C006B Stability System Active Too Long

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

Set when the stability or traction control system has been intervening continuously for longer than the calibrated maximum. ESC and traction control are meant to act in short bursts; if the controller keeps modulating brakes or reducing torque beyond a time limit it concludes something is wrong, for example a persistently spinning wheel on ice, a dragging brake, a mismatched tyre or a sensor feeding a wrong signal, and stores this code while backing the intervention off to protect the hardware and avoid masking a real fault. The ABS/ESC warning lamp is set and base braking remains. Traction-control patents describe the controller overriding the driver's torque request only transiently to bring slip to target. The entry follows the SAE J2012 generic definition.

Likely causes

Wheel spinning or slipping for a long time
Dragging brake or mismatched tyre
Wrong sensor input driving the intervention

Symptoms

  • Stability/traction control cuts out
  • ABS/ESC warning lamp on
  • Prolonged intervention before fault
