2018 DSR Dead before logs generated
« on: April 28, 2023, 11:42:10 PM »
All was good and then it was not.

I noticed that the rear tail light was on with the key removed and not charging , so I pulled the fuse on the side and parked it up for a few week.
Now I’ve come to look at it and I get a pulsing power image on the dash and if I could the flashing error I get a 2-3 which is CAN error.

However when I turn on the bike on and connect via Bluetooth to download the logs it turns off at about 12%.

Any ideas?

Just a few more points, the contractor does not engage but thats probably an obvious one. I have also done a software (right) button and hardware (left) button on the BMS.
I have had the throttle off and I have checked the socket, I’m going to performa voltage check.

Old school check for air , fuel and spark doesn’t quite cut diagnosing these things  :)

Interesting the dash comes to life when I plug in the 3pin charger.
I have not lost charge ( although I have had a fuse removed) but could the contactor be stuck?

So I turned on the bike with the throttle disconnected and then armed the bike , with side stand up and I don’t get the dash error.
It now stays alive enough to download the logs.

Pre disconnecting the throttle I got this on the first turn on of the day
07745     04/29/2023 12:44:00   Sevcon CAN Link Up   
 07746     04/29/2023 12:44:00   SEVCON CAN EMCY Frame      Error Code: 0x1000, Error Reg: 0x01 Sevcon Error Code: 0x4884, Data: 0x00 0x00 0x00 0xa0 0x02 , Sequence Fault
 07747     04/29/2023 12:44:00   DEBUG: Sevcon Contactor Drive ON.   
 07748     04/29/2023 12:44:00   Module 00                  vmod: 102.115 maxsys: 102.115 minsys: 102.115 diff: 0.000 vcap: 88.125 prechg: 86%

Then after disconnecting the throttle I get this
04/29/2023 12:56:14   Sevcon Turned On   
 07900     04/29/2023 12:56:15   OBD: key cycle pending   
 07901     04/29/2023 12:56:15   Sevcon CAN Link Up   
 07902     04/29/2023 12:56:15   DEBUG: Sevcon Contactor Drive ON.   
 07903     04/29/2023 12:56:15   Module 00                  vmod: 102.107 maxsys: 102.107 minsys: 102.107 diff: 0.000 vcap: 88.187 prechg: 86%

Which I assume is normal from earlier logs.

So I think I need a new throttle.
