Hi I have a doblo 2008. Came to the van one morning and the immobiliser light was on. Had the AA out to it and think it's the chip that's gone faulty. Had the chip tested and that seems fine. The coil for the chip also seems fine. I'm wanting to check the wiring from the ignition barrel to the ecu but don't have the schematics. Any help on schematics or a possible solution would be much appreciated.
