Parking Brake Warning Switch: Testing and Inspection

Parking Brake Switch Test

NOTE: If the ABS indicator, the AHB indicator, and the brake system indicator come on at the same time, check the advanced hydraulic booster system first, then check the ABS.

1. Remove the center console.
2. Disconnect the parking brake switch connector (A) from the parking brake switch (B).





3. Check for continuity between the switch terminal (C) and body ground.

^ With the parking brake lever pulled, there should be continuity.
^ With the parking brake lever released, there should be no continuity.

NOTE: If the parking brake switch and the fluid level switches are OK, but the brake system indicator does not function, do the gauge control module self-diagnostic function.

4. Reinstall the center console.
