Red Brake Warning Lamp Indicator
TEST DESCRIPTION
The red brake warning light is constantly monitored by the Rear Anti-lock Electronic Control Module. If the red light illuminates, the anti-lock electronic control module will disable the Rear Anti-lock Brake (RABS II ) system. For this reason, diagnosing and resolving any base brake concerns illuminating the red brake warning light will, in most cases, resolve a perceived RABS II concern.
BRAKE LIGHT SELF-CHECK
The red brake warning light is used to indicate a low brake fluid level condition or parking brake applied condition. To check this light, insert the key in the ignition lock cylinder and turn it to the START position. The brake warning light should glow in this position. If it fails to glow, service the electrical system as required. Go to System Pre-Check Test B. [1][2]B
Allow the key to spring back from the START position to the RUN position. At this time the red brake warning light should turn off. If it does not turn off, recheck the parking brake switch to make sure that it is fully disengaged. If the red brake warning light is still on, service the base brake system. In the event that the red brake warning light remains on, go to System Pre-Check Test E , Red Brake Light ON. [1][2]E
