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:
Jeep Gladiator JScan TPMS Thresholds - TPMS module not responding? IMG_2306

Going back to the Dashboard and running the advanced scan doesn't report any trouble codes:
Jeep Gladiator JScan TPMS Thresholds - TPMS module not responding? IMG_2304

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:
Jeep Gladiator JScan TPMS Thresholds - TPMS module not responding? IMG_2305

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

Yup - the warnings are mostly 'industry standard' at about 25% below the "expected psi".
My stock tires were 38 psi - it came on about 29 psi with those tires.
When I set it down for the new tires, it now comes on about 27.

So what you say about when it comes on, and goes off, that's normal.

I never used the reset all ECUs part. I just waited a while.
How long has it been since you retried?
Did you disconnect everything and start over in case it's a communication issue?
