Body Controller Area Network (B-CAN) and Fast Controller Area Network (F-CAN)
The body controller area network (B-CAN) and the fast controller area network (F-CAN) share information between multiple electronic control units (ECUs) B-CAN communication moves at a slower speed (125 kbps) for convenience related items and for other functions F-CAN information moves at a faster speed (500 kbps) for "real time" functions such as fuel and emissions data To allow both systems to share information, the gauge control module translates information from B-CAN to F-CAN and from F-CAN to B-CAN
