What do the lights on my device mean?


The indicator lights on your Fleetr OBD-II device show the current connection and GPS status of the device.

After plugging the device into your vehicle’s OBD-II port and turning the vehicle on, the indicator lights should begin blinking within approximately 30 seconds.

Below is an explanation of what each light pattern means and what you should do if you see it.

No Blinking Lights

If none of the indicator lights are blinking after approximately 30 seconds, the device may not be receiving power.

First, make sure the device is firmly and completely plugged into the vehicle’s OBD-II port and that the vehicle is turned on.

If there are still no lights:

  • Try unplugging the device and firmly reconnecting it.
  • Confirm that the vehicle is turned on.
  • If possible, check whether another device can receive power from the OBD-II port.

If the device still shows no lights, there may be an issue with the Fleetr device or the vehicle’s OBD-II port may not be providing power.

Please contact Fleetr Support so we can help determine whether the device or vehicle needs additional troubleshooting.

Blinking Amber and Solid Amber

This indicates that the device is attempting to establish a GPS connection.

If you see blinking and solid amber lights:

  • Make sure your vehicle is in an area with a clear view of the sky.
  • Avoid parking inside garages, under metal structures, or in areas where the vehicle is surrounded by large metal objects.
  • Move the vehicle to an open area if possible and allow the device some time to establish a GPS connection.

Blinking Green

This is the normal operating state.

A blinking green light indicates that the device has successfully connected and is communicating normally.

If you see a blinking green light, your device should be ready to transmit vehicle and location information to the Fleetr platform.

Blinking Red and Solid Red

This indicates that the device has not yet been able to establish a GPS connection.

The device may attempt to estimate the vehicle’s location using available cellular network information and communication with nearby cellular towers.

If you continue seeing red lights, try moving the vehicle to an open area with a clear view of the sky and allow the device additional time to establish a GPS connection.
