From this old thread: RE: Mounting a wheel back on the H3?

I posted this, and it all applies to the 2007.
[align=left]"From the H3 06 Owners Manual: [/align][align=left][/align][align=left]TPMS Sensor Identification Codes[/align][font=arial][color=#231f20][size=1][align=left]Each TPMS sensor has a unique identification code. Any time you rotate your vehicle’s tires or replace one or[/align][align=left]more of the TPM sensors, the identification codes will need to be matched to the new tire/wheel position.[/align][align=left]The sensors are matched to the tire/wheel positions in the following order:[/align][align=left]left front (LF), right front (RF), right rear (RR) and left rear (LR).[/align][align=left]You will have one minute to match the first tire/wheel position, and five minutes overall to match all four[/align][align=left]tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than [/align][align=left]five minutes to match all four tire and wheel positions the matching process stops and you will need to start over.[/align][align=left][/align][font=arial][color=#231f20][size=1][align=left]The TPM sensor matching procedure is outlined below:[/align][align=left]1. Set the parking brake.[/align][align=left]2. Turn the ignition switch to ON with the engine off.[/align][align=left]3. Turn the exterior lamp switch from AUTO to ON four times within three seconds. A double horn[/align][align=left]chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and[/align][align=left]flashing TPMS warning light indicates the TPM matching process has started. The TPMS warning[/align][align=left]light should continue flashing throughout the matching procedure. The SERV TPM message will[/align][align=left]be displayed on the Driver Information Center (DIC).[/align][align=left]4. Start with the left (driver’s side) front tire.[/align][align=left]5. Remove the valve cap from the valve cap stem. Activate the TPMS sensor by increasing or[/align][align=left]decreasing the tire’s air pressure for 10 seconds, then stop and listen for a single horn chirp.[/align][align=left]The single horn chirp should sound within 15 seconds, confirming that the sensor identification[/align][align=left]code has been matched to this tire and wheel position. If you do not hear the confirming single[/align][align=left]horn chirp, you will need to start over with step number one. To let air-pressure out of a tire you can[/align][align=left]use the pointy end of the valve cap, a pencil-style air pressure gage or a key.[/align][align=left]6. Proceed to the right (passenger’s side) front tire, and repeat the procedure in Step 5.[/align][align=left]7. Proceed to the right (passenger’s side) rear tire, and repeat the procedure in Step 5.[/align][align=left]8. Proceed to the left (driver’s side) rear tire, and repeat the procedure in Step 5.[/align][align=left][size=2]9. After hearing the confirming

 

That's what I though, until the warning message didn't go away. I'm hoping once I drive it this morning it will.

Thanks again Doc. We'll see what happens [&:]

 

Well, the error message went away after the truck started moving, so apparently doing it isn't enough. It has to actually move for it to go away. Very odd.
