Thanks for your wish. With God's help, I hope it will last 10 years, after which I will buy a new PCM. Greetings Victor.

My problem is the same. There is no 5v power supply from the PCM module at 17 pin on the black socket and 31 pin on the white socket. This proves that the PCM module is defective. I found a solution to the problem on YouTube again, here is a link

I hope I have contributed to solving the problem.
I would like to thank everyone on the forum.

redsniper Friends thank you very much for the advice. I ordered a new PCM module from Auto101 California. It will arrive in Bulgaria on July 15. I will install it and write what happens to the car. Greetings Victor.

There's more to it than just programming a vin, and no need to program Kilometers or miles in the US as this generation of pcm module doesn't store that information.

That last two can be anything from AE-AJ, that's just a revision of software that gets updated to latest version available from Chrysler Tech when it's programmed to your Jeep.

You can mail a matching part number pcm to me for flashing if you need help getting that done.

Bigrigr Module number can have many different combos for the letters at the end, its only the actual number before those letters you are concerned with. @Waterluvr can explain more on this, and can help you with a replacement if needed...

I tried to open the PCM module to check for cold solder, but the whole module is covered with some jelly like strawberry jam and I can't take it out of the case.

And I think so, I just don't want the situation to develop like that. I will do a few more tests to confirm the diagnosis.

Taking a connector out and putting it back cleans the contacts.

I usually smear a little normal car grease on the plug when I put it back for the last time.
Yes, of course, all three PCM jacks were removed, cleaned with a contact cleaner, and then installed. There is no change in the behavior of the engine, it goes out again.
