The Launch X431<\/a> function is used to reset the airbag crash data to recycle the airbag ECU (Electric Control Unit). (In some countries, deleting airbag crash data without replacing the airbag assembly is not legal, so we strongly recommend replacing the entire car airbag assembly).<\/p>\n

This article is a step-by-step guide on how to reset airbag crash data for Tesla model X by Launch X431 device. And more repair guide for Tesla, please refer to Tesla Trouble Repair<\/a>.<\/p>\n

\"\"<\/p>\n

Preparations:<\/strong>
\nLaunch X431 V Pro<\/a> or Launch X431 PAD V<\/a><\/p>\n

Procedures:<\/strong><\/p>\n

Remove airbag ECU from vehicle<\/p>\n

Go into Tesla software, select \u201cModel 3\u201d-> \u201cSpecial Function\u201d-> \u201cService AIRBAG\u201d,as shown in figure 1, or select \u201cModel 3\u201d-> \u201cSystem Selection\u201d\u2013> \u201cSDM Airbag\u201d-> \u201cSpecial Function\u201d, as shown in figure 2.<\/p>\n

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

Unlock airbag ECU, click\u201dUnlock EEPROM After Crash\u201d. It will finish automatically.<\/p>\n

\"\"<\/p>\n

Read airbag ECU memory, select \u201cRead EEProm\u201dmenu, 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_X_20210520\u201d<\/p>\n

\"\"<\/p>\n

Click \u201cOK\u201dto backup data\uff1b<\/p>\n

\"\"<\/p>\n

Read EEPROM and backup finished\uff1b<\/p>\n

\"\"<\/p>\n

Erase crash data, go into [Erase Crash -Direct]menu, select [Read EEProm] backup file. The software will automatically perform [Write EEProm] to write backup data and verify if data written is correct.<\/p>\n

Select backup file<\/p>\n

Click \u201cModel_X_20210520.bin\u201d to select back file<\/p>\n

\"\"<\/p>\n

Edit backup data. Press\u201cYES\u201dto use default data. Press \u201cAuto Set\u201dto automatically modify value (recommended). Press \u201cMemory Dump\u201dto 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

Write data, erase airbag crash data.<\/p>\n

\"\"<\/p>\n

Verify written data<\/p>\n

\"\"<\/p>\n

Write crash data, go into\u201dWrite EEProm\u201dmenu, select backup file. The software will automatically write backup data and verify if data is correct. This procedure is similar to above mentioned procedure \u201cErase Crash -Direct\u201d.<\/p>\n

Select backup file<\/p>\n

Click \u201cModel_3_20210520.bin\u201d to select back file<\/p>\n

\"\"<\/p>\n

Edit backup data. Press\u201cYES\u201dto use default data. Press [Auto Set] to automatically modify value (recommended). Press \u201cMemory Dump\u201dto manually modify backup data.<\/p>\n

\"\"<\/p>\n

Write Data<\/p>\n

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

Verify written backup data<\/p>\n

\"\"<\/p>\n

Erase crash record, go into\u201dErase Crash Record\u201dmenu, the software will automatically finish it.<\/p>\n

\"\"<\/p>\n

Clear DTC (Diagnostic Trouble Code), put airbag ECU back. Erasing crash data is done.<\/p>\n

\"\"<\/p>\n

If you find the above procedure is cumbersome , please click \u201cCrash Data Resetting Automatically\u201dmenu, it will automatically perform all procedures.<\/p>\n","protected":false},"excerpt":{"rendered":"
