Service Precautions: Notes

Turn ignition off before connecting or disconnecting any control module connectors.
When cranking or idling engine, DO NOT disconnect ignition coil cable or spark plug cable.
When performing an ignition spark test, check one spark plug at a time and ensure spark plug is grounded.
When performing compression test, ensure ignition system is disabled.
Vehicle security system is equipped with a battery back-up feature. Before disconnecting vehicle battery power, ensure vehicle security system is not armed.
When vehicle battery power is disconnected or remote transmitter battery is replaced, the vehicle security system remote transmitter (handset) must be resynchronized.
If the Engine Control Module (ECM) or vehicle security system Electronic Control Unit (ECU) is replaced with a different unit, the vehicle will not start until the ECM and ECU are resynchronized. The vehicle security system uses rolling code technology.
All ignition keys are equipped with a transponder. If a replacement ignition key is needed, it may ONLY be obtained from a Land Rover or BMW dealer. If an attempt to use an ignition key with no transponder occurs, vehicle will not start.
When vehicle battery power is disconnected, windows and sunroof will need to be calibrated.
