Pinpoint Test O: The Traction Control System Is Inoperative Or Cannot Be Disabled Using The Traction Control Switch

  1. Refer to Instrument Cluster for schematic and connector information.

    Normal Operation and Fault Conditions 

    The traction control switch is used to switch the traction control system on or off. When the traction control switch is pressed, the IPC receives a ground signal from the switch and illuminates the stability-traction control OFF indicator. The IPC sends a traction control switch message to the GWM over the HS-CAN3 and the GWM relays this message to the ABS module over the FD-CAN. The ABS module takes the necessary action depending on the switch inputs and traction control message.

    REFER to: Anti-Lock Brake System (ABS) and Stability Control - Diesel/Flex Fuel - Ethanol/Full Hybrid Electric Vehicle (FHEV)/Gasoline - System Operation and Component Description .

    Possible Causes 

    • A MyKey restricted key is in use
    • Network communication concern
    • Traction control switch
    • IPC

    NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

  2. O1 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE FOR DTCS

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the ABS module self-test.

    Is DTC C1109:24, U0138:xx or U0155:xx present in the ABS module? 

    Yes  If DTC U0155:00 is present: 
    GO to Pinpoint Test AP
    If DTC U0138:xx is present: 
    GO to Pinpoint Test AV
    If DTC C1109:24 is present:  GO to  O6
    No  GO to  O2

  3. O2 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) FOR DTCS

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the IPC self-test.

    Are there any DTCs in the IPC ' 

    Yes  DIAGNOSE all IPC DTC s. REFER to: Instrumentation, Message Center and Warning Chimes .
    No  If the IPC cannot communicate with the diagnostic scan tool, REFER to: Controller Area Network (CAN) Module Communications Network - Electric . If there are no DTCs in the IPC GO to  O3

  4. O3 VERIFY THE IGNITION KEY IN USE IS THE ADMIN IGNITION KEY

      • Place 1 of the passive keys inside the vehicle and all other passive keys at least 1 meter (3 feet) away from the vehicle.
      • Press the start-stop button without pressing the brake pedal.

    • For vehicles not equipped with a keyless vehicle system, turn the ignition to the ON position.

    • Monitor the message center.

    Does the message center display MYKEY ACTIVE DRIVE SAFELY? 

    Yes  REPEAT the test steps using different ignition keys until the message center DOES NOT display MYKEY ACTIVE DRIVE SAFELY. GO to  O4
    No  The current ignition key is a restricted key and is operating correctly. GO to  O4

    Is the MyKey traction control setting configured to always on? 

    Yes  GO to  O5
    No  GO to  O6

  6. O5 VERIFY TRACTION CONTROL FUNCTION CAN BE DISABLED USING THE ADMIN IGNITION KEY

    • Using the message center, verify traction control can be enabled and disabled using the admin ignition key.

      • Refer to the Owner's Literature for instructions on enabling and disabling traction control.

    Can traction control be enabled and disabled using the admin ignition key? 

    Yes  GO to  O6
    No  Diagnose all IPCDTC s. REFER to: Instrumentation, Message Center and Warning Chimes .

  7. O6 CHECK THE TRACTION CONTROL SWITCH

    • Ignition OFF.

    • Disconnect Instrument Panel Center Stack Middle Switch connector C2039.

    • Disconnect Instrument Panel Center Stack Right Switch connector C2304.

    • While pressing and releasing the switch:

    • For vehicles with base trim option, measure:
      Positive Lead Measurement / Action Negative Lead

      		 C2304 Pin 3
      Component side 

    Is the resistance less than 3 ohms with the switch pressed and greater than 10, 000 ohms with the switch released? 

    Yes  GO to  O7
    No  INSTALL a new center stack switch assembly. REFER to: Stability Assist/Traction Control Switch .

  8. O7 CHECK THE TRACTION CONTROL SWITCH GROUND CIRCUIT FOR AN OPEN

    • Ignition OFF.
