LAGA, C6 Corvettes require the magic wand. Maybe your truck has the same system.

Using the GM TPS "wand" is easy, but who has one in their garage, right? The setup procedure the owner can do does work, but you can have issues if you are parked near another vehicle with TPS or perhaps a similiar radio frequency. When TPS was first introduced in my plant we had to relocate the learn station due to Radio Freq. issues from an overhead conveyor. Try to do the learn procedure in a different location.
GMboy, that makes sense. My driveway is in the line of sight with a grocery store across the street. My radar detector is constantly going off in the driveway. If I try the relearn in another location without rotating tires, will I screw up the system and have to take it back to the dealer again?

No you won't hurt the system. It will just relearn the same thing again. And if it doesn't complete the relearn, it will just revert to the current state.

LAGA - check this TSB out, it may be your problem:
Subject: Rubber Valve Stem Pressure Release Learn Method - keywords check chirp horn low monitor program relearn tire tpm #PIT4220 - (12/28/2006)
Models: 2007 Cadillac Escalade, ESV, EXT
2007 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2007 GMC Sierra, Yukon, Yukon XL, Yukon Denali, Yukon Denali XL
--------------------------------------------------------------------------------
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may comment that they are unable to get the TPM system to learn the new style rubber valve stems using the pressure release method. This may be inconsistent from one tire sensor to the next and one vehicle to the next. If the J-46079 tool is used the learn procedure can be done.
The release of air through the valve stem sets up a resonant vibration frequency that can trick the TPM Sensor into thinking it is in motion. This causes the sensor to transmit multiple pressure update messages, not Sensor ID learn messages. The Remote Control Door Lock Receiver (RCDLR) does not recognize the pressure update messages when it is in a Learn Mode. This will not allow the vehicle to acknowledge the sensor with a horn chirp, and the learn procedure cannot be completed.
Recommendation/Instructions:
For rubber valve stem sensors only, if you have any problems performing a learn procedure using the pressure release method, use the J-46079 tool to perform TPM Learn procedures.
For customers who are unable to perform the learn procedure at home, perform the learn procedure using the J-46079 tool and advise that engineering is working on a fix and parts to correct this condition will be available in the future.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

Thanks. It sounds like this is the case. When I first talked to the counter person about my troubles, he asked if I was having any problems with my remote entry. They were aware of the connection between the TPMS and the RCDLR and that some people who had trouble with the relearn also had trouble with their remote entry. They did not mention the TSB.
Gotcha on the roads. 40 years and nothing changes there! One problem with the US law is that it only requires notification to driver when pressure drops 25%. What you need is THE system that is ultra sensitive and gives immediate notification of a 1% drop or even less if you want to save a wheel. The valve type in the VAG vehicles is a Beru unit, I think. I don't know that it is ultra sensitive and only the dealers have the equipment to change the set point, I think. You also need to be able to change the set point precisely. The Smartire is widely used on commercial vehicles. However, if the bands break easily, it isn't going to help you. You might want to check with a Porsche or BMW dealer to see how versatile their valve stem units are.
Can't use the OEM stems are the chipsets are different and won't talk to my receiver.
The Smartire does a tone of things, temperture, etc.
But the beauty is that I set it to alert me when the pressure drops below 29 PSI. You can set it to alert when the pressure goes too high & too low on a specified parameter for each individual tire and can handle up to 6 or 8 tires per display - as it is geared toward rvs and such as well.
And it gives real time pressure as well, which is a +++ as on the BMW platform, and even their current latest generation vehicles, it only displays an alert if the pressure drops and that's it.
I love the unit.....just not too fond of the *bulk* of the valve transmitters as I find it detracts away from a beautiful custom wheel. Strap Sensors - I guess it has it's pros and cons in my book as well ;-)
Sure wish ALL vehicles had sensors built into the abs module like my old M3. Still that car only displayed when the pressure was low as well - not as full featured as the Smartire product.
