Level calibration Gen 2


When calibrating the air suspension the vehicle is going to move up and down. It is very important that neither persons or equipment are in the area around or under the vehicle's frame as squeezing injuries easily can occur.

Note:

The correct setting measurements for normal drive level can be found in the charts below.

If the drive level outside the permissible range is used the vehicle will not accept the drive level and fault codes is stored.

Test prerequisites:

Procedure:

  1. Maximum level

    • Raise the vehicle to the shock absorbers upper mechanical stop, front and rear, using the control box.

    • Calibrate the maximum level.

  2. Minimum level

    • Lower the vehicle to the shock absorbers bump stop, front and rear, using the control box. Check that the lowering is not limited, for example because of creasing of the bellows.

    • Calibrate the minimum level.

  3. Normal drive level

    • Set normal drive level, front and rear, with the control box. The correct setting measurements for normal drive level can be found in the charts below.

    • Calibrate the normal drive level.

  4. End the diagnostic session. Then turn off the ignition for at least 5 seconds to apply the new settings.

Information concerning adjustment to bellows height generation 2.

Chassis height.

There are three different chassis heights that influence the heights for calibration.

Front axle.

The front axle´s point of impact decides what bellow heights that should be chosen at front calibration.

The bellow heights at front are measured between the frame´s underside and the lower edge of the bellow´s lower roller body.

Rear axle.

The type of rear axle bridge decides which type of bellow heights to choose at calibration at the rear. Measurements on vehicles with supporting axle shall be done with the axle lowered.

Another factor that influences the calibration is the generation of the rear axle suspension.

The rear bellow height is measured between the rear axle bridge´s upside and the underside of the frame, with the supporting axle lowered.
