Customer Question
ABS, Traction Control lights...

ABS, Traction Control lights are on all the time as soon as you turn the key on

Mechanic's Assistant: Is it just the ABS light? Or is the brake system warning light on, too?

It has two lights the traction controll and the abs. Display says service traction control, stability and steering

Mechanic's Assistant: What is the model/year of your GMC?

2007 buick lacrosse

Mechanic's Assistant: Are you fixing your LaCrosse yourself? What have you tried so far?

Was attempting to. I have ohmed out the wheel sensors and they all appear to be good. checked for power and return on the harnesses and appear to be good. Hooked up a scan tool that is supposed to read ABS codes but get link error every time. Have replaced the ABS module

Hello, my name is***** will be helping you out! I have over thirteen years of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

If the ABS & Traction light is on and your scanner will not communicate, it is likely the ABS module itself has failed on you (EBTCM) Do you have any other issues besides that?
