LOL Ok ... oh that's too funny. Just a practice i became accustomed to, now i know.

I am sure the DIC is incorrect now. It read 34 on three and 35 on one after I set them to 38 using my Longacre.

Read the other responses about the "relearn" so really no point in following up other than to say the DIC and my Longacre are not reading the same. I guess it's more useful for detecting a possible issue... not for pinpointing your tire pressure.

You are absolutely, 100%, correct.

A tire guage trumps a tire sensor any day.

I've checked with different gauges and got accurate reading while the car said something different. I'd give the car a 3 or 4 psi acuracy. Or NON-acuracy actually.

Typically it's there to tell you if you are losing air in a tire. You get in and the tire light is on, or one reads 25 while the rest read between 33 to 40, then you know something is wrong.


And to re-state what has been said.

Your sensors read pressure like a tire gauge. You can't reset your tire gauge to read different pressure. It reads pressure one way. It's not like a scale you can 'zero' out. Think of it as a simple pressure gauge on each wheel that transmits the tire pressure to the car. You can't change the sensor. The sensor does not interface with the car. Tha car just grabs a signal that a sensor sends out and which position it transmits to. It's a one way signal.

I aired up all the tires today at work with a good gauge. After diving a little ways the tire pressures on the display changed to pretty close to what I had put in.

One other thing that the manual post didn't mention is the fact that the turn indicator light (the blinker) for the tire that is currently supposed to be "learned" will illuminate. In other words, instead of trying to remember where to start (driver's front or passenger's front), look for which blinker is light up, and you'll know for sure which tire sensor is currently being learned. I thought that was a pretty good way of doing it.

How could you possibly know that. I was panicing in a hurry to get to all the wheels to deflate every time I did it.

Good to know though.

To be honest, I'm not sure where I found it out...I may have read it in the actual manual? I'm going to have to run out and grab it. I know I read it somewhere though...I just remember when I first did it last fall with the tire/wheel combo I got for winter. I was afraid the new sensors wouldn't work, but it worked like a champ, and the procedure was pretty straight forward. Let me go get that manual...

EDIT - well, it's not in the paper manual, at least not in the learn section. I know I'm not crazy, I know I found out somewhere. If it wasn't raining out, I would try it now to make sure I'm not giving false information But I'm damn sure that I even checked that the blinkers really do come on (they don't blink though) when I was putting the summer tires back on a few weeks ago, because I couldn't remember if it went from PassFront to DriveRear, or PassFront to PassRear - the car just "showed" me which one to do next. This independent control of each blinker was the reason I figured the car could warn the driver ("Michael, I suspect a malfunction") that a particular blinker didn't work...
