Traction Control Error- Stabilitrack failed

[HummerJim]

I've had that twice after power washing the undercarriage and once after going through a creek in about 12 inches of water. Each time the light has gone out after about 15 minutes and I've pressed the 4WD buttons at rest. My guess is some connector or sensor doesn't like lots of water, however, the light has always gone out, so it's not something that bothers me.
When it comes on, I notice no difference in performance or traction.
