Tool comparison
The OBDStar P50 is a dedicated airbag/SRS reset tool. After a collision the airbag control module stores crash data and hard fault codes that keep the warning light on and block the system; the P50 reads those modules and clears the crash data so a repaired or otherwise intact module can be reused instead of replaced. It supports a large list of SRS ECU part numbers across many makes and works by direct connection to the module or through adapter and EEPROM access rather than OBD alone. Bodyshops and airbag-repair specialists use it to return SRS systems to a no-fault state after accident repair. It is part of OBDStar's tool line with regular database updates covering new airbag ECU IDs.
The Bosch Crash Data Retrieval (CDR) tool reads Event Data Recorder (EDR) information stored in a vehicle's airbag control module and related restraint systems. Investigators connect through the OBD-II port or directly to the module, and the CDR software interprets recorded parameters such as pre-crash speed, throttle, brake status, seatbelt use and airbag deployment timing. It is widely used by law-enforcement crash reconstructionists, insurers, forensic engineers and researchers, and its outputs are formatted for admissibility in many jurisdictions. Bosch maintains vehicle coverage lists specifying which makes, models and modules are supported. CDR is a read-only forensic tool for restraint and crash data; it does not tune engines, modify calibrations or reprogram powertrain ECUs.
OBDStar P50 (Airbag / Crash Data, OBDStar) and Bosch CDR (Airbag / Crash Data, Bosch) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
