I've tried two diagnostic tools in my Sirion's ODBII socket. Neither has found a working protocol. The socket's light has remained red. All fuses test OK. All accessories disconnected, car restarted several times.
I found reference to my vehicle at http://www.outilsobdfacil...-compatible-obd2/daihatsu
.. but I don't know how to enter the numbers. However, the most important thing is to find out if anybody else has ever managed to connect one! (Anybody?)
