Level Control System Sensor

Level Control System Sensor

Vehicles without level control system (air spring shock absorber)

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 plus-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:
Left Front Level Control System Sensor G78, removing and installing.

Left Rear Level Control System Sensor G76, removing and installing.

Checking Vehicle Level Sensor
Left Front Level Control System Sensor G78 and Right Front Level Control Sensor G289, checking.

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

Vehicles with level control system (air spring shock absorber)
There are two each Vehicle Level Sensors located at front axle (Left Front Level Control System Sensor G78 and Right Front Level Control Sensor G289 ) and at rear axle (Left Rear Level Control System Sensor G76 and Right Rear Level Control System Sensor G77).

The level control system sensors are a component of vehicle level control system.

The level control system sensors transmit vehicle level in the form of a signal to the Level Control System Control Module J197.

Level Control System Control Module J197 transmits this signal to the Headlamp Range/Cornering Lamp Control Module J745.

Removing and installing Level Control System Sensor:
Left Front Level Control System Sensor G78 and Right Front Level Control Sensor G289, removing and installing.

Left Rear Level Control System Sensor G76 and Right Rear Level Control System Sensor G77, removing and installing..

Checking Vehicle Level Sensor
Left Front Level Control System Sensor G78 and Right Front Level Control Sensor G289, checking.

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