# Fiat Ducato X250: decoding the body CAN bus

> The Fiat Ducato X250 WiCAN project decodes the 2009 vehicle's 50 kbit/s body-CAN messages into speed, RPM, lights, doors and other signals. It preserves five captures, a CAN ID reference, a Python decoder and listen-only WiCAN filters that publish values to Home Assistant over MQTT. The author reports checking signals against vehicle controls and instruments.
