2004 GMC Yukon XL Denali Traction Control

I have been having the traction control issue for a few months and after reading through the posts, I decided to go with the simplest option of removing the sensors and sanding the area where they sit on the hub. Took me less than an hour to do both sides and spray off the sensors and inspect them for cracks, etc. I have driven about 100 miles since and drove on the roads where the problem always happened an I haven't had the issue at all since sanding the hubs. Sometimes the simplest ideas are the best.

ISI - my hat's off to you! Thanks for sharing your experience. I hope other people will try this before going through the expense of replacing parts!

I have had the traction control problem. When you take off the truck slows down so annoying. I ended up pulling the 60amp fuse out of the engine compartment fuse box. VCSE or something like that. Disconnects the Stabilitytrac Three lights popped up on the dashboard, ABS, TC and Brake.. but the truck doesnt do it anymore!

There are several problems with totally disabling the system. For one, the base brake system relies on the ABS (antilock brakes) for brake proportioning operation. At one time an ABS system was installed on top of a base brake system with a mechanical proportioning valve. This is no longer the case, and the ABS system prevents the rear wheels from over braking and locking up which can result in a loss of directional control. The ABS system is also responsible for deciding if the drivetrain needs to engage 4WD or not by measuring wheel slip speeds. That might not be the case with a 2004 but definitely applies to cars that are designated AWD (all wheel drive) and do not take input from the driver to engage the 4WD.

The Stabilitrak system assists the driver with helping maintain directional control under a number of different conditions. Any wheel that is locked up or has lost traction and is spinning or slipping can lead to a loss of vehicle control. That's why when the system thinks that a wheel has lost traction one of the symptoms is limited throttle control. In some cases, increasing traction means decreasing engine torque. which explains your symptom above. Your "solution" essentially works put to adding a problem to the vehicle instead of solving a problem.
