Test B: DTC B1483 - Brake Pedal Input Open Circuit

Pinpoint Test B: DTC B1483 - Brake Pedal Input Open Circuit

Normal Operation
Battery junction box (BJB) fuse 44 (15A) supplies fused battery voltage to the brake on/off (BOO) switch, along circuit CBP44DF (VT), with the ignition switch in the RUN/START position. With the brake pedal released, the BOO switch is closed and voltage is supplied to the ABS module from the switch along circuit CES09X (VT/OG). When the brake pedal is applied, the BOO switch opens and the voltage supply is interrupted.

Possible Causes
^ Fuse
^ Circuit open
^ BOO switch
