Since pure EVs like the Nissan LEAF do not produce emissions (exhaust), the OBD II requirements
for exhaust-producers do not apply. The EV manufacturers generally include an OBD connector,
but they usually take liberties with usage of the pins there. Most use pins 4 and 5 for some sort
of ground, and pin 16 as "12 volt" battery power. If pin 8 is used, it is usually Switched "12v".
However, even these conventions should be carefully checked before attaching anything to
an EV vehicle's OBD connector, if any.
The 2011 LEAF had 3 CAN buses on the OBD connector, each a "standard" 11/500 CAN bus.
We called these the EV, AV, and CAR CAN buses, since the EV bus had mostly info associated
with running the Electric Motor and Battery Pack. The AV bus mostly handled communication
between the parts of the Audio/Visual displays and the associated controls. The CAR bus
had messages to control the functions that any "normal" car would have, like lights, turn signals,
