Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Principles of Operation
Module Configuration
There are two modes of configuration data. The first type requires configuration information so that the module can interact with the vehicle correctly. This information will be transferred to the new module using the Jaguar Approved Diagnostic System, so that it will contain the same settings as the old module.
Modules which require configuration when installing a replacement module are:
- Engine control module (ECM)
- Transmission control module (TCM)
- Audio unit
- Drivers door module (DDM)
- Rear electronic module (REM)
- Front electronic module (FEM)
- Amplifier
- Intrusion sensor module
- Multifunction voice activated control module
- Headlamp levelling module (ADHLS)
- Electronic park brake (EPB) module
- Instrument cluster and message center
- Climate control module
Customer Driven Preferences
The second type of configuration data is customer preference driven. These are items that the customer may or may not want to have enabled. Typically, customer preference items can be toggled on or off by the use of a compatible scan tool. You may need to ask the customer which preferences they had enabled prior to installation of the new module, although after installation they will automatically learn the settings by receiving information from existing modules.
To carry out the customer configuration process, use the Jaguar Approved Diagnostic System. Refer to the Dealer Options Index for modules on the vehicle that have customer preference items. Configure the items as needed.
Modules which can be configured with dealer options are:
- The FEM.
- The instrument cluster and message center.
- TCM (market configuration).
- ECM (market configuration).
- Intrusion sensor module.
- Multifunction voice activated control module (market configuration).
- Audio unit (market configuration)

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
