Module 71 - Bosch MEDC17 Bootloader

Caption:

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

Supported ECU

Direct connection to the ECU connector and a Scanmatik 2 or Scanmatik 2 Pro adapter are required for operation

• MEDC17 (TC1762/1766/1792/1796) FLASH [RD/WR/CK]
• MEDC17 (TC1762/1766/1792/1796) EEPROM [RD/WR]
• MEDC17 (TC1724/1728/1767/1782/1784/1797) FLASH [RD/WR/CK]
• MEDC17 (TC1724/1728/1767/1782/1784/1797) EEPROM [RD/WR]
• MEDC17 (TC1791/1793) FLASH [RD/WR/CK]
• MEDC17 (TC1791/1793) EEPROM [RD/WR]
• MEDC17 BSL PASSWORD [RD]
• EDC17C06 EEPROM (8KB) [RD/WR]
• EDC17CV41 EEPROM (32KB) [RD/WR]
• MEV17.2 EXT EEPROM (8KB) [RD/WR]

Explanations: 

• Flash: This is a full flash, including both internal and external flash (if present). The internal and external flash will not be read separately
• EEPROM: This is the internal EEPROM of the processor.
• BSL PASSWORD: This option is for reading the password, which can be used with Module 53. Module 71 does not require a password to work!

Sample Procedure When Using This Module

• Connect the external ECU connector with a Bench/Boot cable according to the pinout (Power, Ground, CAN bus, GPT signals) 
• Click the “Identification” button in any selection included in the module 71. Select the power management mode (as usual – using automatic). You’ll get something like this:

“Adapter: Scanmatik – SM2 USB
DLL: 1.0.0.15 (built 01.02.19)
Firmware: FW:0802 HW:02 SN:A
Module: Bosch: MEDC17 (TC1762/1766/1792/1796) FLASH

Serial number: 41808203-07C0B982-74080010-1118FB00
Hardware number: 00001820-00009101 0053C001-0055C001
ECU type: TC1797 rev. 1
Protection 1: RW W0 [00000-1FFFFF]
Protection 2: RW W0 [00000-1FFFFF]
Ext Flash: S29CD016 (2MB)
Done”

• This is the usual output, in this case this ECU is MED17.7.3.1 with TC1797 processor and 2MB external flash. Then select the correct processor type, either MEDC17 (TC1724/1728/1767/1782/1784/1797) Flash or EEPROM
• Click Read. It is recommend reading both FLASH and EEPROM when working
• It might be useful to save the processor password. In this case, regardless of the ECU type, simply select ‘Bosch: MEDC17 BSL PASSWORD’ and click Read. Again, the password is not required for the package to function. It’s only needed if BSL mode work is necessary
• Writing: Select the correct processor type and files. Click Write and everything proceeds as usual. This module supports unlocking for Module 36, Module 39, Module 66 without opening ECU

Connection option

1. Use the Bench/Boot cable for Scanmatik 2 Pro.
2. Use a high-quality PowerBox for PCMflash. Low-quality PowerBoxes are not recommended because dangerous voltage (up to +12V) can appear on the GPT pins, potentially damaging the ECU.
