Question

Hello! I am trying to get CANbus data from a Toyota Hilux 2021 but I can´t get any data from any twisted pair of cables, so I want to use a bluetooth obdii dongle (elm327) but I cant get it to work with the FMB640, I did manage to send canbus data on another vehicle with the FMB920 device. What could be wrong here?

Hello.

FMB640 device is dedicated for trucks and uses CAN standard supported in heavy vehicles (FMS, SAE J1939 CAN interface).

To read CAN data from your vehicle with FMB640 you schould use CAN adapter.
