The Danlaw TCU collects CAN data (OBD) from multiple ECUs — including EMS and ABS systems — generates real-time alerts (harsh acceleration, harsh braking, cornering, and more), and captures GPS position data. All this is processed onboard and transmitted to your backend via MQTT with end-to-end encrypted communication. It also supports full vehicle diagnostics — VIN readout, LIDs/PIDs, DPIDs, DBCs, DTCs, Freeze Frame data and Actuator control — accessible via Bluetooth Dongle or MQTT.

All data between device, mobile app and cloud backend uses end-to-end encryption — no raw vehicle data exposed in transit.
Reads all vehicle parameters, DTC error codes, freeze frame data and actuator states from any CAN-connected ECU.
GPS and IRNSS (NavIC) dual-constellation positioning with periodic cloud reporting and configurable update intervals.
Real-time alert generation for harsh acceleration (HA), harsh braking (HB), cornering (CA) and other critical driver events.
Full vehicle diagnostic capability — VIN, LIDs/PIDs, DPIDs, DTCs, Freeze Frame and Actuators — via BT Dongle or MQTT.
Remote firmware flashing of connected ECUs over CAN UDS Over-the-Air — no workshop visit required for software updates.
Ignition-based trip start/end detection, configurable sleep modes and automatic key-off wakeup for low-power fleet deployments.
During network outages, the 4G TCU stores over 40,000 data packets locally and syncs automatically when connectivity resumes.
Full J1939 SPN parameter support for trucks, buses and commercial vehicles — reading torque, axle load, engine hours and more.
