Brake Fluid Level Switch Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. 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 GENERAL TROUBLESHOOTING INFORMATION ).

Disconnect the brake fluid level switch connector.
Remove the reservoir cap (A). Check that the float (B) moves up and down freely; if it doesn't, replace the reservoir cap assembly.

Check for continuity between the terminals (1) and (2) with the float in the down position (C) and in the up position (D).
- With the float up, there should be no continuity.
- With the float down, there should be continuity.
NOTE: If the parking brake switch and the 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 ).
