Vehicle Multiplex Wiring — An Implementation

In order to investigate the concept of Vehicle Multiplex Wiring, a test car's wiring harness was replaced with a multiplexed system. The multiplexed system was implemented as a network of eight intelligent nodes. In addition to serving as a test bed for basic multiplex wiring experiments, the test vehicle was also used to demonstrate a number of concepts related to modular manufacturing and low cost personal computer-based diagnostics. The design, implementation, and testing of the multiplexed system are described.
