Connecting an MX808 to a 2014 Buick Regal Premium.  Every module on the vehicle is detected except the power steering module.  Autel tech support says this is because the module is faulty, but there does not seem to be any issues with the vehicle steering.  Can I use the scanner in some way to find out more about the power steering module? 

 I think it was a full system scan.  Several modules reported low voltage which I suspect is because the battery is on its last legs.
