Hi Everyone

Does anyone know if the the 2009 Civic ODB2 port "live" when the car is off?

I need to install a solar trickle charger and the ODB2 port needs to be live or else I'll have to wire it directly to the battery (pain the the button wires hanging outside the car )

Thanks!

It's supplied a constant (fused) power source (term# 16) and ground (term# 4 and 5) at all times.

AFAIK this is a rule and all OBDII compliant vehicles must be wired this way on these specific terminals. (don't quote me on this though)

Thanks, I don't have to wire it. The Solar trickle charger comes with a nice ODB2 port so I just need to plug it in and charge away.

I couldn't find anything in the manual telling me if if the ODB2 port is always on.
