2013 Dodge Charger R/T 5.7L AWD

So a month or so ago the low air pressure sensor came on for one of the tires. not much, just down 2lbs. then the 'service awd' light came on. put air in the tire, everything went away and was fine. last night, 'service awd' light came on again as I was driving, all tire pressures are correct. I haven't done any checking or diagnostics yet, but was looking for a bit of insight from anyone who may have experienced this before. hopefully, any advice or suggestions may help shorten my time spent to fix it. thanks in advance for any help, much appreciated.

so, in addition, now the check engine light is on. scanned and code "U0002 - High Speed CAN Bus Performance". I believe these issues to be related. any thoughts would be appreciated, thanks.
