Aftermarket Wheels & Service Tire Pressure Monitor - SVC TPM

[f5fstop]

No fuse for jus this circuit. The sensors contain a battery, that directly signals the BCM. The BCM communicates the TPM message to the I/P cluster to turn on the light via the class 2 serial data link and the BCM chimes.
So, no fuse.
Someone last year had a great idea, that was for the BCM to recognize via the class 2 serial data link from the PCM/TCCM that you are in 4-Lo Lock and if you were in 4-Lo Lock, turn off the TPM warning, since this would mean you were not traveling on the highway. (I cannot remember who suggested it, but it was a great idea after I thought about it for a while.)
I actually passed this idea through GM engineering and GM legal, and the reply was very quick...NO. It is a federally mandated system that requires these TPM sensors on the vehicle, and no one will take responsibility of saying under certain conditions it will shut off the warning.
Car manufacturers are just a bit touchy on the subject of lawsuits lately.

Just got back from the HUMMER dealership to confirm the location of the TPM sensor. Turns out the sensor is located in the VALVESTEM.......and when I asked how much I was shocked to hear $200...........PER TIRE! Those are some damn expensive valve stems in this rig!!!

Luckily I still have the stockers so i think I might as well just swap them over......oh boy......8 unmounts\remounts\rebalances

Isn't that what you were already told three times in this thread.

I agree, but some don't want to believe....

Thanks f5stop - that picture clears it up. I was confused when you mentioned that it was mounted to the rim.....
