C1213 - FAULT CODE - OBD2

C1213 FORD, MERCURY, LINCOLN: ABS FRONT RIGHT DUMP VALVE CIRCUIT SHORTED TO THE GROUND

The ABS (Anti-lock Brake System) is responsible for preventing one of the wheels from locking during brake application. To perform this action, the system has several sensors that are installed on the wheels, and it is through the information provided by these that the speed of the wheels is checked.

The ABS module determines whether conditions exist that could cause a lockup. To do this, it compares the speeds based on the information it receives from the speed sensors. If there is a risk of lock-up, the ABS is activated and the brake pressure is automatically reduced in order to bring the deficient wheel to a level that allows it to function properly.

The ABS module continuously checks the ABS front right dump valve. If an erratic operation caused by a short to ground is discovered, the DTC C1213 OBDII code will be stored.

• Check Engine lamp illumination.
• Anti-Lock Brake System fault warning light illuminated.
