ISSUE

We have received multiple reports where a failed Telematic Control Unit (TCU) software update has caused limited functionality of the module.

When attempting to complete a software update to the TCU, there maybe either, or both of the following error messages displayed;

'Software download failed'
'Determining parts to be updated' (When this error is displayed the user is prevented from being able to exit the application)

CAUSE

Some of the TCU software files are corrupt.

An error within the PATHFINDER software files prevents the application from continuing.

NOTE: This manual patch detailed in this communication should be installed before attempting any TCU programming; the manual patch will prevent the software download failure leading to the reduced functionality of the TCU. If a software update has already been attempted and has failed, applying this manual patch will not allow the software download to pass. The module will not be recovered.

This manual patch should be installed before attempting any TCU programming.

ACTION

NOTE: The Manual Patch needs to be applied to PATHFINDER 199

This workaround will load a software file to the Jaguar Land Rover Approved Diagnostic Equipment using the Manual Patch Update process.

This Manual Patch will stay on the JLR Approved Diagnostic Equipment.

Restart the JLR Approved Diagnostic Equipment
Select 'Manual Patch' Icon on the Application Launcher screen. Make sure that both Symptom Driven Diagnostics (SDD) and PATHFINDER are closed before opening the Manual Patch downloader.
A pop-up will be displayed for Manual Patch downloader
Enter 'MP_PF_L0039' in the Patch Name field.
Select 'Start'.
The Manual Patch downloader will then download the manual patch.
When the patch download has completed, a message will be displayed, asking the user to confirm that the application can run the manual patch. Select 'Yes'.
When complete, the following message will be displayed: 'Successfully downloaded and started manual patch. Please make sure that the patch has installed successfully.'
NOTE: This message will end after 10 seconds.
Start a new diagnostic session.
Proceed to update the Telematic Control Unit Module (TCU)

If this Manual Patch fails to correct the concern then a Technical Assistance should be submitted to Local Technical Support (LTS).
