Tester for testing air conditioning compressors.
To test clutchless compressors with direct drive and external control (Zexel/Sanden/Denso) installed on modern models of BMW, Mercedes-Benz, Toyota, VAG, Fiat, Alfa Romeo, etc.
The device is an electronic device that imitates the control signal supplied to the compressor by the car's climate control system and allows you to control the compressor "directly" bypassing the standard control units.
This allows you to localize the fault with a very high degree of probability.
