ON-BOARD DIAGNOSTICS
The original on-board diagnostics (OBD I) lacked consistency in communication and interface while allowing different interpretations amongst vehicle manufacturers. Ford used several types of engine control computers, Chrysler used several types of data link connectors and GM varied the trouble codes and communication protocols from year-to-year.
The following tables 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 “Diagnostic Link Connectors (DLC)” on page 1-4.

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 established SAE guidelines are:
•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 |
1 |
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 A – Data Link Connectors” .
OBD II (J1962) DLC
Beginning in 1996, vehicles sold in the United States use the J1962 DLC, a
term taken from a physical and electrical specification number
assigned by SAE (J1962). OBD II defines the physical and electrical
specification for the DLC. 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.

Four Vehicle Options are available: General Motors, Ford, Chrysler and Global OBD II. Global OBD II does not require additional information and takes you directly to the function list. The other three require additional information so that the tool and vehicle can communicate. For example, select GENERAL MOTORS.
The menus provide a list of choices and reference the v e h i cl e ’s V I N w h e r e applicable. The VIN is visible from outside the vehicle by looking through t h e b a se o f t h e f ro n t windshield at the top of the dashboard on the driver’s s i d e .

This section covers all OBD II compliant vehicles. Non OBD II vehicles manufactured by GM, Ford and Chrysler are covered in Parts 4, 5 and 6, respectively.
If an Operating Error message displays, refer to “Error Messages” on page 7-3 and check the following :
make sure the OBD II connector is securely attached, and the ignition key is ON. Cycle the ignition key to OFF for 10 seconds, then ON. This may be required to reset the computer. If required, select YES to try again.
the vehicle fails to link because it does not support OBD II diagnostics. Check the emissions label on the vehicle for OBD II compliance.
On the initial link to the vehicle, the scan tool checks the status of the
I/M Monitors and displays it regardless of the function selected.

I/M READINESS
The I/M Readiness (Inspection and Maintenance) function is used to check the operations of the Emission System on OBDII vehicles. I/M Readiness is an excellent function to use prior to having a vehicle inspected for compliance to a state emissions program.
During normal driving conditions, the vehicle’s computer scans the emission system. After a specific amount of drive time (depending on vehicle), the computer’s "monitors" will decide if the vehicles emission system is working correctly or not. When the "monitors" record:
•"OK" and check engine light has not come on - vehicle will likely pass emissions test and the system being checked is working properly.
•"INC" (Incomplete) - vehicle was not driven enough and needs to be driven until monitors record "READY."
•"N/A" - vehicle does not support that monitor.
Some states MAY NOT require all monitors to be listed as “READY” to pass the emissions test. Check with state testing site for exact requirements. All states will fail a vehicle who has the "check engine light" lit at time of test.
Depending on vehicle, disconnecting or a discharged battery may erase trouble codes and clear status monitors.
The vehicle may support more than one type of I/M Readiness. The first type shows the status of the monitors since the DTCs were last erased. They are displayed under the heading SINCE DTCs CLEARED. The second type shows the status of the monitors since the start of the current drive cycle, and are displayed under the heading THIS DRIVING CYCLE. If the monitors are not supported for THIS DRIVING CYCLE, then the scan tool only shows monitors for SINCE DTCs CLEARED with no header on line 1.
