Yeah, I was mostly curious if anything existed. I'm actually surprised there isn't given the more complex cooling system. The only thing 'complex' about the C-Max, at least for the Energi/PHEV variant, is the electric coolant heater, isolation valve, and aux pump on the ICE side so it can have...

Just a curiosity, but has anyone reviewed the service manual for these to see if there's a specific procedure Ford has already programmed for this? I know on my C-Max in its service manual there's a special procedure involving some 'pedal dance' shenanigans to allow it to cycle coolant through...

It can definitely be done, even DIY'd if the dealer refuses to do so. There's a lot of discussion and research that was done on the C-Max at the forum thread linked below. Electrically it is the same as the Focus/Focus EV. Many owners (myself included with a '13, which wasn't in Ford's approved...

So going around other communities who have went through this whole 4G TCU upgrade mess and checking in. Got this message on my C-Max this morning. Curious if anyone on the Fusion/Focus BEV side has received this yet? "Due to software updates to the Fordpass app, preferred Charge Times...

Also absolutely do make sure you don't leave without verifying it works. Part of the bulletin has provisions for working with the customer to set up the app and ensure it is working.

This is the other screen I was referring to. Again, this seems to only be found on the 17/18 C-Max models which have a completely new IPC part # and there were a number of additional changes on these. I don't know if the Focus EV ever received the new part # (mine is HM5T-10849-AC) or not. This...

Yep. The cluster one is the one I'm referring to per the photo attached. From the way some of the comments were worded, I was curious if you guys had this function from the factory. It's not enabled on the C-Max but is available as an AsBuilt option in our IPC. 2013-2016 models it just shows...

Yep. My C-Max behaved similarly. I keep my VC set to start at midnight every day of the week and end at 8am (if it takes that long or if I start charging later. L1 usually only takes 5h30m or so on an empty battery). There was a point recently where it kept charging the moment I plugged in...

Definitely let us know what the new calibration level ends up being when/if you get those updates. It'll be really helpful to a lot of folks in the DIY space. We're all patiently waiting for someone to get these updates and report back so we know what files to look for.

Yeah, there was no indication it was Canada specific when it was posted over on Discord. And at least as far as the firmware/hardware stuff goes, that's all North America-wide so it would apply to both countries anyways. As hinted at above, supposedly the previous TCU models have new updates...

Honestly I'm not too surprised that you got that answer. From what I've seen between of this whole upgrade mess and how Ford's IDS system works, most techs probably have no clue what calibration levels are used beyond 'whatever the latest IDS pushes' as it isn't really front and center. Most of...

I've been keeping tabs on the Motorcraft site to see if anything new comes up for the H models and the calibration level HJ5T-14G087-UP that KP19 mentioned above is the latest I have found. This is also what I have on my DIY install on my 2013 C-Max. The timestamps on the files show around...

This seems to be going around. Already seen it myself on my C-Max and a few other C-Max owners have reported it as well. Likely just a temporary glitch.

I'm not terribly familiar with the layout of the Focus Electric, but there could be a REMOTE possibility they could have dislodged a wire somewhere related to the antenna? I believe on some Ford vehicles they have power going directly to the antenna on the roof for amplification. Though the...

The TCU upgrade wouldn't have affected this. The HD radio signal comes through the same FM signal and your ACM/FM tuner which is also a separate antenna feed from the TCU. The messages you are seeing simply indicate it can't get a solid lock on the HD signal. Depending on the station you're...

At this time at least on the C-Max side the move from UM to UN doesn't have any visible/noticable changes. Just an FYI. Ford has basically halted these modem upgrades to fix some software issues on their end regarding all this.

Given the location of the TCU in the various vehicles, I have a feeling an induced current isn't the issue. But just a guess on my part. On the C-Max, the TCU is located behind the driver side D pillar panel up close to the rear window and away from any heavy current devices. The Fusion's have...

I don't have the exact DTC in front of me. I can try to pull that later this afternoon. But it is for an open circuit or ground on the antenna. But that's the only code it reports. It does come back if you try to clear it as well. FWIW, I intend to try to retrofit a 'kitchen sink' sharkfin...

This antenna you linked is the same one I have installed in my C-Max (and used by some other Ford owners) and can confirm it works and gets a good signal even with the long cable. Haven't had any signal related issues with the 4G upgrade, just that harmless DTC.

The DTC for the aftermarket antenna is harmless and works 100%. I can personally vouch for this as well as other users. The TCU still gets a solid signal. That said, here's the part numbers as well as a link to the related thread on the F150 forums where much of this has already been covered...
