Well I did it! Discovered that the arbitration ID for TPMS is 333
I then noticed that the messages go in a pattern like this:
(1476987407.909367) can0 333#0000000000000F
(1476987408.009644) can0 333#0000000000001E
(1476987408.109524) can0 333#0000000000002D
(1476987408.208971) can0 333#0000000000003C
I wrote a script to keep playing those messages via canplayer and the light seems to be staying off!
PS I still want to figure out how to play 15 minutes of a candump file!
