How do I disable TPMS alerts on my JK?

[Speartip]

I have a related question. If one lets the air out of the tires to say 20 lbs. the TPMS light will come on the dash. Is that all that it will do. Will the Jeep go into limp mode or something like that ?? If all that happens is the TPMS light comes on, why worry about going through the trouble of resetting the limit through the OBD. ?

It won’t go into limp mode or anything like that . Guys Just don’t want to see that light .
On start up it does have a brief “alarm” when the low tire pressure light comes on .
I disabled my TPMS using Jscan cause one of my air pressure sensors in a tire is faulty . Don’t know which one . Getting new rims soon and going with traditional valves with no sensors . The system isn’t the most reliable .

I disabled mine because I normally run just at or below the alarm threshold. And every time the temps drop close to freezing or I air down for a ride on the beach or trail, I don't want to deal with it.

This is what I’m getting on my JScan:
What does this mean?

B210A
System Voltage Low
Basic Description:
System Voltage Low
Module Type:Tpms

Just go to Discount Tire and they will check your tire pressure sensors

Thanks, I’ll try that tomorrow.

I did go and check with some tire companies and they had no clue.
I went, then, to a mechanic and he thought the low voltage issue could be the main battery or the auxiliary battery?
Thoughts?
Getting to the Auxiliary battery is a chore/pain!

You have an auxiliary battery?

 

[Dwphillips]

I have not tried to get it out yet, but I think so, Supposedly under the fuse box. I’ve watch several videos on removing it by taking the fuse box apart.
That’s a little scar for me.
I’m just not sure which battery is making the scanner show low voltage.

I thought that was a JL thing, not JK... Am I missing something?

 

[Dwphillips]

No, I have a 2018 wrangler JK unlimited.

 

[Dirty Dog]

Interesting. I can only find info on the JL auxiliary battery.

 

[Danarch]

I believe some 2018 are JK and some JL’s due to how they rolled them out. So even though it’s a 2018 it could be a JL.

 

[Dwphillips]

From what I understand Jeep built JKs for half of 2018 and the rest of the year built JLs.
I’ve attached a photo of my engine bay.

Notice my fuse box is in front of the battery.
on videos I’ve seen of jls the fuse box is near the fire wall

 

[Dwphillips]

It is a JK!
Now is there any special technique to changing out the auxiliary battery?

 

[Dirty Dog]

That is indeed the engine bay of a JK. But I do not think the JK has an auxiliary battery. The JL and Gladiator do, but I can find no source that has any info on one for the JK. If you were told it is under the TIPM, then I would start by removing the battery to see if that would give me any access.

 

[Dwphillips]

I’m going to take your 1st advice and not worry about it until I see some objective findings. Thanks

I feel like a real dummy with my questions about an Auxiliary battery in my JK. Yes it is a 2018 JKU. But everywhere I look and all that I read, JKs, do not have an auxiliary battery!! Right???

 

[Acxman]

Did you ever consider that the mechanic just assumed you had an aux battery ?

 

[Dwphillips]

Yes, also I think when everyone hears 2018 they think it’s a JL.
It’s a Jk!!

That's kind of what I've been saying since you mentioned it... I initially thought you meant an aftermarket dual-battery kit.
