Brake Light Warning On

Check to see if parking brake is applied and release if necessary. There could be a partial failure in brake hydraulic circuit. To verify, check for excessive brake pedal travel, excessive pedal force required to stop, excessive stopping distances, or early wheel lock-up tendency. Repair as needed.

Accumulator pressure may be low. Check for an electrical failure in the ignition circuit, blown 30A fuse, defective pressure switch at "A" and "C" terminals, or faulty connectors and wiring. Check for low fluid in reservoir. Check for faulty warning light pressure switch and replace if needed.
