Have a 07 Tahoe with the abs, traction control and brake lights on. Stability off message as well. Ran the ABS code and got C0110-00. Checked and cleaned grounds. Checked ABS module connector for power on two pins and ground on two. Checked out. Possibly bad ABS pump?

Did you use a contact cleaner/lubricant in connectors? Not only clean it's connector but follow the ground back to it's chassis connection and clean it also before replacing parts.

I did not use a cleaner/lubricant on the connectors to the ABS module. I did follow the ground back to the chassis connection and cleaned it with a wire brush and some brake cleaner. I'll give the cleaner a shot. I read somewhere that the ABS pump could be bad so I have been researchilng how to test the pump. It seems like the only way to do that is to have one of those expensive diagnostic tools to do this.

Thanks for the reply by the way!
