OBD (4G) Troubleshooting

In order to determine what issue may be preventing your device from reporting please see troubleshooting instructions below.

Please confirm that your MT-OBD is securely connected directly to the OBD port of the vehicle.

If so then please complete the following steps:

Remove the device from the OBD port for 10 seconds or longer then reconnect it directly to the port.

To test for power, with the device connected to the OBD port of the vehicle, check to make sure that the lights on the device are illuminating.

Please note that if it is not very dark near the OBD port you may need to cup your hand under the device and look for the light to reflect off the palm of your hand.

If you do not see any lights illuminating whatsoever within 10 to 30 seconds then the device has no power.

To test to see if this is an issue with the device or with the vehicle, connect the device directly to the OBD port of a different vehicle and see if any lights illuminate.

If upon connecting the device to another vehicle you still have no lights then it is likely that the problem is with the device and it would need to be evaluated to determine the cause. (If this does happen you may try a third vehicle to remove the slight chance that you have tried it in two vehicles that do not have power to the OBD port)

If upon connecting the device to another vehicle you do see lights then it is likely that the problem is with the first vehicle.

When an OBD port is not supplying power to the device the cause is usually a blown fuse. Replacing the fuse will usually fix the problem.

If you do see lights illuminating then please follow the steps below.

For devices with a serial number starting with "22":

Blue - This indicates Cellular signal. A fast flashing blue light indicates a good cell signal. No blue light indicates searching for cell signal or not connected.

Green - This indicates GPS signal. A solid green light indicates searching for GPS signal. A flashing green light indicates GPS lock.

Yellow - This indicates ignition status. A flashing yellow light means ignition off, a solid yellow light means ignition on.

For devices with a serial number starting with "D5X":

Green - This indicates Cellular signal. A fast flashing green light indicates searching for signal. A green light flashing once every 2 seconds indicates a good cell signal.

Blue - This indicates GPS signal. A fast flashing blue light indicates searching for GPS. A solid blue light indicates GPS lock. The blue light will only come on when the device has something to report.

For devices with a serial number starting with "Y6":

Yellow - This light indicates cellular signal connection. A yellow light flickering 3 times rapidly indicates Searching for Signal. A steady yellow light blinking once every second indicates Cell Lock.

Green - This indicates GPS signal. No green light means it is searching, or is not reporting right now. A flickering green light means GPS lock.

The Blue light can be ignored.
