Note:

Calibration of the level sensor should be performed when:

Test prerequisites:

Procedure:

  1. Make sure that the vehicle is not loaded.

  2. Applies to all trucks with bogies.

    • Put the bogie switch in position 2, 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 picturers below.

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

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

  9. Calibration shall be performed with the control box operating button in the upper position, "MAN1".

  10. Perform calibration.

  11. Turn off ECS and remove the spacers.
