What Is This?

Found this silver box bolted down under the front passenger seat in my ML350 Special Edition.
What is it and what does it do?
One big multi-cable going in and one small single cable.
Still looking for my fiber optic amplifier so I can remove it.

Central locking
Power windows
Power sunroof
Interior lighting
Rain sensor
Headlight leveling
Alarm system
Emergency call system

The CCM is also responsible for communicating with other electronic control units in your car, such as the engine control unit, transmission control unit, and anti-lock braking system control unit.

If the CCM is not working properly, it can cause a variety of problems with your car, such as:

The central locking system may not work
The power windows and sunroof may not work
The interior lights may not work
The rain sensor may not work
The headlights may not level properly
The alarm system may not work
The emergency call system may not work

If you are experiencing any of these problems, it is important to have the CCM checked by a qualified technician.
