1. Disconnect the connector (A).

2. Check for continuity between the brake fluid level switch connector terminals No. 1 and No. 2 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 (B). With the float up, there should be no continuity.

NOTE: If the brake fluid level switch is OK, but the brake system indicator (red) does not function, do the gauge control module self-diagnostic function .

3. Connect the connector.
