Gmc yukon has the abs & parking brake light

You have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

Any time abs and brake light come on you having brake failure.your brake fluid is low are leaking or the mastercylinder and abs unit faulty.not safe to drive vechicle.let dealership fix it.they have to use diagnostic equipment to find problem and fix it.

Its the electronic brake control module( it cost about 1100 ) at firestone if they get the part if you know anything about cars you could fix it for about 500 or so but it is tuff. check the ground first...miine is doing the same thing.. it means you have no abs but it won't hurt been driving around over 2 years and no problem, but you won't be able to pass inspection and when the weather is bad your will notice unless you get new tires and brakes check and cleaned....
