APIM Failure

[rodneyfrix]

My daughter’s 2018 Mustang started having issues with the screen going black. It was random. I suspected APIM so took to local dealership. They ran diagnostic and said it was acm not the apim. I ordered used acm and installed. Took back to dealership and had them program. Everything worked good for one day then started intermittent black screen again. Took back to dealership for diagnostic. This time they said apim failure. They said the part number I need is JR3Z-18C869-EA. The actual part number on my apim is JR3T-14G370-ABH. I am tired of messing with the dealership and was hoping you could tell me which apims would actually work in her mustang and still keep same features. It is the large screen with carplay, nav and sirius. I have never used forscan but could attempt if programming is needed

They said the part number I need is JR3Z-18C869-EA. The actual part number on my apim is JR3T-14G370-ABH.

One thing I'd add is that Ford uses what are called "Engineering" part numbers, which differ from the actual "Service" Part Number that the dealer will use to look up parts or match to VIN.

These Engineering part numbers are usually printed on the actual part itself; meanwhile, the Service Part number used for parts lookup may not be. Some parts have tags or stickers on them that may have the Service Part number, but most don't.

It's a bit confusing, but wanted to point this out, in cases like this where the dealer is saying the Part # is X, while the actual Part from your car says Y - the dealer should be correct, especially if they use your VIN to verify.

Some more info for context:

Engineers will design a part and assign it an Engineering part number, which is an alphanumeric reference code used by the assembly plants. When the part is redesigned, the change needs to be noted so the Engineering part number is changed.
When the part is released for service it is assigned a Service part number. It is a different number, because how a part is finished and packaged for service is different from its original production counterpart. (It’s the number used by your Ford parts man to look for your order. He doesn’t want to know about the engineering part number.
However, you may need it because the engineering number is the one appearing on many parts.) This allows Ford Parts and Service to track changes affecting interchangeability by modifying the Ford Service part number. The Service part number will not change with the Engineering part number unless the change affects interchangeability.
Therefore, the part numbers on the part are generally Engineering numbers while the Service part number will be on the box. There are some exceptions, such as a whole grouping of parts or a kit. Engineering and Service numbers decode the same way. The difference being the fourth character of the prefix.

Thanks. The part number that I said is actual is from the label on the back of the apim. I didn’t find the number they gave anywhere on the apim

Np - right, which means the JR3T-14G370-ABH is the Engineering Part Number on the part itself, which will not be what the Dealer sees - the Parts guy will tell you the Service Part Number JR3Z-18C869-EA.

What you said makes sense. I am looking for a used apim and the only part numbers I see are those that are printed on the apim. Is there a way to decipher the part number for features?

Million dollar question.
I've used this site in the past:
https://www.fordpartsgiant.com/part.../electrical/audio_equipment_original_fit.html

(I've filtered for 2018 Mustang Audio equipment; scroll approx 1/2 way down, you'll see ES7Z-14D212-DA as an example of one APIM. Scroll approx 3/4 of the way down, you'll see JR3Z-18C869-EA listed among the ACMs, among many other Service Part#s, and various feature descriptions which may not be "user-friendly" in typical OEM fashion)

Basically, you can search by VIN or enter model year and model; the latter should make the filtering less specific, and list out all possible service part #s for that model. It also shows a description.

If you search by VIN, theoretically, this should only show the parts that fit your car.

Overall though, this site doesn't claim to be 100% accurate. Sometimes the filtering doesn't get specific enough, depending on the car and part being looked up. I can attest to the accuracy not being guaranteed. However, it's a good resource for info.

EDIT:
I can't guarantee of course, but based on your feature description (2018 Nav, Sync 3, Carplay), it seems that, if talking APIM, the following Service Part#s are closest to your car:
JR3Z-14G371-C
JR3Z-14G371-CEA

If you compare Ford's cryptic descriptions for both back to back, the only difference appears to be production date range of the part.

Thank you. I will take a look

more than likely, you will need to use forscan to program the apim. i didnt have nav but ordered an apim with nav, it came from an f250. the nav worked out of the box but i lost my heat and ac controls from the screen. entered all my as built data into the apim with forscan and everything was back to normal but obviously lost the nav menu. went back in an enabled nav and everything is working as it should
