Pinpoint Test K: The Traction Control/Roll Stability Control System Cannot Be Disabled

CAUTION: Use the flex probe kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.

K1 CHECK THE STABILITY TRACTION CONTROL SWITCH
- Key in OFF position.
- Disconnect: Stability Traction Control Switch C280.
- Measure the resistance between the stability traction control switch C280-6, component side and C280-1, component side.
- Is the resistance greater than 10,000 ohms?
Yes : GO to K2.

No : INSTALL a new stability traction control switch. REFER to STABILITY/TRACTION CONTROL SWITCH . TEST the system for normal operation.
K2 CHECK CIRCUIT CCA15 (YE/GY) FOR A SHORT TO VOLTAGE
- Disconnect: ABS Module C155.
- Key in ON position.
- Measure the voltage between the ABS module C155-4, circuit CCA15 (YE/GY), harness side and ground.
- Is voltage present?
Yes : REPAIR circuit CCA15 (YE/GY) for a short to voltage. TEST the system for normal operation.

No : GO to K3.
K3 CHECK CIRCUIT CCA15 (YE/GY) FOR A SHORT TO GROUND
- Key in OFF position.
- 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 K4.

No : REPAIR circuit CCA15 (YE/GY) for a short to ground. TEST the system for normal operation.
K4 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.
- 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.
