Brake Fluid Level Switch Test

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If both the ABS/VSA indicator and the brake system indicator come on at the same time, check the VSA system for DTC's first (see ).

Disconnect the brake fluid level switch connector.
Check for continuity between the terminals (1) and (2) with the float in the down position and in the up position.
NOTE:
- Remove the brake fluid completely from the reservoir. With the float down, there should be continuity.
- Fill the reservoir with brake fluid to the MAX (upper) level (A). With the float up, 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 ).
