Pinpoint Test C : Shift Solenoid C

  1. C1 RETRIEVE AND RECORD ALL DTCS

    • Using the diagnostic scan tool, retrieve all DTCs.

    Are DTCs P0760, P0763, P0764, P0979 and/or P0980 present? 

    Yes  For DTCs P0760, P0763 and/or P0764, GO to  C2. For DTC P0979, GO to  C4. For DTC P0980, GO to  C6.
    No  GO to Symptom Chart .

  2. C2 CHECK THE SSC CIRCUIT FOR AN OPEN

    • Ignition OFF.
    • Disconnect: Transmission Vehicle Harness C168 .
    • Disconnect: PCM C175T .
    • Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
    • Measure the resistance  between.
