Last time I send my car to my Chevrolet agency due to a drawing message "a drawing of car with a mechanical key" ...during revision I saw over the hand-held terminal (DTC) in the shop , "50 messages", ... mostly regards to CAN Bus communication problems, on which the service manager told me thay these messages are not true messages. They were told by one of the representatives of Opel in Mexico, that these messages come up but should be dismmissed, I mean not take care of them....
in specific... some of the messages said: for example (translated from spanish to english)
a) #U2103 "failure over the chassis module controller BCM. Intermitent failure.
b) #U2117 " in BCM module, , No communication from Bus CAN to DIS.
c) #B3717 "no Bus CAN communication to UEC.
d) #2116 "No BUS CAN communication to IPC (instruments block).
e) #U2113 No BUS CAN communication to SDM (airbag diagnostics and detection system....
f) ...etc. etc. etc. etc. etc.
well...just to mention some of the messages..............
ofcouse I don´t agree, and I still talking with them and get them fix it.
Can someone get me some advise on this please? what might be happening?
I know CAN protocol is a very old, but trusting communication,...born in Germany kind of serial comm, but I think that there might be something wrong in one of the modules, ... there is too many messages related to CAN Bus communication problems,
or does this regular happen to a new VEctra-C ????
