Low tire pressure set-point bypass

[Bobo57]

Not sure I want to go to a Tazer yet. But is that OBD JScan for real? Will I be able change tire pressure notification set-point?

I read that scanner won't let you return to stock.

You heard wrong. You absolutely can undo any changes you make.

You are misinterpreting this. This merely means that the changes won't undo themselves. Do you really want all your settings to revert to stock simply because your battery dies? You can absolutely 100% undo the changes if you choose.

That may be the case but that's not how the paragraph reads.

When running at lower tire pressures, is there are way to bypass the low tire pressure set-point so that you no longer receive those annoying notifications?

So my tire pressures drifted below 30 psi, which I understand is the threshold for the tire pressure warning signal. After I inflated them to 34 psi the warning is still on. Anybody know how to shut this off? I don't want to have to add some app to do that.....................

Nope, fill to 37 or use tazer or jscan to set the threshold yourself. You're going to have to give in somewhere . Either ignore the warning, or use one of the devices mentioned here to get more control over your rig. The silver lining here is the tazer and/or jscan device do allow other changes if you wish: bigger tires, gears, QOL (quality of life), etc.

I set mine to 15 PSI via the Tazer Mini. Also changed my max to 35 PSI.

Interesting as I've never had that problem before. Guessing it might be due to the tire rotation and I will try the OBD scan tool.

I too had a period of time where I never got a warning when my PSI was around 32-35. I think it was because one tire was 2 PSI within the 37lbs range.

Inflated above 37 then down to my standard inflation pressure of 32 and all good now. But I think I will try the OBD reset route when I get a chance.

15 PSI????? When did this change? Tazer minimum limit on the 23 model year was only 25 PSI.

That’s what I remember 25 was the lowest I could go. 23 here as well

I used the Taser Mini on other Jeeps that I have owned, but I was not contemplating using it on my 392 due to fingerprinting and potential warranty issues. It is a pain in the ass to take on and off for dealer visits (although I do most of my maintenance at home). I see someone mentioned extension cables that may make that easier, but a sign to the dealer that there has been something installed. Is anyone else concerned about the Taser or JL Scan impacting any warranty claims at the dealership?

Not in the least. Look into the Magnusson-Moss Act.

I agree that the Magnusson-Moss Act protects the owners from this, but there is the concern that a dealer writes it up a non-warranty and records it as such in the system. Although it may eventually be covered, it could involve additional steps and legal fees to prove your point, and paying for covered repairs until further action is taken. This was always a concern, but more so now with Stellantis' poor financial performance and perhaps an agenda to cut costs. I just wondered what the concensus of the forum is about this.

A concern? The act isn't new. Any documented cases of this actually happening?
The onus is on the dealer to prove that the modification was the proximate cause of the failure. My own experience is that they're not going to invest the money to do so. It's easier and cheaper to simply repair the vehicle. I had a supercharged '95 Trans Am that had the rear end replaced twice. All my vehicles are modified pretty heavily. I have never had an issue with a warranty repair. Not once.

As with anything, do your research to the point where you're comfortable with whatever decision you make. As many have stated here, as well as ZAutomotive, you can unplug the device prior to dealer visits and there's nothing to worry about. I wouldn't stress too much about a hypothetical scenario. Enjoy your rig and whatever means you use to modify
