C0092 DTC: Traction Control Indicator Circuit High
OBD2 trouble code C0092 indicates that the ABS/TCS control module has detected a high voltage condition in the traction control indicator circuit. The module monitors the indicator signal and stores this code when the voltage is higher than the expected range.
What Does C0092 Mean?
The traction control indicator circuit provides communication between the ABS/TCS module and the instrument cluster. A high voltage signal may be caused by an open circuit, short to battery voltage, damaged wiring, or a faulty cluster input circuit.

Traction Control Indicator
Common Symptoms
- Traction Control warning lamp remains ON
- ABS or stability control warning message
- TCS operation may be disabled
- Indicator lamp stays active incorrectly
- Additional chassis codes may appear
Possible Causes
- Open circuit in indicator wiring
- Short to battery voltage
- Damaged connector terminals
- Faulty instrument cluster
- ABS/TCS module internal fault
- Charging voltage problems
Driving Risk Level
C0092 usually does not prevent normal driving, but traction control and stability systems may not function correctly. Loss of these safety systems can increase the chance of wheel spin during acceleration or reduced vehicle stability on slippery roads.
Drive carefully, especially in rain, snow, or loose surfaces. Repair the fault before relying on traction control assistance.
