30 years of Bosch KTS diagnostic testers

Karlsruhe/Plochingen (Germany) - Back in 1988, Bosch KTS 300 – the first diagnostic tester – first allowed independent workshops to check electronic vehicle systems. Back then, Bosch named it KTS or “Klein-Tester-Serie”, which is German for series of small testers. The name prevailed down to the present day. Modern diagnostic testers are still called KTS. “Ever since the company was first founded, the Bosch has been a name standing for development competence, technical quality and reliability. 30 years ago, we were among the first companies also starting to meet these requirements in the field of control unit diagnostics,” Oliver Frei, Regional President Europe at Bosch Automotive Service Solutions, says thus describing the motivation driving continuous further development of KTS diagnostic testers. “We have always aimed on increasing efficiency and effectiveness of everyday work at workshops by means of our diagnostic testers and modern software. Diagnostic solutions fit for the future of workshops – that’s what’s still driving us,” Frei continues. Consequently, the 30-year success story of Bosch diagnostic testers will go on in future as well – thanks to optimized control unit diagnoses and new generations of KTS testers providing future-oriented hardware solutions.

The success story began with the “Bosch Hammer”

When the first KTS was launched, it was able to handle engine management data of cars of three different makes. But the number of control units KTS was able to test grew rapidly. By 1999, it allowed control unit diagnoses on some 120 systems of 25 different vehicle manufacturers. Accordingly, the automotive sector soon got to know KTS 300 as “Bosch Hammer” and as a synonym for engine testers. In 1999, the Bosch Esitronic workshop software, was launched on the diagnostic testers – yet another important milestone for control unit diagnostics and further development of the KTS series. Quarterly updates – at first on CD, then on DVD and today mostly online – make sure workshops are always provided up-to-date diagnostic data suitable even for latest vehicle models and control units. Nowadays, KTS diagnostic testers and Esitronic 2.0 allow workshops to perform control unit diagnoses on more than 90 000 vehicle models of more than 150 different makes.

30 years of experience and competence in control unit diagnoses

Several electronic vehicle systems used as original equipment by vehicle manufacturers around the world have been developed by Bosch engineers. Concomitant with the first electronic systems in automotive engineering, Bosch also used its high competence in the field for its test equipment. For 30 years now, Bosch has thus been in the lead in terms of control unit diagnostics. While the demands placed on technically qualified and efficient diagnoses at automotive workshops grew, Bosch continuously improved its Klein-Tester-Serie KTS (German for series of small testers) and its Esitronic workshop software. Today, KTS modules complement exhaust gas testers and vehicle system testers. They are both either integrated into a trolley housing a PC, a screen and a printer or available as part of handy tablet computers suitable for mobile use at the workshops. Using Bluetooth, Wi-Fi or LAN, they can be connected with other testers, with the workshop network or even with the Internet. In addition, they also support all common communication protocols used by electronic vehicle systems.

Future-proof hardware with PassThru and ethernet interfaces

By means of KTS 560/590, the latest generation of diagnostic testers, Bosch once again supports independent multi-brand workshops with regard to service and repair tasks on modern vehicle systems. The Euro5/6 standards place car manufacturers under the obligation to make any technical repair information available to independent workshops by means of their online portals. In order to access these online portals, a PassThru interface is needed. Already since 2009, Bosch KTS devices are PassThru-enabled and can still be used to access repair data – although with some restrictions. Current KTS 560/590 testers feature an improved PassThru interface providing workshops with a trouble-free access to data of almost all vehicle manufacturer portals. This allows independent workshops to maintain modern vehicle models and to reprogram control units. They do not have to send their customers to authorized workshops anymore in case such tasks are to be performed.

Using KTS 560/590, workshops are also well prepared for the future. The devices already include the new, Ethernet-based Diagnostics over Internet Protocol (DoIP) diagnostic interface. It allows much higher data transfer rates particularly important considering growing data volumes required, for instance, by driver assistance systems. More and more vehicle manufacturers thus use also Ethernet for diagnoses. Basic diagnoses will still be possible via CAN interface, for comprehensive diagnoses or flashing of control units, however, an Ethernet interface as the one included at the latest KTS generation will be required.
