Need help: CEL on - Error code: CAN

[BrunoMM]

(I searched)
Hi gentleman,
I was getting back home after a 100miles round trip when the CEL light came on. The error code was CAN (comm. between ECU and panel). As the light came on all the information on the panel disappeared (RPM, speed, oil temp...). I stopped shut the engine down and tried to start it again several times (with the CAN message still displayed), unsuccessfully. It only started up after the message disappeared after a few minutes.

I had this problem 2 more times within a week and decided to go to the dealer. The dealer here at my city (Sao Paulo) is not so reliable... The techs told me that they could not find where exactly the failure was and their conclusion was that it was on the panel   

Inputs? Can someone help me help my incompetent dealer?
Anyone here ever had the same problem?

ps:I had this problem with the stock ECU and DP ECU.

Thank you guys,
Regards from Brazil

I have not had any can bus problems on my duc, but do have some can experiance in automotive.  The auto market started using can in the early '90's and it has been fairly reliable.  Most problems tend to be wiring over control modules.  All the systems I have seen use 2 terminating resistors, some inside control modules some outside.  The ones outside of control modules are common sources of problems.  If the problem happens with 2 different ECU's it is most likley either a damaged wire or a cluster.  Sorry I cant give you better info but can network problems tend to be hard to find with out a scope.

I agree with caperix, most likely wiring or cluster.  The problem will be hard to find when everything is working correctly.

Glantern had that on his 1098 it took a while to figure out but it was a pinched or grounded wire in the dashboard harness.

Thank you so much for your help, Guys. I'm glad to see that it might not be as bad as the dealer's techs told me.
I'll keep you updated on the results.

As you guys said, it was a wiring problem.
Now it's solved.
Thank you !!!
