  1. K1 RETRIEVE AND RECORD ALL DTCS

    • Using the diagnostic scan tool, retrieve all DTCs.

    Are DTCs P0715, P0717, P0718 and/or P0720 present? 

    Yes  For DTCs P0715, P0717 and P0718, GO to  K2For DTCs P0715 and P0720, GO to  K6
    No  REFER to: Diagnosis By Symptom .

  2. K2 CHECK THE TSS (TURBINE SHAFT SPEED) SENSOR SIGNAL CIRCUIT FOR AN OPEN

    • Ignition OFF.
    • Disconnect Transmission Vehicle Harness C1520B .
    • Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
    • Measure:
