I’ve been dealing with a parking brake light always on. We changed all my sensors and re soldered the wiring harness at the instrument cluster. I follow the wire all the way to the parking brake sensor and still cant find where the problem could be.
Parking brake light always on
You the provided wiring diagram to help diagnose your problem area.
*NOTE – the brake light will also illuminate when the brake fluid level is low or brake fluid level sensor is sticking. It will also illuminate if the park brake is not released completely. Sometimes this requires lifting up a bit on the park brake.
