The Jaltest JDC107.9B is the USB connection cable between the Jaltest Link V9 and your PC or laptop, in USB-C configuration. It is a black cable measuring 177 cm with a USB-B connector in a black housing with rectangular collar on the interface side, and a slim black USB-C connector with metal trim on the PC side; just before that connector sits a black CE flag label around the cable. This USB-C connector is the difference from the sister version JDC107.9, which terminates in USB-A on the PC side: if your laptop has USB-C ports only, this cable is the right choice.
This connection establishes the data link between the interface and the diagnostic software, allowing you to run a diagnostic session with a fixed cable rather than wirelessly. Which control units you can subsequently access depends on the vehicle and the modules in your licence; for the vehicle itself you will also need a separate vehicle diagnostic cable. Because the cable belongs to the interface rather than a vehicle manufacturer, it is compatible with every active Jaltest module (CV, AGV, OHW, MHE, Marine and GSE).
KEY BENEFITS
IMPORTANT NOTES
Applications and functionality
This cable establishes the connection between the Jaltest Link V9 and the PC. What you can subsequently read out is determined by the vehicle and your licence.
Control units you can access
- All control units permitted by the connected vehicle and your licence: This cable determines the PC connection only; it does not define which systems are covered.
What you can do
- Read and clear fault codes: Access and clear the fault memory of connected control units following repair.
- View live data: Monitor current sensor and system values in real time.
- Control components: Activate actuators to verify their operation.
- Parameters, calibrations and maintenance resets: Where Jaltest provides these for the relevant system.
- Important: Which of these functions you see is determined by the vehicle and the modules in your licence — not by this cable.
Compatible vehicles and applications
The interface determines compatibility, not the vehicle model. This cable is part of the Jaltest Link V9 and not tied to a specific vehicle manufacturer.
- Jaltest Link V9 — the interface generation this cable is designed for
- All segments: Commercial vehicles, trailers, buses, agriculture, construction, forklifts, marine and GSE
