• เก็บสแกนเนอร์ไว้ในที่แห้งและเย็นเมื่อไม่ได้ใช้งาน
• Do not attempt to disassemble or modify the device, as this may void any potential warranty and cause damage.

การแก้ไขปัญหา

If you encounter issues with your KEVWR OBD2 scanner, consider the following troubleshooting steps:

• การเชื่อมต่อล้มเหลว:
  • Ensure the scanner is firmly plugged into the vehicle's OBD2 port and the ignition is in the "ON" position.
  • Verify Bluetooth is enabled on your device and that you are attempting to pair with "B03 HH".
  • Confirm the correct password ("1234" or "0000") is entered during Bluetooth pairing.
  • Check your OBD2 app settings to ensure Bluetooth is selected as the connection type and the correct adapter is chosen.
  • Restart your smartphone/tablet and the vehicle's ignition, then try connecting again.
• ไม่มีข้อมูลหรือการอ่านค่าไม่ถูกต้อง:
  • Ensure the app is fully connected to the vehicle's ECU.
  • Verify your vehicle is OBD2 compliant (generally 1996 and newer for gasoline vehicles in the US). Note that some older OBD-II vehicles (roughly 1996-2004) using pre-CAN protocols might not be fully supported by this device's ELM327 1.0 firmware.
  • Try a different compatible OBD2 application.
• อุปกรณ์ไม่ได้เปิดเครื่อง:
  • Ensure the scanner is correctly inserted into the OBD2 port. The vehicle's OBD2 port provides power to the device.
  • Check your vehicle's fuse for the OBD2 port if no power is detected.

If issues persist after following these steps, contact customer support for further assistance.
