MODI will not connect or the LED is dead: troubleshooting Bluetooth pairing and power problems

A checking sequence for when the phone or tablet does not detect the MODI device, cannot pair with it, or when the LED does not flash after plugging it into the OBDII port.

Procedure

1. Check the power LED: with MODI plugged into the OBDII port the LED should flash. If it is flashing, the problem is on the Bluetooth or app side.
2. Turn the phone/tablet's Bluetooth off and back on, then try "Connect" again.
3. Close and reopen the application you used last, MODI Mobile Diagnostics or VinReader.
4. If you are switching between the two apps, close the first one completely before opening the second: the two apps cannot hold the connection at the same time.
5. Restart the phone or tablet: a simple restart fixes most connectivity problems.
6. Check the internet connection: you need a stable line, switch to Wi-Fi if necessary.
7. Turn the vehicle's ignition ON: on some vehicles the OBDII port only works with the ignition on.
8. If you have a lot of paired Bluetooth devices, unpair them all and try pairing the MODI on its own.
9. If the LED does not come on at all after plugging into the OBDII port, try the device on another vehicle to work out whether the problem is the MODI or the vehicle's port.
10. If the problem persists, raise a report through the contact form: modiobd.com/contact-form/create. For the warranty (24 months on manufacturing defects), get the account verification documentation ready and pack the device securely with all its components.
