Code C1324 Description

The Anti-Lock Brake System (ABS) module sends voltage to the brake pedal travel sensor. The sensor is grounded through the ABS module and then the ABS module sends a reference signal to the brake pedal travel sensor. The Anti-Lock Brake System (ABS) Module monitors the Brake Hydraulic Master Cylinder Piston Travel Sensor. The ABS Module sets the OBDII code when the Brake Hydraulic Master Cylinder Piston Travel Sensor is not to factory specifications.
