Headlamp Alignment Sensor: Description and Operation
HID Level Control System Sensor
A vehicle level sensor is located at the 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.
Level control system sensors transmit vehicle inclination in the form of a Pulse-Width Modulated (PWM) signal to the Headlamp Range/Cornering
Lamp Control Module (J745).
In order to generate this PWM signal, voltage is supplied from the left rear level control system sensor via two positive wires and one ground wire.
Voltage is supplied to the left front level control system sensor via one positive wire and two ground wires.
