Pinpoint Test BG: The Traction Control System Cannot Be Disabled Using The Traction Control Switch

NOTE: This test requires the use of at least 2 keys programmed to the vehicle, one admin key and one restricted key.
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  1. BG1: CHECK THE ABS MODULE FOR DTCS 
    • Ignition ON, engine OFF.
    • Carry out the ABS self-test.
    • Is DTC C1109:64 present in the ABS module? 
    Yes No
    Go to  BG8. Go to  BG2.
  2. BG2: VERIFY THE IGNITION KEY IN USE IS NOT RESTRICTED 
    • For vehicles equipped with a keyless vehicle system,
      • 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 No
    The current ignition key is a restricted key and is operating correctly.
    Go to  BG3.    		 REPEAT the test steps using different ignition keys until the message center DOES NOT display MYKEY ACTIVE DRIVE SAFELY.
    Go to  BG3.
  3. BG3: VERIFY THE MYKEY TRACTION CONTROL SETTING 
    • Using the message center, verify the MyKey traction control setting. Refer to the Owner's Literature for instructions on setting the MyKey functions.
    • Is the MyKey traction control setting configured to always on? 
    Yes No
    Go to  BG4. Go to  BG8.
  4. BG4: VERIFY TRACTION CONTROL FUNCTION CAN BE DISABLED USING THE ADMIN KEY 
    • Using the message center, verify traction control can be enabled and disabled using the admin 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 key? 
    Yes No
    The system is operating correctly at this time. The concern may have been caused by the use of a restricted key. INFORM the customer the traction control can only be disabled using an admin key when the MyKey traction control setting is configured to always on. Go to  BG8.
  5. BG5: CHECK FOR ABS MODULE DTCS 
    • Carry out the ABS self-test.
    • Are any DTCs present? 
    Yes No
    REFER to the ABS - ANTILOCK BRAKING SYSTEM DTC INDEX  Go to  BG6.
  6. BG6: CHECK FOR GWM DTCS 
    • Carry out the GWM self-test.

  8. BG8: CHECK THE LIN CIRCUIT FOR A SHORT TO GROUND 
    • Ignition ON, engine OFF.
    • ABS Module connector disconnected.
    • HVAC_B Module connector disconnected.
    • Measure the resistance between:
      (+) ABS Module Connector, Harness Side (-)
      TCS Ground
    • Is the resistance greater than 10, 000 ohms? 
    Yes No
    Go to  BG9. REPAIR the circuit.
  9. BG9: CHECK THE LIN CIRCUIT FOR AN OPEN 
    • Measure the resistance between:
      (+) ABS Module Connector, Harness Side (-) HVAC_B Module Connector, Harness Side
      TCS TCS
    • Is the resistance less than 3 ohms? 
    Yes No
    Go to  BG10. REPAIR the circuit.
  10. BG10: VERIFY ALL WIRING CONNECTIONS 
    • Using a good light source, inspect all disconnected electrical connectors for the following:

  11. BG11: CHECK FOR CORRECT HVAC MODULE OPERATION 
    • Ignition OFF.
    • ABS Module connector connected. Make sure the connector seats and latches correctly.
    • HVAC_B Module connector connected. Make sure the connector seats and latches correctly.
    • Operate the system and determine if the concern is still present.
    • Is the concern still present? 
    Yes No
    INSTALL a new HVAC module.
    CHECK OASIS for any service articles: TSB, GSB, SSM or FSA.
