Bump a scan. So we have reliable data to work with.

For example:

Text Identifier U112100 is: "Databus missing message". Not: DATABUS MESSAGTE MISSING
Text Identifier U112300 is: "Databus error value received". Not: DATABUS ERROR VALUE RECEVIED

Not to mention that it is useless to have DTC-TI only (without DFCCs), but especially without the context which control unit provided them.

Provide a scan instead of bumping with invalid, incomplete and wrong information.

@CGCGCG

First try to charge 12v battery
If ABS error remains, check the fuse, also for fluid pump 
Can you clear some fault codes with  the ignition on? And do they become active again when you crank the engine?
But, also, with the fault codes you have, the engine should start.
I can provide you a CAN diagram but only monday
don't forget to hit thanks and reputation buttons
