Car Configuration File (CCF)
CAUTION:
If a new instrument cluster is to be installed, using the Jaguar Land Rover approved diagnostic equipment complete the instrument cluster renewal procedure - Instrument Panel Cluster Control Module [IPC]/replace ECU. The instrument cluster subscribes to the car configuration data published over to Controller Area Network (CAN) by the body control module/gateway module. The information is used to configure the instrument cluster settings and display to the cars specific requirements
The car configuration file contains all relevant data about the specification and market condition of the applicable vehicle, immobilization codes and driver personal settings. This information is retained in the gateway module and shared with other modules over the CAN network enabling each system module to detect which systems and components are installed to the vehicle. The information is continuously transmitted by the gateway module to make sure that the data is constantly updated and backed-up in each module.
