System Fault B40 Error Bike Does not Run

[HadesOmega]

I know there's another thread about the B40 fault but it's burried in the archives so I started a new one for my case.  Sooo the day has finally come Empulse139 is dead in the water.  I made a VLOG about it but here's my story.  I rode the bike the previous day and the bike ran great as usual no problems.  I ran it down to about 26% SOC and then like I usually do I plugged into my Level 2 charger at midnight.  I remember I came to check on the bike before I went to sleep and it was at about 76%, I was going to disconnect it if it was around 90% but it wasn't so I just left it charging the whole night. 

The next day I hop on to do some door dash and try to fire the bike up.  The bike turns on but I get no throttle response and I'm getting a System Faul B40 error.  Before I was getting a constant B9 error but I could at least ride it.  Now the bike is just dead not going anywhere.  All the 12V electronics works so the pack has power and DC-DC converter works but the bike will not move and it will not charge also.  I plugged the charge cable in and the screen turns on and nothing happens.  Every once in a while the headlight will flash and the green LEDs flat with it. 

Annd that's where I'm at.  I think it's time to call up Polaris, I haven't been able to find any place that will work on this bike unfortunately.  Still 1 year left on the battery warranty so time to really get back on it.  Such a shame I've really come to love riding this bike it died on me just shy of 8000 miles.  Does anyone know of anywhere that still services these at least in California?

I looked up the B40 fault and it has something about the BMS being in idle mode.  I'm thinking something caused the BMS to not function or sleep.  Don't know how to wake it up.

Any idea what B40 means?

[HadesOmega]

According to the manual and service manual it is
Code B40 | Service Required B40 | System Fault B40 | BMS Back in Idle Mode

I'm guessing it is something wrong with the BMS.  Previously I had the B9 error also.  So something is up with the battery system.

I'll see if I can download the log files, something must've happened to it while it was charging.

That's bad luck 
Try ask someone who already had this error code (MichaelJ or JeffK)

I wish you would solve the problem as soon as possible.

Yeah from what I have seen is it goes either one of two ways.  You turn the bike off and turn it back on and it runs like it's suppose to.  Or the B40 stays there and the battery has to be replaced =(

Here is a description of the B40 error from the Brammo Enertia repair manual:
"This is a necessary safety feature, however, since this is a latching fault (does not clear until power cycle), care was taken to make it filter glitches and only happen when absolute necessary."

Try the following:
1) disconnect the main battery contact in the front of the motorcycle, leave it disconnected for a while and then reconnect it, try to turn on the motorcycle to see if the error has disappeared
2) try to disconnect the main BMC connector on the top of the motorcycle for a while, then plug it in and try to check if the error has disappeared
3) try to disconnect the two main VCU connectors on the top of the motorcycle for a while, then plug it in and try to check if the error has disappeared

If that doesn't help, contact Polaris to tell you how to fix B40 error. It would be ideal to get a repair manual for Victory / Brammo Empulse.

What firmware version do you have? Is it the latest? Some Brammo Enertia / Empulse error messages have been fixed by uploading new firmware.

Thanks I will try those things.  I was going to try to download the logfiles but I got tied up with another project.  Hopefully can get bike started, but I think ultimately before my battery warranty is up I need to search for a service center...

On the start up screen it says it is
Version 02.11

I did email explaining what the problem was to Polaris and they sent me to a Victory website that had a dealer locator on it.  So I guess I will try calling up all the dealers around me 2 of which I've already contacted and see if they will service the Empulse. 

Here is some of what the email says:

I copied the log files onto my computer but I can't get the Victory Diagnostic software to work on my computer, I even tried it on another one computer and it crashes whenever I start it up.  =(  Is there any other program I can download to view the log files?

[Leander]

Sent them to me, if the are the same as the brammo version I can convert them to excel.

[HadesOmega]

Hmm ok I'll attach some to this post I'm not sure which one to put because I've tried to run the bike a bunch of times since it died on me.  I think the date is off by a day.  I'll post 2 days worth of logs. 

This is half of one days...  derp it only let's me post 500kb total I guess this gonna take some work O_o'

[HadesOmega]

This is the 2nd half of the first days log

[HadesOmega]

And the 2nd days the're much smaller and there is one more from the next day

[HadesOmega]

So it should have stopped functioning somewhere around those files here is the latest one

If I remember correctly, for successful analysis of data from the flash drive it is necessary that this data is complete and in the original format (no partitioning or partial zip archives)

BTW: have you tried disconnecting the main battery connector? Maybe it will save you a lot of time
