Pinpoint Test T: The Traction Control System Cannot Be Disabled/Enabled Or The Traction Control System Is Inoperative

WARNING: This page is about a different variant/trim than selected.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. T1 VERIFY PCM CONFIGURATION 
    • Connect the scan tool.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Module Re-programming - PCM.
    • Test drive the vehicle and verify that the concern is still present.
    • Is the concern still present? 
    1. Yes  : GO to T2.
    2. No  : The system is operating correctly at this time. The concern may have been caused by a incorrectly configured PCM.
  2. T2 VERIFY IPC CONFIGURATION 
    • Connect the scan tool.
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Programmable Module Installation (PMI) - IPC.
    • Configure the IPC using as-built data. Refer to Programmable Module Installation (PMI) Using the Integrated Diagnostic System (IDS) When the Original Module is Not Available in MODULE CONFIGURATION .
    • Test drive the vehicle and verify that the concern is still present.
    • Is the concern still present? 
    1. Yes  : GO to T3.
    2. No  : The system is operating correctly at this time. The concern may have been caused by a incorrectly configured IPC.
  3. T3 CHECK FOR DTCs 
    • Check for any ABS module, IPC or PCM DTCs.
    • Are any DTCs present? 
    1. Yes  : For ABS module DTCs, REFER to the ABS Module DTC Chart .

      For PCM DTCs, REFER to the INTRODUCTION - GASOLINE MODELS .

      For IPC DTCs, REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES .

    2. No  : GO to T4.
  4. T4 CHECK THE TRACTION CONTROL SWITCH 
    • Disconnect: Traction Control Switch C280.
    • Measure the resistance between traction control switch C280 pin-1, component side, and traction control switch C280 pin-6, component side while pressing and releasing the switch.
    • Is the resistance greater than 10, 000 ohms with the switch released and less than 5 ohms with the switch pressed? 
    1. Yes  : GO to T5.
    2. No  : INSTALL a new traction control switch. TEST the system for normal operation.
  5. T5 CHECK THE TRACTION CONTROL SWITCH SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: IPCC220.
    • Ignition ON.
    • Measure the voltage between traction control switch C280-6, circuit CCA15 (YE/GY), harness side and ground.

    • Is any voltage present? 
    1. Yes  : REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
    2. No  : GO to T6.
  6. T6 CHECK THE TRACTION CONTROL SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure the resistance between traction control switch C280-6, circuit CCA15 (YE/GY), harness side and ground.

    • Is the resistance greater than 10, 000 ohms? 
    1. Yes  : GO to T7.
    2. No  : REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
  7. T7 CHECK THE TRACTION CONTROL SWITCH GROUND CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Measure the resistance between traction control switch C280-1, circuit GD114 (BK/BU), harness side and ground.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to T8.
    2. No  : REPAIR circuit GD114 (BK/BU). TEST the system for normal operation.
  8. T8 CHECK TRACTION CONTROL SWITCH SIGNAL CIRCUIT FOR AN OPEN 
    • Measure the resistance between IPCC220-13, circuit CCA15 (YE/GY), harness side and traction control switch C280-1, circuit CCA15 (YE/GY), harness side.

    • Is the resistance less than 5 ohms? 
    1. Yes  : GO to T9.
    2. No  : REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
  9. T9 CHECK FOR CORRECT IPC OPERATION 
    • Ignition OFF.
    • Check IPCC220 for:
      • corrosion.
      • pushed-out pins.
      • spread terminal.
    • Connect: IPCC220.
    • Make sure the connector is seated correctly then operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. Yes  : INSTALL a new IPC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . TEST the system for normal operation.
    2. No  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
