KESS3 increases speed and safety in the workflow dedicated to Bosch MDG1 “Locked” ECUs, introducing new BENCH protocols that can be used after the unlocking procedure.
The development covers Bosch ECUs already supported in BOOT “Unlock” 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.
The first operation is to unlock the ECU: using the Unlock Module accessory, access the ECU and perform the BOOT unlock procedure, applying the required patch.
Once this step is complete, you can connect directly to the ECU connector and work in BENCH, without having to open it again.
The benefits for everyday workshop operations:
Unlock protected ECUs directly in the workshop
Direct access in BENCH after the unlock
Complete backup of ECU contents
Greater operational continuity on latest-generation cars, LCVs, heavy-duty vehicles and tractors
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.
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 “Unlock” procedure.
