1 Introduction
1.1 IIDTool objectives
The IIDTool was designed to achieve four objectives in order to meet the demands of Land Rover and
Jaguar owners for autonomy in their e󰀨orts.
• Diagnose mechanical problems or malfunctions resulting from electrical / electronic problems
• Participate in the repair process to be more e󰀩cient and timely
• Customize certain vehicle components
• Administer ECUs of the vehicle, including updating
Note: The IIDTool is not a repair tool, but can help identify the cause of a problem. Achieving the
Objectives is done by using IIDTool functions (section 1.4 and section 4) in a dened sequence (see
section 3).
1.2 Description of each IIDTool models
IIDTool (regular, discontinued)
Short for “Integrated Interface Diagnostic Tool”. A diagnostic tool using an integrated interface, soli-
citing vehicle components for display and control. Please consult version 33 of the user manual if
using this IIDTool regular. This tool is not covered by this user manual.
IIDTool BT
Diagnostic tool equipped with a Bluetooth Smart transceiver that can be used in conjunction with a
mobile device such as a tablet or smartphone.
IIDTool Pro
Diagnostic tool designed for professionals. Also equipped with the Bluetooth transceiver.
Note : To lighten the text of this manual, the term IIDTool will be used to designate the IIDTool BT and
IIDTool Pro when no distinction applies.
The following diminutives are used in this document to separate items that are either related to
the integrated interface II or exclusive to IIDTool BT or IIDTool Pro.
II: The diminutive II indicates specic features associated with usage of the integrated interface (all
tools). This interface is now discontinued. Please consult version 33 of the user manual if using
this interface with a IIDTool regular.
BT : The diminutive BT indicates specic features associated with using an IIDTool BT.
