Purpose and function of the module

The presented Mercedes X164 Third Seat Row Control Unit Power Folding Module FSSG has been designed as an integral part of the comfort system in the Mercedes X164. Its task is to handle control signals, monitor actuator operation, and communicate with other onboard modules so that the backrest folding process is smooth and safe.

The positioning in the front left side area allows for optimal routing of electrical harnesses and easier integration with the vehicle's main electrical architecture. This allows the module to respond predictably to user commands and signals from other controllers.

Construction and integration with the vehicle's electrical system

As an element from the Electronic control modules and controllers category, the Mercedes X164 Third Seat Row Control Unit Power Folding Module FSSG is based on an electronic circuit adapted for operation in an automotive environment, taking into account voltage fluctuations, temperature changes, and typical operational loads. The module housing is prepared for installation in the factory-designated location, which facilitates correct mounting and wire routing.

The module works with the original Mercedes electrical harness, which allows for maintaining the factory logic of the comfort system. Thanks to this, after correct installation, it is possible to restore or maintain the rear seat folding function without the need to interfere with the installation structure.

Service application and benefits of installation

Replacing the rear seat folding controller is recommended in situations where there are problems with the mechanism's response to commands, incomplete folding of backrests, or communication errors in the comfort system. Using a dedicated module for the Mercedes X164 allows you to:

• restore the proper operation of the rear seat folding function,
• maintain the consistency of the electrical and comfort system operation,
• minimize the risk of improper cooperation with other controllers in the vehicle.

The used element is a reasonable choice for repairs where the cost-to-functionality ratio matters, while maintaining characteristics close to the factory standard.

Compatibility and part identification

The module has been developed for use in Mercedes vehicles equipped with an electric rear seat folding system controlled by a dedicated FSSG unit. Identification is based on the OEM part number and interchangeable numbers, which facilitates the selection of the correct element for a specific vehicle configuration.

Due to its belonging to the Electronic control modules and controllers group, the module maintains compatibility with the Mercedes electrical architecture, which is crucial for correct communication in the controller network and avoiding software conflicts.

Practical installation tips

When installing the Mercedes X164 Third Seat Row Control Unit Power Folding Module FSSG, it is recommended to:

• maintain the original routing of electrical harnesses,
• check the condition of connectors and pins for corrosion or mechanical damage,
• perform a test of the seat folding function after installing the module.

This approach helps reduce the risk of recurring faults and ensures stable operation of the entire comfort system in the Mercedes X164.
