mileage have not been programmed, a DTC will be set in the ABS, Airbag and the
SKIM modules. In addition, if the vehicle is equipped with a Sentry Key Immobilizer
Module (SKIM), Secret Key data must be updated to enable starting. Refer to
GENERAL INFORMATION section for programming information for the PCM, SKIM
and the Transponder (ignition key).
1. Inspect the vehicle to ensure that all components related to the repair are connected
properly.
2. With the DRBIIIt, Clear DTC's.
3. Perform generator output test. Refer to the appropriate service information as necessary.
4. Start the engine and set engine speed to 2000 RPM for at least thirty seconds.
5. Turn the ignition OFF.
6. Turn the ignition ON, with the engine not running.
7. With the DRBIIIt, Read the DTC's. If the DTC returns, or any other symptom or DTC is
present, refer to the symptom list for further diagnostic testing procedures. Check for any
