When I start my 2011 Sierra I get a service stabilitrak/service traction control message on the DIC and the orange traction light in on. It happens as soon as the truck starts and before the truck moves or steering wheel moves. It throws a code U0124-00 lost communication with yaw sensor. In addition my abs is also no working but no abs light is on. Does anyone know where the yaw sensor is located and any help troubleshooting the code would be greatly appreciated. Thanks in advance

I believe that the yaw sensor is an integral part of the inflatable restraint sensing diagnostic module. Under the driver's seat carpet. Check the module and connector for corrosion.
