Pinpoint Test K: DTC C1093 - Traction Control Disable Switch Circuit Failure/The Traction Control Is Inoperative
- K1 CHECK CIRCUIT 1412 (WH/PK) FOR A SHORT TO GROUND
- Disconnect: Traction Control Switch C2114.
- Disconnect: Instrument Cluster C220a.
- Key in OFF position.
- Measure the resistance between traction control switch C2114-10, circuit 1412 (WH/PK), harness side and ground.
- Is the resistance greater than 10,000 ohms?
Yes : GO to K2.
No : REPAIR circuit 1412 (WH/PK) for an open. TEST the system for normal operation.
- K2 CHECK THE STABILITY ASSIST SWITCH
- Connect: Traction Control Switch C2114.
- Make sure the traction control switch is not pressed (stability assist not disabled).
- Measure the resistance between instrument cluster C220a-5, circuit 1412 (WH/PK), component side and ground.
- Is the resistance greater than 10,000 ohms?
Yes : GO to K3.
No : INSTALL a new traction control switch. TEST the system for normal operation.
- K3 MONITOR THE INSTRUMENT CLUSTER PID
- Connect: Instrument Cluster C220a.
- Connect the scan tool.
- Key in ON position.
- Enter the following diagnostic mode on the scan tool: Instrument Cluster Traction Control/IVD Status PID.
- Monitor the instrument cluster traction control/IVD status PID while pressing the traction control/interactive vehicle dynamics (IVD) disable switch repeatedly.
- Does the PID agree with the switch position?
Yes : GO to K4.
No : GO to K5.
- K4 CHECK FOR CORRECT ABS MODULE OPERATION
- Disconnect the ABS connector.
- Check for:
- corrosion.
- pushed-out pins.
- Connect the ABS connector and make sure it seats 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 in this article. 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.
- K5 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Disconnect all instrument cluster connectors.
- Check for:
- corrosion.
- pushed-out pins.
- Connect all instrument cluster 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 instrument cluster. REFER to INSTRUMENT CLUSTER . 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.
