After doing a search most of the threads I've found have to do with issues from aftermarket tires and wheels. I just picked up my 08 Sahara today and while driving it home I noticed the TPMS warning light was on. Once home I let it cool off for about an hour and checked the pressure in all the tires. They were at 36-37 psi on my digital gauge. After taking it on a 30 minute drive at over 45 mph it hasn't reset. Is there a quick way to reset, like pulling the battery cable or something? My dealer said they would fix it if it wouldn't reset but I just got it and don't want to give it back to them just yet.
Thanks,
Mike

 

Did you check the spare? That will set it off too.

 

Yes I did check the spare and it was OK. BTW the manual says the spare can be low and NOT set it off. Only the tires on the road are monitored.

 

when you finally give up it will reset. It's not monitored very often....

 

Gee, thanks. BTW I read the disclaimer in your sig.

 

certainly no offense intended. Anything I suggest is just that, a suggestion. And yes a disclaimer is in order here, you will see after you've been on here a while. If I stubbed your toe I certainly apoligize....

 

None taken. Your reply is actually what is supposed to happen. Once you drive it for more than 10 minutes over 15 mph it should reset. Mine blinks for 75 seconds and then remains solid indicating a system fault.

I'll call the dealer today and see if it's something they can do in less than an hour. I've never dealt with dealership before but they seem ok so far. My salesman even said he'd send someone over to pick it up.

 

I have the same system and the spare always sets it off on hers. Had the dealership reflash to 28 PSI and no problems since then when it gets cold outside.

We also have had the stems replaced under waranty before because they are very fragile.

 

Here's the latest. Stopped by the dealer today and they tried a reflash and it didn't work. They told me they had to order a new module. I'll follow up with details when the work is complete. Thanks for all your ideas.
