Retrieving codes
- Locate the diagnostic connector in or under the glove compartment. (Summit models in fuse box)
- Connect analog voltmeter to upper LH (+) and lower RH (-) terminals
- Most Summit models, connect voltmeter (+) to upper LH of the 12 pin connector and (-) to the 2 middle
- SOME Station wagon models you may have to ground the upper LH of the 16 pin connector
- Turn the ignition on, then watch the sweeps of the vlotmeter
- Long sweeps are tens and shirt sweeps are ones.
- Continuous short sweeps indicated no codes.
Clearing Codes
Disconnect the battery from the Negative terminal to clear codes.

The check engine light illuminates while driving on my 1990 Eagle Talon TSI turbo all wheel drive, and some times it turns off on its own after driving another approximately 20 miles and most of the time stays on until I reach home.
I have tried to retrieve the diagnostic code(s) with a test light inserted in contact 1 of the diagnostic connector, the other end on a good ground and with ignition key on, but the test light gives me no flashes!
Of course I disconnect the battery to get rid of the check engine light, but it comes back again at random times.
Any idea why the test light won’t flash the codes? My test light is good and I am pretty sure I put it on the number 1 pin of the diagnostic connector.
hello
i m meeting same issue.
did you solve it
maybe you have to ebter into diag mode to get flashes.
so you need to find out how to do so from eagle
regards
