so at factory setting, when your tire pressure drops below 32psi you get the Low tire pressure On Light on the MFD. can I change this so it goes off at lets say 28 psi?
If so, it looks like Adaptation Channels 5, 6, 7, and 8 in the TPMS module at address 65 have values that correspond to the "specified" tire pressures in tenths of a bar.
However, I'm puzzled why you'd want to run less than 32 psi.
