Parking Brake Warning Switch: Testing and Inspection

Parking Brake Switch Test





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

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