BENCH protocols that can be used after the unlocking procedure.<\/p><p>The development covers Bosch ECUs already supported in BOOT \u201cUnlock\u201d mode: MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 HW80, MG1CS031, MD1CP006, MD1CS005 and MG1CS002, installed on a wide range of petrol and diesel applications from 2021 onwards.<\/p><p>The first operation is to unlock the ECU: using <span style=\"text-decoration: underline\"><strong><a href=\"https:\/\/www.alientech-tools.com\/en\/accessories\/unlock-module-complete-kit\/\">the Unlock Module accessory<\/a><\/strong><\/span>, access the ECU and perform the BOOT unlock procedure, applying the required patch.<br \/>Once this step is complete, you can connect directly to the ECU connector and work in BENCH, without having to open it again.<\/p><p>The benefits for everyday workshop operations:<\/p><ul><li>Unlock protected ECUs directly in the workshop<\/li><li>Direct access in BENCH after the unlock<\/li><li>Complete backup of ECU contents<\/li><li>Greater operational continuity on latest-generation cars, LCVs, heavy-duty vehicles and tractors<\/li><\/ul><p>The Unlock Module is the initial access point that enables a faster, smoother workflow for subsequent operations and allows you to independently work on some of the most in-demand Bosch MDG1 ECUs on the international market.<\/p><p>The new protocols are available to KESS3 users with CAR BENCH\/BOOT activation and an active subscription. The KESS3 Unlock Module is required to perform the BOOT \u201cUnlock\u201d procedure. <\/p><\/div><\/div><\/div><\/div><\/div><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element
