Test D: DTCs C1322, C1323 C1324 and C1325 - Brake Hydraulic Master Cylinder Piston-Travel Sensor(S) Faults

PINPOINT TEST D: DTCs C1322, C1323 C1324 AND C1325 - BRAKE HYDRAULIC MASTER CYLINDER PISTON-TRAVEL SENSOR(S) FAULTS

Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The ABS module sends voltage to the brake pedal travel sensor through circuit 3601 (WH/RD) and circuit 3603 (RD). The sensor is grounded through the ABS module on circuit 3600 (RD/WH) and circuit 1904 (GY/BK). The ABS module sends a reference signal to the brake pedal travel sensor on circuit 1905 (GY) and circuit 1820 (RD/YE).

Possible Causes
^ Circuit open
^ Circuit shorted
^ Brake pedal travel sensor
^ ABS module
