The T373B is a Plaspy compatible OBD II GPS tracker engineered for plug-and-play vehicle monitoring. Designed around a Telit xE910 cellular modem and a u-blox MAX-7 GNSS module, the T373B delivers reliable real-time tracking, telemetry and driver behaviour data over GSM/WCDMA networks while offering Bluetooth 4.0 LE for local device extension and configuration.
The compact T373B connects directly to the vehicle OBD II port to provide fleet management, anti-theft and fuel monitoring capabilities without complex installation. With built-in diagnostics (OBDII, SAE J1939, J1708/J1587), DTC alerts, an immobilizer digital output and support for firmware over-the-air updates, this Plaspy compatible tracker is ready for deployments that require accurate positioning, rapid time-to-first-fix and rich vehicle telemetry.

How It Works with Plaspy
When integrated with Plaspy, the T373B streams vehicle location, on-board diagnostics and event-driven alerts so fleet managers and operators receive actionable telemetry and real-time tracking. Plaspy leverages the tracker’s GPS/GLONASS positions, trip profiles, DTC status and immobilizer control to deliver a full-stack fleet management experience—visibility, safety and remote control from a single dashboard.
- Real-time location and telemetry updates (GPS/GLONASS position, speed, course) for continuous vehicle tracking.
- On-board diagnostics and DTC reporting (RPM, ECT, fuel level, fuel consumption) to support fuel monitoring and maintenance alerts.
- Ignition and engine cut (immobilizer) digital output for anti-theft actions and remote vehicle immobilization.
- Driver behaviour events (harsh braking, acceleration, cornering, etc.) transmitted to Plaspy for driver scoring and coaching.
- Bluetooth 4.0 LE connections for mobile-based configuration, sensor pairing and local feature extensions.
