Found a cool way to enter diag mode on the RB1 radio but not sure what to do with it. There is a tire calibration mode that I am interested in but not sure what it calibrates...any ideas?

Oh, to enter diag mode see below:

To display the RB1 Factory Diagnostic Service Menu:
- Press Tone
- Select Fade
- Press Tone twice
- Select Bass
- Press Tone twice
- Select Treble
- Press Tone four times
