B2204-55 ECU Configuration Mismatch. Not Configured and Active.
4X4 went out in the middle of winter. Replaced PDU and now it's down again. 2018 Cherokee Limited. That is the code it throws now. Any ideas? Someone thought it could just need to have its software upgraded. It's frustrating that it only has 70K miles...
