This calibration resets the pressure sensors. Checking pressure gauges are connected to monitor the bellows pressure, the pressure should be approx. 0 bar when calibrating. Calibration can only be performed when the voltage value for the sensors is within the tolerance 0.5 V +/- 0.06 V. If any of the sensors is outside the tolerance, the calibration cannot be performed without replacing the failed sensor.
Note:
When calibrating pressure sensors the vehicle will be lowered completely. Therefore it is extremely important that no persons or equipment are in the area around or under the vehicle, to prevent damage or injury.
Test condition:
Ignition on, engine off.
If there is a tag axle it should be lowered.
The vehicle must stand on level ground.
Vehicle must be without load.
All power consumers disconnected.
Sensors within the tolerance 0.5 V +/- 0.06 V.
Procedure:
Start the function.
Drain the bellows completely before calibrating.
Press "OK" to perform calibration.
A dialogue box shows the calibration's results.
The function is done.
If the function fails, check the test conditions and repair any faults.
