Test A: DTC B1483 - Brake Pedal Input Open Circuit

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

Normal Operation
Battery junction box (BJB) fuse 49 (15A) supplies fused ignition voltage to the brake pedal position (BPP) switch, along circuit CBP49 (VT/GY), with the ignition switch in the RUN/START position. With the brake pedal released, the switch is closed and voltage is supplied to the ABS module along circuit CES09 (VT/OG). When the brake pedal is applied, the switch opens and the voltage supply is interrupted.
^ DTC B1483 Brake Pedal Input Open Circuit - If during normal operation or the on-demand self test, the ABS module detects an open circuit on the BPP switch circuit, DTC B1483 will be set.

This pinpoint test is intended to diagnose the following:
^ Fuse
^ Wiring, terminals or connectors
^ BPP switch
^ ABS module
