Brake Warning Indicator: Testing and Inspection

If the parking brake light is included in the service brake warning light system, the brake warning light will flash only when the parking brake is applied with the ignition ON. The same light will also glow, if one of the two service brake systems fails when the brake pedal is applied.

To test the system, turn the ignition ON and apply the parking brake. If the lamp fails to light, inspect for a burned out bulb, disconnected socket, or broken or disconnected wire at the switch.

To test the brake warning system, raise the car and open a wheel bleeder valve while a helper depresses the brake pedal and observes the warning light on the instrument panel. If the bulb fails to light, inspect for a burned out bulb, disconnected socket, or a broken or disconnected wire at the switch. If the bulb is not burned out, and the wire continuity is proven, replace the brake warning switch.
