Automotive electronic systems are becoming increasingly complex and servicing these systems is difficult and costly. These same electronics, however, when coupled with interactive diagnostic testers can provide opportunities for not only self-diagnosis but also for significantly improved overall vehicle diagnostic testing. General Motors has established a three-tiered system of diagnostic testing with Level I testing accomplished by on-board diagnostics and Levels II and III employing external test equipment utilizing a high degree of interactive diagnostic testing. A low cost handheld diagnostic tester called the TECH 1 has been developed to support Level II testing of GM vehicles by technicians in dealerships and aftermarket service centers.
