Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Have you had the fault codes checked at all to see what codes are set with this issue here?This needs done with either a dealers sds machine or a scan tool that will plug in and communicate with all computers in your vehicle.
Let me know so we can continue,thanks Pete.
The auxiliary battery is for the electronic shifter motor on the side of the transmission/gear box.This is in place in case the main battery fails this way you still have power to shift the vehicle into neutral to have it towed or pushed.If this battery is dead it needs replaced.
There is an update for the software in the power steering control unit for issues with the steering operation that should be checked into and done if needed.This has to be checked and done by a dealer who has access to an SDS machine to do this here.The bulletin number for this is LI46.35-P-054644.
In some cases the auxiliary battery being dead can cause issues with all electronics communicating properly and may cause other issues here possibly with the steering so it would be a good idea to start with replacing the auxiliary battery and then clear out all and any fault codes and see if the steering starts to work from there properly.
