Message: See Manual (2017 GT350)

[americanaut]

Dear all,

I'm new to the forum, as I recently purchased a 2017 GT350 on the spot after a test drive. It's a Canadian car that was imported to Switzerland, as they were never officially on sale here.

Anyhow, on that test drive already, the orange wrench with the message "See Manual" came up, but also vanished again. I asked the seller (importer of cars from the US/Canada) to take care of this, which he said to do. As I picked up the car today (it needed to be homologated according to Swiss rules), the message came back up after a few minutes of driving. I called the seller, but he just said they had a look, everything seems fine, "service life" is 80% away from a service, oil is new and so on. There's nothing that they can do. Well, at least they could have told me when I picked the car up...

Anyone any idea on what the issue could be? The message pops up, vanishes, comes back up after a few miles, maybe stays for a a minute or just a few seconds, vanishes, might be gone for a few minutes even, comes back up, and so on. Really annoying, especially as I have the speedometer shown in the display.

I already searched the forum, but only found messages that seem to stay. I hope it's just a connection with a hickup... According to the manual, the message indicates a malfunction of the powertrain - car runs, pulls and shifts absolutely normal though.

Can a regular Ford dealership (which never sold any Shelbys) ran diagnostics on it, or would they need specific tools?

Thanks for any helpful input, as I can then maybe guide the mechanics to a specific part.

They can run a diagnostic, but if the wrench isn’t currently displayed, I’m not sure if they’ll see a stored code or not. It may be worth it for you to carry a code reader with you (wired or wireless) and check codes as soon as it comes up. I also recommend a code reader that supports advanced diagnostics. I have a few different Bluetooth readers, but this is my better one that’ll run dianoistics on all modules: https://www.amazon.com/BlueDriver-B...ocphy=9016164&hvtargid=pla-405661045648&psc=1

Best of luck!

You should be able to take it to a Ford dealer and have them check it out, if it's throwing any codes they should be able to read them.

What I noticed is you'll start seeing phantoms things like that and it could just be a sign of a battery waiting to fail (nearing the end of its life).

Definitely take it in for a proper diagnosis.

agree with the above, given it's 4 ish years old, try a new battery first. battery and alternator issues make all sorts of codes come up.

Thank you all for the first inputs, I guess I‘ll have the mechanics look into the battery first then.

Alright, a little update as this might be of use to other members with a similar issue. My problem seems to come from a faulty transmission oil temperature sensor. That was one of the codes. After the codes had been cleared, the message only appeared once for a fraction of a second. Also, I was able to monitor transmission oil temperature in the gauge cluster, it went up and down (and kept doing so) about 100° C (ca. 212° F) in split-seconds, which cannot be at all, as the car was just warming up. So the mechanics assume a faulty sensor, which would make sense. We'll take care of this soon.
