The airbag light on the dashboard don't goes off. What I need to do solve this? I've connected the Allcoms but that didn't solve
Cheers

Could be a number of things..... On my TD6 it was the connector under the passenger seat that was defective, the fix for the MOT was not advised but I was young

It could be any connector anywhere - start with the easy ones to get at - one that is often overlooked is the one on the positive battery terminal which often suffers from corrosion (it's yellow in colour & has relatively small wires going to it).

Also, try a full reset ;

Let the car shut down completely with the bonnet up and disconnect both battery terminals.

Then, short out the positive & negative terminals on the car. for a few seconds - this will reset all the ECU's.

Reconnect the battery & start the car - you will have a "Suspension inactive" or similar warning on the dash - turn the steering from full lock to full lock to reset the warning.

Hope this helps. 2003 Range Rover Vogue TD6

Thanks for your answers.
I've tried all of that and didn't solve. I check the wires and the connector on the battery positive terminal, the connectors under the seats and now the Allcoms give me the info "driver airbag firing circuit 1". Where can I go now?
