Help with CAN communication
Hello to all - I am working on a 2012 ML350 and the car was towed to me as a non start, non driving. The car has power all lights are working, windows, power seats, rear door and Radio. The wipers don't work, hated seats don't work and the car is not cranking and starting up. There we a bunch of codes present (the car was at another garage), so i decided to erase everything and start with whatever comes back. Here is a list all fault that come back right away.
IN ME i have:
U010182 No communication with TCM message is lost
U010387 No communication with ESM message is lost
In ESP module:
C085100 -variant of coding transmitted via CAN bus by N73- EIS/EZS is implausible.
Park distance control:
U042300 - Data from Instrument Cluster is implausible
U041500 - Data from ESP module is implausible.
U010100 - Communication with TCM is faulty.
Back up camera:
U010187 Communication with TCM is faulty
ARS (rolling):
U010000 - Communication with ECM is faulty
U041500 - Data from ESP is implausible.
I did some testing and looking around the car and all fuses and relays are good. Both Batteries were just replaced. The Main is Die Hard Platinum and the Aux is OEM. Resistance on pin 6 and 14 with battery disconnected is 60 ohms. with battery connected is 158 ohms - which is odd when power is present. Also voltage on pin 6 is 2.5 -2.52 volts and pin 14 is 2.38- 2.4 volts. I did an EIS/EZS test and the switch is responding OK on terminal 50. I have been reading/searching a lot and can not find anything. If anyone can shed some light with a similar problem would be greatly appreciated.

yes I did after $1,500 - turned out that someone did cross jump the battery terminals and blew a fuse that I did not know about - 150am fuse that supplied all power to all modules
