Engine Immobilization

There are two methods of Engine Immobilization featured on the new Range Rover; engine crank disable and electronic engine immobilization. The electronic engine immobilization is controlled jointly by the engine management systems Electronic Control Module and the BeCM.

If a crank signal is detected when the alarm is set, the "Engine Immobilized" message will be transmitted to the instrument pack, and it will not be possible to start the engine.
