Anyway to easily reset TPMS on a 2018?

A carefully placed small piece of electrical tape solves my light problem when I run my 2nd set of wheels and tires with no TPMS sensors.
In the mid-eighties I was living in Heidelberg. There was a short time period that the $ to DM exchange rate went sky high so it was a great time to buy a car. We always wanted a Jaguar so I went to the local dealer to see what they had.

I was the first private person to buy a car at the dealership. He was a factory authorized tuner so he had a bunch of cool cars. One was a month old XJ-V12HE with a brand new engine. He had sold the car as a company car and just bought it back very cheaply, realized he couldn't sell it as a company car so was selling it on fire sale.

I ended up buying it and it turned out to be the most reliable Jag ever - the only problems I encountered were the typical Jag tank switch that went bad a frozen handbrake.

So, why am I saying this and why did the car have a new engine?

The prior owner had an oil pressure light come on that he resolved with a carefully placed small piece of electrical tape.

I actually ended up buying a XJS-V12 as well.
 
Pretty sure I came across both gen4 and gen5 methods on this forum.

On the 4th gen it's just disconnecting a cable, then jumpering 2 pins.

On the 5th gen it's just jumpering 2 wires on a connector, but you leave it connected.

TPMS is great for people who don't pay attention to their car's status or maintenance needs. To everyone else it's an annoyance, especially those of us who air down occasionally.

I asked because the threads I've followed have been inconclusive or simply cover with tape.

I grew up without it. TPMS is a pretty good system, not sure I agree with your blanket statement, no matter we all have opinions. Get debris/nail/screw in the freeway on a long drive, loose pressure, see it before you feel it *shrug* I dunno I think that there are other features far more nanny than that.

I air down all the time, as well as monitor the PSI, I like knowing where it is at, regardless if I am filling, driving aired up or down.

So true and this is where it can help every driver.

One of the most common tire issues is a slow leak. You pick up a nail and it (mostly) plugs the hole but will deflate in a couple of hours or over night. With modern tires, you can't tell by a visual inspection if a tire is low - you need to check it.

I'm not sure how she does it, but over the last couple of years she's picked up three nails. In each case (we check tire pressure monthly at the same time that we give our dog her heartworm and flea meds.) we found the leak in the AM as my wife was going to work and the TPMS alerted by the time she got to the bottom of the driveway.

In each case, the TPMS saved the tire. Had she driven on the tire longer then the tire would have been damaged beyond repair.
 
I think that was a 4th Gen.

Mine is stuck on 24/7 for now. If someone figures it out on a 5th I'm all ears.

I think this is the on you talking about.
Write-up: How to Disable (Bypass) the TPMS



Here you go.

Pretty sure it was forum user [MENTION=144375]dot_tom[/MENTION] that posted the TPMS light mod on a Facebook group.



Hey, that was me. I cannot take credit as I found the how to somewhere in the depths of this forum.

Just disable it all together. I’m now running rubber valve stems also.

Made this jumper wire

Jumped these two wires together. They are 5 & 6 on the tpms sensors module. (Light green and dark green. Right next to each other behind driver dash panel.)

Light is forever gone.

Yep, VAG did that until they went to the indirect method.

Audis went to indirect, but Porsche has kept individual pressure sensors.

Not sure what VW's use...

Agree with your maintenance comments. Mixed bag for sure.

Well seems they might of changed something on 2018.

I shorted 5 & 6 and light is still on. Light green and dark green.

Used a quick splice and no go


Edit

Nevermind use the right size quick splice if you going do this lol.

First try i used one too big didnt even cut the insulation

The wires being so small made it hard at first. Glad to hear you got it working!
 
I have done it twice at Discount tire. I went in for a nail and another time for a rotation. Mentioned my TPMS was acting weird and they programmed all 4 each time no charge
 
Disabling TPMS

Depends on the manufacturer.

My car monitors individual sensors per wheel, and will accept new OEM sensors into the system automatically. When I swap between summer and winter wheel sets, it just takes a few seconds for the car to ID the new sensors.

The 4th and 5th gen runners seem to make it more difficult that necessary. I opted to just disable TPMS completely in both of them. Super easy in the 4th gen, and only a little more involved in the 5th.

How di I disable the TPMS system of my 2017 4 runner SR5
 
What car do you have that senses the new TPMS transmitters? Acura/Honda does, but I didn't think that ant 4R/LC does that currently.

While it may be possible to disable the system, it is a violation and, quite simply, foolish. Prior to the implementation of the TREAD Act, the majority of cars on the road had under inflated tires and a significant amount had pressure that was at least 25% under the placarded value.

A violation of what? #LOL #OMG

The consumer isn’t violating anything by disabling the TPMS. But a tire dealer would be violating Motor Vehicle Safety Act (49 USC 30122(b) by making your TPMS inoperative by installing rubber stems on your truck’s wheels. But if your TPMS wasn’t working at the time you went in to get new tires, that’s OK. They didn’t make the system inoperative, it already didn’t work. It’s a confusing issue for everyone, consumers, dealers, tire dealers, repair shops.
