A new industry-standard intra-vehicle communications system (SAE J1850) was the means for on-board control modules to share information with each other and to provide plug-in testers with diagnostic information. Concorde and Intrepid were the first Chrysler vehicles to use this technology. J1850 provided the following advantages over the prior communications bus technology:
New wiring features and their benefits were as follows:
Wire harness durability and freedom from BSRs was enhanced through improved routing and protection that included the following features:
Wiring capacity was enhanced through the use of resistors in series with switches on the same circuit to indicate by a voltage level which switch had been pressed. Resistive multiplexing had been added to the headlamp and dimmer switches. It was also used with the new central door locking switches, the manual HVAC control mode switch, the power lock, automatic speed control and windshield wiper switches.
