Pinpoint Test D: DTC B1484 - Brake Pedal Input Open Circuit
Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
Fused battery voltage is sent to the brake pedal position (BPP) switch from battery junction box (BJB) fuse 14 (20A) along circuit 1119 (RD). When the brake pedal is pressed, the BPP switch closes and the voltage is then supplied to the ABS module along circuit 1651 (WH/RD). The ABS module is provided a ground along circuit 57 (BK).

This pinpoint test is intended to diagnose the following:
^ Fuse(s)
^ Wiring, terminals or connectors
^ BPP switch
