Monitoring the BMS (device on the negative terminal of the 12V LVB), I happened to get a first record before a 12V Fault - service Fordpass message. By luck, I got an OTA event at the same time (Ford Power-Up 2.1.0). Probably best if I explain events first, fortunately with Ring camera in the...

In the unlikely event that someone's MME is out of commission for lack of LVB availability, I now have two extra Motorcraft 12V BHAGM-H3 batteries. This is not a for sale ad, I can use them for various back up applications, not to mention having one as a spare myself. One is "new" Motorcraft...

Jan 8, 2022 updates SOBDMc, SOBDMB, PCM, running the first one, SOBDMC runs the other two automatically in sequence. Took about 10 minutes. 1 peddlers beware backing out of the garage, it turns off 1PD. After done, (Dec. 2020 FE), all that remains stuck on my FDRS SW Update list is ABS. I...

Previously, I was asking about the optional second longer setting in our battery tray (accidentally posted to batteries in marketplace). @kram recently reported that he found that a Chevy Spark AGM battery works in MME. I did some googling, this AC Delco part LN1PS is quite interesting indeed...

First look at a MME LIN BUS device for me, I will update with information as I learn how to decode this first example. Tapped into the BMS LIN BUS here, but starting a new LIN dedicated thread. This will be of limited interest to most, but maybe some more general things can be learned, such as...

Since I did the last update Nov. 19 ( Customer Satisfaction Program 21P22 - Software Calibration Update ), I noticed two updates tonight, ABS and DSP. I am sure that everyone doing the 21P22 update now is getting the latest ABS update (and, it may not matter). (I suppose the version may not be...

Noticed a number of new updates in FDRS this evening, November 19, 2021 (actually went out to some FDRS data logger work). As @breeves002 always cautions, there may be no need to do any of these right away, or ever. I started at 5:25 pm. It was going pretty fast (under 1/2 hour), until the...

The KONNWEI KW710 BATTERY TESTER arrived this evening. I scanned the manual, connected the cable, and tested the new Mach E - BHAGM-H3 12V LVB. The KW710 is powered entirely by the battery under test, there are no batteries to install in the meter. It all took a few minutes. Tested in the...

BHAGM-H3 12V LVB Measuring Internal DC resistance The internal resistance of the battery might be a good indicator of aging or failure. There is AC internal resistance, usually measured at 1 kHz, and DC internal resistance. This post tells about DC internal resistance measured at 1A and 5A. To...

It looks like the 12V battery tray has been built for alternative LVB battery sizes. Maybe it is just a standard Ford part used in other models? Does anyone have AGM 12V experience with sizes near ours, is there a standard size, just one size up from 35 Ah, about 1.25" longer? See second...

Spent a few minutes looking around FDRS after today's TSBs were done. Came across BECM battery cell voltages. Here is a sample: (click on the pic for a larger image) (FE extended range, 4,468 miles) 98% SOC, not sure why it blew through my 80% charge limit last time, which almost always works...

Loaded my 2 month free FORSCan key and just got in a half hour or so exploring (newbie level). FORScan connects easily and every time to MME with Mongoose, I see no compatibility issues so far, with either FDRS or FORScan. I do not yet see how to view the module code in FORScan, either...

I had read somewhat that one could look at PIDs with FDRS, but was so focused on module update, Day 1 I did not see it. I just got a couple of hours to continue my exploration of FDRS this afternoon (Day 2 of my $50 rental) and discovered flight recorder. Here are some sample screen shots...

Powered up the MME with a flash programming power supply, Ran FDRS on a Lenovo Thinkpad with the MongoosePlus Ford2 $495 from Amazon. All went well, no problems. With a two day $50 pass, checked all modules, and under SW update, updated three modules. The instructions from Drew (the Mongoose)...

Another minor complication. The Ford MME SSM and TSB just say to connect a 12V battery charger. When my dealer programming was clearly going to run hours overnight (which it did), before leaving, I reminded the tech of the 12V battery drain, and he wheeled over and connected a giant 12V unit...

Ford only updates modules as needed by specific problems and satisfying a list of conditions. (outside of what limited updates are addressed by OTA) To Ford, most of these module updates seem to be a "repair". Maybe that makes sense by Ford's model, because the module update procedure, at...

There a lot of questions through threads on how to jack / lift Mach-E. Maybe some variations are okay, particularly if the load is spread. From the pdf, there is a very specific area between the triangle marks on the plastic strips which is suggested. It is the just under 3" strip inside of...

https://shift.com/ Saw this on another forum for those of you getting close to picking up your MME and possibly selling a car. No affiliation, no experience with them, apparently only CA and TX so far. Reports are of higher offers, pretty common for a new start up.

For those who have not yet ventured into the fuse box, driver's side frunk, here is a quick tour. Below is also the part that stays with the fender. Upper left is the part that makes contact with the fuse panel 12V large flat leaf contact. The red cover is the +12V jump point that routes back...

FordPass seems primarily for reporting data from MME, basic control functions (lock, start, etc.), climate scheduling, etc. I guess you could operate a MME without FordPass? Probably without a smartphone too? But, I find some of the "fixes" confusing. For example, one member @AEtherScythe...
