Xhorse VVDI Key Tool Plus does not have the diagram of SCL pin 1 SDA pin 11. I would like to share below. (Key Tool Max is used, which is also applicable to Key Tool Plus)
Follow the Key Tool Max built-in diagram to connect the Key PCB.
Put the transponder 46 chip into the coil of Key Tool Max, and then read it.
The HD connection diagram for SCL and SDA.
Hope it helps!
