This guide will show you how to use the Launch X431 device<\/a> to reset airbag crash data for Tesla Model S. The function is used to reset airbag crash data in order to recycle the airbag ECU (Electrical Control Unit).<\/p>\n

\"\"<\/p>\n

Note:In some countries, erasing airbag crash data without changing airbag assembly is not legal. So,we highly recommend to replacing car\u2019s entire airbag assembly.<\/p>\n

\n\"\"<\/p>\n

Read airbag ECU memory, select Read EEPROM menu, when reading is done, input backup file name, select backup file storage directory, data backup is done.<\/p>\n

\"\"<\/p>\n

Input backup file name, for example \u201cModel_s_20210520\u201d<\/p>\n

\"\"<\/p>\n

Click \u201cOK\u201dto backup data.<\/p>\n

\"\"<\/p>\n

Read EEPROM and backup finished<\/p>\n

\"\"<\/p>\n

Erase crash record, go into Erase Crash Record menu, the software will run for several seconds and will automatically finish it.<\/p>\n

\"\"<\/p>\n

Re-write airbag ECU battery backup data, select \u201cWrite EEProm\u201d menu.<\/p>\n

Select backup file<\/p>\n

Click \u201cModel_s_20210520.bin\u201d to select back file<\/p>\n

\"\"<\/p>\n

Click \u201cOK\u201dbutton<\/p>\n

\"\"<\/p>\n

Edit backup data. Press [YES] to use default data. Press [Auto Set] to automatically modify value (recommended). Press [Memory Dump] to manually modify backup data.<\/p>\n

\"\"<\/p>\n

If you press [Auto Set], it will skip this procedure. Press [Memory Dump], you can manually modify backup data. Start address is where the system starts to read backup data and it can be modified manually. After entering start address, press [Confirm] to write modified data, click [Restore] to recover it to old value.<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Write Data<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Perform \u201cClear Fault Code\u201d function, and then put airbag ECU back on vehicle.<\/p>\n

\"\"<\/p>\n

If you find the above procedure is cumbersome, please click [Crash Data Resetting Automatically] menu, it will automatically perform all procedures.<\/p>\n","protected":false},"excerpt":{"rendered":"
