Do you know what the S85 error means?

S85 is "Motor Controller -- Encoder fault" and is listed as "Service Required" in the manual...

The good news is that I now know how to find S## error codes in the logs... (half-smiley, half-smirkey)

Do tell!!

Sorry about the fall-over. I hope your ego was all that was hurt.

'D' data line, 1 byte at index 7, convert to decimal.  I've only verified this with my S85 code, and I'm not sure I've seen any other faults.  If someone has a log with another fault in it, I'd be happy to investigate further for other code types.

I've had a lot of S85 errors on my Enertia Plus. It got so bad that the bike would throw them while I was stopped at traffic lights (and forcing me to restart it), and once that error shut my bike down while I was driving in a tunnel with no emergency lane. In the end Brammo took my bike to their HQ in Germany, updated firmware and took the controller and motor out, cleaned contacts and put them in again. That helped. I've not seen those errors since.

Did anyone find out what B9 was for? I just flipped mine on for the first time in about a month to check SOC and it's displaying that code. My bike is going to the dealer tomorrow for the recall and firmware update (hopefully), but I thought I would ask here first.

Has anyone every gotten an explanation for what B9 is?  I got this error for the first time tonight when turning on the bike after work.  It went away after switching the key off then back on.

Just a little bump on this thread because I got the B9 System Fault showing this morning.

Maybe by now someone has found out what the cause of this B9 is?
Thanks

I heared from a dealer that it's got something to do with moisture...
Is it on all the time?

I had the same some time ago:

No it went away while the battery warmed up. It was really cold this morning so they needed some warming up.
So maybe the internal battery heaters made the moisture go away too?

moisture too high. It can go away if you plug at low temp. battery heater will do the job. Check with your dealer to see from wich pack it come & if it's really too high. A reseal of the pack may be needed. 30% moisture is the target.
