That doesn't come into play until you mount it and start rolling. The rolling motion is what activates the transducers.

When the light load switch is functioning properly, will it stay illuminated or will the light go out? Does the TPMS light have to be on for the switch to function? Just trying to figure this out. I've had my tires set at "max load" pressures for quite some time because I couldn't get this switch figured out. I'm trying to see if I'm doing something incorrectly or if the switch is bad somehow.

I finally got my light load switch (LLS) to work. It stays illuminated continuously and no TPMS warning light.
My TPMS light was on when I bought the truck (about a month ago). The dealer aired it up to 60 front and 45 back. He said the the light should go off as soon as the truck learned the correct pressure??? I tried airing up the back tires to 60 and the TPMS light still stayed on. I finally said if the TPMS light is going to stay on, I was going to lower the pressure in the back so the truck didn't ride so rough. When I lowered the pressure back to 45, turned on the key but didn't start the truck and pushed in the LLS, the TPMS dash light went off, the LLS light stays lighted and all is well.

Also did the same thing with my cousin's truck.

Hey Brett, I have to say the spare DOES NOT come with a sensor valve in the spare !! Or at least mine did not. I checked mine out and there is none !!! I called the dealer and he said they don`t come in the spare tire. Maybe I am wrong anybody else have the same ???????

Well, I didn't follow dad2bike's instructions to the t, which was where my problem was. I misunderstood the process of this switch. I talked to the dealer and the tires have to be at the light load pressures, or a few pounds within those numbers. I was under the impression that the pressures didn't have to be at the "light load" value, and I was trying to use it at a value in between max and light (65 all around). Then I set my front's set at 65, and dropped the rears to 45 and the light load switch worked. It didn't work at first, but the truck must have known that I was headed to the dealer to get the newest flash because the morning on the way to the dealer the swith decided to work and has worked since. Wierd, but at least it's working now. Thanks to all for your replies.

Has anyone tried running nitrogen in their tires? I have heard they isn't such great differents in psi between the temperature differences. It might help out if its true.

No. I understand it is on all 2008 up to the 2500. 3500's don't have it.

good to know in case I end up in a new 08 or 09 in the buyback.

I ran it in my 06, and yes there was very little fluctuation due to temperature. My tires were always about perfect.

I didn't liek the nirogen because....

I had them put 45 in ther ear tires and 60 in the front. When I wanted to tow something, I had to air them up a bit, if I did so, then I had nirto and air in my tires and it cancelled out the benefits of having the nitro. So if your gonna do Nitro, try to pick a Psi that you won't want to or have to change frequently. I should have had them fo 60 in the rear, and I later did, but that extra 15 psi sure made it ride rougher.

That being said, I plan on doing it to my 08, and just doing 60 all around, once my new tires are mounted.

Nope. I'm rolling around on a spare right now on the back right corner because I had a blowout Saturday morning, and my TPMS light is on and there is no sensor at all in the spare wheel.

I did a bit of research into the wiring diagrams. I was able to defeat my TPMS at this time. I will post up how after I get some miles on it to be sure there are no related issues.
