TPMS light playing games. - Toyota Yaris Forums

If you want to find out what the issue is/was, you can get the TPWS to flash the light in a pattern which indicates what the trouble code is. Check out this post for instructions:

If you have a scan tool will the codes show up there? Thanks!

I believe there are separate electronic control units for the engine & transmission, the ABS system, the airbags, and now for the TPMS. They're accessed separately. The code reader only gets the info from the engine control unit.

No (unless it supports Toyota specific enhanced diagnostics). Standard scantools, like the ScanGauge, only support some portion of the standard 229 engine / emissions PIDs.
