Makes sense now. Probably just a cookie cutter design across a few vehicles.Sensors 7 & 12 are reserved for the rear bumper for stellantis vehicles that have parallel and perpendicular parking assist.

I REALLLLY want to know about this. I have a guess at this point:Parksense options...
I wonder what a JLU Rubicon would show as.............I REALLLLY want to know about this. I have a guess at this point:
I think Sahara means everything but Rubicon ( plastic bumper ) and Rubicon means steel bumper. I bet "Mopar" means MOPAR lift installed. Those things would affect the parking sensor tuning.
Then again the Mojave and Rubicon are both higher than other trims stock. Perplexed. I might try some tests with cones behind the truck and at angles and toggle the setting.
If anyone has a scan from a Freedom Edition with rear parking sensors please post it! Those have steel rear bumpers.
I wouldn’t put too much thought into those settings at all. They are the same settings used on other Dodge, jeep, ram vehicles. All the logs I have of various ram trucks, they vary between Sahara, rubicon, summit, etc, with no rhyme or reason.I REALLLLY want to know about this. I have a guess at this point:

For JSCAN I got my changed from 38 to 35. JSCAN has preloaded 5 psi increments, you can't go between. They've set up the choices in "fives".Someone has to have figured out a way to change the TPMS pressure?I tried resetting both the "Heavy Load" and "Pressure threshold" settings. It changed what it says on the dash to "infate to", but the amber TPMS light and red tire preessure still were illuminated. Must be another setting I'm missing?
OK, so if this is like the RAM trucks I need the PIN. Funny the Tazer can reset it without the PIN, but the lowest it will go is 25psi and I need 20psiFor JSCAN I got my changed from 38 to 35. JSCAN has preloaded 5 psi increments, you can't go between. They've set up the choices in "fives".
• Light Load Inflation Pressure Front / Rear Tire: Leave at 0.
• Max Load Inflation Pressure Front / Rear Tire: for vehicles that have a load sensor (Gladiator, RAM
trucks). This value is used as the minimum pressure when the vehicle is fully loaded.
The above max load inflation number on mine was 38 before I changed it which is the door jamb sticker number.
After I changed it if the pressure is low it now says "inflate to 35 psi"
TPMS is no longer in a TPMS module - there's a box there, but the sensing from the sensors has been moved. They moved it mid-2021 model year. (RFH?)
I reset mine with JSCAN, no pin. I just changed the number from the factory 38 to the closest to the 36 I wanted and that was 35. I then closed out of JSCAN, shut down and the next day, it was at 35 when the tire pressure was low due to sub-0 temperatures. I purposely didn't yet inflate the tires for winter as I wanted to see how it would react.OK, so if this is like the RAM trucks I need the PIN.

I find it odd that AlfaOBD mentions a pin to make the change because if a code is needed, JSCAN should also require it.I don't have JSCAN. I have Alfa OBD and Tazer......neither of which have worked to get my pressure down to 20psi yet
Just for the heck of it, I tried to reset the radio hub and Alfa asked for a 5 digit PIN.PIN and RF Hub reset is only needed on FCA RF Hubs through 2018.
It is not required on these newer RF Hubs (except for fob programming).
I used the "Max Load Inflation" Front and Rear. Which settings are you changing?Someone has to have figured out a way to change the TPMS pressure?I tried resetting both the "Heavy Load" and "Pressure threshold" settings.

I first tried "Max load inflation pressure" and "Update pressure thresholds" as those were the ones listed set at 25psi in the "Vehicle configuration file". I then also did the "Light Load inflation pressure" to make sure. All netted the same results. The dash said "Inflate low tire to 20psi", but when I did so, the errors did not go out.I used the "Max Load Inflation" Front and Rear. Which settings are you changing?
Hmmm... I only changed Max load inflation and left the others at the defaults. I'll have to go deflate and see if the lights come on, but the last time I was on the trail I don't remember them being active.I first tried "Max load inflation pressure" and "Update pressure thresholds" as those were the ones listed set at 25psi in the "Vehicle configuration file". I then also did the "Light Load inflation pressure" to make sure. All netted the same results. The dash said "Inflate low tire to 20psi", but when I did so, the errors did not go out.
I then reset the light load back to 0 and the other two back to 25 psi and lights were out.
I also performed reboots without any change. I sent a message to Tazer asking if they could reduce the thresholds in a future firmware update.
