Both of these codes here are communication fault codes.One relates to loss of communication with the BAS control unit itself.Make sure all fuses are o.k. and that no fuses have blown.I can see if I can locate which specific fuses need checked here if you want that info.If the fuses are o.k. inspect the wiring and connections at the BAS control unit and make sure they are all o.k.If these are found o.k. one of the most common causes is a faulty BAS control unit itself.

This sounds like the BAS control unit itself is at fault which can be common to fail needing replaced.I have seen it fail before.The communication issue may also stretch into the AAM due to the fault with the BAS control module itself or both may be faulty needing replaced.I would start with the BAS control unit first to see if this resolves all of the issues here.Make sure the wiring connections to it and running to it are all o.k.
