The Vehicle Level Sensors transmit the vehicle level in the form of a signal to the Headlamp Range Control Module (J745).

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.

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

• If the vehicle level sensor was not installed as specified in the Repair Information

• If the vehicle level sensors are mechanically damaged

• If changed were made to the axle geometry on the vehicle (for example, lowered vehicles)

• If the values of the level control system sensors are outside the tolerance range, a basic setting of the headlamps cannot be performed.
