2002 Suburban 1500 - ABS Light On

My ABS light came on and when I turn off the engine, it sounds like an electric motor (loud humming) continues to run under the car. A local mechanic got under the Suburban, found the source of the noise and disconnected the electrical plug. The mechanic works at the local tire shop where I get my oil changed, tires rotated, etc. I'm uncomfortable with them working on my ABS. I still have brakes, but the ABS light stays on, as well as the Traction Control light now stays on as well.

Suggestions on what is wrong?

    I had the same problem on a 2001 Suburban. It was the ABS pump/module or whatever the heck they call it. It was running all the time even after the key was turned off. At the time the part was over $1200 at a dealer so I found one on ebay for $250 and had a shade tree mechanic install it. ( I tried it myself but there was one bolt I could not get too). It solved my problem except for the 'Traction Off" light. It is still illuminated all the time but there are no noticeable affects on performance.

    I would be careful when you are driving with the ABS unplugged. You no longer have that safety feature working for you and your brakes WILL lock if you have to stop very suddenly. Just a safety warning. Good luck.

No doubt the control module is out, and it continue to operate when the ignition key is off due to a circuit fault. You can disable it easily by pulling the 60 amp fuse in the under hood fuse box (it is listed on the panel as ABS). Note that this disables the ABS braking feature and traction control, so be very careful when driving. The part can be purchased on the GM global parts site, about $600-$700 for the module. This will be the second time this has gone out for me and GM is not sympathetic, rather "pathetic", for a part to fail so often.

    update, used the My Airbags rebuild site for the last repair, it went smooth and the module is still working after 5000 miles, so, so far so good

This is your brake control module that has gone out. You will have to go to the dealership to have this unit replaced. I had the same problem with my truck.

2002 chevy monte carlo ss 3.8liter -traction abs issues- the abs light and the traction control light come on and the display says to service traction control. how do i fix this and what could have caused...


So your problem right now is that the ABS/TRAC light keeps coming on? is this correct? and, is there any codes in the ABS Module?

There should be a history code in the ABS when that light comes on it has a code and it will store the code in the ABS computers history. Even if the light is off there should be an ABS code or codes in the history. Having that code or codes is where we need to go next.

Then, if the lights are coming on and it is NOT setting any codes. If thats the case there could be a power or ground problem to the ABS module.but the most problem I have seen with these is the wiring to the front sensors goes bad an intermitanlty will loose a front signal to one of the front sensors and cause this. But that would usually throw a code in it. 9 times out of 10 replacing the harnesses to both front sensors should do the trick (if we had a code and knew if it was RF or LF then we would just replace the wiring to the affected side).

Abs light came on while driving and when engine is shut off makes a loud humming sound ? took the fuse out to make hummimg noise go away and now abs light and emergency parking brake are on all the time...


have the abs module checked for codes to find out what the problem is.when the system detects a fault in the system it turns on the abs light and check the e-brake to make sure its all the way off.the humming noise sounds like its coming from the abs hydraulic unit that`s not shutting off.

01 Suburban with abs system. abs light came on


A relay controls the ABS motor. You can trace the wires running to it. The next time you shut the engine off unplug the relay. If that shuts it off get a new relay for the old one will not open its circuit to shut off the motor to the ABS motor

2002 Suburban ABS System Brake Light


I have had this same problem on two difference vehicles both of which are suburbans.

The solution is simple.
Remove the engine cover.
Locate a small ground wire that is bolted to the top rear of the engine block on the passenger side.
Remove the bolt, clean surfaces and replace.

This should solve your problem.

I know it seems too easy but it works.

Very loud Hum under driver side


There is an ABS fuse under the hood that you can take out, and the noise will quit. The noise is accually your ABS pump. They are kind of expensive.
