418-01 : Module Configuration

Diagnosis and testing

Module Configuration

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 centre

•

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.

•

The instrument cluster and message centre.

•

TCM (market configuration).

•

ECM (market configuration).

•

Intrusion sensor module.
