Vehicle Application and Function

The airbag impact sensor used in the Range Rover L405 and L538 models works in conjunction with the central SRS control unit. Its function is to quickly detect a sudden deceleration and transmit a signal to activate the airbags and seatbelt pretensioners, according to the algorithm stored in the control unit.

A correctly functioning sensor contributes to:

• accurate collision recognition by the passive safety system,
• reduced response time of the airbag system in the event of an accident,
• maintaining compatibility with the operating logic of the airbag control unit.

Technical Characteristics and System Integration

The presented component belongs to the group of Electronic Control Units and Controllers, meaning it communicates with the vehicle's bus system and the dedicated SRS control unit software. The sensor is factory-designed for installation at specific points on the body to accurately measure the actual accelerations acting on the car's structure.

Key features of this type of sensor include:

• dedicated activation threshold characteristics tailored to the safety system calibration in the Range Rover L405 and L538,
• communication with the control module within the vehicle's electronic architecture,
• construction designed for harsh conditions (vibrations, temperature fluctuations, humidity).

Condition, Origin, and Service Application

The offered sensor is from a Land Rover vehicle and is a used part. This type of component is often chosen as a service solution for post-accident repairs when damaged SRS system components need replacement. A correctly selected sensor allows for the restoration of proper airbag system operation after body repairs and clearing of control unit error codes.

Before installation, it is recommended to:

• verify compatibility with the specific vehicle equipment version,
• install in the original mounting location, according to service documentation,
• perform computer diagnostics after installation to confirm correct communication with the SRS module.

Benefits of Using an Original Electronic Module

Choosing an original sensor from the Land Rover Electronic Control Units and Controllers group ensures consistency with the vehicle's factory safety architecture. This allows for:

• maintained operational parameter compatibility with the airbag control unit software,
• minimized risk of SRS system errors resulting from incorrect sensor characteristics,
• predictable airbag deployment in critical situations.
