The TESLA Airbag Reset special function gives access to customers to perform various calibrations in the airbag module of all TESLA vehicles (Model S/X and Model 3). It covers Bosch and Delphi airbag modules.

Supported functions for Bosch airbag module (requires CB027 cable)

• Airbag exchange

• Read/update data in the module (modify EEPROM)

• Clear crash data

• Change VIN

Supported functions for Delphi airbag module

• Read EEPROM (on bench)

• Clear crash data (on bench)

In order to read the EEPROM of the Delphi airbag module you will need the following connection to the Delphi airbag module through the CB106 cable of the AVDI

B+(Delphi airbag) -> B+ (external power supply)

GND (Delphi airbag) -> GND (external power supply)

CAN H (Delphi airbag) -> pin 1 (CB106 Abrites OBDII cable)

CAN L (Delphi airbag) -> pin 9 (CB106 Abrites OBDII cable)

In order to clear the crash data you will need to bridge these two point on the PCB of the airbag module and clear the DTCs:

Once you clear the DTCs , the crash data will be cleared and you can restore the PCB to its original form by removing the bridge and return the airbag module to the vehicle.
