Function and Role of the Impact Sensor in the Discovery Sport L550

The impact sensor mounted in the rear of the vehicle is responsible for detecting overloads and collisions in the rear body area. Based on the signal from this component, the safety system decides on the activation of appropriate protective subsystems, which is crucial for passenger protection in rear-end collisions.

The presented sensor is designed for operation on the right or left side of the vehicle's rear zone, facilitating its use in various installation configurations. This allows the service center to flexibly adapt the component to the specific installation location in the body.

Compatibility, Installation, and Integration with Electronics

As a component dedicated to the Land Rover brand, the sensor has been designed to work with the factory electronic architecture of the Discovery Sport L550. The appropriate signal characteristics and communication method with control modules ensure consistency with the vehicle's original safety system.

The vehicle placement includes the rear body on the right or left side, which is important when planning post-accident repairs and verifying correct installation. Proper seating of the sensor in its designated structural point is key for accurate overload readings and reliable operation of the entire system.

Product Characteristics and Condition

The offered component belongs to the Electronic Control Units and Controllers group, meaning it is part of the system responsible for processing and transmitting signals within the safety systems. The product is marked as used, which in practice means it comes from dismantling and is intended for further operation after correct installation and configuration in the vehicle.

Choosing an original, used impact sensor is a solution that maintains consistency with the factory electrical installation while limiting repair costs compared to purchasing a new component. For many users and workshops, this is a sensible compromise between quality and service budget.

Practical Tips for Selection and Operation

When selecting an impact sensor for the Discovery Sport L550, it is worth paying attention to compatibility with the OEM part number and interchangeable numbers – this helps avoid compatibility issues and errors in the vehicle's diagnostic system. It is also helpful to check the vehicle placement to match the component to the correct side of the rear body.
