L: C1730 - Reference Voltage Out of Range (+5 V)

Pinpoint Test L: DTC C1730 Reference Voltage Out Of Range (+5 V)

Normal Operation
The 5 volt reference voltage is supplied by the anti-lock brake system (ABS) module to the primary brake pressure transducer and the brake pedal travel sensor.

Reference voltage is supplied to the primary brake pressure transducer through circuit 3601 (WH/RD), and to the brake pedal travel sensor through circuit 3010 (TN). The reference voltage circuits return to the ABS module through circuit 3603 (RD) for the primary brake pressure transducer, and through circuit 3011 (BK/OG) for the brake pedal travel sensor.

Possible Causes
^ circuit 3601 (WH/RD) short to voltage, or short to ground
^ circuit 3010 (TN) short to voltage, or short to ground
^ ABS module
^ master cylinder.
^ primary brake pressure transducer
^ brake pedal travel sensor
