[rflight]

Hi Folks I just removed my 91 CAI Tune in preparation for my upcoming timing chain recall, I have noticed that the TIPM lights and TIPM Fault Message (SYSTEM FAULT ) are now gone from my evic message area. There was nothing changed with the tires on the car so I am puzzled with this . I guess when the recall is complete and I reinstall the 91 CAI Tune via Intune I will know if the TIPM lights/message comes back again or not, thanks for any input.

If I understand correctly, changing tunes also clears the NGC's RAM which is where DTC's are stored. If something is still wrong with the TPMS then the light will come back on once the threshold is met.
