IIDTool
I. Getting Started
1. Introduction
IIDTool stands for Integrated Interface Diagnostic Tool. In using this diagnostic system, the vehicle’s
controls and display are used to interface with the tool.
When the firmware is completed* the IIDTool will allow complete diagnostic functionality (aside from
flashing ECUs): fault reading and clearing, viewing live data and manually activating components, and
programming / new component initialization.
* Full functionality on all vehicle systems should be available by autumn 2012. Firmware upgrades are
done via the internet and USB. Full functionality in the end version may not include all functions of the
OEM T4/IDS unit; re-flashing firmware to ECU’s will not be supported.
With the firmware version 2.17 the IIDTool has full diagnostic functionality for the EAS as well as the
ability to read fault codes of all other diagnosable modules connected on the communications busses.
Live values viewing and car configuration (personalization) capabilities are included.
2. Controls
Your IIDTool needs no additional cables or power supply. The USB connector is only used when upda-
ting the tool’s firmware.

The IIDTool is controlled with the vehicle’s cruise control
switchgear.
The functions are:
1. Resume = Enter*
2. Speed + = Menu up / increase value
3. Speed - = Menu down / decrease value
4. On/Off = Back one level / Exit
*When viewing a configuration in the car configuration menu,
pressing the resume button will show the next available option

IIDTool
Faults (DTC – Diagnostic Trouble Codes) will be displayed in the standard format if available. If not
available, it will be displayed in hexadecimal format. Fault code descriptors are in plain English.
Should a fault be displayed without the plain English descriptor, please contact us at:
[email protected] .
We will provide the corresponding descriptor.
Reading the fault output
Displayed fault in the example above: 2/5 A Compressor relay fault
As the display does not have enough characters, the message is scrolled through.
2/5: Faults are displayed with the prefix showing the fault number of the total number of faults stored in
the ECU. In the example the display is showing fault number two of five total faults stored in the EAS
ECU. If the third character is a +, there are more than 10 faults stored. Scroll through the fault list using
the +/- buttons.
A: Numeric DTC diagnostic trouble code designation.
Compressor relay fault: Plain English fault descriptor. This particular fault indicates a possible defect
in the electric circuit supplying the EAS compressor.

2. Version
The IIDTool enters the top level menu at ‘Read Fault’ and displays the firmware version of the IIDTool
when the minus button is pressed.
3. Clear Fault
Specific ECU
Displays the ECU list and allows the clearing faults in one specific ECU. Scroll to the desired ECU and
press ‘Resume’to enter.All faults stored in this specific ECU will be cleared. The IIDTool automatically
exits the menu afterwards.
Clear All
Clears all faults stored in all ECU’s and exits the IIDTool. The number displayed when clearing all is not
related to the number of fault cleared but to the number of ECUs on which the faults where cleared.
4. Calibration
WARNING
The IIDTool allows changes to vehicle settings to a state outside of
the original manufacturer specification. It is the sole responsibility
of the user to choose secure settings for the applicable use of the
vehicle.
Notes:
• Different calibration values for each corner are normal – they do NOT need to be set to
the same value! These values represent arbitrary electrical values provided by the height sen-
sors. Correlating these values to the measured height of each corner is part of the calibration
procedure.
• If the values for the standard height are set too low (without raising the values for access and
motorway heights) the vehicle may reach the bump stops in access mode. If the height indi-
cator light continues blinking after the vehicle has been switched off, this can cause a battery
drain.
• The height values are given in millimeters . This does NOT correspond exactly to changes in
height at the wheel, though. Measure all values to be sure.

IIDTool
• If the values for standard height are set too high (without lowering the offroad height or with
increased offroad heights) the suspension can reach a fully extended condition in off road
mode. In this condition, there is no suspension travel. There is severe risk of damage and
the vehicle can become uncontrollable in this state! GAP Diagnostic assumes no liability
for damages occurred in using the IIDTool.
• Changes in height are instantaneous in the EAS ECU but the ECU won’t apply these changes
immediately. The EAS ECU will adjust a corner when it’s +/- 10 mm or higher than the desired
height. For example if the corner is at +9 mm, it will not correct the height.
The calibration menu provides access to the height settings of the 4 suspension modes: standard,
access, motorway, and off-road.
For baseline calibration, the standard function allows height changes to each corner individually; for
height changes it allows changes to either front, rear, or all.
The access and motorway functions allow height changes for all corners simultaneously. The offroad
function allows separate height changes to front and rear.
Adjust All
This allows changes to the height of the whole vehicle from its current calibration - all four corners
simultaneously - at standard height. It also affects the other modes as the standard mode is the refe-
rence point. For example, if standard mode is lowered by 10mm, access mode, motorway, and off-
road height will also be 10mm lower.

