle operation after an engine off period where engine
temperature rises at least 40°F (22°C) from its temperature before starting, and
reaches at least 160°F (70°C). The PCM uses warm-up cycles as a counter to
automatically erase a specic code and related data from its memory. When no
faults related to the original problem are detected within a specied number of
warm-up cycles, the code is erased automatically.
Fuel Trim (FT) - Feedback adjustments to the base fuel schedule. Short-term
4
LAUNCH
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 dierences and gradual changes that occur over time.
1.4 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:
P0201 - Injector circuit malfunction, Cylinder 1
5
LAUNCH
1.5 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. It is usually located 12 inches from the center of the instrument
panel, under or around the driver’s side for most vehicles. For some vehicles
with special designs, the DLC location may vary.
Refer to the following gure for location.
A- Opel, Volkswagen, Audi
B- Honda
C- Volkswagen
D- Opel, Volkswagen, Citroen
E- Changan
F- Hyundai, Daewoo, Kia, Honda, Toyota, Nissan, Mitsubishi, Renault, Opel,
BMW, Mercedes-Benz, Mazda, Volkswagen, Audi, GM, Chrysler, Peugeot,
Regal, Beijing Jeep, Citroen and other most popular models
If the DLC cannot be found, refer to the vehicle’s service manual for the location.

rewall under the hood.
• In general, vehicle identification numbers are standardized - all contain 17
characters. VIN characters may be capital letters A through Z and numbers 1
through 0; however, the letters I, O and Q are never used in order to avoid mistakes
of misreading. No signs or spaces are allowed in the VIN.
