Purpose and function in the vehicle

The presented KaFAS module is mounted in the front part of the vehicle and works with driver assistance systems by analyzing road images and speed limit signs. Based on data from the camera, the controller transmits information to the onboard systems, enabling the display of the current speed limit on the instrument cluster or multimedia screen, as well as integration with speed assistant functions.

The component is dedicated to the electric BMW i3 I01 generation, which ensures proper fitment in terms of construction and logic regarding the vehicle's electrical architecture and communication buses.

Construction and integration with BMW systems

The module combines a front camera and an electronic controller responsible for image processing and communication with other units in the car into a single housing. This solution provides:

• consistent operation of sign and speed limit recognition functions,
• stable data exchange with other onboard controllers,
• preservation of the factory logic of driver assistance systems.

As an element from the Electronic control modules and controllers category, the KaFAS camera works with the vehicle's controller network, utilizing original BMW communication protocols, which facilitates diagnostics and potential coding after installation.

Benefits of using a used KaFAS module

Using a used KaFAS module in a BMW i3 I01 often allows for a significant reduction in repair costs compared to purchasing a new unit, while maintaining the manufacturer's original specifications. This solution is particularly beneficial in cases of:

• damage resulting from a collision in the front of the vehicle,
• failures of the electronics responsible for sign recognition,
• the need to restore full functionality of the speed limiter system.

The used OEM component allows for maintaining compatibility with factory software and vehicle configuration, which promotes seamless integration after proper installation and adaptation at a service center.

Selection, compatibility, and technical aspects

To ensure the proper operation of the system, the selection of the KaFAS module for the BMW i3 I01 should be based on compliance with the manufacturer's markings and the equipment configuration of the specific vehicle. In practice, this means verifying parameters in service documentation or by part numbers, as well as considering the software version with which the given control unit operates.

During installation, attention should be paid to:

• proper placement of the camera in the front zone of the vehicle,
• correct connection of the electrical harness and communication connectors,
• the potential need for camera calibration and controller coding after installation.

This approach minimizes the risk of errors in assistance systems and ensures stable operation of the speed limit recognition function.
