So my 2012 FFE recently turned 5 years old , and I got my first SSN message two weeks ago .
My car had the wire harness modification and software update completed as soon as I got the recall notice last year.
I received the SSN message just after unplugging (it had JUST finished charging), turning it on and putting it in reverse. Along with the SSN message, it also had a yellow wrench with a message about a starting system fault (I think - it flashed very quickly and only once). I turned the car off, waited a couple of minutes and turned it back on and the messages were gone. I made a service appointment right away, but couldn't get to the dealer until today.
After approximately 8 hours of diagnostics and taking apart various components, the dealer determined that the cause was not related to the outstanding wire harness replacement recall (they said it was not the correct error code for wire harness). I was quite concerned at several points throughout the day because I could see error messages on my app, including a red "battery health" message. It also mysteriously stopped charging twice during the day, but I think the technician may have not turned the ignition off after plugging in.
Just wondering if anyone has had a similar problem? Here are the technicians notes on the repair order.
"Story: 53941 recall 15N03. Print off and go over recall. Scan system, came up with wrong code for recall, continue with normal diagnostic and repair procedures. Has 2 codes for TCM P1A0A:01-48 P1A0A:29-48. Run pinpoint test A1 through A5. Passed. Clean connectors at TCM and PCM. Reassemble and retest. Remove left inner fender for access to PCM. Bolt seized in PCM box, cut box cover off to gain access to PCM. Clear Codes, and road test, recheck system, passed"
Cut box cover off to gain access to PCM. Yikes.
From what I can gather, they did a lot of poking around but did not find the cause. Which is worrisome. Very. Any technicians out there who can translate the error codes and work order? Any similar experiences?
