OBDSTAR P50 | Crash Data Programmer

Diagnostic Functions

The P50 offers advanced features for reading and editing SRS modules after a crash. The functions below form the foundation for restoring airbag modules.

• ECU Info: Read identification data and version numbers from the connected SRS module.
• Read DTC: Read stored fault codes in the airbag module following a collision.
• Erase DTC: Clear fault codes after performing the crash data reset.
• Read EEPROM: Read EEPROM data from the SRS module for backup and analysis.
• Write EEPROM: Write modified EEPROM data back to the airbag module.
• Read FLASH: Reading FLASH memory from the SRS module.
• Write FLASH: Writing data to the module's FLASH memory.
• Erase Crash: Clearing crash data from the airbag module so it can be reused.
• Write VIN: Programming the vehicle identification number to the module after reset or replacement.

Key and EEPROM Functions

For work on EEPROM and FLASH memory of SRS modules, the P50 supports the following functions. These are designed for reading and editing memory data for airbag crash data reset.

• Read EEPROM: Reading EEPROM memory from the SRS module.
• Write EEPROM: Writing custom EEPROM data back to the module.
• Read FLASH: Reading FLASH memory from the airbag module.
• Write FLASH: Writing edited FLASH data to the module.

Service and Maintenance Functions

The P50 supports multiple service and maintenance functions for airbag and related systems. Available functions may vary by vehicle make, model, and year.

Brake and Stability Systems

• SAS reset: Calibrating the steering angle sensor after steering system work or SRS-related procedures.

Electrical and Safety Systems

• Airbag crash data reset: Clearing crash data from the SRS module after a collision, allowing the module to function normally again.
• Battery reset (MVBM): Registering a replaced battery in the battery management system.

Special Functions and Features

In addition to standard reset functions, the P50 offers several tools that speed up and simplify work on SRS modules.

• One-click airbag reset: Performing complete crash data reset with a single command, without manual intermediate steps.
• Fuzzy search for ECU part numbers: Searching by partial part numbers to quickly find the correct procedure within the database of 16,600+ ECUs.
• BENCH mode wiring diagrams: Built-in schematics showing connections for working on removed SRS modules on the workbench.
• Comprehensive fault code descriptions: Complete description files for fault codes related to airbag and SRS systems.
