# Autodiagnos Multi-Tester Pro

The Multi-Tester Pro was originally designed for a parallel interface with the vehicle’s engine management system. A variety of adapters allowed the user to tap into the major European engine management systems, between the PCM and the vehicle wiring harness. The Multi-Tester Pro saw the same input information the PCM saw. Toward the end of its development cycle, a Volvo-only module and harness were made available to the aftermarket repair industry.
