Pinpoint Test H: Traction Control Cannot Be Disabled

NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
  1. H1 CHECK THE STABILITY/TRACTION CONTROL SWITCH 
    • Ignition OFF.
    • Disconnect: Stability/Traction Control Switch C280.
    • Measure the resistance between the stability/traction control switch C280-6, component side and C280-2, 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? 
  2. H2 CHECK CIRCUIT CCA15 (YE/GY) FOR AN OPEN 
    • Disconnect: ABS Module C155.
    • Measure the resistance between the ABS module 0155-4, circuit CCA15 (YE/GY), harness side and stability/traction control switch C280-6, circuit CCA15 (YE/GY), harness side.

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to H3  .
    • No:  REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
  3. H3 CHECK CIRCUIT CCA15 (YE/GY) FOR A SHORT TO GROUND 
    • Measure the resistance between the ABS module C155-4, circuit CCA15 (YE/GY), harness side and ground.

    • Is the resistance greater than 10,000 ohms? 
    • Yes:  GO to H4  .
    • No:  REPAIR circuit CCA15 (YE/GY). TEST the system for normal operation.
  4. H4 CHECK CIRCUIT GD114 (BK/BU) FOR AN OPEN 
    • Measure the resistance between the stability/traction control switch C280-2, circuit GD114 (BK/BU), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to H5  .
    • No:  REPAIR circuit GD114 (BK/BU). TEST the system for normal operation.
  5. H5 CHECK FOR CORRECT ABS MODULE OPERATION 
    • Disconnect all the ABS connectors.
    • Check for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect all the ABS 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 ABS module. REFER to ANTI-LOCK BRAKE SYSTEM (ABS) MODULE . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
