Summary:

The increasing introduction of electronic control systems in autovehicles must be implemented by the development of proper tools suitable of an easy servicing by unskilled people.Many control systems are based on the use of microprocessors because of the obtainable flexibility and accuracy in data processing. However, their use, if properly exploited, can also facilitate the method of doing the field diagnosis of the whole system.An electronic device is described in the paper that makes use of the on-board microprocessor for supplying a serial coded message containing the diagnostic information to a plug-in device which decodes and displays it by lighting-on a set of LED's.The general purpose of the device, consistently trade-named as Unitest, is obtained by servicing it with a proper set of easy-to-change plastic cards correlating each LED to a failure mode typical of the electronic control system under test
