The MAHLE Service Solutions ArcticPRO ACX1185 air conditioning unit offers integration of the company's TechPRO diagnostic tool to service vehicles that use R-134a refrigerant and the ArcticPRO ACX1285 unit offers TechPRO integration to service vehicles that use the new R-1234yf refrigerant. Both units offer a larger 7" LCD touch screen for ease of use. TechPRO is MAHLE’s diagnostic scan tool that features the ability to decode a VIN in one second with one click. TechPRO was engineered so the vehicle communication interface (VCI) and software can be used with a technician’s current desktop, laptop or tablet, making it unnecessary to buy or lease extra hardware.
