General Information
Vehicles with level control and/or gas discharge lamps have

range control system need information about compression travel
or rebound travel at the front and rear axles.

is transferred via a connecting link to the Left Front Level Control
System Sensor - G78- and Right Front Level Control Sensor -
G289- . This transmit electrical signals to the Left HID Headlamp
Control Module - J343- / Right HID Headlamp Control Module -
J344- .

Control Module - J343- , servicing ⇒ Rep. Gr. 94 .

tem Sensor - G76- and Right Rear Level Control System Sensor
- G77- are transmitted to the Right HID Headlamp Control Module
