C006C Stability System

Check engine lightUsually off

Drive cycleNot required
Limp modePossible

A general stability-system fault code covering the electronic stability control function as a whole rather than one named sensor or actuator. The ESC module sets it when an internal self-check fails, when the stability function cannot run because required inputs are missing or inconsistent, or when a system-level plausibility check is violated and no more specific code applies. It usually appears with companion codes that name the actual faulty sensor, valve or communication link. Stability control is disabled and the ABS/ESC warning lamp is set while base braking remains. Integrated-control sensor clusters and supervisory logic described in ESC patents coordinate yaw, lateral, steering and wheel-speed inputs; a break anywhere in that chain can set a system-level code. The entry follows the SAE J2012 generic definition.

Likely causes

Underlying sensor or actuator fault
Missing or inconsistent input data
