Hi all

Recently purchased a 1.9 Vivaro 2006 of a friend, Drove it home, changed the battery and for some reason it wouldn't start again:

  • i noticed all the electrics were working except for the Hazards/indicators, Central Locking and the immobilizer light is completely blank.
  • I took out the BCM and it was absolutely filthy, but i find it odd that this issue occurred after i put a new a battery in; was fine prior
  • also replaced all the main fuses on the battery terminal with no luck.
i am about to send of the BCM to a repair company; however, i just want to make sure that the BCM is faulty and not power to the BCM. but is it odd for the BCM ti Fail completely just like that?

  • does anyone know which fuse is linked to the BCM so i can check this?
  • Also plugged in Diagnostics and stated it cannot communicate to BCM but can communicate to Engine and ABS (just said no communication to ECU)
  • anyone had any issues similar to this before? cant find anything about immobilizer lights being blank.
  • i Have read how wires tend to corrode, so do not want to spend hours tracing wires and taking it all apart :(
any advice and help would be appreciated.

Did you find out what caused this as i have exact same problem
Hi mate, sorry for the late reply.

I took out the BCM and sent it to a specialist on Ebay who repaired it for me and it was working perfect after.


the link above is who i used. His service was brilliant, cheapest and he sent it back to me quick and whatsapped the diagnosis.

Hope this helps

Hi,

So sounds like you have the same issue. I took the BCM out and send it to some bloke on ebay.


he fixed it, sent it back and my van was perfect. really recommend him.

if you have any issues or questions about getting the BCM out, let me know, happy to help.
