Brake Fluid Level Switch Test

Check for continuity between the terminals (1) and (2) with the float in the down position and in the up position.

• 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.
• If both the ABS/VSA indicator and the brake system indicator come on at the same time, check the VSA system first (see GENERAL TROUBLESHOOTING INFORMATION ).
• 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 test (see SELF-DIAGNOSTIC FUNCTION ).
