- Understand Limitations: Remember that the AS100 is a basic OBD2/EOBD scanner. It excels at reading and clearing engine codes and viewing live data but does not perform advanced functions like ABS resets, airbag system diagnostics, or electronic parking brake (EPB) service functions (e.g., retracting brake calipers).
- Engine Off, Ignition On: For most diagnostic procedures, ensure the vehicle's engine is off but the ignition is in the 'ON' position.
- Clear Codes After Repair: After performing any repairs based on the diagnostic codes, use the 'Erase Codes' function to clear the DTCs and turn off the Check Engine Light. Drive the vehicle for a short period to allow monitors to reset.
- Portability: The AS100 is compact and easy to carry, making it convenient for quick checks or on-the-go diagnostics.
