Hey how are you,I will try to help you with this issue

I would check the battery for 12 volts and alternator for 14 volts when running ,

other then that You will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the Vehicle modules and based on these fault codes we can pull up a Pin Point troubleshoot
and be accurate on it ,If you do get it scanned ,you can post the fault code back here for me and I can help you further on it and be more accurate .

now with that said the command units might need to be reprogrammed or replaced , i seen few cases for that as lon as the charging system is working correctly

Merry Christmas and happy new year

You are very welcome :)
