Long story short... airbag light came on 3 weeks ago, then the battery died within 2 days. It was an old battery so I bought a new one and dropped it in, and did the 5x headlights 3x brake 'trick' to reset things, assuming that was sufficient. This week, the airbag light came on again, but this time, the new battery died yesterday. I jumped it, ran it for quite some time. I hadn't bothered to check codes before this, so I grabbed my OBD2 cable & started up Forscan. There were a number of codes, but only one present at the time of request. I figure the others came up due to the battery dying. So I reset the DTCs and just one code continues to come up: U0413 Invalid Data Received from Battery Energy Control Module 'B' (from the RCM) It seems like the BECM 'B' is busted and drawing current when the vehicle is off, because... I also used Forscan to check the Battery State of Charge last night, and it was 99%. 8 hours later: 70%. I ran the vehicle for about an hour or so and it was back up in the 90s. I searched U0413 and found one other thread on this forum, but that person also had a bunch of other errors and their issue seemed to be the RCM itself. The BECM 'B' module looks to be PN HU5T-14G490-AF or HU5T-14G490-0C and it's like $70 new or $35 if I take the eBay plunge. So, the questions I have for the other owners here, are... Do you think my BECM 'B' is the root cause? Or is it failing because of something else (like a short? ugh... I hope it's not a short...) Where is the BECM 'B' located, exactly? I'm cool with tearing some things apart to get to it, but I don't know where to find it... Is the BECM 'B' a plug & play / drop & replace type of part, or does it need very specific programming for my specific make/model/VIN/etc.? Since the RCM is shooting the BECM 'B' communication error, should I be worried about the RCM/airbags/SRS? Am I stuck with needing to take this to a dealer? Thanks in advance for any suggestions or insight!

Hi all. I’m new here but I’ve been lurking for some time. I have a 2019 Edge Titanium with about 85k miles. No warranty. No extended warranty. No DTC codes to speak of. I’ve only had it for a year but it’s been bucking/surging for most of that time. I’ve read through this thread and the Ranger forum threads on this issue, and I’m about to start trying to address it, bit by bit. I fear I will have no success in the long run, but I’m trying to stay positive. In no particular order, these are the areas I’m going to focus on, for better or worse. 1. Transmission fluid. I don’t think the original owner ever changed it, so this is near the top of my list for the next week. I’ll ask the shop to drain and fill twice if it still comes out too dark. 2. DPFE Sensor. Seems like a long shot that this could truly be the culprit. I have one arriving today from Rock Auto. I have the tool to disconnect the hoses so this should be fairly easy to tackle. edited Aug 10: changed DPFE. Bit of a pain to get those hoses loose but otherwise it was easy. Unfortunately, no notable improvement for me. 3. Related to the above, the EGR Valve. I want to peek at it and see how dirty it is. Will clean if possible and replace if absolutely necessary. 4. Throttle body. Not saying this is remotely related, but the TB in my old Fusion had gone out and so I was thinking about the one in my Edge. It’s easy enough to pull out and clean safely, so I might as well do it. No indication that this is actually defective, though. 5. PCM firmware. In February, I paid for Forscan and flashed the PCM. Risky shit, and probably better to have a shop do it. I do not recommend doing it yourself and am not responsible for anyone who does it. Anyway, it went fine, but didn’t fix the issue. Just noting it here since there have been a few TSBs about that. According to Forscan, I still have the latest version. 6 - 98. ¯\_(ツ)_/¯ TBD. Any other things I am missing that others have tried. I don’t recall them right now, but I’ll try just about anything, up to… 99. Torque converter. If it comes down to this, I’m probably just going to sell the car. At this point we’re talking about a major replacement I can’t do myself and hours upon hours of paid labor. Will let you all know how it goes, but if anyone has any other recommendations, feel free to reply and I’ll add it to my list. Also genuine thanks to Robert for fixing the login issue so I could post here
