ESP/VDC Problem

[Kamen666]

Hi to everybody,this is my first post here,and i'm beging for help
Before one year i bought a Alfa Romeo 156 12.2002 1.9 JTD
I love this car !
But from one month i have a serious problem
The ecu give me a constant mistake in VDC in my car
I go about 5-6 six service,they put my car on tester and nothing....
The mistake is:
C 1520 - Can terminal -> bad connection
C 1521 - Can Terminal -> bad connection

and nobody can delete this mistake from ECU,and nobody can help me here in Bulgaria...
Can you please tell me where i can find these terminals to clean them (whit a contact spray for example),or can somebody show me a grafic or something helpful.
this forum is my last hope.....
Sory for my bad english
Greetings from club alfa romeo bulgaria
Sincerely
K.Todorov

Does the ABS working on your car with this failure?
Try to check the ABS sensor elictrical line from wheel's hub to ECU... It's can damaged!!!

I suspect this has something to do with the steering wheel angle control sensor ,
try to undo the top end of the steering wheel and check the wiring with it's terminals.
Anyway it would be better if you could find a service with an Examiner because in case of the sensor failure it has to be calibrated after it is refitted.
The wiring is a never ending story with alfas, there are always issues with them.

If it was the VDC with the ABS together then I would recommend to change the battery but this is not the case.
