Fortunately MPPS V18 has a handy password recovery tool we can use. If, like myself, you did not back up the password then we need to recover that password from the backup file and then use it to reflash the ECU. It may well work but I cannot guarantee it as I have not tried. Module 71 you can try using that password in the PCM Flash Infinion Tricore BSL module – If you backed up the BSL password in PCM Flash using the Bosch MEDC Bootloader Module – Module 53 it refused by an incorrect password error. You will notice when we tried to read the internal flash in the Infinion Tricore BSL module – There is a bigger issue with the ECU than a bad flash. If it does not identify, This guide cannot help you. If it identifies, then we are good to go. Then try again using the Infinion Tricore BSL module – Module 53, with the grey wire – BOOT from your scanmatik cable connected to the boot pin wire you just connected. If the ECU DOES NOT identify you can try opening the ECU and soldering a wire to the boot pin. When you try to read the internal flash this will not complete and you will see an incorrect If it does identify, read the eeprom and save it just in case you need to do a full ECU clone. If it does not identify: Switch to the Infinion Tricore BSL module – Module 53 and see if the ECU If it identifies: then try to flash again as the ECU is NOT in boot mode. To test if we are still in boot mode, try to identify the ECU again using Bosch MEDC Bootloader In 99.9% of cases this usually leavesĬheck if the ECU is in bootmode and investigation: Then ends unexpectedly with an error or not completed. Using PCM Flash in the Bosch MEDC Bootloader Module – Module 71, a flash erase starts and If you did not, this guide cannot help you! Please note: This guide assumes you made a backup of the ECU software before flashing. Some bits may be in the wrong order or I have forgotten something so use a guide, not a procedure. This guide is something I have cobbled together after a brick situation occurred on a BMWĮDC17CP45 ECU whilst in boot mode. Guide on how to restore a BOSCH EDC17 ECU after a boot mode flash goes wrong with KTM Bench programmer, I have full backup with password extracted with ktm bench but ecu f flasher tell me wrong password.
