HI, I HAVE AN 07 TAHOE LTZ. I'VE ROTATED THE TIRES, FOLLOWED THE INSTRUCTIONS JUST AS STATED IN THE OWNERS MANUAL SO THAT THE COMPUTER CAN "RELEARN" THE POSITION OF THE TIRE PRESSURE SENSORS. I CAN GET THE TRUCK INTO THE "LEARN" MODE (HORN BEEPS TWICE, PARKING LAMP LIGHTS) AND I HAVE TRIED INCREASING AND DECREASING THE PRESSURES OVER MANY DIFFERENT TIME FRAMES (SECONDS) AND PRESSURES. I NEVER GET THE FIRST HORN HONK TO INDICATE IT HAS LEARNED THE LF TIRE, AND THUS I CAN'T FOLLOW BY GOING TO THE RF, RR, LR TIRES. I'VE READ ALL I CAN ON THE NET AND SHORT OF GOING TO THE DEALER, DON'T KNOW WHAT ELSE TO TRY. THANKS, MIKE

Dealer had to reprogram mine. I got the learn mode two honks the first honk at the left front tire, and that was it. I am unclear on if there is a horn honk at each wheel or not. My conclusion now is no. Instead you must follow the parking lights that are on.

I had to let quite a bit of air out of the first tire before it signaled me to go to next tire, after that everything went as it should have.

Same here. I had to have a tire replaced, a week or so ago. While they were at it, I had the guys at Discount Tire rotate the tires, too, since the new ones had already been on there for about 5k miles. Well, I didn't realize until this morning that they never did the re-learn. So, the fronts were reading as rears and the rears were reading as fronts. It seemed to take for-ever for the driver's front to finally 'register' with the system on the truck. After that, all went smoothly.

 

I've done three rotations now. There is a honk at every wheel.

Agreed. When it senses the change in pressure for "that" tire/wheel, it'll beep and you can move on to the next one.

Well at least I know now I wasn't doing it wrong. It seems that it must not register quickly or have good reception or something to that affect that causes it not to recognize or respond to the sensors very quickly.

The first tire I did this morning... It took long enough that I was getting concerned that I was letting TOO MUCH air out of it. It took several seconds.

Mike, Welcome to the forum. You should get a honk after each wheel and then 2 honks at the end. Then you will have a TPM error on your DIC. Then you take it to the dealer. :dunno:

Well, I finally gave up and had to take it to the dealership. Just hope I don't have to do that after every rotation. Thanks to those that wrote in with information. I'll try it again in a few months and see what happens.

Yea what he said. Just to throw in my two cents there is SUPPOSED to be horn chirp verification at each wheel but any tech who has done a hundred of position learns will tell you that 10 of them did not verify, watch the marker lights, the corner that needs to be programmed next should be lit and once programmed should go out. Also just letting out air doesn't seem to work for alot of them, try removing the core till you get the verification, you will loose a considerable amount of air doing that so make sure a compressor is near by.

I did my 08 Silverado last week and it went really smoothly. I got the first honk after loosing 5 psi. The next 3 were done about the same. Horn chirps after each tire. We did my friends 07 this weekend and couldn't get it to go past the first tire. He had the valve removed and the tire was almost flat. The warning light lit on the dash, so it saw the tire was low. We tried removing air, adding air and doing the first for 10 seconds and moving on, nothing seemed to work. One difference, he could access the Learn Tire mode using the DIC switches, mine doesn't have that, I had to use the Lock/Unlock on the key fob. I wonder if there is a computer upgrade that would make it work?

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.
