What is the Sam on Mercedes?
SAM stands for Signal Acquisition Module. A SAM module (also called Signal Actuation Module) receives data from sensors, switches, and controllers, and can send data, actuate (activate) components and monitor systems. Mercedes-Benz has been using SAM modules since the mid-90s.
CAN communication in Mercedes?
CAN is a pair of wires linking control modules throughout the car. Signals are multiplexed onto this pair of wires to enable communication between modules. A CAN bus failure will mean modules are unable to communicate and may not function.
