Bosch supplies PassThru software for listed KTS diagnostic systems, including KTS 560 and KTS 590. Its software page also lists KTS 960/980/995 and earlier KTS models, with different software versions. Bosch’s US range includes Mastertech II. See the existing KTS directory.
Check the regional Bosch and vehicle-maker compatibility information: Bosch notes limitations for older Ford vehicles using J1850 with programming voltage.
Vehicle coverage, functions, vehicle-maker approval, operating system, driver version, subscriptions and security authorisation must be checked for the exact vehicle and job. Follow the vehicle manufacturer’s programming procedure and specified stable power supply. A J2534 interface does not by itself supply OEM software or guarantee every function.
