Is the 12VDC signal on the OBDII connector always on or is it switched with the ignition key?
If not always on, then is it determined by manufacturrer or make and model?
Thanks for your help...
There seems to be no rhyme or reason to it. Very often the DLC shares the fuse with the cigarette lighter. So if your cigarette lighter has power when the ignition is off, most likely the DLC does, too.
