The Techno Tools Corp. Mobile Air Conditioner Compressor Electronic Control Valve Tester, No. EVDC100, tests electronic control valves in variable displacement mobile air conditioner compressors. This OEM-approved tool is placed in-line between the control valve and the wiring harness connector, and the electronic control valve regulates internal compressor pressure to change the compressor displacement. The tester regulates the input signal to the valve to verify the valve's operation. Manually controlling the operation and function of the valve helps lower repair costs and service time and eliminates compressor misdiagnosis and unnecessary compressor replacement, according to the company.
