I hear the M shows the PSI on the Nav screen. not sure why they configured it differently on the G35.

The BCM just compares the actual pressures to the preset minimum, it doesn't care why the pressure is lower or how fast it dropped.

I checked the pressure in all of the tires, including the spare (don't actually think that one has a sensor), and it didn't go off.
Dealer did it in about 45 minute, using the new Consult III tool.

The cars been great since then except for losing my voicetags in my phonebook as others have complained about.

Sorry to post this in the 2007 section since I have a 2004, but my service manual reads the same way. (that the ECM must be calibrated even for tire rotations)
I've rotated my tires three times now and never had a problem. I looked at the service manual today and I believe you can remove the connector labeled M91 "tire pressure warning check connector" to keep the light from coming on. ('07 manual shows a similar item labeled as "switch" M23 connector.)
I have been studying this because I don't want to spend the money on sensors for summer wheels.
Any thoughts?
