Sweet! Keep us posted with any updated results.

To borrow a little saying from Thomas Edison...
I found 3 more ways NOT to disable the TPMS.
I'm still on that quest.
The wiring diagrams are spread all over the place for that system.

Como

Well hell, My dealer told me it did. Sorry for the miss info. I never checked. Just took there word for it. I got 37s now so dont care anyways but they told me that they were having probs. with that system because of the spair. My bad.

No matter how many times I follow the directions on how to get light load working I can't!

Anybody have this trouble or know a trick to the system so I can actually air it down below 60 in the rear? Anything below that and I get the TPMS light, and the light load indicator just blinks and blink and blinks and blinks... The the TPMS light nightmare again!!!

Oh Bullshi*! Cram the star scan down the techs throat, pull it out his a$$ and go do it your self. Thats what I had to do. Im so POod with Lyeing techs and service managers I feel like this
!!!!!!!jail Time!!!!!!!

Your rear pressure options are 60 & 45. Nothing in between. Go to my 1st post, follow the TSB to the letter! It will work. You have to reset the TPMS with the high pressures THEN turn off the truck, lower the rear to 45 lbs. Then as soon as you turn on the keys, set the LL button before starting. These things are dam smart. Hard to fool.

If they dont activate til they are rolling can you take them out and put them in the truck?? If they were in the truck they wouldnt roll ever.

A little something I found:
I'll put it in the OP as well.

OPERATION

CAUTION: The TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use aftermarket tire sealants or balance beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.

CAUTION: After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the Tire Pressure Monitoring Sensor.

CAUTION: Tire pressure sensor valve stem caps and cores are specially designed for the sensors. Due to risk of corrosion, do not use a standard valve stem cap or core in a tire pressure sensor in place of the original equipment style sensor cap and core.

CAUTION: Any time a sensor is to be reinstalled in a wheel, a new seal, nut, cap and valve core must be installed on the stem to ensure air tight sealing.

NOTE: TPM thresholds have been established for the original tire size equipped on the vehicle. Use original size tires only to maintain system accuracy.

The battery operated tire pressure sensor is both a transmitter and a receiver. The TPM sensor can be forced to transmit if using a special tool such as a TPM-RKE Analyzer, or from a transponder. The TPM-RKE Analyzer has the ability to change the sensor mode and to diagnose a faulty TPM sensor. Using a TPM-RKE Analyzer can take up to a minute to force a transmission from a sensor.

The High Pressure TPM sensor can be in one of the following modes:



Sleep Mode - A new TPM sensor will be in this mode. If placed on the vehicle as a road tire, the TPM sensor will transmit once every 20 seconds when the vehicle is driven at speeds over 15 mph (24 km/h). If the vehicle is not moving, the sensor will only transmit on a pressure change greater then 2 psi (13.8 kPA). Driving the vehicle continuously at speeds over 15 mph (24 km/h) for more then 4 minutes will change the sensor state into 30 BLOCK MODE. The TPM sensor will not return to SLEEP MODE. Now, if the vehicle has been stopped for 20 minutes, the TPM sensor state will change to PARK MODE.
Park Mode - This is the correct mode when the vehicle is not moving. The sensor will transmit once every 13 hours to update the WCM, or will transmit on a 2 psi (13.8 kPA) delta change. The sensors will internally take a measurement of the tire pressure every minute to determine a change in tire pressure.
30 Block Mode - If the vehicle has not been moving for more then 20 minutes, or if the sensor's mode was forced to Park Mode using a TPM-RKE Analyzer, the sensor's operating mode will transition from PARK MODE to 30 BLOCK MODE once the vehicle is driven over 15 mph. In this mode, the sensor will transmit once every 15 seconds when the vehicle is driven at speeds over 15 mph (24 km/h) for the first 30 transmissions. After 8 minutes of continuous driving above 15 mph (24 km/h), the TPM sensor will change to DRIVE MODE.
Drive Mode - In this mode, the sensor will transmit once every minute when the vehicle is driven at speeds over 15 mph (24 km/h). At any time that the vehicle speed drops below 15mph, the sensor will not transmit. The sensor mode will still be in drive mode when the sensor reaches speeds over 15 mph (24 km/h). If the vehicle has been stationary for more then 20 minutes, the TPM sensor will change to PARK MODE.
Each sensor's (transmitter) broadcast is uniquely coded so that the wireless control module (WCM) can monitor the state of each of the sensors on the four rotating road wheels. The WCM can automatically learn and store the sensor's ID while driving "within 10 minutes continuously above 15 m.p.h. (24 Km/h)" after a sensor has been replaced. The vehicle must be stationary for more then 20 minutes in order to initiate the learning sequence.

The sensor IDs can also be programmed using the TPM-RKE Analyzer Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the correct location. (LEFT FRONT, LEFT REAR, RIGHT FRONT, and RIGHT REAR) Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then follow the programming steps outlined in the diagnostic Scan Tool for "Program Tire Pressure Sensor ID w/ TPM Tool" under "MISC" for the "WCM/WIRELESS CONTROL MODULE".

As I read this it occurs to me that if I want to put a lift and 35" tires on my new 09 that I have to accept a TPMS light aluminated on my dash the whole time? Do I assume this correctly or is there a fix for this situation???

It is my understanding the dealer has the technical ability to change the pressure setting. However, they are limited my Federal Law. It will take finding a tech that will "work" with you. If he likes the brand of beer you bring, might help too.

ok, just a little info from my part time job at Discount Tire. The TPMS is required on all vehicles by 2008. All vehicles that DO NOT have dual rear wheels have the damn little sensors. The dealer has the ability to change the light load value with the star scan, most just dont know how to do it, and are just to lazy to do it. The newer trucks ie 2009 and 2010, the dealer should have the abillity to change max load. This is usefull for those that run the bigger tires with load range E2 and D2 (same load rating just different air pressure). The sensors have a 20% value assigned to them, Meaning that at 20% above or below the rated value, the light goes on. Every manufaurer rates a different value % so be forwarned on that. The motion of the tire is what will keep the battery in the sensor charged. Dealer says no, but i have seen a sensor sit for 3 days go dead and then work after being in a tire. And we do have tools to take them out of the diffrent modes, so i know they were just not in park mode or something like that. What will confuse you is if you drive next to someone and they have a low tire, your light can come on. Kinda stupid IMHO.
