This fault here can be due to an internal electrical fault in the Front SAM control unit itself.I have seen this fail before in the past and cause electrical issues like this here.I would have the fault codes checked in the front sam unit to see what codes are set using a compatible scan tool or dealers sds machine.Once this has been done any codes set will need diagnosed to help locate and correct this issue here.
