  • Cable Connection Problems: A loose or damaged cable is a frequent culprit.

Troubleshooting Steps When Your Autel MS906BT Will Not Communicate

Now that we’ve identified potential causes, let’s explore step-by-step solutions.

  1. Check Cable Connections: Ensure the OBD-II cable is securely connected to both the scanner and the vehicle’s OBD-II port. Try a different cable if you suspect a fault. More details on Autel cables can be found on our Autel MK808 Cable page.
  2. Verify Vehicle Compatibility: Double-check that your MS906BT is compatible with the vehicle’s make, model, and year. Consult Autel’s official website or documentation for compatibility information.
  3. Restart Both Devices: Turn off the Autel MS906BT and the vehicle’s ignition. Wait a few minutes, then turn both back on. This simple step often resolves minor software glitches.
  4. Update the MS906BT Software: Ensure your MS906BT is running the latest software version. Outdated software can cause compatibility and communication issues. You can find information on update costs on our Autel MP808TS update cost page.
  5. Check Bluetooth Connection (if applicable): If you’re using Bluetooth, ensure it’s enabled on both the scanner and your device (e.g., tablet or smartphone). Try re-pairing the devices.
  6. Check the Battery: Verify that both the MS906BT and the vehicle’s battery have sufficient charge. A low battery can disrupt communication.
