8.  Control I/O 
 Defi nition
The Control Input and Output menu allows testing individual components of a system. For a complete 
list of available control I/O for your vehicle, please consult the functionality list on the IIDTool’s web-
page. For example:
•  Output: Activating a suspension valve.
•  Input: Simulating an input value coming from the cabin temperature sensor to verify part of the 
HVAC system functionality.
Note: Not all ECUs allow input and/or output controlling. 
 
WARNING
Care should be taken when using the control I/O function. Make 
sure no objects or people are near any components or systems 
that will be activated.
Serious damage or injury can occur if the procedure is perfor-
med improperly! GAP Diagnostics assumes no liability for da-
mages or injuries incurred during or resulting from the use of 
the IIDTool. 
When entering this menu, the ECU list will now be displayed. The menu is navigated up and down with 
the Speed + / Menu up and Speed - / Menu down buttons. Choose an ECU and press Resume / Enter 
to select. The fi rst control input / output value for this ECU is now displayed. Scroll up and down to 
view other values and Resume / Enter to select one. In some cases the display may not have enough 
characters; the description will be scrolled through.
Notes:  
•  The IIDTool enters the ECU list at the bottom – The list is not in alphabetical order. 
•  Only the name of the value will fi rst be displayed and scrolled if necessary. After a few seconds, 
the value or status will appear on the right.
•  It is normal to see warning light(s) turning ON when controlling an input / output.
  Control Input / Output types
There are two input / output control value types:
•  Toggle value: Pressing the Resume / Enter button will change the current output or input state 
to the next available one. For example, pressing Resume / Enter while controlling a LED will 
either turn it ON or OFF depending on its current state.
•  Variable value: The messages «Select Value +/-» followed by the current value will be dis-
played. Select the desired value using the Speed + / Menu up or Speed - / Menu down buttons 
and press Resume / Enter to apply. For example, a ventilation motor can be activated at dif-
ferent speeds from 0 to 100%.

9.  Car Confi guration
 
WARNING
The IIDTool allows changing of vehicle settings to a state out-
side of the original manufacturer specifi cation. 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 recover y instruc-
tions.
 Defi nition
The car confi guration 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 
confi gurations are available for your vehicle. For example:
•  Installing a rear view camera will require a confi guration 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 ECUs allow confi guration changes. For a complete list of available car 
confi guration options, please consult the functionality list on the product page of our website. 
http://www.gap-diagnostic.com/products/iidtool.html
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.
On Land Rover Discovery 3/LR3 and Range Rover Sport, the ECUs confi gurations are stored in the 
Car Confi guration File:
The Car Confi guration File, or CCF, contains the confi guration information’s needed by all systems 
or ECUs present in the vehicle connected on the CAN networks. The Instrument Pack broadcasts 
the content of the CCF at regular intervals on the CAN networks. Each ECU knows its confi guration 
and the confi guration 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.

Notes: 
Changing a confi guration may not be suffi cient for a feature to work:
•  If the required hardware is not or still present in the vehicle.
•  If the software or hardware version of a particular system does not support the functionality. The 
3 turn fl ash feature is enabled in the Car Confi guration File (CCF). On 2005-2006 vehicles, the 
BCM Body Control ECU software will have to be updated for the feature to work.
•  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.   
 
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 or equivalent) to the battery, 
especially when writing the Car Confi guration File or Re-Flashing an 
ECU. This will ensure that the battery voltage is suffi cient.
Note: Battery chargers are not suitable due to poor line regulation.
 Use
When entering this menu, the IIDTool will proceed with reading the CCF   
. The ECU list will be displayed 
next. The menu is navigated up and down with the Speed + / Menu up and Speed - / Menu down but-
tons.
Choose an ECU and press Resume / Enter to select. The fi rst of possible confi gurations for this ECU 
is now displayed. Navigate up and down to see available confi gurations for this ECU. Press Resume / 
Enter to scroll through all available options for the current confi guration.  Once fi nished with this parti-
cular ECU, press the On-Off / Back button to get back to the ECU list.
 
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.
