A question before ordering?An MFT Dev engineer checks the right configuration for your vehicles with you.
Ask an engineerThe OBDSTAR MT502 is a bench test platform for electric air conditioning compressors, the ones fitted to hybrids and EVs. Most of these compressors only run when the climate control ECU orders them to, over the CAN bus: the MT502 sends that command. You check that a compressor works before replacing it, or after repair, without the vehicle.

🔌 What you do with the MT502
Electric compressor test
Bench start of the compressor, to find out whether the fault comes from the compressor or from the vehicle before ordering the part.
Guided search
By brand, model, part number, compressor manufacturer or ECU processor, with the connection guide.
Audi and Mercedes 48 V
Test of 48 V batteries and DC-DC converters on Audi A8L and Mercedes (chassis 166, 205, 206, 213, 223), and of the Audi A8L 48 V starter-alternator, with the dedicated cables T001, T002 and T003, sold separately.

🧰 Which tools does it work with?
The MT502 works on its own: tablet, low-voltage harnesses and high-voltage cables are in the box. According to the official OBDSTAR lists, the “Test platform” activation of the Key Master G3 does not include compressors: it covers clusters, climate control panels, gear selectors, ABS, head units and 48 V.
Good to know: the list is mainly Chinese. In Europe, it covers Tesla, Volvo, BMW, Mercedes-Benz, Volkswagen Touareg and Porsche Taycan: check your compressor’s part number before you order. Work on high-voltage components: qualified technicians only. The MT502 does not handle clusters or climate control panels: that is the job of the MT501.
