It is important to know what to look for when diagnosing the cause of one or both of these lights illuminating on your vehicle.

Usually, the brake fluid level sensor and the parking brake are the only two items that can activate the brake light. The brake light on most vehicles is activated by a simple circuit involving only one or two components. When this light is on, there are often trouble codes stored to help the owner or a technician diagnose the source of the fault in the anti-lock braking system. The ABS light differs from the BRAKE light as it is usually controlled by a computer module. However, on some vehicles, it can simply indicate a problem elsewhere in the system and can be illuminated immediately if there is an ABS fault.
