418-01-2 Module Configuration 418-01-2 DESCRIPTION AND OPERATION Module Configuration œ Overview Central module configuration Previously, the modules in the vehicle have been configured with the aid of the diagnostic unit and the "Module Programming" function (Inhale/Exhale). Here, the actual status of each module is read into the diagnostic unit and then transferred into the new module. In this vehicle, a new form of module configuration is used, known as "central module configuration". Here, all the required configuration parameters are stored in the BCM (body control module) at the factory, and from there they are transmitted to the individual modules via the CAN (controller area network). The diagnostic unit is equipped with a new routine for performing the central module configuration which is used to replace or subsequently change configuration data. Instead of reading the data into the diagnostic unit as was done in the past, they are transferred directly to the relevant module by the BCM. The diagnostic unit is only needed for starting and monitoring the process. For security reasons, all the configuration data of the BCM is also stored in the instrument cluster. This means that if the BCM is replaced, the required configuration data can be read out from the instrument cluster using the diagnostic unit and transferred to the new BCM. All modules independently check configuration data for consistency, and store a DTC (diagnostic trouble code) in the event of a fault. In the event of a fault the functionality of a particular module may be restricted. When installing a new BCM, it is necessary to reprogram the keys for the radio remote control and for PATS (passive anti-theft system). The procedure here remains the same.
