Bad ABS Module?
Anybody know the symptoms of a bad ABS Module?
I have a 2008 Suburban with traction control problems and Anti-lock brakes activating on light turns and even on straight no turn driving.
Any clue?
no codes on computer and the traction lock light flashes 3 times then gone. Totally confused and mechanics cannot find problem.
I did replace both front wheel hubs complete with sensors.

d450heavy,
I am sorry you are having this concern. I know it can be frustrating when the concern can not be duplicated. I will try to keep an eye out for any information that may be helpful to you. If you would like me to speak with your GM dealership, let me know.

Get a better mechanic. It should not be hard to find. Someone need to drive the truck while watching live ABS data in a scan tool. Its either got a failing wheel speed sensor/ bearing or the wire going to the wss is bad. GM has a problem with the pigtails at the speed sensors the wire breaks in the jacket causing exactly what you describe.

I just replaced my rear shocks and had an issue with the traction control and ABS light coming on, it was because I knocked a wheel speed sensor connector loose.
I would suggest disconnecting and reconnecting all 4 speed sensors and inspect them as best you can for any contamination or poor connection.
