Tesla Delphi airbag module on the bench: EEPROM reading with CB106 and crash data clearing with a PCB jumper

Tesla Delphi airbag modules are worked on the bench: you can read the EEPROM and clear the crash data. Reading is done by connecting the module to the AVDI with the CB106 cable and an external power supply; clearing the crash data requires a jumper across two points on the circuit board.

Procedure

1. Remove the Delphi airbag module from the vehicle and take it to the bench: the Delphi functions (EEPROM reading and crash data clearing) are only carried out off the car.
2. Get the CB106 cable (the Abrites OBDII cable for the AVDI) and a regulated external power supply ready.
3. Connect B+ of the Delphi airbag module to B+ of the external power supply.
4. Connect GND of the Delphi airbag module to GND of the external power supply.
5. Connect CAN H of the Delphi airbag module to pin 1 of the CB106 cable.
6. Connect CAN L of the Delphi airbag module to pin 9 of the CB106 cable.
7. Connect the AVDI to the PC, start the Tesla software and open "Special Functions" > "Airbag Reset", then read the Delphi module EEPROM and save the dump as a backup.
8. CRASH DATA CLEARING: open the module and jumper the two points indicated on the airbag module PCB (see the manual illustration).
9. With the jumper in place, run the DTC clearing from the software: clearing the DTCs also clears the crash data.
10. Remove the jumper and return the PCB to its original state, close the module up and refit it to the vehicle.
11. Reconnect everything on the car and check that the airbag light goes out and that the module parameters read 0 in the "Alerts" menu.
