Question

I purchased a 2012 Mercedes E350. The battery is OK (checked), I replaced the starter relay, all fuses are OK.  I have a OBD II  tester.  I have 2 DTC codes

U10388  Diagnostic CAN communication has a malfunction.  Bus off.

U11600  A Bus keepawake unit was detected.

 

All electronics in the car work. It was a flood damage car. Under the carpet looks fine.
