Parking Brake Warning Switch: Testing and Inspection

Parking Brake Switch Test





1. Disconnect the parking brake switch connector (A) from the switch (B).
2. Check for continuity between the positive terminal (C) and body ground.
^ With the parking brake pedal pressed, there should be continuity.
^ With the parking brake pedal released, there should be no continuity.

NOTE:
^ If both the ABS indicator and the brake system indicator come on at the same time, check the ABS first.
^ If the parking brake switch/fluid level switch is OK, but the brake system indicator does not function, check the ABS (For Canada model: do the input test for the daytime running lights control unit first).
