	A SAM (Signal Acquisition Module) functions much as a network router does on a computer or communications network. It monitors input from various switches, controls, monitoring devices, and warning systems. When you push a button on, for example, your dashboard, the signal goes through a SAM before the device you are controlling responds. If there is something wrong with the device you are trying to operate, you will likely then get a warning, delivered through the SAM to the CAN (Controller Area Network) bus.

			The W220 has a host of Control Units/Modules also known as Electronic Control Modules (ECM) which communicate digitally with each other via the [[WIS 54.00 General\|CAN (Controller Area Network)]] Bus.

			Information from CAN C - Engine CAN can be sent to control modules on the CAN B - Interior CAN or vice versa via the Electronic Ignition Switch (EIS). The EIS is the only control module that can transfer the messages and is known as the gateway.

			All the Control Units/Modules are connected in a parallel circuit via a two wire, bi-directional communication link (the Bus) with data transmitted according to priority.

			The Control Units/Modules have been designed with in-built monitoring functions which whenever parameters exceed acceptable limits will produce Warning Messages on the Instrument Cluster and store relevant Fault Error Codes or Diagnostic Trouble Codes (DTC) in the vehicle memory. These DTC may be monitored using the [[http://w220.ee/STAR_Diagnosis_System_(SDS)_or_Diagnosis_Assistance_System_(DAS) STAR]] Diagnosis System (SDS). In addition to On-Board Diagnosis (OBD) STAR can perform comprehensive system diagnosis on all vehicle systems via the Control Units/Modules for engine control, suspension, audio systems, climate control etc.

			==Types of Control Units/Modules:==
			* CCM Multi-function Control Module
			* DAM (FBM) Drive Authorization Module
			* DCM Door Control Module
			* EIS (EZS) Electronic Ignition Switch Control Module
			* ESCM (MAS) Engine Systems Control Module
			* ESM (EWM) Electronic Selector Lever Module
			* GRM (GEM) Gear Recognition Module
			* SAM Signal Acquisition / Actuation Module
			* SCM (MRM) Steering Column Module
			* SIM Subscriber Identification Module
			* SVCM (MSS) Special Vehicle Multi-function Control Module
