No data format, just the name of an airbag control unit from the manufacturer GM.
Collect raw data from EEPROM directly.
Is rather related to the engine control module (ECM) than to the airbag ECU.
There are different methdos to acquire data from airbag ECUs. Either physically from the storage systems directly (e.g. embedded forensic methods) or by using tools.
You get an .json file containg XYZ.
The PDF report contains different hexadecimal information at the end. We decoded it as follows:
| Identifier / Data blob | Example data | Description |
|---|---|---|
| F014 | 313531323837362d30302d42ffffffffffffffff | Restraint Control Module - universal |

One of the databases (CRD_l2.sqlite3) contains information about the location of specific events. The tools extracts 21 unique DPIDs. Those are: {'$7B', '$79', '$76', '$6F', '$6D', '$69', '$78', '$77', '$6A', '$70', '$74', '$7A', '$75', '$6E', '$72', '$6C', '$6B', '$68', '$73', '$71', '$67'}
For example: 'DPID $6C Bytes 4-5', None, 'DTC number for fault #4' or 'DPID $75 Byte 1', None, 'SDM Recorded Vehicle Velocity Change for Axis #1 (140 msec)', None, 'MPH'), (88, 0, 0, 0, 'DPID $75 Byte 3', None, 'SDM Recorded Vehicle Velocity Change for Axis #1 (150 msec)'.
