Key Diagnostic & Repair Features

1. DoIP & Next-Gen Protocol Integration

Modern vehicles require massive bandwidth to transport diagnostic data. With built-in DoIP, CAN FD, and J2534 support:

• Flash ECUs and run full-system scans up to 20x faster than traditional CAN networks.

• Access gateway-protected modules on late-model BMW (F & G Chassis), Mercedes-Benz, Land Rover/Jaguar, Volvo, and VAG group vehicles without external adapters.

2. AI-Powered Repair Intelligence & Diagnostic Guided Assistance

Troubleshoot complex electrical faults faster with integrated diagnostic repair intelligence:

• Component Location Maps: Pinpoint sensors, control units, ground points, and fuse locations instantly on-screen.

• Intelligent DTC Fault Analysis: The AI engine cross-references fault codes with real-world repair databases, giving you likely root causes, step-by-step diagnostic workflows, and component testing parameters.

• Interactive Wiring Diagrams: Access clean, colour-coded wiring diagrams with active circuit highlighting to trace power, ground, and communication signal paths directly to the fault.

• Step-by-Step Repair Instructions: Complete OEM reset procedures, torque specifications, and repair guides right at the vehicle side.

3. Online Advanced Coding & Programming

Perform dealership-level ECU reflashing, module matching, and personalised coding directly over a stable Wi-Fi connection.

• Online ECU Flashing & Programming: Supports key brands such as BMW, Mercedes-Benz, Audi, VW, Porsche, Land Rover, Jaguar, Hyundai, Kia, Nissan, Subaru, and more.

• Variant & Offline Coding: Recalibrate replaced modules, program blank control units, change vehicle parameters, and adapt retrofit options.

• Component Protection Removal & Matching: Streamline part replacements (steering locks, immobilisers, ABS units, instrument clusters).
