A: B1483 - Brake Pedal Input Open Circuit

Pinpoint Test A: DTC B1483 - Brake Pedal Input Open Circuit
Refer to Vehicle Diagrams Cell 42, Vehicle Dynamic Systems for schematic and connector information.

Normal Operation
Battery junction box (BJB) fuse 49 (15A) supplies fused battery voltage to the brake pedal position 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 anti-lock brake system (ABS) module from the switch along circuit CES09 (VT/OG). When the brake pedal is applied, the switch opens and the voltage supply is interrupted.

Possible Causes
^ Fuse
^ Circuit open
^ Brake pedal position switch
^ ABS module
