Failed TPMS reset and now Performance mode doesn't work?
I went through the drill to recalibrate the TPMS sensors per instruction on Cadillac FAQ to try and reset a funky LF wheel. In the process I was not able to get the RR to register. As a result I never received the double honk signaling completion. Now I'm not able to get the car to go into Performance Mode.
Has anyone else experienced this?
# 1) key in RUN, engine off
# 2) park brake set, cluster on pressure display
# 3) press and hold BOTH the LOCK and UNLOCK SIMULTANEOUSLY for about 10 secs until the horn honks. (on the Keyless Entry remote)
# 4) let air out of (or put air into) Left front tire until you hear another horn honk (only let the air our for about 3-5 seconds.... then be patient and wait for the honk... it could take up to 20-30 seconds before it honks)
# 5) repeat on Right Front tire
# 6) repeat on Right Rear tire
# 7) repeat on Left Rear tire
# 8) after left rear tire you should hear a double honk and the process is complete
# 9) verify the pressures on the cluster display
Ya, if all sensors aren't reading you can't enable performance modes....my sensors won't calibrate the 'normal' way either...I have to go to the dealer, you basically go through the same procedure but they have a device you hold next to the tpms in lieu of letting air out of the tires. Never been charged for it, they just do it in the service lane in about 5 minutes.

All 4 of my sensors just stopped reading one morning when I started my car after a cold snap...a cold snap here meaning 20's..haha. I can still go into competitive mode and turn off the stability control. I would like my sensors back though.
