The T373A is a plug-and-play OBD-II GPS tracker designed for vehicle tracking and fleet management and is fully Plaspy compatible. Installed in seconds on any standard OBD-II port, the T373A brings real-time tracking, in-vehicle telemetry and driver behavior reporting to fleets, rental operators, insurers and roadside assistance providers without complex wiring or installation. Its support for multi-band GSM/WCDMA networks, combined with a u‑blox GNSS receiver and rich OBD-II data, makes the T373A a practical choice for scalable, data-driven fleet operations.
Built for reliable anti-theft and operational visibility, the T373A reads full OBD-II data (including SAE J1939 CANBUS and common protocols) and reports RPM, speed, engine coolant temperature, fuel level and fuel consumption. An onboard immobilizer (engine-cut) output, Bluetooth 2.0 for peripherals, FOTA firmware updates and robust motion sensing make the device a compact, high-value GPS tracker for Plaspy-powered solutions.
Key Highlights
- Plaspy compatible plug-and-play OBD-II GPS tracker for quick deployment and centralised fleet management.
- Real-time tracking and detailed telemetry: reads RPM, speed, coolant temp, fuel level and fuel consumption via OBD-II/CAN.
- Onboard immobilizer (engine-cut) digital output for anti-theft response and remote vehicle disablement when integrated with Plaspy controls.
- Integrated GPS/GLONASS (u‑blox MAX‑7) with internal high-gain antenna and AssistNow A‑GPS for fast TTFF even when hidden.
- Bluetooth 2.0 enables pairing with compatible sensors or accessories to extend telemetry and condition monitoring.
- Driver behavior and safety analytics using a 3-axis accelerometer (harsh braking/acceleration, cornering and more) plus geo-fencing options.
- FOTA firmware updates and auto APN/time zone detection streamline large-scale fleet rollouts and maintenance.
How It Works with Plaspy
When connected to Plaspy, the T373A streams location and vehicle telemetry to the Plaspy platform where data is normalized, visualized and actioned. Plaspy ingests OBD-II parameters, diagnostic trouble codes, accelerometer events and GPS positions to deliver live maps, alerts and reports tailored for fleet management, anti-theft workflows and insurance telematics. Integration is straightforward: the T373A communicates over cellular networks and supports remote firmware management so device behavior can be adjusted centrally from Plaspy.
- Real-time location and telemetry updates (GPS/GLONASS coordinates, speed, heading).
- OBD-II live data and Diagnostic Trouble Codes (DTC) for maintenance and fault detection.
- Fuel monitoring and fuel consumption reporting captured directly from the vehicle network.
- Remote immobilizer / engine-cut control via the digital output when enabled by Plaspy policies.
- Bluetooth sensor support for expanded telemetry (temperature, BLE beacons) and accessory pairing.
- Driver behaviour events and geofence breach alerts (circle, rectangle, polygon).
