Module 79 - Mitsubishi CAN, bus Bootloader

Direct connection to the ECU connector is required for operation!

Caption:

• RD: Read
• WR: Write
• CK: Checksum correction

Supported ECU

• CAN-bus Bootloader FLASH (MH8114F/MH8115F/MH8501F) [RD/WR/CK]
• CAN-bus Bootloader FLASH (MH8601F/MH8610F/MH8611F/1N83M) [RD/WR/CK]

The module is designed for service mode operations with Mitsubishi ECUs that use MH8115F, MH8501F, MH8601F, MH8611F, and 1N83M processors. It supports reading, writing, checksum correction (for the listed ECUs), FLASH memory operations, and reading/writing the processor’s built-in EEPROM (D-Flash). Below is the current list of supported ECUs with their corresponding processor families:

Mitsubishi

• Outlander 3, ASX, Pajero Sport – MH8115F (D-Flash in the ECU is not used)
• Eclipse Cross 1.5T – MH8601F
• Expander, Eclipse Cross 2.0L – MH8611F (not tested)

Mazda

• SkyActiv-G Gen 3 – MH8501F (D-Flash in the ECU is not used)
• SkyActiv-G Gen 4 – 1N83M

Suzuki

• MR41S – MH8115F
• MH55S – MH8610F

Subaru

• CVT – 1N83M

Important: The operation is only possible on Bench Mode with power management, including manual control, but it is recommended to use an automatic setup. Cables for Scanmatik 2, Powerbox for PCMflash, and modified KESS boxes are suitable. control is typically done via the K-Line.

We’d like to highlight the issue with EEPROM. The D-Flash of certain processors can have a third state “erased” and Mitsubishi does not have any special mechanisms for handling such cells. When reading them, the dump will contain garbage data, and when writing, this garbage will be written into the memory. Limited testing has shown that this does not affect functionality, but it raises significant concerns for me. We do not recommend experimenting with EEPROM!
