RECALL: Transfer Case Control Module Tune Download
AFFECTED VEHICLE RANGE
CONDITION SUMMARY:
IGNITION KEY REMOVAL WITH GEARBOX NOT IN 'PARK'
Situation:
Land Rover has decided to recall all affected vehicles to install updated Transfer Case Control Module software. On the affected vehicles, when the ignition is switched off, after a period of time it is possible to remove the ignition key when the transmission shift lever has not been placed in the "P" (park) position. As a result, these vehicles do not comply with FMVSS 114 (CMVSS 114), which requires the transmission shift lever to be in "P" (park) for the key to be removed from the ignition.
Action:
Refer to the Repair Procedure of this bulletin for instructions on the tune update installation.
PARTS:
No parts required
TOOLS:
WDS Software CD13 with Patches 1, 2, 3, 4

REPAIR PROCEDURE
DOWNLOAD UPDATE TUNE
1. If WDS has previously had the patch file (WDS CD13 - Patch File 4) installed, go to step 5.
NOTE:
The software patch installation help file provides instructions for the patch file installation process and could take up to six minutes to download dependent on connection speed. For information on how to confirm that the patch file has been installed onto WDS, refer to the patch process help file.
NOTE:
GTR lookup sequence is as follows:
GTR Home > NAS > Diagnostics/LA - LR3/2006 > Patch Files > "Patch Process Help File" link
2. Logon to GTR from an internet connected PC and download the WDS software patch installation help file as follows:
^ Select 'Home' from the menu at the top of the main page.
^ From the menus on the left of the page, select 'Diagnostics' as the 'Information Type' and select the relevant model and model year.
^ From the 'All Information' results, select 'Patch Files'.
^ Click the file link 'Patch Process Help File'.
NOTE:
Patch file download could take up to twenty minutes dependent on connection speed.
3. Using the help file as a guide, follow the instructions to download and save WDS CD13 - Patch File 4.
CAUTION:
Before upgrading WDS CD13 with Patch File 4, Patch Files 1, 2 and 3 MUST be loaded. Each patch file must be downloaded separately and in sequence: Patch 1 then 2 then 3 then 4. Patch files may not be loaded any other way than one patch at a time.
4. Install the software patch file 'WDS CD13 - Patch File 4' into T4/ WDS and verify that WDS successfully restarts.
CAUTION:
The diagnostic lead must be correctly secured to ensure it cannot be accidentally disconnected during software update.
NOTE:
An approved power supply (Midtronics PSC550) must be connected to the vehicle battery during diagnosis/module configuration.
5. Connect the power supply and diagnostic equipment to the vehicle and begin a WDS session.
6. Note the current software levels of the control module as follows:
^ Enter the vehicle details.
^ Select the 'Vehicle Configuration' tab.
^ Select 'Module Information'
^ Select 'Network integrity test'
^ Note the software part numbers displayed on the screen (latest level software is NNV504230).
NOTE:
During module configuration, the on-screen software part number information that WDS will display can be checked and compared to the software part number noted in step 6 above. If the same tune level is displayed, the vehicle already has the desired software level and the tune download process can be aborted.
CAUTION:
Vehicle Preparation must have been performed prior to any attempt to use WDS for this tune download.
7. Configure the Transfer Case Control Module:
^ Return to the 'Vehicle Configuration' screen and select 'Module Configuration.'
^ Select 'Configure Existing Modules.'
^ From the sub-menu, select 'Transfer Case Control Module.'
^ Check the tick-box to continue and follow the on-screen instructions.
^ Compare the on-screen software part number information that WDS will display with the software part number noted in step 6 above.
^ If the same tune level is displayed, terminate the tune download.
8. Repeat step 6 to confirm the software level change.
9. Exit the WDS session and disconnect the diagnostic equipment and battery charger from the vehicle.