Range Rover L322 2002-2005
Values are changed up or down with the + / - buttons.
If two subsequent changes of -10mm are made, the vehicle will be -20mm (20mm lower) than the ori-
ginal height.

17
IIDTool
Front
Changes height of only the front axle in all modes. +10mm means the front will be 10mm higher in all
modes.
Rear
Changes height of only the rear axle in all modes. -10mm means the rear will be 10mm lower in all
modes.
Limits
The EAS ECU has internal absolute limits that limit the extent of possible height changes.
For example, if the current calibration is
Sensor Calibration height value (mm)
Front Left 157
Front Right 138
Rear Left 180
Rear Right 166
And the limits of the EAS ECU are
Sensor Limit Value (mm)
Upper Front 200
Upper Rear 200
Lower No Limits
The front can be raised by a maximum of 200 - 157 = 43 mm. The front can be lowered without a
maximum limit.
The rear can be raised by a maximum of 200 - 180 = 20 mm. The rear can be lowered without a maxi-
mum limit.
The IIDTool automatically calculates these values and allows only changes within these parameters.
Note: The maximum values for lowering and raising are found by trial and error. They will not be
the same on every vehicle.

WARNING
Calibration of individual sensors should only be attempted by expe-
rienced users. Read this section very carefully and only undertake a
calibration when the procedure is fully understood.
Serious damage can result if the procedure is performed improperly!
GAP Diagnostic assumes no liability for damages incurred through
use of the IIDTool.
Note: The values entered into the ECU vary according to sensor tolerances and settings. It is highly
unlikely that all 4 corner values will be the same. This is normal!
The settings and changes are given in millimeters but this does not correspond exactly to changes at
the wheel. Each change in height must be measured from the bottom of the wheel arch to the center
of the wheel. (as explained on the next page).
These menu items allow the calibration of the absolute value (in mm) of each height sensor. This is
necessary when height sensors or linkages are replaced or reinstalled. At a minimum, calibration can
be done on either axle, front or rear, but it is recommended that all four corners be calibrated simulta-
neously.
Steps:
1. Preparation: go to http://gap-diagnostic.com/support/downloads.html, download and print the
EAS Calibration Aid and Sample EAS Calibration Calculation. Place the vehicle on a flat,
level surface in standard mode. While small surface irregularities may not reduce the accuracy
of a calibration significantly, large irregularities can make the calibration harder to verify. The
calibration must be done outside with the engine running as the air suspension will not rise
when the engine is not running. Study these instructions and the Sample EAS Calibration
Calculation.
2. Use the IIDTool to take note of the actual calibration. Go to menu item ‘Live Value > Suepension
ECU > View Calibration’. Note down the values in the EAS Calibration Aid.

3. To prepare the vehicle for height measurements, the vehicle must first be brought to a steady
state in standard height mode. To do this, change the height to off-road using the switch on the
console. Once at off-road height (off-road LED has stopped flashing), return to standard height
and again wait for the LED to stop flashing. Move the vehicle forward 5 meters and back to its
original position.
4. Navigate the IIDTool to ‘Live Values > Suspention ECU > View Current Height’.As the driver’s
weight affects the current height, the current height must be noted from outside the vehicle.
Open the driver’s window, exit the vehicle and leave the the door open slightly. This will prevent
the EAS ECU from making adjustments while measuring. Leave the IIDTool in ‘Live Values >
Suspention ECU > View Current Height’ mode for the following steps.
5. Measure the height in millimeters of each
corner from the bottom of the wheel arch
tothe centerof thewheel.Foreachcorner
take note of the current height displayed
on the cluster LCD (from outside) just be-
fore or after taking the measurement.
Make sure the measurement of each cor-
ner is noted at the corresponding spot.
