Remove brake fluid reservoir cap. Ensure brake fluid float moves up and down freely. If float does not move freely, replace brake fluid reservoir cap. If float moves freely, check for continuity between brake fluid level switch connector terminals. Continuity should exist with float down. Continuity should not exist with float up. If continuity does not exist as specified, replace brake fluid reservoir cap.
