    • Key in OFF position.
    • Connect the scan tool.
    • Key in ON position.
    • Using the diagnostic tool, monitor the LCM traction control disable switch indicator PID.
    • Toggle the traction control disable switch once.
    • Does the traction control disable switch indicator status = ON?

    • Does the traction control disable switch indicator illuminate? 

    Yes  : GO to M5.

    No  : GO to  M6.

  5. M5 CHECK FOR CORRECT LCM OPERATION 
    • Disconnect all LCM connectors.
    • Check for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect all LCM connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 

    Yes  : INSTALL a new LCM. REFER to MULTIFUNCTION ELECTRONIC MODULES .

    No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.

  6. M6 CHECK TRACTION CONTROL DISABLE SWITCH CIRCUIT 57 (BK) FOR AN OPEN 
    • Disconnect: Traction Control Disable Switch C280.
    • Measure the resistance between ground and traction control disable switch C280-7, circuit 57 (BK), harness side.
    • Are the resistances greater than 5 ohms? 

    Yes  : GO to M7.

    No  : REPAIR circuit 57 (BK) for an open. CLEAR the DTCs. REPEAT the self-test,

  7. M7 CHECK CIRCUIT 961 (WH/PK) FOR AN OPEN 
    • Measure the resistance between traction control disable switch C280-4, circuit 961 (WH/PK), harness side and LCM C2145a-14, circuit 961 (WH/PK), harness-side.
    • Is the resistance less than 5 ohms? 

    Yes  : REPAIR circuit 961 (WH/PK) for an open. CLEAR the DTCs. REPEAT the self-test.

    No  : GO to M8.

  8. M8 CHECK THE TRACTION CONTROL DISABLE SWITCH CONNECTOR 
    • Connect: LCM C2145a.
    • Check the traction control disable switch connector for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect the traction control disable switch connector and make sure it seats correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 

    Yes  : INSTALL a new traction control disable switch.

    No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.

  9. M9 CHECK THE INSTRUMENT CLUSTER TRACTION CONTROL DISABLE SWITCH STATUS PID 
    • Using the diagnostic tool, monitor the instrument cluster traction control disable switch indicator PID.
    • Does the traction control disable switch indicator status = ON? 

    Yes  : INSTALL a new LCM. REFER to MULTIFUNCTION ELECTRONIC MODULES .

    No  : GO to M10.

  10. M10 CHECK TRACTION CONTROL DISABLE SWITCH CIRCUIT 57 (BK) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: Traction Control Disable Switch C280.
    • Measure the resistance between ground and traction control disable switch C280-2, circuit 57 (BK), harness side.
    • Are the resistances greater than 5 ohms? 

    Yes  : GO to M11.

    No  : REPAIR circuit 57 (BK) for an open. CLEAR the DTCs. REPEAT the self-test,

  11. M11 CHECK THE TRACTION CONTROL DISABLE SWITCH OPERATION 
    • Measure the resistance between traction control disable C280-1, component side, and traction control disable C280-2, component side, while pressing and releasing the traction control disable switch.
    • Is the resistance less than 5 ohms with the switch pressed and greater than 10,000 ohms with the switch released? 

    Yes  : GO to M12.

    No  : INSTALL a new traction control disable switch.

  12. M12 CHECK TRACTION CONTROL DISABLE SWITCH CIRCUIT 959 (GY) FOR AN OPEN 
    • Disconnect: ABS Module C135.
    • Measure the resistance between ABS Module C135-11, circuit 959 (GY), harness side and traction control disable switch C280-1, circuit 959 (GY), harness side.
    • Is resistance less than 5 ohms? 

    Yes  : INSTALL a known good ABS module. TEST the system for normal operation. If the traction control disable switch indicator operates correctly, GO to  M14. If not, GO to M13.
