In modern vehicles, the OBD-II system uses the CAN protocol as the communication backbone to gather diagnostic information from various ECUs and sensors. This integration enables standardized access to vehicle data, making it easier for technicians and diagnostic tools to communicate with the vehicle’s computer system.
Using the OBD-II port, which is typically located under the dashboard, diagnostic tools or scanners can establish a connection to the vehicle’s CAN bus. They can then retrieve diagnostic trouble codes, read live sensor data, and perform various diagnostic functions. This allows for efficient troubleshooting, maintenance, and repair procedures.
