VEHICLE SERVICE INFORMATION
The following is a list of web sites and phone numbers where electronic
engine control diagnostic information is available.
✓ Some manuals may be available at your local dealer, auto parts
The original on-board diagnostics (OBD I) lacked consistency in
communication and interface while allowing different interpretations amongst
vehicle manufacturers. Ford and Chrysler used different types of engine control
computers and data link connectors, and GM varied the trouble codes and
communication protocols from year-to-year.
The tables below highlight changes for GM, Ford, and Chrysler. If this seems
confusing; don’t worry. Your tool makes it easy. Based on the VIN information
selected during Scan Tool setup, the processor is automatically recognized. All
you have to do is choose the correct adapter cable and jumper wires (if
necessary). Details on adapter cables and jumper wires may be found in

OBD II stands for On-Board Diagnostics version II. OBD II is a system that the
Society of Automotive Engineers (SAE) developed to standardize automotive
electronic diagnosis. Technicians now can use the same tool to test any OBD
II compliant vehicles without special adapters. The SAE established guidelines
that provide:
• a universal diagnostic test connector, called the data link connector (DLC),
with dedicated pin assignments.
• a standardized location for the DLC, visible under the dash on the driver’s
side.
• a standardized list of diagnostic trouble codes (DTCs) used by all
manufacturers.
• a standardized list of parameter identification (PID) data used by all
manufacturers.
• the ability of the vehicle system to record a freeze frame of the operating
conditions when a fault occurs.
• expanded diagnostic capabilities that records a code whenever a condition
occurs that effects vehicle emissions.
• the ability to clear stored codes from vehicle memory with the scan tool.
In addition, SAE has published hundreds of pages of text defining a standard
communications protocol that establishes the hardware, software, and circuit
parameters of OBD II systems. Unfortunately, vehicle manufacturers have
different interpretations of this standard communications protocol. As a result,
the generic OBD II communications scheme used will vary, depending on the
vehicle.
SAE publishes recommendations, not laws, but the Environmental Protection
Agency (EPA) and California Air Resources Board (CARB) made many of
SAE’s recommendations legal requirements that vehicle manufacturers were
required to phase in over a three-year period. Beginning in 1994, vehicles with
a new engine management computer – about 10% of each manufacturers fleet
– were supposed to comply with OBD II standards. For 1995, OBD II systems
were to appear on about 40% of the new vehicles sold in the USA. Some of the
1994-1995 OBD II systems were not fully compliant, so the Government
granted waivers to give manufacturers time to fine-tune their systems.
Beginning in 1996, most of the new vehicles sold in the USA were fully OBD II
compliant.
DIAGNOSTIC LINK CONNECTORS (DLC)
The Data Link Connector (DLC) allows the scan tool to communicate with the
vehicle’s computer(s). Before OBD II, manufacturers used different data link
connectors to communicate with the vehicle. The proper DLC adapter cable
must be used to connect the tool to the vehicle. Also, the vehicle’s DLC may be
found in several different places and have many different configurations. The
following describes the DLCs used by Ford, GM and Chrysler. The DLC location
and types for domestic vehicles can be looked up in the charts in “Appendix
Beginning in 1996, vehicles sold in
the United States use the J1962
(OBD II) DLC, a term taken from a
physical and electrical specification
number assigned by SAE (J1962).
The DLC should be located under
the dashboard on the driver side of
the vehicle. If the DLC is not located under the dashboard as stated, a decal
describing its location should be attached to the dashboard in the area the DLC
should have been located.
Because the OBD II J1962 connector has power and ground, you only need a
single cable connection to the tool for both power and tool communications.
Attach the OBD II adapter cable to the extender cable, both supplied with the
tool, to connect the tool. Certain pins in the connector are reserved
Ford used three types of DLCs with their historic (OBD I) systems. Refer to
“Appendix A - Data Link Connectors" for the adapter cable needed for your
vehicle.
