Purpose and Function of the Rear SAM Module

The described SAM module is part of the rear fuse box, responsible for managing power supply and electrical protection in the rear of the vehicle body. Its placement in the rear area of the vehicle allows for shorter wiring harnesses and a more organized installation, leading to more stable operation of lighting systems, comfort features, and other consumers powered from the rear of the vehicle.

As an original Mercedes part, the module has been designed to work with the factory electrical architecture, minimizing the risk of communication errors and compatibility issues. This is particularly important in modern vehicles where many functions are managed by an extensive network of control units.

Construction and Fitment for Mercedes W205 / W213

The Rear SAM Module in this version is structurally prepared for installation in the W205 and W213 platforms, meaning it features appropriately selected connectors, fuse socket layout, and housing geometry. This ensures a tidy installation without the need for wiring modifications or adapters.

Key fitment features:

• factory arrangement of fuse sockets and electrical connectors,
• housing adapted for the rear of the vehicle body,
• integration with the vehicle's existing wiring harness.

This solution allows for the preservation of the original protection logic and electrical system operating parameters, which is particularly important when servicing premium vehicles.

Application in the Vehicle's Electrical System

As a component from the Fuses and Fuse Boxes group, the module acts as a central power distribution point in the rear of the vehicle. It is responsible for:

• distributing voltage to individual circuits,
• protecting the installation against overload and short circuits,
• organizing electrical connections in one easily accessible location.

A properly selected and functional SAM module reduces the risk of lighting failures, power supply issues for comfort devices, and malfunctions in auxiliary systems located at the rear of the vehicle. Replacement with an original part is particularly recommended in cases of mechanical damage, signs of overheating, or contact corrosion.

Characteristics of a Used Product

The offered module is from the aftermarket, allowing for economical vehicle repair while maintaining the original manufacturer's specifications. A used component of this type is often chosen as an alternative to new parts, especially for complex electrical modules where maintaining compatibility with the factory configuration is important.

Choosing an original, used rear SAM module for the Mercedes W205 / W213 is a solution that enables the restoration of correct electrical system operation without altering the manufacturer's design. This preserves system integrity, and diagnostics and any subsequent servicing remain in line with the procedures intended for the specific model.

Part Selection and Additional Technical Information

When selecting a rear fuse box with a SAM module for a Mercedes, it is crucial to compare the part's identification data and its compatibility with the specific body version and equipment. The product has an assigned OEM part number and interchangeable numbers, which facilitates compatibility verification in service catalogs and parts selection systems.
