Hi. I just got a bluetooth OBD2 transmitter to connect to my multimedia player. It turns out that the OBD2 port is live all the time and it ran my battery down. Is OK to make the always hot lead to switched power?

My obdeleven was in my port 2 weeks without the car being touched. Still glowed and started, albeit slower. Was 28f and snowing when I had to move it. My ignition has to be on for it to read the computer. What I've dongle you have? Even my cheap one can be set to power saving mode when key is off. But you could change it to switched power. Have you checked your battery?

Me Bad. The battery was shot internal discharge. The OBD2 times out- turns off after 1 hour of no use.
