Module 82 - Bosch SH725XX TCU Bootloader

Caption:

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

Direct connection to the ECU connector is required for operation!

ECUs manufactured after mid-2021 may not be supported.

Supported ECU

• Bosch SH725xx TCU (FLASH) [RD/WR/CK]

• Bosch SH725xx TCU (EEPROM) [RD/WR]

In version 1.2.5 a new module 82 “Bosch SH725xx TCU Bootloader” was added, designed to work in service mode (on the table) with Bosch transmission control units with SH725xx family microcontrollers used in ZF 8HP, VAG DQ380/381/500, MEDG17.9.8, MEG17.9.13, MEG17.9.21, TC60/80. Reading, writing, checking and correction of the KS in FLASH memory and reading and writing EEPROM are supported.

Important: BMW and JLR after the introduction of FlexRay switched to Bosch control units with Infineon Tricore microcontrollers of the Aurix family in ZF 8HP, the module does NOT work with them at all. VAG still uses SH725xx.

Direct connection to the ECU connector is required and automatic power management is highly desirable. Use “Powerbox for PCMflash” or Scanmatik cable.

Tested with Scanmatik 2/PRO, Dialink, Chipsoft, Mongoose, CarDAQ, OpenPort 2.0 (firmware update may be required).

• Bosch SH725xx TCU (FLASH) [RD/WR/CK]
• Bosch SH725xx TCU (EEPROM) [RD/WR]

ECU cloning is possible. To do this, you need to read FLASH and EEPROM from the original and write them to the donor by disabling “skipping service areas”. The operation is safe. Make sure that the processor type and boot version match! Otherwise, it will not work.

Identification example, 0D5 (AL551)

Boot: bh1i0201

Hardware number: 103442025501

MCU: R5F72568R

Flash: 4096KB

Eeprom: 128KB

Information on working with MEDG17.9.8, MEG17.9.13, MEG17.9.21 . These units have two processors on the CAN bus – motor and box. In order for the motor processor not to interfere with the work with the box in the service mode, you must enable the “Reduce exchange speed” option in the program Settings.

Regarding the operation with MEG17.9.13: The unit starts extremely unstably, and the transmission part does not always respond. It has been observed that if the engine part (main connector) is powered continuously, and the transmission part is powered through the power management circuit, then the transmission part starts to operate more stably.
