6. Maintenance

To ensure the longevity and optimal performance of your Autel AutoLink AL549:

• Keep the device clean and free from dust and moisture. Use a soft, dry cloth for cleaning.
• Avoid dropping the device or subjecting it to strong impacts.
• Store the device in a cool, dry place when not in use.
• Do not attempt to disassemble or repair the device yourself, as this will void the warranty.

7. Troubleshooting

If you encounter issues with your AL549, refer to the following common problems and solutions:

• Device does not power on: Ensure the OBDII cable is securely connected to the vehicle's DLC and the vehicle's ignition is in the 'ON' position. Check the vehicle's battery for sufficient charge.
• Linking error: Verify that the vehicle is OBDII compliant (1996 or newer for most vehicles). Ensure the connection is secure. Try connecting to a different OBDII compliant vehicle to rule out a vehicle-specific issue.
• Codes cannot be erased: Some permanent codes may require several drive cycles to clear after the underlying issue has been resolved. If the fault persists, the underlying problem may not be fully repaired.
• ABS function not working: Confirm your vehicle's ABS system is compatible with the AL549 (OBDII compliant 12V vehicles prior to 2020).
