Warning Light Switch
- Attach a bleeder hose to bleeder screw at either rear brake. Immerse other end of hose in container with brake fluid. Turn ignition on. Open bleeder screw while pressure is being applied to brake pedal. Warning light should activate. Close bleeder screw before pressure is released from pedal.
- Re-apply brake pedal using moderate to heavy pressure. Light should go out. Repeat test on front brake system. System should function in same manner. Turn ignition off.
- If light does not activate on either system, but does operate when electrical circuit is tested, the warning light switch portion of valve is defective.
