Guys,
A friends 1.6 Meriva 05 reg wont start and the following codes are displayed.

Total number of fault codes: 5
P1615 - Wrong Vehicle ID from Body Control Module
(00) - Present
P1616 - Wrong Vehicle ID from Instrument Control Module
(00) - Present
U2107 - CAN-Bus no Communication with Body Control Module
(00) - Present
P1482 - Fan Relay 2 Signal Low / Open Circuit
(04) - Present
P1483 - Fan Relay 3 Signal Low / Open Circuit
(04) - Present

Could this be a module problem or is it more likely to be a wiring connection. He did say he had noticed the rev counter dropping to zero sometimes before the problem.
