Gremlin in the Jeep

so it seems like there is a gremlin inside my jeep's computer thats just there to annoy me. I wanted to see what you guys thought about it and if its worth attempting to get it fixed or just live with it. I have a 05 Grand Cherokee Limited 4.7 L with 85K miles btw.

So first thing it does is flash the service 4wd light on every once in a while. It will come on randomly for a few sec then go away. Only does this every few thousand miles and does not throw any codes. I know there is a TSB about this that upgrades the software but I never went to have it done. Anyone know how much it costs and is it actually worth it? Will it harm the jeep if I just leave it alone?

Also yesterday I was driving home and the Tire Pressure Monitor warning light came on for a few seconds and went away. It did this twice on the way home and hasn't done it since. Yes....I checked the tire pressure and it was fine so any thoughts? First the service 4wd message came on for a few seconds and then a few min later the tire pressure monitor light came on for a few seconds and went away. You think they are related or just a weird coincidence?


I'm thinking these are just glitches in the software and won't affect the driving at all....what are your thoughts? Worth attempting to fix or no?

I think it is glitches as well. But....you could have a battery starting to go, corrosion on the battery, abs wheel speed sensor going bad and a tpms sensor going bad. I would clean the battery terminals and lube them with the battery grease.....just to be sure of that. If any of those things are going bad...all the lights will get more frequent and it will eventually pop a code. I think your good though
