KTS began as the Klein-Tester-Serie for electronic control-unit diagnosis. Bosch dates the KTS 300 launch to 1988, followed by the KTS 500 in 1997, the 520/550/650 generation in 2002, and 530/540/570 in 2006. Bosch dates the 560/590 generation to 2016.
Some KTS numbers denote complete bundles rather than new vehicle interfaces. Compare the device label, order number, software licence, cables and connection protocol. Bosch currently lists the 560 and 590 as passenger-car modules in its UK range; the 465/485 and 960/980 combine those modules with a computer.
