help with fault codes

[vectragsi3.2]

hi all just been out to read the codes that has stored and one was the glow plugs but delving further into it i found these codes:

u2103-00 no communication with can-bus (high speed)
b1020-71 no communication with rain sensor
u2141-71 invalid data from rec (rear electrical centre)

now i know about the rain sensor but dont understand why its never worked since ive had the car as its on the windscreen and never been messed with by me????

Is it possible that one of the ribbons from the REC for the dimming mirror has been damaged?

[vectragsi3.2]

the dimming mirrors work fine but my drivers sunvisor light doesnt work could it be that?

[John LE]

Sorry miss read your post. I read rain sensor but thought rear view mirror

Yes we they all work off ribbons from the REC so it could well be some damage to one of them

lol will have a look at the sensor it could be that it has come loose???

If you have a sun visor that isn't working i'd be checking the roof looms tbh. Have you done anything that would have disturbed the wiring up there?
