Any of the pressure sensors has been replaced.
Work has been done on any sensor.
The control unit has been replaced.
Note:
During calibration, the vehicle will be moved up and down. Therefore it is extremely important that no persons or equipment remain in the area around or under the vehicle's frame to prevent crushing injuries!
Test conditions:

The vehicle must stand on level ground.
The vehicle must be at a standstill.
No faults in the system.
Procedure:
Select the calibration function.
Lower the vehicle down to lowest level with the buttons.
