NAVIGATION CONTROL MODULE (NCM) DROP OUT - REPROGRAM NCM - SERVICE ACTION S524

TECHNICAL SERVICE BULLETIN

Issue

On 2005-06 MY XJ vehicles equipped with navigation  within the above VIN ranges, the navigation control module (NCM) is not initializing correctly when the ignition is switched on and the engine cranked, corrupting the B2B fibre optic network ring.

The effects on the vehicle are as follows:

• Vehicles equipped with premium audio and navigation experience complete loss of sound and audio functions, loss of navigation, phone and CD stack (if equipped).
• Vehicles equipped with standard audio and navigation experience intermittent operation of radio and single slot CD and no sound for external media e.g. phone, voice, navigation and CD stack (if equipped).

Action

At the earliest opportunity, you are requested to reprogram the navigation control module using navigation software disc JTP 1072_1 (V8.60) or later.

The navigation software disc will be supplied one per dealer, directly from the factory. If you have not received your software disc, please contact the supplier/shipper directly:

A number of vehicles have had the navigation control module reprogrammed prior to dispatch of the vehicles. Please check DDW to ensure that the vehicle requires this rework prior to carrying out any repair. DDW will be updated with only those vehicles that require rework action.

At the time of confirming a booking for vehicle repair, please ensure that all outstanding Field Service Actions are identified to ensure the correct parts are available and adequate workshop time is allocated for repairs to be completed at one visit.

1. Open the luggage compartment lid.
2. Start the engine and allow to idle.
3. Remove the map DVD if present.
4. Insert JTP 1072_1 (V8.60) or the latest level operating system software disc.
5. The system should automatically update from the inserted disc.
   NOTE: If the ignition key is turned 'OFF' or the disc is ejected while the software is updating, the unit will lose all software and will display a blank screen. If this happens, leave the system for approximately 20 minutes with the ignition switched 'ON' and the software disc inserted, the system should then recover to complete the update. If the system does not recover the navigation DVD unit will require replacement.
6. When the update is complete the system will display the 'Leaper' screen and then time out to display one of the sub-systems (Air Conditioning, Radio, Navigation or Phone).
7. Remove system software update disc.
8. Re-insert the map DVD.
9. Turn the ignition key to the 'OFF' position.
10. Close luggage compartment lid.
    NOTE: For future reference, use a permanent marker to indicate S524 on the software disc.
