WARNING
Calibration of individual sensors should only be attempted by
experienced users. Read this section very carefully and only
undertake a calibration when the procedure is fully understood.
Serious damages can occur if the procedure is performed im-
properly! GAP Diagnostics assumes no liability for damages
or injuries incurred during use or resulting from the use of the
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 constants relative to the height sensors
mechanical positioning. Correlating these values to the measured height of each corner is part
of the calibration procedure.
•
Changes in calibration are instantaneous in the EAS ECU but the ECU may not 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 adjust the corner height.
•
The settings and changes are given in millimetres 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 centre of the wheel.
•
A metric measuring tape is recommended for proper calibration.

cle. Place the vehicle
on a flat, levelled 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 metres and back to its original position.
