I am glad to see this thread, but Sir Ridenour did not have to give me the credit, This is something that will help out all of the members.

To all GA Forum Members, please add any newer codes if there are new ones. I pulled these codes from my manual that goes up to the 1998 model. If there are more codes it will only benefit all of the members to have a complete listing.

Thanks,
Hoags

Heres the ODB-I procedure .

This is a picture of the Assembly Line Diagnostic Link (ALDL) connector or Data Link Connector (DLC). These two connectors are located just under the steering wheel, might be covered up with a cover btw. Either of these could have been used on your 1985-98 pontiac GA.


Codes can be read by grounding test terminal B. The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). This is the terminal to the right of terminal B on the top row of the ALDL connector.

Once the terminals have been connected, the ignition switch must be moved to the ON position with the engine not running.

The Service Engine Soon or Check Engine light should be flashing. If it isn't, turn the ignition OFF and remove the jumper wire. Turn the ignition ON and confirm that light is now on. If it is not, replace the bulb and try again. If the bulb still will not light, or if it does not flash with the test terminal grounded, the system should be diagnosed by an experienced technician. If the light is OK, proceed as follows.

The codes stored in memory may be read through counting the flashes of the dashboard warning lamp. The dash warning lamp should begin to flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code, its presence indicates the PCM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent.

After Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest.

The order of codes in the memory does not indicate the order of occurrence.

If there are no codes stored, but a driveability or emissions problem is evident, the system should be diagnosed by an experienced technician.
If one or more codes are stored, record them.
Switch the ignition OFF when finished with code retrieval or scan tool readings.

On some models, 94-96, they will need scanned with a scan tool.
