ELECTRONIC TEST EQUIPMENT FOR THE 80'S (AUTOMOTIVE DIAGNOSTICS)

Recent electronic component developments are summarized which will enable the development of a new family of electronic automotive test equipment in the 1980's: microprocessors and associated components, display systems, voice synthesizers, and printers. Chrysler's Universal Electronic Engine Performance Analyzer (U-EEPA) is described as representative of equipment for the early 1980's. This microprocessor-based diagnostic machine executes preprogrammed test sequences, provides test results, and gives repair instructions to the mechanic. Modules to supplement U-EEPA in the 1982-1983 time frame are outlined; add-ons include testing of automatic transmission, air conditioning, emissions, and electrical equipment located outside the engine compartment. The current trend toward on-board diagnostics is mentioned, as well as the growing interest in signature analysis for diagnosing problems with digital devices. A closer interface between automotive dealerships and manufacturers for parts supply is envisioned for the mid to late 1980's. A possible configuration for the future is suggested: an integrated complex of on-board diagnostics and local off-board diagnostics with access to a central diagnostic data base. This is expected to decrease the need for failure specialists, reduce repair time, and increase customer confidence.
