Question about 2006 Hummer H3
44PSI?? is that what your car recommends...
1. check and make sure that your tires are inflated to the correct pressure
2. turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns off and then release the switch.
3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

A) Check tire pressure on all 5 tires to make sure all is well in pressure land.
b) Set parking brake
c) Turn on Key, then quickly turn headlamps on and off 4 times
d) 2 horn beeps sound to signal you are now entering the 5 minute calibration mode. The User Manual is wrong since the TPM ICON does NOT FLASH as documented.
e) Go to left front tire and inflate or deflate for least 10 seconds
f) Wait for beep to signal ready to move on
g) Go to right front tire and inflate or deflate for at least 10 seconds
h) Wait for beep to signal ready to move on
i) Go to right rear tire and inflate or deflate for at least 10 seconds
j) Wait for beep to signal ready to move on
k) Go to left rear tire and inflate or deflate for at least 10 seconds
l) Wait for beep to signal ready to move on
M) Turn the key to loff to lock position - most people would conclude the reset should be done at this point.
When you now turn your key back on, the damn DIC is still whining after all your hard work. The trick is you have to actually drive the vehicle before the TPM reset is finalized. The programmer needs to be drawn and quartered on this fine mistake. The manual should at least note this requirement.
You don't have to touch the spare other that make sure pressure is up before you start. If you take more than 5 minutes, you have to start over with the ignition off.
Good luck and keep me posted if you have more questions.
