C0085Traction Disable Indicator
- Generic OBD-II code · Chassis
- How the car detects it
- Covers the traction-disable indicator, the lamp that shows traction control has been switched off by the driver or by the system, as driven or monitored by the ABS/ESC module. The module lights this lamp when traction control is disabled and monitors the output; this code is set when the indicator circuit is open or shorted, the lamp does not respond, or commanded and observed states disagree. It concerns the indicator path, not the traction function; the driver may lose the on/off feedback while control itself behaves normally. It is closely tied to the traction-disable switch and the active-indicator lamp. Traction-control patents describe the driver being able to disable intervention, which this lamp announces. No code-specific public bulletin was confirmed; the entry follows the SAE J2012 generic definition.
