FBH USB Diagnostic Cable to enable the FBH to be connected to a PC laptop for diagnosis using the Webasto WTT software.
For Discovery 3 & 4*, Range Rover Sport Vehicles.
- A PC Laptop running Windows 7 or newer (MAC devices are not supported).
- The ability to install software , drivers, and configure ports.
WTT Software download link below.
The USB Driver is usually automatically installed by Windows and not generally required. However a download link is below if needed.
* Please note, This diagnostic cable will communicate with the FBH on the Discovery 4 and the later (post facelift) Range Rover Sport vehicles to read and clear faults and view live data from various FBH sensors, but you may be unable to physically run the heater. This appears to be an issue related to the WTT software not the diagnostic cable.
This is not an issue with the Discovery 3 or older Range Rover Sport models.
