Recently Installed a new ECM and Immobiliser still not starting. I am pretty sure It is Immobilized. I called Land Rover and explained what I needed to see if they have the capability and they seemed clueless and told me I needed to buy new modules that used ones won't work. Can anyone with any experience with testbook or other experience let me know the steps needed to relearn the immobilizer and ECM together so I can communicate it to them exactly what needs to be done? THANKS! Any info helps!
You will need a special Land Rover specific tool to reprogram the immobilizer to the car. ECM won’t work unless you buy new or reflash it to your VIN
