Re: [opendiag] Re: changing R8 to 150K worked for me

Hi Jens,

The 140k resistor is there because the specification of
the interface says that the impedance should be around
150k when reading from the vehicle ecu. Using a higher
value should also work as long as the current through
the resistor is enough to drive the transistors.
