The Practical Realization of an Automated Diagnostic System for Diesel Powered Vehicles 760838

This paper describes a microprocessor controlled test system which has been developed by PRD Electronics to fulfill the increasing need for an automated diagnostic test system for diesel powered vehicles. The rationale for a diagnostic analyzer which fully utilizes the mechanic in the test loop and rapidly provides diagnostic information on faults which are difficult and time consuming to accurately isolate manually is set forth. The translation of these requirements into realizable hardware is fully delineated. An operational test sequence as actually implemented for the testing of several different diesel engine types is given along with a presentation of the test results.
