How to relearn tire monitors
I have a 07 Tahoe LT3. I just rotated the tires and I'm trying to relearn the tire sensors. It's not going to happen. I read the manual and it seems simple enough but I must be doing something wrong. Can anyone help? I really dont want to bring it back to the dealer.....

RE: How to relearn tire monitors
1st, make sure you have a way to reinflate close by (air compressor or short trip to gas station) When I did mine I had to let a lot of air out of each tire before the horn beeped. My pressures were real low when I was done.
Here's the procedure that worked for me. I know you said you checked manual but you must be missing something
[align=left]The TPMS sensors may also be matched to each[/align][align=left]tire/wheel position by increasing or decreasing[/align][align=left]the tire's air pressure. If increasing the tire's[/align][align=left]air pressure, do not exceed the maximum inflation[/align][align=left]pressure indicated on the tire's sidewall.[/align][align=left]You will have two minutes to match the first[/align][align=left]tire/wheel position, and five minutes overall to[/align][align=left]match all four tire/wheel positions. If it takes longer[/align][align=left]than two minutes, to match the first tire and[/align][align=left]wheel, or more than five minutes to match all four[/align][align=left]tire and wheel positions the matching process[/align][align=left]stops and you will need to start over.[/align][align=left]The TPMS sensor matching process is outlined[/align][align=left]below:[/align][align=left][/align][align=left]1. Set the parking brake.[/align][align=left][/align][align=left]2. Turn the ignition switch to RUN with the[/align][align=left] engine off.[/align][align=left][/align][align=left]3. Using the DIC, press the vehicle information[/align][align=left]button until the RELEARN TIRE POSITIONS[/align][align=left]message displays. If your vehicle does not[/align][align=left]have the DIC buttons, press the trip odometer[/align][align=left]reset stem located on the instrument panel[/align][align=left]cluster until the RELEARN TIRE POSITIONS[/align][align=left]message displays.[/align][align=left][/align][align=left]4. If your vehicle has the DIC buttons, press the[/align][align=left]set/reset button. The horn will sound twice to[/align][align=left]indicate the TPMS receiver is ready, and[/align][align=left]the TIRE LEARNING ACTIVE message will[/align][align=left]display. If your vehicle does not have the DIC[/align][align=left]buttons, press and hold the trip odometer[/align][align=left]reset stem until the horn chirps twice and the[/align][align=left]TIRE LEARNING ACTIVE message is[/align][align=left]displayed.[/align][align=left][/align][align=left]5. Start with the driver's side front tire.[/align][align=left][/align][align=left]6. Remove the valve cap from the valve cap[/align][align=left]stem. Activate the TPMS sensor by[/align][align=left]increasing or decreasing the tire's air pressure[/align][align=left]for five seconds, or until a horn chirp[/align][align=left]sounds. The horn chirp, which make take up[/align][align=left]to 30 seconds to sound, confirms that the[/align][align=left]sensor identification code has been matched[/align][align=left]to this tire and wheel position. To decrease[/align][align=left]air-pressure out of a tire you can use the[/align][align=left]pointed end of the valve cap, a pencil-style air[/align][align=left]pressure gage, or a key.[/align][align=left][/align][align=left]7. Proceed to the passenger's side front tire, and[/align][align=left]repeat the procedure in Step 6.[/align][align=left][/align][align=left]8. Proceed to the passenger's side rear tire, and[/align][align=left]repeat the procedure in Step 6[/align][align=left].[/align][align=left]9. Proceed to the driver's side rear tire, and[/align][align=left]repeat the procedure in Step 6[/align][align=left].[/align][align=left]10. After hearing the confirming horn chirp for the[/align][align=left]driver's side rear tire, the horn chirp will sound[/align][align=left]two more times to signal the tire learning[/align][align=left]mode is no longer active. Turn the ignition[/align][align=left]switch to LOCK.[/align][align=left][/align][align=left]11. Set all four tires to the recommended air[/align][align=left]pressure level as indicated on the Tire[/align][align=left]and Loading Information label.[/align][align=left][/align][align=left]12. Put the valve caps back on the valve stems[/align][align=left]The spare tire does not have a TPMS sensor.[/align][align=left]If you replace one of the road tires with the spare,[/align][align=left]the SERVICE TIRE MONITOR message will be[/align][align=left]displayed on the DIC screen.

I have tried everything repeatably add air release air at least 6 times with no luck. The most I can get is the first tire driver front. After that my time runs out and I have to start over. I guess it's back to the dealer (I hate that place).... Thanks for you're input.......

Have all of your caps off and be ready to go. Also use a key or something that allows you to let air out faster.Like I said you have to let a lot of air out. It's not so much how long but how fast you let it out. If you only drop a pound or two in 30 seconds it may not register.

RE: How to relearn tire monitors
I know I have done that. I increased the air pressure to 40lbs and then even removed the valve stem guts to release the air faster, thebest I could do is one wheel, driver front.....
