2. Check for continuity between the positive terminal (C) and body ground.

With the parking brake pedal pushed, there should be continuity.

With the parking brake pedal released, there should be no continuity.

BRAKE FLUID LEVEL SWITCH TEST

Check for continuity between the terminals (1) 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.

NOTE:

If both the ABS/VSA indicator and the brake system indicator come on at the
same time, check the VSA system first (see ABS/VSA INDICATOR ).

NOTE:

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 switch is OK, but the brake
system indicator does not function, check the VSA (Do the input
test for the daytime running lights control unit first).
