Sounds like they're more willing to try and fix the problem through engineering and OTA means than having customers get angry over leaving their trucks at the dealership for days or weeks because technicians can't follow directions
I'm the one that checked your truck before. I have the VIN. OTA Fluffline lied to you. You were not sent an update yesterday. I'll look at it again tomorrow when I have full access to refresh my memory on what the dealer did, but I found my previous post and based on what I said, your truck is not stuck. They just haven't sent you anything yet and they can't manually push an update to you.
Unreal is enabled with 3.5.3.2? Or just cosmetic changes? It didn't stand out to me as being sharper.
No there is not much info in Ford’s notifications for their OTA updates. No mention of the full screen CarPlay that was added with my 3.5.3, which I thought was one of the more popular features. Only trumpeting Alexa….
I thought it was based on a previous thread. I could be wrong. I'm sure one of the experts will chime in soon.
You have to make a small edit in Forscan to enable the Unreal engine
That's what I thought.
Have you confirmed your truck has been sent 3.5.3 and you're also waiting on it to install?Over the past year I have seen my truck go into the dreaded "deep sleep" mode here and there. I have also experienced delayed software updates. I have a BM2 battery monitor on my boat and decided to buy a second to keep tabs on my truck battery. The BM2 hooks directly to the battery and records voltage locally for ~10 days. When connected via bluetooth, the data is synced with your phone via the BM2 app. Very useful tool and less than $30. Check out amazon or other online shops if interested.
I hooked it up a couple days ago and already seeing some odd behavior. In the image below, the first red arrow on the left was at ~ 1am where the voltage dropped from 12.6V to 12.4V for no apparent reason. I recall reading that these trucks require 80% SOC for updates to download/install and 80% on a 12V AGM battery is 12.5V. I am wondering if an update was triggered but ended up dropping the voltage too low resulting in an error and aborted download/install. A similar drop happened later in the day around 8:15pm (right red arrow).
The two white arrows show a different pattern with identical behavior with an initial drop to 12.17V followed by a slight recovery, then a second dip and back to steady-state around 12.6V. I am thinking this occurs when I walk up to the truck with keys and the truck wakes up (clicks and lights turn on). Such a drop from 12.6V to 12.1V seems excessive for the truck just waking up though. Perhaps this is a sign of a faulty battery, but oddly enough, there is no hesitation when starting the engine.
The spikes up to ~15V are while I am driving and battery is being charged by the alternator.
I'll continue to monitor but may end up just trying a new battery as some have recommended.
Yes, they replaced your TCU and properly programmed and updated it. You sync version is v4.0.21233 which is past the hump where trucks get stuck. You are most likely pending some of the older OTA's which don't get sent out by Ford very often. This is why your dealer told you "wait and see". They don't have the ability to push OTA's to your truck. Nobody does.
What were the symptoms and what did you do to correct?
