B40 fault B8 system fault

[EV promise]

Module firmware update procedure.
I've had a practice this morning and I believe I can explain:- Make sure all the paths to the files are correct.
There are three steps. 1, upgrade 'Comms firmware' , in my case this was 05.01.03 but yours is newer. 2. Then use ' BMP firmware path ' button, this only lights up once the first step is complete. Once this has also loaded ( only a few moments) ,then it prompts you for the final step but says the board must be connected to the cells. Then go for the 'BPM Configuration path' update button to complete the process.
I wasn't able to do the last part as I have no cells connected.Hope this works for you.

So I tried that on the last 2 boards...no luck. I did notice that the last two boards had blown fuse flagged in the fault history. so I took another board that I knew had low soc and hooked it up. It didnt have the blown fuse flag in history and the procedure didnt work on it either. I have 10 boards of the 21 boards that have 99soc. So decided to move on. I have another Brammo battery that I will use as a test bed for the boards after we see if this repair even works. I have the battery module together on the bench this morning and I am trying to heat the heaters to remove the last temp diff fault on the #5 module. Then I will install the module on the bike.

It's certainly a challenge. I am hopeful that once connected to the bike things will sort themselves out but obstacles keep appearing. I count 17 fuses on a board , mostly around the heaters and the bus bar connections.  With the voltages over 16v the SOC is a mystery!

IT IS ALIVE!!!

Test ride 1 mile. need to run down and get some coolant. pics posted of it charging and balancing the cells. no errors yet.

Just watched the video and it's fantastic to see the bike running and hear the excitement. Well done, I'm so pleased.

This is the data log from 1.5 mile ride.
let me know if this works. It is an excel file.

Big congratulations Korbin, you did an amazing job!

Excel from your driving works fine. Great moisture values ​​in the bottom pack!
It messes up module 3 a bit in the upper pack, but still a big improvement.

Ok so the date on those ride files are from the future? 10/22/2022. I can set the clock on the bike. How do you set the date?

Hi, as KaFa says, riding and charging look good. The module heaters came on both times. Went off line 265 when the cells reached 22 centigrade. ( by the way, cells don't charge  at full rate until warmed to 17 centigrade by the heaters ). Now the packs are back together, I think humidity values will settle down as they warm and cool.
It's wonderful to see the repair complete, the B40 error beaten and the bike back on the road. Something to encourage others!

Just did a quick comparison from pics and data log. I did 1.5 miles the other day and about that in the garage today on the stand. so 2 datalogs and pics from the build.

when batteries first reassembled humidity reading were.  module1-48% 2-52 3-61 4-52 5-60 6-58 7-57
Then the reading from the first ride. dry day afternoon not sure
what the humidity was outside.                                      module 1-50% 2-54 3-63 4-54 5-50 6-45 7-47
Then this morning rain 99% humidity outside
garage was 16 C doors closed all night                            module 1-45% 2-50 3-59 4-50 5-45 6-40 7-41
I have only had it on the charger for about an hour the first day and maybe 2-3 minutes today.

another point of possible concern is the pcba temp of module 5. When I put the circuit boards in that was a fail on the software. 6.3 degree split on the temp with max set to 4.0.(Tmax and Tmin on second photo)

now if you see the logs it shows that module 5 pcba temp is at 14C and all the others are at 18ish
Not sure if this will cause a hard fail but may flag.

Hi, the timestamp in the Excel. file starts at 10/20/2022 9:04am.  If you did want to adjust the date I believe the only way is with the Victory Diagnostic software connected to the bike however if you want to adjust it by one day, you could adjust the hour on the clock back several times  before midnight  on the bike to prevent the date rolling over and thus stall it for 24hrs. Might work.
I think the bikes are more tolerant of the module values caused by weather than the factory software where everything is new and at a calibration temperature. The  previous circuit board was badly damaged and not providing vital sensor information for the B40 fault code to occur.
I wouldn't be concerned.
I thought I would share my charging habit:- I only charge the bike to 90 percent after a ride. I  only fully charge it just before a ride, so the heaters have chance to warm the battery, finish the balance and that way you don't see the ' cold battery cutback' message ,  lose some range and  initial regen that way. Take care.

That is an excellent fix for the date. I will try it.
Also good info for the charging. It was a cold day today so I put it on the charger for 30 minutes and then went for a 30 minute ride on the streets. Started at 100% charge and rode 18 miles and ended with 70ish% and a range of 44 miles left. So another success. MTR temp got as high as 134F and the coolant pump started running at 100F and never shut off until I turned the key off.

Hello, good to hear you've had a successful ride. 18mls is a fair distance. The coolant pump start and motor temps are as I would expect so that's great. The  neither file  was  of the first ride sadly, your looking for a file of about 500kb ending in .DRV.  for 18mls. 
Thought I would mention, you  have to select the extension .DRV  in the log file creator or the  Victory Diagnostic program as they only show .CHG files by default. Hope this helps.
