Hi,

I thought I would write down the procedure to be able to reset the battery back to factory specs. If anyone knows a better way feel free to let us know.

Before you start you will need the following:
1. A laptop with a 32 bit operating system
2. A mini VCI cable. I used:

3. An Outlander PHEV :P

1. Download MUT software, the best version I have found is PRE18091-00.

2. Install the software on the computer. (Do the auto run or double click the MUTChecker.exe file). Click Yes.

3. Install the drivers that came with your Mini VCI cable.

4. You will need to purchase the drivers for the software from Nikolay Fedeev (60USD):

5. Turn off UAC. (control panel-search-UAC-slider down)

6. Download Visual Studio C++ 2015 and install

7. On the drivers purchased from Nikolay: Double Click the “Fix MUT-III SE.bat” file.

8. Start MUT3-SE and Left Click the STV Button

Now you are good to go. The Battery Settings are under the Systems list in "BMU"

Very nice instructions ... 80USD and maybe 3h of preparation work on an old PC it might help some "depressed" PHEV batteries

I guess you personally did all these steps ... right ? This is a first hand information, not some copy paste ... right ?

Do you have any further screenshot about the "triple" procedure or battery reset ?

By battery reset what is meant ? Setting back the battery to original 38Ah or else ?

I guess pure battery reset is only few seconds ... not hours like the DBCAM/calibration procedure .. right ?

I have now also made it work with 64bit windows, but you need this driver:
Mini-VCI-Setup.exe

Only reset does not help in any way.
Now your BMU is just thinking, you have a new battery.

Only DBCAM or the complete tripple needs to be done.

Outstanding

Tons of thanks for sharing this.

I just seen from the Andy video that in theory is possible to make a battery reset without any tool ... I will wait it for this and then I might join the club of BMU reset

Not really

Make a BMU reset is still something that might cause some risk, but in general it allows the car to restart the SOH tuning process, which by nature/firmware is pessimistic, so by reset and set SOH back to 100%, it will give many weeks/months with enhanced EV range.

The risk is to potentially over discharge the battery, but ... BMU might have a protection over under voltage even when in use (after 2h rest the SOC is recalculated based on voltage, so over discharge protection kick in, if car get some rest before next EV trip)

So .. it will be interesting to see how low the voltage might go, since changing SOH from 26.5Ah to 38Ah .. is might cause fully discharge the battery .. since 70% of 38Ah is more then the previous SOH.

arnyswart can update us how car behave in long EV usage, and clarify if in this case the SOH was low for real battery degradation or wrong BMU firmware

Please pardon my ignorance but how does his increase the capacity of the battery or is this about some bug that Mitsubishi left in the software for
battery management?
I find the difference in those before and after readings rather questionable and surely Mitsubishi would have addressed such discrepancy by now otherwise it would be time for a class action if they are deliberately derating the battery like that.

Even the cheapest LiPo battery charger will display how many Ah went in and have a discharge feature to show how much REALLY goes out.

Edit: @elm70, I saw your post after I posted.
So can it be confirmed this 'reset' makes use of the 20% reserve capacity?
So lets say 7.6Ah of the original 12Ah are kept as reserve but the true capacity drops from 38Ah to 30Ah with use and age.
I would understand that a reset puts as new 20% figure in the equation based on the actual 30Ah so you have 6Ah reserve.
Before it would have been 22.4 Ah if the total was 30Ah but now you could realistically have 24Ah for EV driving.
What I don't buy is that it shows now 37.9Ah, I smell a scam here!

1 - A "Reset" can not change the programming structure of a system and that is to provide 20% reserve capacity in this case.
2 - Obviously this is not a new car so the overall capacity will be a lot less than 37.9Ah

As far as I know and also from the tech docs of Mitsubishi, after a reset you NEED to tell the BMU the right capacity (especial on the 2019 Model).
So therefore just a reset is not the best option.
