FAQ
When is it time to replace the controller instead of fixing it?
Replace the controller if it has multiple failed I/O ports, isn't receiving firmware updates anymore, or if diagnosing the fault costs more in downtime than purchasing a new, more reliable device would. For modern fleets...

Can bad ignition data cause compliance violations?
Absolutely. Without accurate engine-on/off times, you cannot prove compliance with idle regulations or properly reconcile hours of service. This creates real risks during safety or emissions audits.

How do I test if the problem is with the wiring or the controller itself?
Use a multimeter to check for 12V on the ignition sense wire when the key is on. If voltage is present but the status isn't reporting, the controller's input circuit is likely faulty. If there's no voltage, you need to t...

Why would a vehicle controller stop sending ignition data?
It's usually a physical problem such as a loose or damaged ignition sense wire, a blown fuse, corrosion at the connection, or a firmware fault that resets the controller's input settings. It's almost never related to cel...

How long should a GPS tracker take to come back online after a reset?
A healthy device on a strong network should report within 2-5 minutes. Delays beyond 10-15 minutes typically indicate a network or device failure, not normal operation.

Can repeated hard resets damage a GPS tracker?
Yes, excessively cycling power can corrupt the GPS module's memory and degrade the cellular modem's ability to register on the network, which leads to longer delays each time.

When should I stop troubleshooting and replace the tracker?
Replace it if delays persist after you've verified correct APN settings, done a SIM swap, and tried a firmware update. The decision lock is when the cost of lost tracking data exceeds the hardware cost.

Why do some trackers work after reset but others in the same fleet don't?
This often points to a batch-specific SIM card provisioning issue or a firmware mismatch, where a subset of devices can't authenticate on the updated carrier network.

How many immobilizer failures indicate a systemic problem rather than isolated incidents?
More than one sporadic failure in a 90-day period across a fleet batch often points to a firmware or hardware lot issue. This pattern demands a batch review and potentially a redesign of the security protocol itself.

What is the hidden risk when an engine immobilizer fails but GPS tracking continues to work?
The hidden risk is that you can still see the vehicle moving on your tracking map, but you've lost all control to stop it. This creates a false sense of security where your team operates under the belief the vehicle is i...

What are common failure patterns with engine immobilizers?
Common failures often occur in the handshake between the telematics gateway and the vehicle's CAN bus, sometimes due to firmware mismatches or voltage sags. The most costly assumption is thinking a 'command sent' status...

What compliance risks arise from immobilizer malfunctions?
The biggest compliance risk is an inaccurate audit trail. If your system logs an immobilize command as successful but the vehicle continues moving, it creates discrepancies that can violate insurance or regulatory requir...
