Cloud-Based Vehicle Diagnostics

 

OnlineDIAG is a professional cloud-based platform for on-board vehicle diagnostics. Built for modern workshops, it delivers a fast, flexible, and intuitive web interface that streamlines reading diagnostic trouble codes (DTCs), viewing real-time sensor data, and performing advanced ECU functions—all from your browser. To get started, simply connect any SAE J2534 Pass-Thru compatible interface.

 

 Instant Reports: Generate complete vehicle diagnostic scan reports with DTC descriptions data in seconds.

 

Remote Access: Read live vehicle parameters from any internet-connected device—PC, tablet, or smartphone.

 

 Dealer-Level Functions: Access ECU coding, adaptation, and service resets typically reserved for OEM tools.

 

 Secure & Encrypted: All diagnostic sessions use end-to-end encryption with full audit logging for compliance.

Technical Requirements

 

OnlineDIAG is a software-only platform designed to work with any J2534-compliant Pass-Thru device. The diagnostic capabilities available to you depend on your interface hardware. For full functionality, your Pass-Thru device should support the following protocols as defined in SAE J2534-2:

 

 CAN Bus: Pin selection on 6&14, 3&11, 3&8, 12&13, 1&9, 7&11 with baud rates 50, 125, 500, and 1000 kBit/s.

 Fault-Tolerant CAN: Pin selection on 1&9 with baud rates 50 and 125 kBit/s.

Single Wire CAN: Pin 1 at 33.333 kBit/s baud rate.

 K-Line Protocols: ISO9141 and ISO14230 (Keyword 2000) with pin selection on 1, 3, 6, 7, 8, 9, 11, 12, 13, 15 and baud rates 1200, 4800, 9600, 10400, and 115200 bit/s.

UART Echo Byte Protocol for legacy vehicle systems.
