Purpose and function in the vehicle

The presented module is dedicated to the Citroen Relay III model and is mounted in the central part of the steering wheel on the driver's side. It is responsible for initiating the airbag inflation in the event of a collision, in accordance with signals from the sensors and the safety control unit. The component's design is matched to the steering wheel geometry and the factory mounting system, which facilitates service and reduces the risk of improper fitment.

Technical characteristics and compatibility

As a part of the safety equipment group, the driver's module works with the original Citroën electrical installation, maintaining the parameters specified by the vehicle manufacturer. Using the correct module allows for maintaining:

• proper communication with the central airbag control unit,
• appropriate system response time in the event of a collision,
• consistency with factory diagnostic and service procedures.

As a result, the SRS system can be correctly diagnosed with a service tester, and potential errors related to component incompatibility are minimized.

Product condition and installation aspects

The item is offered as a used part, which allows for an economical vehicle repair while maintaining the manufacturer's original specifications. Before installation, it is recommended to verify compatibility with the specific vehicle equipment version and perform standard service procedures, such as disconnecting the power supply and checking the connectors and clock spring in the steering column.

After installing the module, it is necessary to clear any errors in the control unit and perform an SRS system test using appropriate diagnostic equipment. This allows for confirmation that the safety system is operating within the intended range.

Why choose an original Citroën module

Using an original driver's module in the Citroen Relay III ensures:

• compliance with factory safety standards – a component designed for a specific vehicle model,
• consistency with other SRS system components,
• easier diagnostics and service compared to aftermarket replacements of unknown origin.

For workshops and users, this means a more predictable repair process and the ability to maintain the vehicle in a configuration close to factory specifications.
