Hello,

I have the following error codes on my corsa D. I have already cleared them a number of times but they keep on coming back.

u2104-00 can bus mid speed counter Over run
U2102-00 can bus mid speed max configuration list not complete.

U2100-00 canbus mid speed communication malfunction.

Any ideas on how to fix them?
