Possible OBC failure

1451 Views 19 Replies 10 Participants Last post by  Adventures on Zero
I have a 2020 ELW that I fear may have a failed OBC. After my last ride for the season a few weeks ago, I parked my bike in my garage and was charging it up to meet the range specified for long term storage in the manual. Around approximately 46% I got a notification that my bike had stopped charging and the breaker had tripped for my garage. I reset the breaker, unplugged the bike but it will no longer charge. When I plug it in, the EVSE starts blue as normal but turns to red in moments. I’ve tried different outlets in my garage, clearing the fault codes, and checking the fuses to no avail. I haven’t yet called the dealer as I have a few months of winter to do that if need be but I’m trying to see if I can avoid a trip there if possible. Anything I’m missing Or possible solutions? I have attached the codes for my bike. The first is before I tried clearing the codes and the second is more recent.

Here are the faults associated with your DTC’s. These are found in the:
“H-D Livewire Model 2020 H-D Electrical Diagnostic Manual” This manual gives testing procedures for the related faults, but most of, but not all testing requires specialized H-D equipment.
Not sure if you already have the code definitions or if this helps but it can’t hurt.
