hi i need to know where the tachometer drive signal comes from
i think there is problem with my ecu but dont know exactly.
I have 0 volts at pin 5 of the ecu where it should be apox 7.2 Volts
i have added some useful info from the workshop manual. Maybe someone could help me to trace back the problem and where the signal source comes from.
With a bluetooth consult device i can read RPM but the RPM gauge doesnt work anymore. Plus HICAS ABS TCS and SLIP lights and the mentioned parts all in fail safe function i think it is all related but cant proof it.
