IPC and SDM U1255

IPM B1343 - Air Inlet Door Movement Fault

RSS C1785 - ICCS2 DL Right Output Short Circuit to GND |
Have you serviced recently the EBTCM module?
Disconnect the CVRSS module (both connectors). Does the RSS codes go to History? How about the U code?
If the U code is still active the 80% your EBTCM module is defective. The IPC, EBTCM and SDM modules are all connecting to a common point on the data bus (along with the diagnostic connector pin 2).
When the car doesn't start disconnect the EBTCM connector and try to start. If it starts...well EBTCM is shorting out the data bus (also the ICCS lines).
