Purpose and function of the SAM module

The rear SAM control module with an integrated fuse box has been designed specifically for Mercedes C-Class W203 and CLK C209 models. Its task is to manage and protect selected electrical circuits located in the rear of the body, such as lighting, specific comfort features, or additional power consumers, depending on the specific vehicle configuration.

Its location in the rear zone of the car reduces the length of wiring harnesses, improves the clarity of the installation, and facilitates diagnostics. As a result, replacing or servicing the module is more predictable, and the risk of installation errors is lower.

Construction and technical advantages

The SAM module combines the function of a fuse box and an electronic control unit in one housing, which allows for:

• centralization of electrical protection in the rear of the vehicle,
• organized circuit routing with clearly separated power paths,
• easier service access to fuses and connectors,
• preservation of the factory architecture of the Mercedes electrical system.

The original OEM design ensures proper fitment to wiring harnesses, brackets, and mounting points in the body, which minimizes the risk of looseness, wire tension, or poor electrical contact. This is particularly important for components responsible for power protection and distribution.

Vehicle placement and installation aspects

The presented module is intended for installation in the rear of the vehicle, in accordance with the factory Mercedes installation design. This placement:

• shortens wire lengths to rear consumers,
• facilitates the location of potential faults in the rear body area,
• allows for convenient access to fuses during inspections and repairs.

When replacing, it is recommended to maintain the sequence and position of fuses and connectors in accordance with the service documentation for the given model. This allows the module to work consistently with other vehicle control units without the need to interfere with the factory wiring.

Application in Mercedes vehicles

The SAM module with rear fuse box has been developed with the specific electrical requirements of Mercedes C-Class W203 and CLK C209 models in mind. Using an original solution from the same design family allows you to:

• maintain the consistency of the electrical protection system,
• preserve compatibility with the existing vehicle network architecture,
• reduce the risk of communication issues between control units.

For workshops and users, this means predictable installation and easier diagnostics in the future, without the need to adapt universal solutions.

Product condition and benefits of choosing a used part

The item is offered as a used part, which is a reasonable compromise between repair costs and maintaining original build quality. Choosing such a solution allows for an economical repair of the electrical system while using a component that complies with Mercedes factory specifications.
