Purpose and function in the safety system

The offered impact sensor is designed to work in Volkswagen Tiguan 5N and Sharan 7N models, where it acts as a lateral acceleration detector. Mounted on the right or left side of the body, it transmits information about the nature of the collision to the airbag controller, which allows for the sufficiently rapid initiation of the safety sequence. A properly functioning sensor is crucial for maintaining the SRS system operation logic intended by the manufacturer.

Construction and integration with vehicle electronics

The sensor belongs to the Electronic control modules and controllers group, which means it works with the vehicle's communication bus and the central safety system controller. The module's design provides a dedicated electrical connector and a mounting method adapted to the factory mounting points in the body. This ensures the correct spatial orientation of the sensor, which is necessary for the proper interpretation of acceleration signals.

Vehicle placement and mounting aspects

The element can be used on both the right and left sides, which facilitates the selection of parts during post-accident repairs or safety system service. Such a solution allows for:

• maintaining the consistency of measurement parameters on both sides of the vehicle,
• reducing the number of part variants used in a given model,
• simplifying the diagnostic and replacement process in workshop conditions.

Before installation, it is recommended to verify the module's compatibility with the vehicle and perform SRS system diagnostics using an appropriate tester to confirm the correct communication of the sensor with the installation.

Performance characteristics and advantages of use

As an element from the Volkswagen range, the sensor is matched to the electrical and software architecture of specific models, which promotes stable operation of the safety system. The main advantages include:

• factory compatibility with the airbag control system,
• maintaining the activation thresholds and measurement characteristics intended by the manufacturer,
• the possibility of use on both sides of the vehicle, which increases service flexibility.

The used condition allows for economical repair while maintaining the original design specification of the module, provided that it is correctly selected and installed.
