Test Procedure

  1. TO1 CHECK FOR SELF-TEST DTCS 
    • Ignition ON, engine OFF.

    Is DTC P0A50 present? 

    Yes No
    GO to  TO2. Unable to duplicate or identify the concern at this time.
    RETURN to SYMPTOM CHARTS for further direction.
  2. TO2 CHECK FOR CORRECT GENERATOR RPM 
    • Clear the SOBDMC DTCs.
    • Access the SOBDMC and monitor the G_SPEED (RPM) and RPM_TCM (RPM) PIDs.
    • Place gear selector lever in PARK.
    • Ignition ON, engine running.
    • Record the generator RPM at different engine speeds.
      Engine RPM Generator Motor RPM
      0 0
      800 2, 715
      1, 000 3, 394
      1, 200 4, 073
      1, 400 4, 752
      1, 600 5, 430
      1, 800 6, 109
      2, 000 6, 788

    Does the generator RPM correspond with the engine RPM in the table? 

    Yes No
    GO to  TO3. INSTALL a new Transmission assembly. REFER to the Automatic Transmission article.
    Clear the SOBDMC DTCs. REPEAT the self-test.
  3. TO3 CHECK THE GENERATOR RESOLVER CIRCUITS FOR AN OPEN 
    • Ignition OFF.
    • Transmission Assembly connector disconnected.
    • TCM-B connector disconnected.
    • Measure the resistance between:
      (+) Transmission Assembly Connector, Harness Side (-) TCM-B Connector, Harness Side
      GR1 - Pin 1 GR1 - Pin 8
      GR2 - Pin 2 GR2 - Pin 7
      GS1 - Pin 6 GS1 - Pin 20
      GS2 - Pin 5 GS2 - Pin 19
      GC1 - Pin 4 GC1 - Pin 14
      GC2 - Pin 3 GC2 - Pin 13

    Are the resistances less than 5 ohms? 

    Yes No
    GO to  TO4. REPAIR the open circuit. Clear the SOBDMC DTCs. REPEAT the self-test.
  4. TO4 CHECK THE GENERATOR RESOLVER CIRCUITS FOR A SHORT TO GROUND 
    • Measure the resistance between:
      (+) Transmission Assembly Connector, Harness Side (-)
      GR1 - Pin 1 Ground
      GR2 - Pin 2 Ground
      GS1 - Pin 6 Ground
      GS2 - Pin 5 Ground
      GC1 - Pin 4 Ground
      GC2 - Pin 3 Ground

    Are the resistances greater than 10K ohms? 

    Yes No
    GO to  TO5. REPAIR the short circuit. Clear the SOBDMC DTCs. REPEAT the self-test.
  5. TO5 CHECK THE GENERATOR RESOLVER CIRCUITS FOR A SHORT TO VOLTAGE 
    • Ignition ON, engine OFF.
    • Measure the voltage between:
      (+) Transmission Assembly Connector, Harness Side (-)
      GR1 - Pin 1 Ground
      GR2 - Pin 2 Ground
      GS1 - Pin 6 Ground
      GS2 - Pin 5 Ground
      GC1 - Pin 4 Ground
      GC2 - Pin 3 Ground

    Is any voltage present? 

    Yes No
    REPAIR the short circuit. Clear the SOBDMC DTCs. REPEAT the self-test. GO to  TO6.
  6. TO6 CHECK FOR DTCS 
    • Carry out the SOBDMC self-test.

    Is DTC P0C2F present? 

    Yes No
    GO to PINPOINT TEST TX . Unable to duplicate or identify the concern at this time.
    RETURN to SYMPTOM CHARTS for further direction.
