I've used JScan before to clear trouble codes but not to make any adaptations.
I figured before I needed to use it to change the tire size and axle ratio, I should try and lower the TPMS thresholds for what the new tires will be aired up to. I changed the "Max Load Inflation Pressure Front Tire", hit Go, and then did the same for the rear. Did the !Restart all ecus: Tire Pressure Monitor - Power On Restart and hit Go. Did the Run - Off - Run cycle as suggested, walked away for 10 minutes.
The adaptations for lower warning pressure show up in the adaptations menu. I verified that at least the front is actually at the new value by airing the the left front tire way down and then back up. Warning in the dash didn't come on until a value ~25% below the new setting and turned off well below the OE 37 psi.
Issue is that when I go to the Modules page for the Tire Pressure Monitor, this is what JScan comes back with:
Going back to the Dashboard and running the advanced scan doesn't report any trouble codes:
And as the scan is running I can see where it at least says it is checking the Tire Pressure Monitor.
It can read other modules:
I did not verify before making the adaptations that the TPMS module could be read.
If this module should be readable, are there some other steps that I need to do to get it working?
Thanks,
Philip
