Test K: DTC C1288 - Brake Pressure Transducer Input Circuit Failure

Pinpoint Test K: DTC C1288 - Brake Pressure Transducer Input Circuit Failure

Normal Operation
The brake pressure transducer sends current to the anti-lock brake system (ABS) module proportional to the driver's brake pedal application.

Reference voltage is supplied by circuit 7-CF64 (YE/BK). Ground is provided through circuit 9-CF64 (BN/YE). The transducer current is supplied by circuit 8-CF64 (WH/BK).

Possible Causes
^ Reference voltage circuit 7-CF64 (YE/BK) open, short to ground, or short to voltage
^ Ground circuit 9-CF64 (BN/YE) open, short to ground, or short to voltage
^ Transducer signal circuit 8-CF64 (WH/BK) open, short to ground, or short to voltage
^ Brake pressure transducer
^ ABS module
