Ford FJDS Error
Posted to Technical Tips Forum on 10/21/2022 5 Replies

Just putting this out there, I'm not sure how common this issue is. We had the above vehicle in for a PCM replacement, and after programming with Ford FJDS, the vehicle speed in the PCM was displaying about 4 times too fast. Turns out the software was decoding the VIN as a 2002 vehicle. At first, I wasn't sure how to correct the problem, so I called the support number on Ford's website and talked to one of the most unhelpful reps ever, who insisted he couldn't help me, and that the problem couldn't be in the software when in fact it was. Anyway, I finally tried entering a new programming session with the key off, so the software couldn't pull the VIN, and at that point it allowed me to enter the vehicle info manually, and I finally got the correct software programmed.

If there's anyone on this forum who has connections with Ford's software engineering, or whoever it is that's responsible for this type of issue, maybe you could pass the information along so the next poor guy doesn't get stung by this.
