I'll give this a shot.

Well, I figured out what the "problem" was! Apparently the 2011+ models come with an "Extended Storage Switch" in that fuse box by the dead pedal. It comes from the factory in the 'off' position. Apparently the dealer is supposed to switch it to 'on' before they sell the car.

I pushed in the switch until it clicked, and sure enough, the OBDII scanner turned right on!

More info on the "Extended Storage Switch" can be found in this thread:

Here's an image of the switch (snagged it from the thread I linked above):

Obd Readers.... my days we used to lick the dipstick and smelled the gas coming out while listening for random clunks.

Some OBDIIs incompatible with 370z?
 

I was looking at OBDII Scanners and the Panlong device claims not be to compatible with Nissans. Anyone know of any other devices that won't work? Are most of them equivalent or are there some favorites with additional features?

Thanks for any feedback.

All OBDII devices are electrically compatible and are able to read the basic PIDs. The Panlong unit may not have Nissan-specific info in its database.
