ABS/Brake Light on GMC Envoy Dash

Recently my ABS (Antilock Brake System) and Brake light have came on the dash. I was parked at a store when it popped up out of no where. The brakes are working as they usually do so I was wondering if perhaps the Brake Fluid is needing to be flushed or changed, or would these lights come on due to pads needing replaced. My thinking is that it is something more internal than just pads with the system lights coming on.....could you help me so that I can resolve this problem "in house"

Might save you a whole lot of time if you stop by autozone, or Pep Boys, and get the free scan & see which sensor may be faulty, or sending code. I've had mine trip from driving in nasty weather for a while before, and a trip to the carwash, and concentrating the sensor areas with spray, (back of wheels area) put light back out, next start.

You need to have a scanner plugged into your computer and codes pulled. The ABS system has sensed a problem and will not work proper until the code is cleared. You will have standard brakes with no ABS at this time. You can take it to you local garage, a GM dealer or a big chain repair shop.

ABS LIGHT ON DASH?


Antilock Brake System, If its by it's self it means there is a fault. If accompanied by the regular red brake light normally means the problem is with the regular hydraulic part of the braking system. It also means your Antilock system has been defeated.

The amber ABS warning light is telling you that there is a problem with the ABS system. When the antilock brakes don't work you just have good old fashion non antilock brakes. When the red brake warning light is on it could be a couple of things. (unless you are talking about the brake light on the back of the car is stuck on) the red brake warning light on the dash tells you when the parking brake is on and it also tells you when there is a problem with the hydraulic system. Some cars will also turn this light on when the brake fluid is low, (not sure if the Cavalier does this)

The ABS system is computer controlled and needs to be scanned for trouble codes to diagnose the problem.

I can't say I have ever heard of a "brights" indicator flashing, Do the headlights go bright and dim as it is flashing? Is it a slow on and off like a turn signal or faster than that?

What do these icons mean 2996 gmc envoy


Do you mean 2006 GMC Envoy?
Top left- car with squiggly tire tracks and a wrench- that means something is wrong with your Stabilitrak (traction control) system. Top right- triangle around the car with squiggly tire tracks- this light comes on when the light on the top left comes on. It also means something is wrong with the Stabilitrak system. Bottom left- Antilock Brake System warning light- This means there is a fault in the antilock brake system. Considering that the stabilitrak control is part of the antilock brake system, it looks like there may be a common problem affecting both systems. You need to use a scan tool to access the chassis control system and read the diagnostic codes. There are definitely Diagnostic Trouble Codes stored when these lights are on. The code does not tell you what part to replace, but rather gives you a direction to go in diagnosing the cause of the problem.

Battery dash light flashing


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

I have just replacep brake pads on the rear but the light wont go out on the dash how do i turn it out


What light on the dash are you talking about? There is no light that comes on notifying you that you need to replace brake pads. If you are talking about the ABS light, that is something totally different and if your parking brake is on that probably signifys your parking brake is not totally released. If it's your ABS light, that is just telling you your antilock brakes are not working properly and is usually a dirty sensor or something.

Hope this helps
