Troubleshooting Steps (Work in Order)

1. Press the Door Sensor button and watch for the LED.
2. If the LED comes on, it is a pairing issue. Email support@fleetpulse.com with a photo of the Door Sensor MAC address and the CargoView serial # plate. Hold down the button until the LED stops flashing.
3. If the LED does not come on, open the device with a tri-tip screwdriver.
4. Test the batteries for at least 3V combined.
5. If the batteries are good, gently pull up the battery tabs to make better contact with the circuit board (see photo).
6. If the batteries are bad, replace them with 2 AA lithium-ion batteries.
7. Replace the device cover and click the button to confirm LED activity. Hold the button down to ensure the LED stops flashing afterward. Email support@fleetpulse.com to verify the repair, noting the trailer ID.
