Mercedes C117 BCM Control Unit Module Bracket Rear Right O/S A1175451140

Mercedes C117 BCM Control Unit Module Bracket Rear Right O/S is a precision component from the Brackets, mounts and assembly parts category, designed for the stable mounting of the rear right BCM control module in the vehicle body. Proper securing of electronics in this area of the vehicle affects the reliability of comfort and safety systems, which is why a correctly selected bracket is crucial for the proper operation of the installation.

Purpose and function of the bracket

The presented bracket is dedicated to installation in the rear right part of the vehicle, where it is responsible for stable and repeatable positioning of the BCM module relative to the bodywork. Correct alignment of the controller minimizes the risk of vibrations, stresses, and unwanted displacements that could affect electrical connectors and wiring harnesses. The element belongs to the assembly group responsible for:

• maintaining the control module in a fixed position relative to the body,
• limiting the transfer of vibrations from the body to the electronics,
• ensuring repeatable mounting points during service or controller replacement.

Construction and body fitment

The bracket has been developed by the vehicle manufacturer to precisely cooperate with the geometry of the rear right part of the body. Mounting holes, clips, and the shape of the load-bearing surfaces are adapted to factory mounting points, which facilitates the installation and removal of the BCM module without the need for modifications. Such fitment translates into:

• secure guidance of mounting screws and clips,
• easier maintenance of the correct routing of electrical harnesses,
• preservation of the factory logic of cable routing in the rear right zone.

Benefits of using the original bracket

Using the original holder from the Brackets, mounts and assembly parts group allows for maintaining the factory assembly architecture of the BCM module. Thanks to this:

• the risk of play and unwanted vibrations of the controller is reduced,
• the possibility of damage to connectors and wires as a result of suspension or body work is limited,
• electronics service in the rear right part of the vehicle is more predictable and repeatable. This solution is particularly beneficial for post-accident repairs, BCM module replacement, or restoring the factory configuration of the electrical installation.

Product characteristics and service application

The offered element is a Mercedes brand product, which means compliance with the factory design and assembly standards used by this brand. The bracket is intended for operation in the rear right part of the vehicle, where it must cooperate with trim elements, upholstery, and the electrical installation. In service practice, it will prove useful for, among other things:

• recreating the original BCM module mounting system after bodywork repairs,
• replacing a damaged or missing holder,
• eliminating problems with a loose controller in the rear part of the vehicle.

Technical support and parts selection
