Error Code :172 CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent).
It is very common for steering wheel position sensors to fail the startup test phase, often because they are on a less used part of the variable rheostat-type sensor. If it happens too often, you can replace the steering wheel position sensor. Otherwise, just drive for a bit, shut it off and restart.
