The new KESS3 Unlock Module allows workshops to unlock selected protected Bosch MDG1 ECUs and then program them in BOOT mode. With new KESS3 protocols and the dedicated Unlock Module, users can access ECU memories for reading, writing, and complete backup operations on supported ECUs.
Unlock Protected MDG1 ECUs Directly in the Workshop
Some newer Bosch MDG1 ECUs are protected and require an unlock procedure before their memories can be accessed.
Alientech KESS3 ECU Programmer now supports a dedicated BOOT “Unlock” procedure for the following ECUs:
- MD1CS003
- MD1CS069
- MD1CP007
- MD1CS012
- MG1CS042
- MD1CS004 (HW80)
- MG1CS031
- MD1CP006
- MD1CS005
- MG1CS002
After the ECU has been unlocked, KESS3 can access its memories in BOOT mode. This allows technicians to perform:
- ECU reading
- ECU writing
- Complete ECU backup
- Memory access for subsequent programming
The entire process can be handled in the workshop, from unlocking the ECU to programming it in BOOT mode.
