Gap Diagnostics IID Tool BT - G4

GAP Diagnostics IID Bluetooth Diagnostic Tool
G4 Model (most vehicles up to 2019 PLUS 2020+ vehicles)

This is a Gap Diagnostics G4 IID tool (G4 IIDToolBT). ( G4 = 4th Generation Tool )

The IID Tool is a powerful diagnostic system (also called a scan tool or code reader) in a small format.

The bluetooth IID tool connects to the mobile app interface on a mobile device (Apple running iOS 11 upwards and Android fitted with V4.2 transceiver and running on Android 8.0 or higher).

There are G3 and G4 models of the IID BT tool available which have different vehicle compatibility coverage - the G3 supports vehicles up to 2019 and this G4 supports most of those plus the 2020+ vehicles.

Note that the G4 tool can be used with the adaptor cable (see our other items) to make it compatible with most of the earlier models (see table in images).

Note that you can read the faults and view live data on any compatible Land Rover vehicle but the MODIFICATION is locked to one VIN number.

Technical support is available on line with GAP Diagnostics Directly - they support UK and French language support.
