ZenTRACK OBD – Operations Guide
(For operations, support teams, and fleet admins)
Written By Support Team

1. Purpose & Scope
This guide explains how ZenTRACK OBD behaves in day-to-day operation and what operations / fleet admins should expect once devices are deployed.
2. What ZenTRACK OBD Does
Once installed and configured, ZenTRACK OBD:
Collects GNSS data:
Location, speed, heading
Reads OBD-II parameters:
Ignition status, vehicle voltage, and other telematics metrics (based on config file)
Communicates via cellular network to:
ZenduOne
Other backend systems integrated for your deployment
Optionally communicates with BLE sensors and beacons if enabled in configuration.
The configuration file (12v vs 24v, region) determines:
Thresholds for ignition detection (voltage-based)
Event profiles (e.g., harsh braking/acceleration tuned for light vs heavy duty)
Reporting intervals and behavior.
3. Daily Operations Flow
Vehicle Use
Driver operates the vehicle normally.
ZenTRACK OBD powers up from the OBD port when ignition is turned on.
Data Transmission
Device sends location and telemetry based on:
Ignition state
Movement
Settings in the configuration file (e.g., periodic or event-based reporting).
Platform Visibility
In ZenduOne or your platform, you should see:
Vehicle on the map
Recent events (ignition on/off, trips)
OBD-based metrics (where configured).
Remote Management
Firmware updates and config changes can be managed via:
Teltonika FOTA (for firmware/config)
Platform-specific interfaces (if integrated with FOTA APIs or proprietary tools).
4. Operational Best Practices
Keep a mapping of:
Vehicle ID ↔ Device IMEI ↔ SIM ICCID.
Use appropriate configs:
12V profile for light-duty fleets
24V profile for heavy-duty fleets
Use FOTA groups to:
Roll out firmware/config updates in a controlled way.
Monitor:
Devices that have not reported for some time.
Devices with frequent disconnects or poor GNSS, and investigate (see Troubleshooting).
