Morning All ...

Though I'd start this one to make life easier for everyone.

There's lot that goes on in our cars, most of it controlled by an electronic gizmo of some sorts, and they need to interface with other parts of the car and various other gizmos...

As such, Mercedes has various names and abbreviations for it's kit, and some of it doesn't necessarily follow with those found in 'other' makes...

So ... if you get stuck, or don't know what something stand for then take a look here - we'll add more as they crop up ...

Here's a few to get going - I'll keep updating!

SAM - Signal Aquisition Module - basically a fuse and relay box - the R171 has 2 - one at the front in the engine bay, and one at the rear in the boot (trunk)

- Controller Area Network - a two wire system used buy various devices and sensors to talk to each other - think of it like a 'mini internet' for the car

- Electronic Eontrol Unit - box of electronics that controls various things
depending on it's task

DCM - Door Control Module - one in each door

OCP - Overhead Control Panel - the one with the interior lights in it

CGW - Central GatteWay - a device on the car that's a central point of communication for a lot of the others ..

IC - Instrument Cluster

TPMS - Tire Pressure Monitoring System

PTS - Parktronics (parking sensors)

UCP - Upper Control Panel - the one under the radio.
