Mercedes-Benz AG, among others, is introducing safety measures in a two-stage concept to protect vehicles from unauthorised access in accordance with EU Regulation 2018/858, Bosch reports.
Workshops using Bosch Esitronic workshop software will get the necessary software update (2020/1.02) to perform comprehensive diagnostic, service and repair tasks without any restrictions on Mercedes-Benz vehicles with secured diagnostic access.
A Bosch spokesperson said: “In order to meet the requirements of the 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’.
Regular updates of Bosch Esitronic workshop software allow workshops to continue working on Mercedes-Benz vehicles protected by means of ‘seed and key’ without restriction.
For the unlocking, workshops just need an internet connection and a Bosch diagnostic tester of the current generation such as KTS 560, 590 or 350.
From mid 2020, KTS 250 will also support this function.
The spokesperson added: “In the course of the year, Mercedes-Benz AG plans to further develop its safety concept as a second step.
“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 of end 2020 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. A
“fterwards, Esitronic can be used as usual to perform comprehensive diagnosis on protected FCA vehicles.”
