Non-reporting device troubleshooting flowchart

A device went quiet. Follow ten steps in order: power, SIM, signal, APN, server link, platform, GNSS fix and configuration. Fix it yourself, or know exactly what to send when you replace it.

The flowchart

Yes goes down. No goes to the action.

The Word file has the same flowchart on one page, as a table you can edit, followed by the detail of each step.

Start: a device is not reporting 1 Other devices No Server side. Ask the admin. Yes 2 Power No Fuse, ground, plug, voltage Yes 3 SIM No Reseat, test, ask the carrier Yes 4 Network and signal No Antenna, coverage, roaming Yes 5 APN No Fix the APN, restart Yes 6 Server link No Address, port, protocol Yes 7 Platform registration No ID, vehicle, subscription Yes 8 GNSS fix No Sky view, antenna, wait Yes 9 Configuration No Restore a known-good setup Yes 10 Replace and escalate No Swap the unit, open a request Yes Back online. Log the cause.
Fig. 1 Ten steps. After each action, go back to the step it names and check again.
Check passes: go downCheck fails: do the actionStill silent: swap the unit
Start from the symptom

Symptoms and steps to try first
What you seeTry these steps first
Never appeared on the platform after installationSteps 3 to 7: SIM, signal, APN, server link, ID registration
Was reporting, then stopped on one vehicleSteps 2 and 3: power, SIM plan or balance
Stopped on many vehicles at the same timeStep 1: server, platform or carrier
Online, but the position is old or does not moveStep 8: GNSS antenna, mounting, sky view
Reports only in some placesSteps 4 and 5: coverage, roaming, APN for roaming
Reports for a while, then goes silentSteps 2 and 3: loose ground, low supply voltage, data plan used up
Changed the server and the device vanishedSteps 6 and 7: address, port, protocol, ID on the new platform

Why check the steps in this order?

A device sends data through a chain: power, SIM, network, data session, server, platform. If a link early in the chain is broken, nothing after it can work. Checking in order finds the cause faster and stops you changing settings that were fine.

Step 1 asks about other devices on purpose. If many devices stopped together, the problem is on the server, the platform or the carrier, and no visit to a vehicle will fix it.

What to record

Use the log on the last page. For each case write the steps you tried, the step where it failed, the cause and what fixed it. After a few weeks the log shows patterns: one carrier, one installer, one batch, one kind of vehicle.

Facts to fill in once

Page 1 has a short table for what only your device manual can tell you: what the LED shows, the supply voltage range, how to read the status, the first-fix time, the report interval, how to send a setting and who to contact. We do not guess these. Fill them in once and the flowchart becomes specific to your device.

Work safely

Disconnect before you touch wiring

Disconnect the vehicle battery before you work on the power wiring, and follow your own site and workshop rules. Never bypass a fuse.

Limits

The flowchart is a general order of checks. It does not give device commands, LED meanings, APN values or server addresses, and it cannot see inside your platform. If a step does not fit your device, follow your supplier's instructions.

Fix settings from a distance

Many of the fixes in this flowchart are settings. Tracom devices take configuration files and real-time SMS adjustments, and they update over the air, so some problems end without a visit.

  • Advanced configuration files. Keep a known-good configuration to restore.
  • Real-time SMS adjustments. Change a setting without a visit.
  • Over-the-air updates. Update device software without a workshop visit.
  • SCMS portal. Manage devices and configuration files in one place.
Questions

Troubleshooting questions, answered

A device you cannot bring back? Talk to Tracom.

Does it work for any GPS tracker?

Yes. The order of checks is general. You add the device-specific facts from your own manual on page 1.

Why does it start with other devices?

Because if many devices stopped together, the cause is on the server, platform or carrier. You save a trip to the vehicle.

How long should I wait after a fix?

At least one report interval of the device. The interval is in the device configuration, and you note it on page 1.

Does it tell me what the LED colors mean?

No. LED meanings differ by model. Write what your device shows in normal operation on page 1.

When do I replace the device?

After step 10: swap in a known-good unit on the same vehicle. If the swap reports, the first unit is the problem. Send the log with the return request.

What is Tracom's role here?

Tracom makes the devices. This flowchart is a general tool. It does not replace the instructions for your model or your supplier's support.
