Test D: DTCS C1322, C1323, C1324 and C1325 - Brake Hydraulic Master Cylinder Piston-Travel Sensor(S) Faults
Test D: DTCS C1322, C1323, C1324 and C1325 - Brake Hydraulic Master Cylinder Piston-Travel Sensor(s) FaultsNormal 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 1820 (RD/YE) open, short to ground or short to voltage
^ Circuit 1904 (GY/BK) open, short to ground or short to voltage
^ Circuit 1905 (GY) open, short to ground or short to voltage
^ Circuit 3600 (RD/WH) open, short to ground or short to voltage
^ Circuit 3601 (WH/RD) open, short to ground or short to voltage
^ Circuit 3603 (RD) open, short to ground or short to voltage
^ Brake pedal travel sensor
^ ABS module
