CAUTION
As with any diagnostic tool, there is always a risk of failure when
re-flashing an ECU. It should only be done when the vehicle is
not needed immediately afterwards. Access to the Internet is hi-
ghly recommended in case support is needed. GAP Diagnostics
assumes no liability for damages or injuries incurred during or
resulting from the use of the IIDTool. Do not do anything to the
vehicle or disconnect the IIDTool until the firmware update is fi

nished. Read the recovery instructions prior to updating an ECU.
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. This will ensure that the battery voltage is sufficient.
Note: Battery chargers are not suitable due to poor line regulation.
