Can Forscan deactivate the TPMS system?

[CrabGuy]

Title pretty much covers it. My 2011 E350 (8800 GVW) constantly has issues with the TPMS. Part of the issue is the recommended rear pressure is 80psi and the front 60psi. If I drop the rear pressure back to 60psi for ride quality it alarms. Ford always resets it at oil changes with the courtesy tire rotation but they always set the rears back to 80psi and it rides like a metal wheeled skateboard unless I drop the pressure. They refuse to reduce the rear pressure due to liability. I'm sure the batteries are at their end of life and I don't want to go through the expense of replacing all 4 of them.

Thanks

We get this complaint a lot on 2500+ Ram trucks for the same reason.

For those you are pretty much stuck with the light.

I just ordered the cable last night for my 2020 Ranger and in the course of researching Forscan I saw where that is one of the things you can do.
On my old Sport Trac I replaced the sensors once because the batteries went dead, couple years later they did it again and I just put a piece of black tape over the light.

If you own a US vehicle/live in the states, no, one cannot, TPMS is mandatory in the states, unlike here in Canada where it is not. Up here it can be deactivated.

Lots of garages don't give a damn about stupid useless shit, and will pass you for a sticker.


Christ.. I've had a few garages give me stickers on vehicles with illegal exhausts... "if you get pulled over, you put this on after I gave you the sticker, right?" Right!

You're missing the point
Forscan will not deactivate the TPMS when attempted to on a US vehicle, but it will on a Canadian vehicle.

Aaah I see. Hadn't had any coffee yet lol. The software just literally won't allow for it to be deactivated.

I hate those lights and the concept TPMS. "Safety device" my a$$. It's our government "protecting" us my making us pay to idiot proof vehicles so drivers who refuse to check their tires can continue to be oblivious. Those sensors and modules cost way more than a decent tire gauge and actually do less. I usually find the tire pressure on my Escape 1-3 lbs low every month in the winter and the light never came on until one of my aftermarket sensors failed. Our parts guy was trying to save me some money for my snow tire wheels, I should have known better and bought the Ford ones.
My grandmother was Canadian and my grandfather was born in a bedroom located in Canada, but his front door was in the US so he was an American. That's close enough to disable TPMS isn't it?

Thanks. In the US vehicles over 10,000lb GVW don't have to have a TPMS. I've seen a few links to putting a good TPM into a sealed PVC canister with a Shrader valve and pressurizing it to the recommended psi/ I'm not sure if it would work with Ford's setup though. I have the little 2008 reset tool but am told it's useless on a 2011 model.

I wonder if you could change the parameters for it. On my old jeep I had TPMS set to go off at 1psi to avoid having the lights going off while aired down, so TPMS was still there, just not alerting me except for my custom range

I'm fairly certain Forscan can change the set pressure for the TPMS. I don't know if it will actually deactivate it (I doubt it can though), but you should be able to up the pressure that it throws the CEL at. I'm almost positive I've done it before, but it wasn't on a Ranger.

My SCTx4 tuner for my F150 can supposedly do this, I tried setting it HIGHER, but it never actually worked at all, I would check my tires and they would have 22 PSI in them, and I had set them to alert at 30. I put that setting back to stock and now I get alerted at 25psi like normal.

Yep. Thank the people who never even look at their tires, Ford’s poor selection of a tire for the Explorer and making a bad psi recommendation for said tire, and the politician’s desire to “do something” to sate the general population.

Many of the safety devices and warning labels we have are because someone was stupid enough to do it. Since we aren’t allowed to let Natural Selection solve the problem, here we are and they are allowed to live long enough to reproduce, thus further dumbing down the general population.

I don't think the TPMS can be disabled, but I am pretty sure that in NJ, it can pass inspection with the light illuminated on the dash.

^ in total agreement with you on this, I do not advocate or approve of any vehicle electronic or mechanical device that transfers the responsibility of what the driver should be doing & puts it on the vehicle to *safeguard* the vehicle moving down the road. If the driver is not competent then that individual should not have a driver's licence.
