Hello CarID1956, thanks for your Question in the community.
Your asked fault Code means: 5022 event: No CAN message was received from the engine control unit ECU.
This ECU talks over the CAN Bus with the other Control Units.
I think there is an communication error and you should make a hard reset. That means you should disconnect the battery for few minutes, or a hour,
Are the other CU´s still working and theres no Problem?
Check the complete System for faults and then you should diconnect your battery if theres no other Problem.
What you can do is looking for the CAN Distribution near the entered door on the right side.
You can check the Bus System if there is no communication
