So last week I put new tires on my Jeep - 315/70/17's on a set of Rubicon rims I had at the house with TPMS in them. All was well until today, driving home from the store, when the red light above the temp gauge started flashing a bit of ways into my drive.

This light flashed once before for me when I disconnected the plug for the 3rd brake light, but then went away when I plugged that back in and has never come back.

Is it related to my new wheels/tires or something more ominous? Is it because I haven't used a ProCal to set my new tire height (2" bigger)?

Thanks!

Just checked DTC codes with the "key trick" and nothing came up. I've got to believe this is related to the new tires (the latest change on the Jeep) but wondering why it took almost a week to show up. It is colder today - don't know how that could be related though.

 

The unlabeled red light is the Sentry Alarm System, or something like that. It comes on during the bulb check, then goes out after the engine starts with an accepted key. If it stays on then (engine start), your Jeep will be disabled and die. If it comes on at other times, it needs to be checked by the dealer lest it break hard and leave you stranded. This is in ***ALL*** Jeep brand vehicles and is unrelated to other alarm systems.
