Headlamp Alignment Sensor: Testing and Inspection

Vehicle Level Sensor, Checking

The Vehicle Level Sensors transmit vehicle level in the form of a signal to the Headlamp Range Control Module J431.

In the following, it will be checked whether Left Rear Level Control System Sensor G76 and Left Front Level Control System Sensor G78 send signals
which can be evaluated to Headlamp Range Control Module J431.

In the following cases, no DTC entry is stored in Headlamp Range Control Module J431:

-

when vehicle level sensors are not installed as specified in the Repair Information

-

when vehicle level sensors are damaged mechanically

-

when vehicles have a modified axle geometry (e.g. lowered vehicle)

NOTE:  If values of vehicle level sensors are outside the tolerance range, basic setting of headlamps cannot be performed.
