Bosch explains its diagnostic tester provides access to the latest diagnostic protocols and technologies

According to Bosch, every third independent workshop today in Europe uses Esitronic, the comprehensive workshop software from Bosch for multi-brand diagnosis on passenger cars, light commercial vehicles, trucks and off-highway vehicles.
Bosch Esitronic 2.0 is a comprehensive diagnostic software program for the maintenance, diagnosis and repairs of vehicles with more than 200,000 active users worldwide.
The software bundle covers more than 90,000 vehicles across more than 150 different brands.
Bosch explains that Esitronic eases troubleshooting requirements at the workshop by providing maintenance schedules, repair instructions and circuit diagrams.
When using Esitronic 2.0 Online, Bosch says all data and information is always up to date, without any need for time-consuming updates.
Bosch says new practical features and functions within the Esitronic software also support workshops concerning future developments and the constantly growing demands placed on diagnoses.
It says this also includes diagnostic access to Mercedes-Benz and FCA-group vehicles with vehicle electronics protected against manipulation and unauthorised access as well as the information type, “experience-based repair” (EBR).
By now, the EBR database comprises practical notes and experiences shared about more than a million common repair cases and vehicle combinations.
Moreover, the diagnostic tester KTS 250 has also been upgraded, with the new version now also including an e-mailing function easing everyday work for the mechanics using it.

Diagnosis and maintenance of protected vehicle electronics
From September 2020, all new vehicle models in Europe have been required to be equipped with secure diagnostic access in accordance with EU Regulation 2018/858.
This regulation provides for the protection of vehicle electronics against manipulation and unauthorised access.
Following FCA (Fiat Chrysler Automobiles), Mercedes-Benz AG is now, amongst others, also introducing such safety measures in a two-stage concept.
Bosch explains that by means of its update 2020/1.02, workshops using Bosch Esitronic workshop software will receive the necessary software update to perform comprehensive diagnostic, service and repair tasks without any restrictions even on Mercedes-Benz vehicles with secured diagnostic access.
In order to meet the requirements of the mentioned EU regulation, the vehicle manufacturers work on safety concepts that often include restrictions on access to the vehicle electronics.
For this purpose and as a first step, Mercedes-Benz AG is using an extension of the so-called Seed and Key procedure. This is based on a special algorithm that is required to enable the protected functions.

The mode of operation is similar to that of a Security Gateway. However, the Bosch solution does not require any registration at the vehicle-manufacturer portal.
Without unlocking, certain functions such as calibration of driver assistance systems will be blocked and future access will be restricted to ECU identification, readout of actual values as well as readout or deletion of the fault memory. Several Mercedes-Benz models produced as of the last quarter of 2019 are already equipped with Seed and Key.
Bosch explains that regular updates of Bosch Esitronic workshop software allow workshops to continue working on Mercedes-Benz vehicles protected by means of Seed and Key without any restrictions. No special access data is required, nor is registration via the vehicle manufacturer portal necessary.
For the unlocking, the workshop only needs an internet connection and a Bosch diagnostic tester of the current generation such as KTS 560, 590 or 350 (more information on these can be found further in this article) and as of mid-2020, KTS 250 will also support this function.
In the course of the year, Mercedes-Benz AG also plans to further develop its safety concept as a second step and Bosch says Esitronic users will be informed in due time.
Bosch had already prepared its workshop software for working on FCA vehicles (Fiat Chrysler Automobiles) with Security Gateway with the Service Pack 2019/03.
In this case, internet connection is used to exchange safety certificates between modern Bosch KTS diagnostic testers such as KTS 560, 590 and 350 as well as (as of end 2020) the KTS 250 and the vehicle manufacturer server, thus granting access to the vehicle electronics.
In line with the FCA regulations, each individual mechanic must register beforehand in order to obtain a fee-based license for activation. Afterwards, Esitronic can be used as usual to perform comprehensive diagnosis on protected FCA vehicles.

Experience-based repair solutions (EBR) resulting from everyday workshop business
The information type EBR has proven to be a very useful Esitronic tool for everyday workshop business.
By means of an algorithm developed by Bosch, the EBR finder searches a multitude of sources – including forums and online posts – for common technical issues and their solutions.
Experienced Bosch experts then develop practical and verified repair solutions based on the information thus obtained.
Once a workshop employee faces one of these known errors during vehicle diagnosis, Esitronic reportedly recommends a repair solution which has already proven its worth.
Users can evaluate specific repair solutions once they have used them; solutions which have proven to be particularly useful will thus receive a higher ranking.
In this manner, Bosch says workshops can benefit from the experience of Esitronic users worldwide across more than a million real cases of applications and vehicle combinations.

Sending diagnostic protocols via e-mail right from KTS 250
The modern and compact all-in-one ECU diagnostic tester Bosch KTS 250 can be used for all vehicle-diagnostic functions, both at the workshop and as a mobile solution.
The KTS 250 is a state-of-the-art ECU multifunctional tester with all the necessary tools for fault diagnostics in the workshop and on-the-move.
Equipped with Esitronic including an outstanding coverage of more than 150 vehicle brands, as well as the best Bosch VIN database, automatic VIN identification and automatic online updates, the KTS 250 ensures workshops are up-to-date and at the forefront of vehicle diagnostics.
Bosch explains it is also ready-to-use within seconds and thanks to its intuitive software interface, is extraordinarily user-friendly and now also equipped with a practical e-mailing function.
This allows, for instance, sending the protocols created at the vehicle diagnosis to a desktop computer or even right to the client. Several reports – even of different vehicles – can be attached to a single e-mail. Fixed or regular recipients can be stored, subject and message body can be adapted and modified.
The KTS 250 is not the only diagnostic tester offered in Australia by Bosch. Also available are the following:
• KTS 350 – Bosch says the mobile KTS 350 integrated diagnostic tester will maximise workshop operations today and provide future-proofed technology to benefit operations in the future. A built-in Ethernet interface achieves high-speed data transfer reportedly up to 100 times faster than previous CAN technology and with PassThru technology, users can access and reprogramme vehicle manufacturer control unit software at any time; helping technicians to improve productivity of daily workshop routines and achieve optimal diagnosis.
• KTS 560 – Bosch says the many innovative features of the KTS 560 diagnosis module will speed up workshop operations, improve accuracy and enhance potential. The module’s advanced, fully compliant PassThru interface enables easy reprogramming of vehicle manufacturer software, and the ability to run parallel diagnosis – as the module can communicate with up to three CAN and K-Line interfaces simultaneously – means faster, more productive output in the long run.
• KTS 590 – Bosch says the KTS 590 communication module ensures the most advanced ECU diagnosis for Ethernet-based (DoIP – Diagnostics over Internet Protocol) vehicle interfaces with features that will significantly enhance workshop output. With access to the latest measuring technology, technicians can efficiently test and measure all sensor and actuator signals, and quickly and effectively evaluate voltage, resistance and current. Bosch says that the KTS 590 is the most up-to-date control unit around, making it “the future-proofed choice.”
