Good evening

This range rover has a fault of p0642 reference voltage low. After many hours of testing and retesting I have purchased a new PCM from Landrover. Using genuine IDS and Landrover SDD I am trying to programme the component to the vehicle.

I can't find anything to match the pcm to the vehicle. It must be immobiliser related as the old ecu would run just lit the dash up like a christmas tree and the new pcm won't turn the engine over.

Dare I say it but this is where autologic used to make life easier.....

Any info or guide would be hugely appreciated

Regards
Ben
