Diagnostic Tool

An advanced PC application and hardware interface for ECU diagnostics, ECU flashing and live data monitoring via USB. Supports CAN and K-Line protocols across the full diagnostic workflow — from fault reading to parameter adjustment to firmware programming.

Overview

Professional ECU Diagnostics & Flashing

The Danlaw Diagnostic Tool is an advanced PC application used for ECU diagnostics and ECU flashing through a USB hardware interface. The tool supports live data monitoring from any connected ECU, and allows engineers to reliably adjust parameters during active task implementation. Built for workshop technicians, OEM validation engineers and software development teams who need a dependable, accurate window into ECU behaviour.

What's Inside Both Variants

Encrypted Communication

All data between device, mobile app and cloud backend uses end-to-end encryption — no raw vehicle data exposed in transit.

Full CAN / OBD Data Capture

Reads all vehicle parameters, DTC error codes, freeze frame data and actuator states from any CAN-connected ECU.

Real-Time GPS Tracking

GPS and IRNSS (NavIC) dual-constellation positioning with periodic cloud reporting and configurable update intervals.

Driver Behaviour Alerts

Real-time alert generation for harsh acceleration (HA), harsh braking (HB), cornering (CA) and other critical driver events.

Remote Diagnostics Interface

Full vehicle diagnostic capability — VIN, LIDs/PIDs, DPIDs, DTCs, Freeze Frame and Actuators — via BT Dongle or MQTT.

OTA ECU Flashing (4G)

Remote firmware flashing of connected ECUs over CAN UDS Over-the-Air — no workshop visit required for software updates.

Smart Trip Management

Ignition-based trip start/end detection, configurable sleep modes and automatic key-off wakeup for low-power fleet deployments.

40,000+ Packet Offline Buffer

During network outages, the 4G TCU stores over 40,000 data packets locally and syncs automatically when connectivity resumes.

Commercial Vehicle J1939

Full J1939 SPN parameter support for trucks, buses and commercial vehicles — reading torque, axle load, engine hours and more.
