Hello, I am trying to replace my SJB (Smart Junction Box) due to the inevitable water intrusion and corrosion. I am having trouble finding a new replacement module. There are plenty of used ones on Ebay, but they all look to have corrosion as well. My issue is finding a new replacement with a matching part number. The SBJ currently in the car has part number 4R3T-14B476-BS. I called Ford to get a part number using my VIN and they said I should have an SBJ with part number 4R3Z-15604-DA. So the current one doesn't match up with what Ford says I should have. I am unable to find either of these part numbers on multiple sites. I did however find a new one on FordPartsGiant.com, but the part number is also different being 5R3Z-15604-DC. So my question is am I able to interchange the SJB with another model number as long as it is for the same year, engine and transmission? Not sure if anyone has had success in doing this. Any help is appreciated. Thanks!

You won't be able to buy a new SJB. Older vehicles more than about 5 years old or so won't have the option to buy a new SJB or PCM. Used or any "rebuilt" ones are all that you'll have now. If yours is salvageable then your best bet is to send it out to a reliable module repair service.
The Ford parts catalog # is going to be different than the Ford engineering # that's on an actual part. Unfortunately, there is no public database that I know of to check the #s with each other. The catalog part # that the Ford dealer gave you is really only useful for buying a new one which you can no longer do.
Your current one is likely the original and is likely the right #. It's just that the parts department likely can't tell you what engineering # you should have on the part. I really don't know why Ford decided to make a numbering system with two different part #s for every part that they make but nonetheless there it is.
Different models, trim levels, and options will dictate which SJB you need. A base model will be different than a Premium and a v6 will likely be different from a GT for instance. Sometimes Ford will supersede a part # to a newer part # that replaces it but it's hard to say which #s are compatible unless the dealer tells you what each of them are.
The 5R3Z-15604-DC on Ford Parts Giant is also unavailable and that seems to be the right catalog # but again that's not the # that will be on the part itself even if you did find one. If you got one new in the box then that catalog part # would indeed be on the box that it comes in but not on the part itself.
Send yours out to Automotive Circuit Solutions, Autoecm, Upfix, or Module Master since they seem to be reliable module repair services to use.

How to Decode Ford Part Numbers - Blue Oval Trucks

Overview: Ford part numbers are divided into two main categories: Engineering Numbers and Service Numbers. The engineers will design a part and assign it an Engineering part number, which is an alphanumeric reference code used by the assembly plants. When … Continued

That link is useful to understand specifically how the numbering system works. That article describes what I said above and then mostly delves into the particulars of how to dissect a part # and translate it. However, that's really not going to help him in his quest to get another SJB since he won't know which previous catalog(service) part # revisions will be compatible unless the Ford dealer tells him all the superseded part #s and also then gives him the corresponding engineering #s. In all the years that I've asked I've never had a dealer able to give up any details at all about the engineering #s on the parts themselves.

Email or call this guy. He helped me out on a powerstroke getting part numbers for miscellaneous o-rings in December. He is the computer guy not really sure if in parts. But either way he worked on it and sent me detail diagrams for me to pick from to get the correct part numbers.
He may help you out in updated and/or parts numbers.

Any of those module repair services I listed will have the info that you need. They will have a database of the correct PCM for your car and especially when you send them yours they will know exactly what's compatible. As I said get your module sent out and fixed. If they can't fix it then they will let you know but it will be much cheaper to have yours repaired than to buy a rebuilt one and you will have your original PCM.
Engineering #s will not be available from a dealer. They can only give you catalog part #s which won't help you identify an actual part via its engineering #.

Thanks for the info Cobrajet67! I was able to find a new one for sale in the box from Ford that someone didn't need and they are local so I can verify it is actually new. It is for a 2005 V6 coupe with the automatic transmission, so same as mine. I am lucky to have access to Ford IDS and am pretty sure I should be able to take the programming from mine and install it on the new one. If it doesn't work then I am out a little money, but I was able to get it for a great price. If it does work however it might be helpful to others to know if it's possible to program SJB's of similar model years. If all else fails with the new one then I will send mine in to have rebuilt. I appreciate the info on where to send mine if I end up having to go that route! Thank you also Roachwe for that info! That will come in very handy. The part numbers can definitely become confusing on some of these when trying to find replacements.

You got incredibly lucky that one was sitting on a dealership shelf somewhere. If it's the right part # for your car my understanding is that it shouldn't need programming.

You can use the same procedure in this video to re-program the SJB.

Yes! I was lucky indeed. I got the part last week and finally installed it today and it worked without me having to program it. It's nice to finally have a good one in the car and have things working properly again. Just gotta reprogram my key fob, but that should be pretty easy. Appreciate all the info you gave me. The disadvantage of a project car is finding the time to work on it, but it's fun when I do.

Thanks for this! Any videos showing how to use the IDS for programming is helpful.

Thank you for this content. I am also looking for a SBJ for my 2006 GT convt. Do you know of any shops that will refurbish the original SBJ?

Pro-Tech Auto Systems, Automotive Circuit Solutions, Autoecm, Upfix, and Module Master have been talked about on here to have been used before. Any of these qualified module repair services will typically have your original module that you send to them fixed in a couple of days and expedited shipping is available both ways. Some companies don't yet offer repairs on newer modules but I think most places repair them for the 2005-09.
Take pics of the module that you send to them and tell them not to paint it which some places may do.

Is there a thread I am missing...I need a Module repair Service for a Ford Base Mustant Anti Theft Module 5R3Z-15604-DC. Thanks in advance
