I don\'t know about OBD-II commands. Tesla provides an interface that allows you to connect wirelessly to your car and control various aspects as well as pull data from the car\'s instrumentation stream.

*Most* of the OBD2 interface is for collecting data FROM the vehicle.
Mode 8 commands can be used to control certain subsystems -- but,
that\'s pretty much \"vendor specific\". I.e., you\'ll have to get
the data from \"Honda\" (which likely will not come \"free\")

Remember, OBD2 is an interface to the ECU -- not the \"vehicle\" itself.
Specifically, you can\'t /directly/ access the CAN bus(es) -- there
can be more than one -- from the OBD2 interface. I.e., IF you can access
a particular CAN bus module via OBD2, the ECU is acting as an \"agent\";
translating your OBD2 request into the appropriate CAN-bus command(s).

If you\'re intent on pursuing this, I\'d start by monitoring the CAN bus
/feeding a door lock mechanism/ while manually issuing a door unlock
request (pushing whatever button in the vehicle is responsible for
unlocking the doors). You may be able to capture the CAN bus sequence
that does this.

As above, this won\'t likely give you any information about what you\'d
need to do at the OBD2 interface!

*But*, you could add your own module to the bus and convince your module
to issue the appropriate command(s). Or, interface to that \"unlock
button\" that you manually triggered, above.
