C004FABS Control Module Over Temperature

  • Generic OBD-II code · Chassis
  • Can trigger limp mode
How the car detects it
Set when the ABS/ESC control module or its integrated pump motor reaches a temperature above the safe operating limit. Repeated or prolonged pressure modulation, for example during long downhill ABS use, frequent stability interventions or an electrical fault that keeps the pump running, heats the hydraulic unit and its motor; the module monitors an internal temperature model or sensor and stores this code to protect the hardware. It temporarily disables ABS, traction and stability control until the unit cools, then restores them. A persistent over-temperature points to a seized pump, a stuck valve causing continuous pumping or a control fault. Base braking remains and the ABS warning lamp is set while the function is suspended. The entry follows the SAE J2012 generic definition and ABS hydraulic unit thermal protection.
