how would you diagnose if your computer has gone to crap?

what are some symptoms?

 

I believe but not 100% sure that if you pull it out and take it to some auto parts stores or a dealership then they can check it out for you. I would call up your local dealership and ask to speak to someone in the service department, and they should be able to tell you.

your dealership can check it but I don't think you need to pull it if you can drive the jeep
