One problem related to adaptive equipment has been reported for the 2004 GMC Sierra. The most recently reported issues are listed below.
I have a 2004 GMC Sierra that has an electrical issue with the abs or brake system. The brake light, abs light and service brake system light goes off at random times. Might have something to do with the air conditioning because the a/c draws power from the battery and I can see that a certain level the indicators go off. Most of the time the lights chime and blink when I apply the brake but it also has happened when just turned the truck on. I've replaced the rotors and pads to still have the problem. I'm not sure if it's a ground or sensor that is failing. I've found TSB for regrounding, failing sensors, or ecbm. Still haven't found the correct diagnosis. I just hope the abs functions when I need it.
