Ok... need some technical input here.

I have winter tires with TPMS sensors that don't function properly.. so rather than spend $300 to have them replaced I need to figure out how to temporarily disable VSA for situations where my car is stuck in deep snow.

Since the TPMS light causes a fault situation where VSA is stuck "ON" I would like to try pulling a fuse that I can easily replace after I've unstuck the car.

I've pulled the fuse diagrams for the driver side, passenger side and under hood and it appears there are 3 fuses related to TPMS/VSA that I can pull.

1. Interior Fuse Box (Driver Side)

7.5A with the label ABS/VSA
7.5A with the label TPMS


2. Under-Hood Fuse Box

40A with the label ABS/VSA
30A with the label ABS/VSA motor



If I were to get stuck I would probably go for the driver side box since it would be easier to get to while staying inside the car. I'm just curious what you think or know the other fuses are for?

I'm also curious what would happen to my VSA if I pulled the TPMS fuse, I just need the TPMS light to reset in order to be able to use the VSA disable button on my dash.

Thoughts?

Thanks, however Honda TPMS and Toyota TPMS work differently. Honda TPMS need to rotate in a wheel to transmit so the canister doesn't work.

How many times have you been stuck in the snow where this would be needed? I got stuck, once in 1980, in our rear wheel drive 1978 Mercury Marquis and I was 12 years old. We pushed it out, no problem.

Last year once.. and it was very inconvenient.. I live in Canada where it snows 20-25 cms often.

Meh, cms of snow, big deal, we get inches of snow down here in Cleveland.:lmao:
My Accord is pretty good in the snow, better than my 04 Maxima that did not have traction control nor VSA which never got stuck either, but not as good as the MDX with SHAWD which was a beast in the snow.

This seems unlikely. If it's true, then there has to be logic built into the TPMS system that makes it not read/warn if the car isn't moving fast enough to generate the signal.

Also, if this were the case, then if you had a tire go flat overnight, the light would not be on when you got in the car in the AM, and this seems very unlikely. I will test this out later on by letting air out and watching the warming light while parked in the driveway.

Yes, there is logic built into the sensor to only transmit when spinning faster than 40km/h. Otherwise it goes into sleep mode. Service manual talks all about it. The TPMS low pressure light would only illuminate if you are driving on a flat tire faster than 40km/h... or come to a stop and have been driving slower than that speed no more than 5 mins.

Did the VSA fuse trick work? If so, which ones needed pulling out? We only want VSA de-activated when stuck in snow, which is a very rare occurrence.

I have the same problems with the possibility of my WIFE getting stuck in snow here in Canada.

Found this for the Civic, seems disabling the TPMS fuse will do the trick? Also looks like Canadian and US vehicles operate differently with the fuse removal trick. :)

You can disable your tire pressure light by pulling the fuse, but by doing that, the TPMS light will come on instead of your tire light. I've done numerous tests, by adding and dropping air. Pulling the Tire pressure sensor fuse you will still be able to deactivate the VSA. In other hands, if you decide to pull the VSA fuse, you will lose your electric power steering, and that isn't very fun to drive, its impossible to steer. lol


So I guess it can be done but it might be easier to just get help push our car out when stuck or not drive at all during inclement winter weather.

I had aftermarket wheels without TPMS on my 08 coupe last winter so I could not turn off VSA. Got stuck in a snow drift and needed to disable VSA to get out. I pulled the 2-2 and 2-3 fuses from the under-hood fuse box. These fuses are part of a multi-fuse. You have to remove the screws and pull the whole thing. Do not lose the screws! They complete a circuit. If even one of the screws is missing when you reinstall the fuse the fuse will not work. You also need to be aware that pulling this multi fuse will also disable your ABS and the passenger side fuse box which controls your amp if you have the premium sound system. Therefore I would not recommend permanently removing this fuse. I found that this was the only way to completely disable VSA. I got out of the snow drift in less than ten minutes then reinstalled the fuse.

^ Thanks for the very useful information Geoff. Much appreciated.

Much easier that having to keep two sets of TPMS sensors. I'm going to keep a copy of your directions in the glove box. :)

It snow like... and our town had a surplus of salt that could have been used many of times. Never have I needed VSA disabled. In fact it saved me arse at least once in slushy in between 3+ inch lane snow mounds going at speed.

Once I had one issue pulling up a slushy snow covered driveway, it was not plowed and my front was a wee low to the curb. Could not get any traction, even jerking the wheel left and right to snake up the blasted incline. I may have been able to power my way up if I had not slowed down to turn up the hilly driveway.

For those that got stuck, I'm presuming you already have good winter tires on?
Stock tires... never use winter tires or chains... both in mountains and krappy poorly maintained town roads. The right amount of power and driving skills will keep you out of trouble. Peeps don't realized going too slow is just as bad as going too fast.

In my case I slowed down to make my turn in, as if I were to on any given day. I did not realize I was driving into a slush box of sorts. But I never got stuck just could not move forward enough to get out of it.
