ISSUE

When attempting to update the software on a module using JLR VCI, SDD shows the error message: "Error code 903 - Incorrect Service Identification" 

CAUSE

We suspect that the latest update of the JLR-VCI is causing

missing diagnostic messages between the JLR VCI and the vehicles modules.

PERMANENT CORRECTIVE ACTION

This concern has been resolved with the release of SDD version 159.00.  The manual patch will no longer be available to download and this SSM will be deleted in 7 days.
