Test B: DTC B1483 - Brake Pedal Input Circuit Failure

Pinpoint Test B: DTC B1483 - Brake Pedal Input Circuit Failure
Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
The ABS module receives brake pedal input from the PCM over the high-speed controller area network (HS-CAN) bus. The ABS module compares this information against other inputs (wheel speed signals, vehicle speed signal, brake pressure transducer) to determine if the brake pedal input is valid.

^ DTC B1483 Brake Pedal Input Circuit Failure - If, during normal operation or the on-demand self test, the ABS module cannot detect the brake pedal input or if the brake pedal input does not match information from other sensors (wheel speed signals, vehicle speed signal, brake pressure transducer), DTC B1483 will be set.

This pinpoint test is intended to diagnose the following:
^ Wiring, terminals or connectors
^ Brake pedal switch
