Stabiltrak problem

[dveenhuis]

My 2004 Yukon Denali experienced a "Service Stability system " error yesterday and the truck immediately slowed to a stop. The vehicle would not move until the engine was revved to 1500 rpm. I had the vehicle towed to a repair shop and today they test drove the vehicle and could find nothing wrong. I've seen a few old posts on other sites about this issue, however, I wondered if anyone in here has heard of this problem?

I found this on another site:

your satabiliTrak isn't working...

The StabiliTrak Electronic Stability Control System helps you stay the course by detecting the difference between the steering wheel angle and the direction the vehicle is actually turning. StabiliTrak "reads" the steering wheel position, the amount of sideways force in play, the speed of the vehicle and the vehicle’s response to steering wheel input. It then uses the brakes and, if necessary, adjusts engine torque to help you keep your vehicle on track.


Have the shop pull the codes to find out which sensor has gone bad. Most likely the steering angle sensor.
