If anyone has the base TPM system that doesn't tell you which pressure is low, you can add the following PIDs to see the pressure on the app:
Mode/PIDs: 2120, 2121, 2122, 2123, 2124 (one is for spare tire)
Units: PSI
Equation: A
Header: 600
You'll have to let air out or put it in one tire at a time to see which tire is which PID
You wouldn't happen to know the Scangauge equivalent codes, would you? This would be useful.
I don't know for sure, but I attempted to translate torque to scangauge. Keep in mind this is after a day of drinking and smoking brisket so it might not work. Shouldn't REALLY break anything if I'm wrong. You'll need to change the 20 in the TXD and RXF to 21, 22... etc. for each tire.
TXD: 06002120 - 0abc xx yy, where abc is OBD header in torque, xx yy are the mode and PID
RXF: 02610320 - 02 zz 03 yy, where zz is xx+40 (might need to change the 02 and 03 to 01, 02 or 03, 04)
RXD: 1808 - AA LL where AA is the letter from equation in torque: A=18, B=20, C=28... and LL is 08 for single letter, not sure how to handle any torque PIDs that use more than one letter. (might need to try 0808, 1008, 2008 if 1808 doesn't work)
MTH: 000000000000 - MMMM DDDD ASAS - Multiply by, Divide by, Add/Sub by
