File (CCF). In order to work on 2005-2006 vehicles, the BCM Body Control ECU software will
have to be updated.
• If the feature cannot be changed.
Some features may not work immediately after they are changed and will require the vehicle electro-
nics to shut down. L322-02, on diesel equipped vehicles, the park heating function may take up to one
week before it becomes available on your monitor when activated.
CAUTION
Changes should only be made when needed and with the full
knowledge of risks and consequences these changes may imply.
When using the IIDTool, It is considered good practice to connect a
power supply (Midtronic’s PSC-550, CTEK MXS 25 or equivalent) to
the battery, especially when writing the Car Conguration File or Re-
Flashing an ECU. This will ensure that the battery voltage is sucient.
Note: Battery chargers are not suitable due to poor line regulation.
Instructions
When entering this menu, the IIDTool will proceed with reading the CCF and individual ECU settings
(LCM and BPM, L322-02 and L322-06). The ECU list will be displayed next.
WARNING
User should not alter any safety features. User should inform
himself of the applicable regulations or laws before making any
changes susceptible of being part of a law or regulation.
