3. Setup and Connection
Follow these steps to properly connect the PerGar SRS Reset Scanner to your vehicle:
- Prepare the Vehicle: Ensure the vehicle's ignition key is turned to the "ON" position, but do not start the engine. The engine must remain off during the diagnostic process.
- Locate Diagnostic Port: Identify the diagnostic port in your vehicle.
- For newer BMW models (typically post-2000), this is usually a 16-pin OBD-II port located under the dashboard, near the steering column.
- For older BMW models (typically pre-2000), this may be a round 20-pin diagnostic port, often found under the hood or in the engine bay.
- Connect the Tool: Plug the appropriate diagnostic cable from the PerGar SRS Reset Scanner into your vehicle's diagnostic port.

The primary functions of this tool are to read and clear SRS airbag fault codes. Use the "ENTER" button to select from the available functions displayed on the screen.
- Reading Airbag Faults:
Once the tool is powered on and connected, it will typically display options. Use the "SCROLL" button (if available, or if the device cycles through options automatically) to navigate to the "Read Airbag Faults" option. Press "ENTER" to view any stored SRS fault codes. These codes can help identify the specific issue with the SRS system.
- Clearing Airbag Light/Faults:
After addressing any underlying issues that caused the SRS fault, or if you wish to attempt to clear the light, navigate to the "Clear Airbag Light/Faults" option using the "SCROLL" button. Press "ENTER" to initiate the clearing process. The airbag warning light on your dashboard should extinguish if the fault has been successfully cleared and no active issues remain.
Note: Clearing the fault codes does not repair the underlying problem. If the fault persists or reappears, further diagnosis and repair by a qualified technician are recommended.
5. Maintenance
To ensure the longevity and reliable performance of your PerGar SRS Reset Scanner, follow these maintenance guidelines:
- Cleaning: Wipe the device with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing or internal components.
- Storage: Store the scanner in a cool, dry place, away from direct sunlight, extreme temperatures, and excessive humidity. Keep it in its original packaging or a protective case when not in use to prevent physical damage.
