IID Tool from GAP – Safety Instructions

The IID Tool Pro from GAP is one of the most powerful diagnostic and programming systems for Land Rover vehicles available on the market. Even Land Rover diagnostic engineers tell us that the IID Tool can perform certain tasks better or easier than the original Land Rover diagnostic systems.

Even though the basic operation of the tool is very simple, there are a few things that should be considered. We will deal with these points here in this article:

The following information is provided by the manufacturer GAP for the use of the GAP tool:

1. Permanent connection of the IID tool to the car
   • The IID tool is not intended to remain permanently connected to the vehicle. It is strongly recommended to disconnect the IID Tool from the vehicle after use.
2. Performance of diagnostic tasks
   • Diagnosis is NOT programming, diagnosis is a pure reading of values, no writing of values. For programming, it is essential to observe point 5!
   • For each longer diagnostic task the engine of the vehicle should be running, because this ensures that the battery voltage is high enough for the diagnosis. Therefore a diagnosis is only recommended outdoors, with transmission in parking position or neutral.
   • Short programming tasks can be performed at your own risk even with the engine switched off.
   • However, it is generally recommended to connect the vehicle to a stable and powerful external power supply for each programming!
3. Programming with open window
   • The manufacturer recommends performing all programming tasks only when at least one vehicle window is fully open. In the event of a program abort that leads to a locking of the vehicle, an emergency exit exists, even if unlocking is no longer possible. In our experience, such cases are not known in practice, but caution is better than leniency.
4. Warning messages
   • Warning messages are displayed for some programming tasks. If this warning message appears for the first time, it may be necessary to acknowledge it three times in a row before the procedure can be continued. If the same function is used repeatedly, the number of necessary acknowledgements is reduced. By acknowledging, the user confirms that he has read and understood the warning message.
5. Execution of programming tasks
   • In order to avoid an undersupply of the control units with electrical voltage, it is strongly recommended to carry out programming only with external power supply.
   • A normal battery charger is not a powerful external power supply! The charging current should be at least 25A or better!
   • In case of emergency, programming can be done with the engine running, but for some programming tasks it is necessary to switch off the engine (sometimes several times in a row). This is shown by the IID tool during the programming process and also automatically switches off the motor (on models newer than 2010). This option should therefore only be used in an emergency.
   • An alternative possibility for external power supply is to connect the battery to a second vehicle with jump leads. In this case the engine of the second vehicle should be running during programming.
