Ride Height Sensor: Description and Operation
Level control system sensor in vehicles with automatic headlight range control - general information
4 Motion vehicles with gas discharge headlights come standard with automatic headlight range control.
The automatic headlight range control requires information about suspension compression and rebound at front and rear axles.
For this, the position of left lower link in relation to the body is transferred over a connecting link to the left front level control system sensor G78.
The sensor passes the signals onto the headlight range control, control module.
On the rear axle, the signals are passed to the control module from the left rear level control system sensor G76 .
These signals are required to determine the height of the vehicle.
The automatic headlight range control reacts automatically to changes in vehicle inclination.
The vehicle height can change in the following:
^
Towing a trailer
^
Different load conditions: Vehicle empty, vehicle partially or fully loaded
^
Slow or fast driving habits
Caution: Adjustment of headlights!
Note:
^
Checking the headlight basic setting must always be carried out when:
^
Connecting link retaining clip on link/arm has been loosened.
^
The lower link/arm was removed and installed or replaced
^
Work is performed on level control system sensor
^
The "level" sensor is replaced
