Level sensor calibration


Calibration of the level sensor should be performed when:

Note:

Test prerequisites:

Procedure:

  1. Make sure that the vehicle is not loaded.

  2. Only applicable to 6x2: Lower the trailing wheel axle and set the bogie in centre position.

  3. Adjust any fault codes.

  4. Block the weels and release the parking brake.

  5. Start the engine and fill the system up with compressed air until the compressor releases pressure.

  6. Raise the vehicle with the control box.

  7. Position spacers according to the picturers below.

    Front axle

    Drive axle

    • Note: Always place the spacers on both the front axle and the drive axle, irrespective of which level sensor that has been replaced.

    • Distance rear = 120 mm

    • Distance front = 280 mm

  8. Lower the vehicle onto the spacers with the control box, without draining the air bellows.

  9. Perform calibration.

  10. End diagnostic session and remove the spacers.

    • Note: During calibration the vehicle will be raised quickly to check that the level sensors have got the correct polarities.
