I have a problem with Opel Zafia B, year 2006, engine Z18XER, won't start.
OP-COM can't communicate with modules that use high speed GMLAN (CAN).
If i disconnect the CAN line connectors from the Underhood Electrical Center, OP COM can communicate just with CIM, and give: no high speed CAN communication. If put back the CAN line connectors to UEC, no communication with CIM.
For test, replaced the CIM and the UEC, but same problem.
My question is, if i disconnect the engine ECU, is it possible to communicate with other modules that use high speed CAN ?
Thank you very much !

Check the underhood electrical center maybe cables are broken by water or something else

Problem solved.
The engine ECU and the Power Steering Module, both was damaged.
Thank you very much for help!
