WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
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 and relays the information from B-CAN to F-CAN and from F-CAN to B-CAN This is called the Gateway Function
