Test P: DTC C1288 - Pressure Transducer Main/Primary Input Circuit Failure

PINPOINT TEST P: DTC C1288 - PRESSURE TRANSDUCER MAIN/PRIMARY INPUT CIRCUIT FAILURE

Normal Operation
The brake pedal pressure transducer is integral to the hydraulic control unit (HCU). The transducer sends a signal to the anti-lock system (ABS) module once a predetermined pressure in the brake system is reached. This signal is checked against other inputs and if it does not agree with those inputs, diagnostic trouble code (DTC) C1288 is set. If a new transducer needs to be installed, then a new HCU must be installed. If the transducer is open, shorted to ground or shorted to voltage, DTC C1288 will be set.

Possible Causes
^ HCU
^ ABS module
