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 same time, check the ABS or VSA first: ABS, VSA.
  • If the parking brake switch and fluid level switch are OK, but brake system indicator does not function, check the ABS or VSA: ABS, VSA.
