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.
