Question about 2002 Chevrolet Suburban 2500
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?
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.

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.
