The Stabilitrak service notification comes on at random with my van (2014 gmc savana). It does have a code for the steering angle sensor (c0710-17,c0710-5a) but it seems to be working just fine. It does throw a code for Multi axis Accel sensor (c0292-07) basically saying it doesn't like the angle sensor... I guess it still can tech work even if the voltages are off?

 

It might need the steering wheel sensor to be zeroed out? It takes a special scan tool to do that.

 

It might need to be reset, or it could just be that the sensor is going bad. My yaw sensor ( MAS ) was intermittent for a while before it went out entirely.
