Front Load Angle Sensor

%

0

100

A normal value for the front load angle sensor on an unladen car is approx. 33-40%. The actual value depends on the car's weight, chassis setting and individual sensor tolerances. The value will drop when the front suspension is compressed.

Rear Load Angle Sensor

%

0

100

A normal value for the rear load angle sensor on an unladen car is approx. 33-40%. The actual value depends on the car's weight, chassis setting and individual sensor tolerances. The value will rise when the rear suspension is compressed.

Headlamp Levelling Motor

Step

4

300

The normal position for the stepping motor on an unladen car is around 180 steps. The stepping motor is set to 180 when calibrating the AHL system and constitutes the initial value for the headlamp beam adjustment. As the car is loaded, i.e. the headlamp beam adjustment lowers the headlamp beam, this value will drop.

Calibration Value Front Load Angle Sensor

%

0

100

The value of the front load angle sensor at calibration. On an unladen car, this value should be relatively close to the value for " Front Load Angle Sensor". A major deviation can indicate that the car has been calibrated under the wrong conditions, e.g. a load in the luggage compartment. The reading must be the same for the right and left-hand AHL control modules. Deviations of a few percent are normal. Larger deviations can indicate that the AHL control modules have been calibrated incorrectly, possibly on two different occasions.

Calibration Value Rear Load Angle Sensor

%

0

100

The value of the rear load angle sensor at calibration. On an unladen car, this value should be relatively close to the value for " Rear Load Angle Sensor". A major deviation can indicate that the car has been calibrated under the wrong conditions, e.g. a load in the luggage compartment. The reading must be the same for the right and left-hand AHL control modules. Deviations of a few percent are normal. Larger deviations can indicate that the AHL control modules have been calibrated incorrectly, possibly on two different occasions.
