The factory shop manuals for the Dodge Caravan clearly indicate that the various
computers in the car are communicating over some sort of serial bus.  It seems
to use a bidirectional differential line.

Does anyone know exactly how that is done?  Is it RS-485 or something similar?
Is there a master computer that sends out request and command packets to the
others, or an Ethernet-like collision system?
