C0081ABS Malfunction Indicator

  • Generic OBD-II code · Chassis
How the car detects it
Covers the ABS malfunction indicator (warning lamp) itself as driven or monitored by the ABS/ESC module. The module commands the ABS lamp on for a fault and off when healthy, and monitors the output circuit; this code is set when the lamp circuit is open or shorted, the lamp does not respond, or the commanded and observed states disagree, for example a bulb-check failure or a bus message not reaching the cluster. It is about the indicator path rather than the ABS hydraulics, so braking and ABS themselves may still work while the driver loses the warning. The related rear-axle mismatch and wheel-speed codes describe the faults the lamp would normally announce. No code-specific public bulletin was confirmed; the entry follows the SAE J2012 generic definition and warning-lamp output monitoring.
