Brake Fluid Level Switch Test

Disconnect the brake fluid level switch connector.
Check for continuity between the terminals (1) and (2) with the float in the down position and in the up position.
NOTE:
- If both the ABS indicator and the brake system indicator come on at the same time, check the ABS or VSA system first: ABS (see GENERAL TROUBLESHOOTING INFORMATION ), For 2009-11 VSA (see GENERAL TROUBLESHOOTING INFORMATION ), or for 2012 VSA (see GENERAL TROUBLESHOOTING INFORMATION).
- 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 parking brake switch and brake fluid level switch are OK, but the brake system indicator does not function, do the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ).
