WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
A telematics control module replacement should only be carried out after all other troubleshooting and diagnosis steps have been taken (including raising a TA for further assistance) AND has been approved by Retailer Technical Services. You should not perform a telematics control module replacement in the hope it will resolve a concern that you cannot diagnose. During the "TCU Replacement Routine", essential information relating to the new unit is sent to the Jaguar Land Rover off-board database, therefore it is crucial that the telematics control module replacement routine is ran in full.
- Physically fit the telematics control module as instructed in the Workshop Manual.
- Ensure the Jaguar Land Rover approved diagnostic equipment has been updated to the latest version.
- Don't use a "dongle" or an older version of the Jaguar Land Rover approved diagnostic equipment.
- Run the "TCU Replacement Routine" via the Jaguar Land Rover approved diagnostic equipment in an area with good signal.
