WARNING
The IIDTool allows changing of vehicle settings to a state out-
side of the original manufacturer specification. It is the sole
responsibility of the user to choose secure settings for the
applicable use of the vehicle.
As with any diagnostic tool, there is always a risk of failure
when writing data on an ECU. Writing the CCF should only be
done when the vehicle is not needed immediately afterwards.
Access to the internet in case support is needed is highly re-
commended. If the CCF update fails and your IIDTool can
no longer be used, please consult the recovery instruc-
tions.
4.10.1 Definition
The car configuration menu allows users to make changes, improve or upgrade software functions
supported by the vehicle. Please consult the functionality list on the IIDTool’s webpage to know which
configurations are available for your vehicle. For example:
• Installing a rear-view camera will require a configuration change in order for the image to appear
on the navigation display.
• Activate the day time running light options (DRL).
Note : Only a limited number of systems allow configuration changes. For a complete list, check out the
functionality list on the IIDTool webpage https://www.gap-diagnostic.com/support/documents/IIDTool/ .
On vehicles converted to Liquid Propane Gas or LPG, the system must be deactivated (swit -
ched to Petrol) before attempting to change the CCF, else the IIDTool will not be able to read
the CCF.

Car Configuration File
The C ar C onfiguration F ile, or CCF, contains configurations needed by all systems or ECUs present on
the CAN networks. An ECU (vehicle dependent) broadcasts the content of the CCF at regular intervals
on the CAN networks. Each ECU knows its configurations and configurations of other ECUs if needed.
Other ECUs have a backup of the CCF stored in their memory and may be used by the vehicle when
one copy is corrupted. All vehicles except the L322 2002 to 2004 use this method.
