The Snap-on Pass Thru Pro III, No. EETA113C, offers automatic access to an updated reprogramming toolbox, now supporting Windows 8. The Pass Thru Pro III includes protocols for fault tolerant CAN, CAN lines and access to additional late-model vehicle networks. The device allows automatic firmware updates via USB as a vehicle connection is no longer required for firmware updates. It allows technicians to update software/firmware in the vehicle’s electronic control unit with software directly from the OEMs, fixing software-controlled drivability and emission issues. The device also can program emission-related ECUs on any J2534-compliant vehicle 2004-newer and other J2534 complaint controllers.
