Headlamp Alignment Sensor: Removal and Replacement

Level Control System Sensor

A vehicle level sensor is located at front axle ( Left Front Level Control System Sensor G78 ) and ( Left Rear Level Control System Sensor G76 ) is
located at rear axle.

The vehicle level sensors are a component of automatic headlamp range control.

The Vehicle Level Sensors transmit vehicle level in the form of a PWM signal (pulse-width modulated signal) to the Headlamp Range/Cornering Lamp
Control Module J745.

In order to generate this PWM-signal, voltage is supplied to Left Rear Level Control System Sensor G76 via two positive wires and one Ground (GND)
wire. Voltage is supplied to Left Front Level Control System Sensor G78 via one plus-wire and two Ground (GND) wires.

Removing and installing Level Control System Sensor :

Removing and installing Left Front Level Control System Sensor G78

Removing and installing Left Rear Level Control System Sensor G76

NOTE:  If the vehicle Level sensors are replaced, headlamp basic setting must be performed.
