I went into my garage and I noticed that my 2015 SR was showing 00 SOC when plugged into the onboard charger.

I turned on the Error display on the dash and I get the following according to the Unofficial Manual:

6 BMS Throttle Enable Wire Error - throttle
40 BMS Throttle En Wire Disable - Throttle
48 SEVCON Startup Disable - Controller
49 Contactor Open Disable- Contactor
25 Contactor Open Warning - Contactor
30 BMS CAN Error - BMS
57 Module Did Not Connect - BMS


Yikes! Any ideas?

Sounds like a battery controller failure.

Is that on the mainboard or on the battery?

Hello, I had it happen few times on my 2018 FXS, with similar but not the exact errors you have, I had the 47., not the 57.
I think the culprit is error 30: BMS CAN error that (at list on my FXS) lead to BMS going to hibernate status and not leaving it until CAN communication come back to life, during the communication errors all temperatures reading are not working.
In my case after few hours or a night, the bike exit hibernate state and powerup as nothing happened.

Have you tried hitting your bike with a hammer? That usually works for me.

I've had that a few times already

After pulling the two cables on the Main Bike Board (MBB) 10 minutes all worked well again.
Pulled the logs, the MMB was set to 01-01-1970 (later on the date was set automatically to today).
Maybe you can try the same?

I did cuss at it, but I will try the hammer.

The whole battery was replaced a couple months ago by warranty.  That includes the BMS right.

If I had to guess, I think it is the Sevcon Controller.  Zero said that the Sevcon was slow to sync -or something like that- they recomended to replace it, but there were no errors, so I did not want to spend on a controller that was working, but slow.  I did not notice anything wrong.  The bike was fast enough to boot up when the key was switched.

Well apparently towing the motorcycle to the dealer is enough to scare away the gremlins and get the bike running again.

The tech said that it was running and charging fine when they booted it up.    OK

The notes from the service is that perhaps it was the BMS and if it happed again they might replace it ( the BMS was replaced under warranty in March with the whole battery).

They tried to update the firmware, but there was a update glitch, so Zero had to do it over the phone for them.  Rode it home with no problem.  Glad to have her back. Hopefully the gremlins stay out for a while.

Those gremlins might be unseating a critical connector when no one’s looking. Hopefully it’s all over, but it might be an issue like that if it reoccurs.
