I have a 2007 Avalanche with 168,000 miles. It is in great condition, and runs excellent. My problem is the Stabilitrak light is on. Let me back up this problem. For about a year, my tire pressure light would go off and on daily, said it needed service. If I checked the pressure on the dash, one tire would have no reading. It would come and go often. Figuring it was a bad wheel TPS I ignored it. So a couple weeks ago I had to change the driver side engine mount. Took it out the side wheelwell. I had to unplug the wheel speed sensor for the ABS. No big deal, until I try to drive it and now have the Stabilitrak light on. I figure I had messed up the ABS wire when I unplugged it, so I put in a new wheel hub speed sensor an wire. This did not help. The truck runs and drives good. ABS works, traction works, but the light is still on. Now the really strange thing is I no longer get Tire Pressure faults. All tire have a reading now. Do I have a bad BCM? I do not have any check engine light.
