![]() ![]() These resistors serve as termination points. ![]() The two parallel bus wires are called CCD Positive (+) and CCD Negative (-) and they are tied together with either one or two 120-ohm resistors that reside separately inside one or two modules on the bus. The bus is a two-wire, twisted pair parallel configuration with all modules joined to the bus in a parallel circuit. The CCD bus consists of "CCD chips," which are inside the various control modules on the bus. The CCD bus was first installed in 1988 and was phased out slowly beginning in 1998. The first network protocol is Chrysler's Chrysler Collision Detection (CCD) Multiplex bus.
