Brake Fluid Level Sensor/Switch: Testing and Inspection
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.
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.
^
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.
^
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.
