 +====== Function ======
  
 +The term "​vehicle'​s configuration",​ also known as CCC (Central Car Configuration),​ refers to all equipment dependent settings and operating mode configurations stored in the BCM. This includes features such as the "LED daylight running lights",​ "​auxiliary heating",​ "​automatic transmissions",​ or country specific settings such as display language and the unit system (miles/​kilometers),​ as well as user dependent or selectable configurations (like the belt minder).
 +
 +All the settings together form a sort of file that contains the complete vehicle'​s configuration. This "​file"​ is stored in the BCM's flash memory using a programming adapter and specific software, and has a backup copy in the instrument cluster (IPC).
 +
 +== CCC contents broadcasted over the CAN bus ==
 +
 +The vehicle'​s configuration is permanently retransmitted by the BCM over the HS and MS CAN buses. The IPC will forward these messages over the MM CAN bus, since the BCM is not connected to this bus. The different vehicle modules will receive this data, derive relevant data for their function and adjust it accordingly. The advantage of the central configuration is that is no longer necessary to program each of the vehicle'​s modules separately.
 +
 +== As-built CCC contents ==
 +
 +The CCC is set and programmed in the vehicle during its production. However, anyone can change it afterwards with the appropriate tools. In most circumstances,​ this is never necessary or advisable, since the majority of settings will require the corresponding components to be installed in the vehicle. As an example, a manual transmission vehicle will not turn into automatic just by setting the corresponding field in the CCC.
 +
 +However, there are parameters that can modify the behavior of existing components. The best example of this is probably the factory installed, fuel-fired heater installed in most 2.2l Diesel vehicles. This can be reconfigured in the CCC to operate as a full fledged parking heater with programmable switching times.
 +
 +== Safety first - First, make a backup of the current contents of the CCC ==
 +
 +Before trying anything, **it shall be noted, that incorrect configuration settings, failures during programming and/or inappropriate programming tools (HW, SW), can quickly turn your vehicle into a nicely painted brick!!!**. It is strongly recommended to read the configuration from the BCM **before** any modification is performed and save it as a file in a computer or USB stick.
 +
 +In case the worst has happened and no backup of the CCC was made, there are still to options to revert the situation. The first is a publicly accessible website hosted by Ford Motorcraft, where the factory settings for a vehicle can be downloaded in the form of an as-built CCC file, by entering the vehicle'​s VIN number (there is even a direct download button in [[artikel:​elmconfig:​start|ELMconfig]]). The downloaded file can then be edited in a text editor to convert it to a format compatible with ELMConfig.
 +
 +== Modification and Programming Software ==
 +
 +Instead of directly modifying bits and bytes in the CCC file, it is easier to use a CCC editor. Problably, the best editor for the Mondeo is "​[[artikel:​elmconfig:​start|ELMconfig]]"​. With this software and an ELM327 compatible programming adapter, the contents of the CCC can be easily read from the BCM and displayed in human-readable form. Also, the modified CCC can then be written back to the BCM with this software.
