Hi, My Cherokee has 99K miles, mainly used for city driving and has been very reliable for me.
The only problem I currently notice is the radio sometimes reboots a time or two after starting the car.

No check engine light comes on but I plugged in a higher level OBD2 scanner to see what it finds.
I first cleared the codes to make sure there wasn't anything already fixed in there and it seemed like a lot of them....
But much of the codes quickly returned.
Here is a screen list. I need help deciphering and wondering why it looks like there is a lot of problems. Perhaps they are all related to one component?
Anyone know?:

 

location, location, location, location, location, location, location, location, location, location, location

fill out the rest of your info if you want help.

 

ThankX Done! Feel like I'm going on a date or an audition now ! )))

 

you live in a state that snows so most likely it has rust.

from all the error codes it looks like an electrical issue.

start with the easy things like fuses, check that your battery is fully charged, but my guess it's most likely going to be a bad ground due to rust or maybe a wire that that has been stripped and has corrosion.

look for the wiring diagram and look to see what wiring or ground all those modules have in common.

 

Stick your head under the front drivers side and have a look at the ground strap that runs from the trans to the frame. If it's all green then it's a pretty easy job to replace it. https://www.jeepcherokeeclub.com/thr...y-step.250148/

 

ThankX!
I'll try to get to checking it this week and update here!

Take care
