If the specification was not obtained:
- Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).
- If necessary, repair the faulty wiring connection.
If no malfunction was found in the wiring and the resistance was not OK:
- Replace the Multi-Function Transmission Range (TR) Switch F125.
If no malfunction is found in the wiring and the resistance was OK:
- Replace the Transmission Control Module (TCM) J217. Refer to Transmission Control Module J217, Replacing .
- Erase the DTC memory. Refer to DIAGNOSTIC MODE 04: RESET/DELETE DIAGNOSTIC DATA .
- Perform a road test to verify repair.
If the DTC does not return:
Repair complete, Generate readiness code. Refer to READINESS CODE, GENERATING .
- End diagnosis.
