Troubleshooting FAQ
How do I create a Support troubleshooting ticket for my offline devices?
To create a troubleshooting ticket for Support:
- On the map page, select your offline device from the Tracker List and select the ‘Troubleshoot This Device’ button.

- In the Troubleshooter pop up, select the ‘Create Ticket’ button.

- Select the issue in the dropdown for the selected device or select the ‘Multiple Trackers’ button to create a ticket for multiple devices.



Selecting ‘Multiple Trackers’ will display a similar pop up with a dropdown to add additional devices.

Once you select ‘Submit,’ a confirmation pop up will appear.

NOTE: You can also create this ticket from the ‘Tracker Setup’ page. Navigate to ‘Setup’ > ‘Tracker Setup’ and select the ‘Troubleshoot’ button to prompt the Troubleshooter pop up.
Why is my device offline?
Your device is programmed to check in to the portal every minute when ignition is on and every hour when ignition is off. If the device misses two ignition off events, it will show as “offline.”
The device can go offline for a number of reasons, such as:
- The vehicle is parked in an underground parking garage or in a metal building.
- The vehicle is parked in an area with limited or no cellular network coverage.
- The device is uninstalled.
- The vehicle battery is lower than the minimum 11 volts needed for the device to operate.
- The device SIM may have been deactivated (requires Support assistance).

How do I wire this device in?
The wiring harness includes the red, white, black, yellow, orange, green, brown, and blue wires.

Red wire to Constant Power
- Used to charge the internal battery and power the device.
White wire to Switched Ignition
- When power is applied, this will cause the device to report at one minute intervals for the Asset Tracker and Vehicle profiles. When power is removed, the Asset Tracker profile will report at 24 hour intervals, the Vehicle tracker profile will report at 1 hour intervals.
Black wire to Ground
- Must be connected to complete the electrical circuit.
Yellow Wire
- PTO (secondary input) #1 on the Customer Portal.
Orange Wire
- Not used at this time.
Green Wire
- Not used at this time.
Brown Wire
- Not used at this time.
Blue Wire
- Not used at this time.
NOTE: Unused wires should be taped out of the way and prevented from making contact with anything metal.
Why is my tracking delayed in a big city?
The device is programmed to store data when it cannot connect to a cellular network or when that network connection is not strong enough to send data.
NOTE: The most common reason for a device to store data while in an area that should have a strong cell network is network prioritization, where devices including tracking devices are given lower priority on the cell network so phones and tablets have fewer network issues.
Storing and forwarding data is a critical feature allowing the device to store the trip data and forwards this data to our servers when the network connection is strong again.
What do these LED lights mean?
Blue
- Off = reboot
- Fast blinking = searching for cellular network
- Slow blinking = connected to cellular network
Green
- Solid = searching for GPS
- Blinking = GPS locked

NOTE: If the device has no lights, it is not receiving power.
Troubleshooting Steps
- Confirm the device is outside and not in a garage or under metal.
- Send the device a reset message.
- From the Map Page, select your tracker and select the ‘Troubleshoot This Device’ button.

- Once ‘Troubleshoot This Device’ has been selected, you will see a pop up window with an option to ‘Reset Tracker’ and ‘Create Ticket.’
- ‘Reset Tracker’ sends a reset message to the device, prompting it to check in and come back online.
- ‘Create Ticket’ offers a dropdown to select the problem for the selected device or select the ‘Multiple Trackers’ button to create a ticket for multiple devices.

If the device remains offline after sending a reset message, proceed with the following physical troubleshooting steps:
- Confirm the device is on top of your equipment with a direct line of sight to the sky.
- Ensure the device is wired properly according to your asset.

For Non-powered Assets:
Wire to constant power

For Powered Assets:
(Note: this is REQUIRED for Mower Tracker)

- Confirm which lights are blinking when the device is installed.
NOTE: If the device does not have lights when installed, it is not receiving power.

Blue
- Off = reboot
- Fast blinking = searching for cellular network
- Slow blinking = connected to cellular network
Green
- Solid = searching for GPS
- Blinking = GPS locked
- If the device DOES have lights when installed, connect the device to an external 12 volt battery wired red and white to power, black to ground, and place the device and battery outside overnight.
- This is the most ideal setup for the device.
- Charging the device overnight outside should bring the device back online.
- Once the device is back online, you can reinstall it on your equipment.
- If the device does NOT have lights when installed, install the device in a second wiring harness.
- If the device comes online in the second wiring harness, the original wiring harness may have a blown fuse (this 3 amp fuse can be replaced) or the wiring harness may need to be replaced.
If your device remains offline after these steps, please contact Support.
