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. Initial Inspection and Diagnostic Overview

1. Disconnect the parking brake switch 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 pressed, there should be continuity.

- With the parking brake pedal released, there should be no continuity.

NOTE: If the parking brake switch and fluid level switch are OK, but the brake system indicator does not function, check the VSA system. Initial Inspection and Diagnostic Overview
