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 both the ABS/VSA indicator, and the brake system indicator come on at the same time,
check the VSA first.
If the parking brake switch/fluid level switches are OK, but the brake system indicator does not function,
check the VSA.
