Manual Calibration (
not recommended, use the Guided instead
)
This method is discontinued but still in the tool for reference. Please use the guided calibration.
Steps:
1.
Preparation:
https://www.gap-diagnostic.com/support/documents/IIDTool/
, download and
print the
EAS Calibration Aid
and
Sample EAS Calibration Calculation
. Make sure the air
pressure in each tire (or tyre...) are within specification and that no heavy objects are in the vehi
-
cle. Place the vehicle
on a flat, leveled surface
in standard mode with wheels straight. While
small surface irregularities may not reduce calibration accuracy, 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’s not running. Study these instructions and the
Sample EAS Calibration Calculation
before proceeding.
2. 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 not
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.
3. Use the IIDTool to take note of the actual calibration. Go to menu item ‘Live Values-
>Suspension
ECU*-
>
Calibration’. Note down values in the
EAS Calibration Aid
.
4. Navigate the IIDTool to ‘Live Values-
>
Suspension*-
>
Current Height’. The driver’s weight affects
the current height values therefore they must be noted from outside the vehicle. Open the dri
-
ver’s window, exit the vehicle and close the door. After a few seconds, open the door slightly.
This will prevent the EAS ECU from making adjustments while measuring. Leave the IIDTool in
‘Live Values-
>
Suspension*-
>
Current Height’ mode for the following steps.
5. Measure the height in millimeters of each
corner from the bottom of the wheel arch
to the center of the wheel. For each corner
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.
