We have released Venus OS v3.53 that fixes the Cerbo MK2 VE.Can port 2 issue for (almost) all systems that we analysed via VRM.
The complete troubleshooting processs for this is:
-
Check if VE.Can Port 1 is in use as well. Our VRM stats show that often it’s not. In case not, replug and reconfigure the GX to work on VE.Can 1 port instead
-
If both ports are needed, update to Venus OS v3.53 or later, which will in most cases fix the issue.
-
Only if that doesn’t fix the issue, contact your dealer for further troubleshooting and if necessary replace that Cerbo MK2 (under warranty)…
Venus OS v3.53 fixes the VE.Can port 2 issue for most Cerbo MK2s, but we’ve seen some of them where there really is a hardware issue and RMA is the only solution.
