Flat Tire Error
I was in a underground parking garage, went to pay my parking ticket when then error left from tire flat and limited to 55 MPH came up in DIC ...
Opened drivers door and turned wheel left to look at it, It was fine, 2 min later it went away and never returned ...
Any ideas?
Thanks

Do you have run flats? Any idea how old your TPMS sensors are ? Could be you just have a sensor starting to go bad, or your tire is low, run flats can look ok but they may not be, you should also check the tire pressure instead of just a visual inspection.

What does the pressure now say? If correct, go onto tpms. They do use batteries and batteries are less powerful when cold. Overnight, it gets colder - that's why my smoke alarms start beeping about 3AM. I would start with new ones. Buy a programming tool (about $12) and confirm that you can link to all of them before installation.

It's those F-ing electrical Gremlins that come free with all C6s. As long as you have a car battery that's under 2 years old, and your TPMS sensors are fairly new too... You just have to put up with Mr. Gremlin. However, if the exact same warning light keeps popping up often, probably the TPMS sensor needs replacing.

So it happened again, it sits in the garage for weeks at a time, Same one LF, says 0 flat tire ,I am assuming its a bad TPMS sensor, will look when I get it replaced, They where OEM but who know the date codes, My dealer sucks but a different issue...
Ordered a relearn tool will be here tomorrow, Will it really limit me to 55 or is just a nanny? Tire Pressure is 32 like all the rest of them. Getting a new HU installed tomorrow so I know it will have to be relearned, But I want to be able to drive it to the shop, its 15 min away and 5 min i s freeway speeds... Hopefully the new HU wont be too bad on the part that shall not be named , DMH-2660NEX Best Buy says yes, Crutchfield say no well see...
Thanks

EMI problems typically result in a warning 'ding', a DIC message "SERVICE TIRE MONITOR SYSTEM", and the tire icon lights up on the dash. If you try to display the tire pressure on the DIC, one or more of the sensor positions will display XX or XXX instead of a numeric value. The fault usually clears after you shut down and restart. I've had this happen a number of times, but it sure didn't limit my speed to 55 mph or anything close to that. A flat tire / zero pressure warning is a different animal. I could be wrong but I think some of the high end TPMS programming tools can command the sensors to display their battery condition on the tool.

Long story short, While waiting for the relearn tool to arrive, had to go drop off the car at BestBuy, Put it in ACC mode , hit both lock unlock , waited for beep , shut it off , restarted it issue gone ...
Never had to relearn ... Will keep the $10 tool when it gets here ... Hopefully new radio has no interference ... Had them put the a cigarette lighter USB connection in the center console. Also splurged for the backup cam ...
