Is it problem traction inverter?

Hi Nuna,

for diagnostics you need different cables for the Rx and FMx trucks. FMx uses dongle + cable and Rx uses canbox and two cables. The canbox is located within the diagnostic case and the dongle is a seperate unit - it connects to the laptop USB port.

Sorry, you have to spend some money....

Hope this info is of some help
