Hi everyone, I need some help because I couldn't understand where the problem exactly is. My friend has a Zafira B, and all of a sudden the board computer is saying "no function" when he's trying to access it. I tried to connect the opcom but all I got was b-3446 error code. I tried to access the EHU through the opcom but it couldn't connect. Even the connection with the cim failed. Any help please???

Zafira B - BC no function
Quite possibly a software glitch. My usual answer to all electrical and or software faults is to disconnect the battery negative lead and leave it over night then reconnect it in the morning. This resets the software in the ECU and modules so if its a software fault then this may rectify it. You would be surprised just how many electrical or software faults doing this fixes.
