I love people figuring out CAN stuff. Let me know if you need anything to get your project further.
Looks like a lot of those ID's line up with some older Toyota CAN messages that are decently documented on the internets.

The above link seems to contain some similar ID's.

The above link might be a bit too new and doesn't contain similar ID's but might give you some more insight into Toyota's packet structure within the ID.
EDIT: Also, only 13 ID's? Very, very common on new vehicles.
