K: 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 drivers 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
