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.htm
l, download and print the
EAS Calibration Aid
and
Sample EAS Calibration Calculation
. Place the vehicle
on a fl at,
level surface
in standard mode. While small surface irregularities may not reduce the accuracy
of a calibration signifi cantly, 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
