This article describes test diagnostic instrumentation and a communications circuit therefor that can be applied to an automotive display system and most other automotive control units. Automotive electronics designers are using numerous microprocessor-based electronic units in automobiles, trucks, buses, etc., to provide control functions related to the engine, body controls, air conditioning and ventilation, remote radio and entertainment, mobile telephones, maintenance logging, navigation, etc. A microprocessor- based display system is frequently an integral part of these systems providing the control center for the driver/operator to input commands and monitor operation. Testing the display system requires duplicating or simulating the various other electronic assemblies and the operator.
