Re: [opendiag] K Line Problem

hey,
suppose that the car have no particular problem at
ignition or grounds, best and easy way to filter the
noise is to use first and obligatory at input a
treshold fast comparator (example LM139). Then you can
also conect serial with the bus a RF shock inductance
and a small capacitor (not bigger than 1nF)... this
filter the radio frequecy / GSM or other noises
