Level Control System Sensors, Checking

Special tools, testers and auxiliary items required

• Vehicle Diagnostic, Testing and Information System (VAS 5051B)

The Left Front Level Control System Sensor (G78) / Left Rear Level Control System Sensor (G76) transfer the vehicle inclination in the form of a signal to the Headlamp Range Control Module (J431).

There is a test to see if the Left Rear Level Control System Sensor (G76) / Left Front Level Control System Sensor (G78) deliver usable signals to the Headlamp Range Control Module.

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

• If the left front level control system sensor/left rear level control system sensor is installed incorrectly

• If there is mechanical damage to the left front level control system sensor/left rear level control system sensor

• When vehicles have a modified axle geometry (lowered vehicle).

• Headlamp basic setting cannot be performed if the values for the Left Front Level Control System Sensor (G78) / Left Rear Level Control System Sensor (G76) are outside of the tolerance.
