A/C - 'Temperature' Messages Displayed

No.: LS415-004

Issue: 1

SECTION: 415-00 - AUDIO SYSTEM

Infotainment 'Temperature' Message(s) Displayed

AFFECTED VEHICLE RANGE:

Range Rover Sport (LS) VIN: ALL

CONDITION SUMMARY:

Situation:

A customer may report a concern that a message 'temperature shutdown', 'CD over temperature' or 'system over temperature' is displayed by the

infotainment system and that the unit no longer functions.

If a high heating system temperature is selected in combination with a low fan speed, the temperature build up in the central area behind the center

dash can lead to the infotainment system shutting itself down to protect the electrical circuits. This is a feature for the protection of the system.

Action:

New heating system control software has been developed to redistribute the airflow at these settings to avoid this problem. Should a customer

express concern regarding the above, refer to the Service Procedure detailed in this bulletin to update the control software to the latest configuration.

1. If WDS CD13 (Patch File 6 or later) or IDS DVD102 (Patch File 1 or later) is installed and being used, go to step 6.

NOTE:

A software patch installation help file located on GTR provides instructions for the patch file installation process and could take up to six

minutes to download depending on connection speed. For information on how to confirm that the patch file has been correctly installed

onto WDS/IDS, refer to the applicable Patch Process Help File located in GTR. Global Technical Reference (GTR) lookup sequence is as

follows:

GTR Home > NAS > Diagnostics/LA - Discovery 3/LR3/2006 > Patch Files > "Patch Process Help File - T4WDS or Patch Process Help

File - IDS" link.

2. Logon to GTR from an internet connected PC and download the WDS Patch Process 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 appropriate 'Patch Process Help File - T4WDS' or 'Patch Process Help File - IDS' file link.

NOTE:

This could take up to twenty minutes to download depending on connection speed.

3. Using the help file as a guide, follow the instructions to download and save WDS CD13 Patch File 6 (or later) or IDS DVD102 Patch File 1

(or later).

4. Install the software patch file 'WDS CD13 - Patch File 6' (or later) or IDS DVD102 Patch File 1 (or later) on the diagnostic machine.
