Level calibration air suspension
This function is used to calibrate the air suspension.
Calibration of level sensors should be performed when:
The control unit has been replaced.
Level sensors has been repaired or replaced.
The vehicle will move up and down when the air suspension is calibrated. It is therefore extremely important that no persons or equipment remain in the area around or underneath the vehicle, to prevent damage or injury.
The calibration is carried out by setting the vehicle in the correct run level, with the buttons in the function. When the vehicle is correctly set, the level sensors can be verified that they are within the tolerance level. If any of the sensors is outside the tolerance level, the sensor must be released and adjusted correctly by locking the sensors with a locking pin. The level sensor arm is adjusted so it falls within the tolerance level.
Before starting the function, make sure that the vehicle is in the following position:
Constant air supply in the system.
Parking brake not applied.
The vehicle must stand on level ground.
Make sure that the vehicle can not start to roll.
The calibration can be performed with two different height-levels (large and small).
Setpoint on the sensors is 2,50V. The calibrated values must be within 2,46V - 2,54V.
Always adjust the height of the air suspension in the same way: From rear to front axle.
Set the vehicle in the correct level by activating the valves.
Read out the sensors that they are within the tolerance (Sensors outside the tolerance level is changed by adjusting the level sensor arm to the correct tolerance level).
Chose "OK" to start calibration.
If the calibration failed, check the values of the sensors and rectify any incorrect values.
