Parking Brake Warning Switch: Testing and Inspection

Parking Brake Switch Test

NOTE: If both the ABS/VSA indicator and the brake system indicator come on at the same time, check the VSA system first.

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).
