Parking Brake Switch Test

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If both the ABS/VSA indicator, the brake system indicator, and the trailer stability assist warning come on at the same time, check the VSA system first (see GENERAL TROUBLESHOOTING INFORMATION ).

Disconnect the parking brake switch connector (A) from the parking brake switch (B).

Check for continuity between the switch 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 the brake fluid level switch are OK, but the brake system indicator does not function, do the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).
Reconnect the parking brake switch connector.
