Brake Controller Only Works with Manual Override on a 2002 Chevrolet Tahoe
Question:
It was working then it quit. Is there a fuse some where I can check. Works with the controller arm but not the brake pedal
asked by: Larry S
Expert Reply:
The fuse that you will want to check is labeled "CHMSL" and can be found in the fuse box located in the engine bay. I have attached a photo of this for you. If the fuse is still good, then you will want to begin checking the the brake signal wire (usually red) coming from the brake controller ran to the cold side of the brake pedal. It is likely that this wire has become either pinched or broken. If you cannot find a loose connection, then you may just want to run a new wire from the controller to the pedal.
If you need a circuit tester, I like the # PTW2993.
