You can do it DIY through a Forscan beta that allows for firmware/calibration updates. Stupid simple process and takes less than 5-10 minutes. Hi, just wondering if you were able to post that. I tried hunting it down by looking at your profile but didn’t find it. Is it easy to perform? I’ve read other posts that say the problem comes back even after a dealership performs the TSB.

I haven't unfortunately. Had a lot of changes with my #dayjob situation the past couple years that I haven't had any free time to dig in to C-Max related stuff I've wanted to do. I have a long todo list built up already. lol. The update is pretty easy and quick. You just need access to a Forscan version that has the ability to do firmware updates (or Ford's IDS/FDRS and a compatible adapter). I believe you need to reach out to their support team now for that. Not sure. But you'd just go to the ACM firmware update pane and it should show available updates that Forscan has documented. The entire process takes under 10 minutes as I recall. If there are any concerns about health of your 12v battery, it's probably a good idea to put a battery tender/maintainer on it capable of at least 8-10 amps output. During the update process by default it shuts down the rest of the vehicle so the DC-DC converter (or EVSE if you have an Energi) should not be relied upon. I'm curious about the comment about the TSB though. I haven't seen those same comments/posts. Got any links? I'd be curious if the proper module was not done and maybe the ACM was confused with the Sync system? Edited 15 hours ago by cr08 Quote Link to comment Share on other sites More sharing options...
