TRACTION CONTROL ACTIVATES ON DRY GROND FROM TAKE OFF

2005 Chevrolet Avalanche • 145 miles

Have a 2005 4wd Avalanche and I hear my ABS pump kick in for a few seconds when I take off from a dead stop. The pavement is dry and I take off slowly. This does not happen every time but I would say 20% of the time. The pump only runs for a second or 2(low speed). The traction control light never come on when this happens but if I deactivate traction control the problem goes away. I had a scan run and at a dead stop all 3 sensors show 3 MPH. We were able to get the pump to run when the scanner was plugged in and all 3 sensors showed the same MPH. When driving all 3 sensors show same MPH also. The scanner showed no problem codes and I do not have any trouble lights on. I called Module master and the did not think it was the module. Can any of you Gurus help me?

It sounds like you need to have the system recalibrated.
