Codes galore
2022 - 107 M8 - 8500 miles....
Three weeks ago, on the way home from a ride, I noticed that the check engine light was on. When I got home I pulled quite a few codes.. As below
ECM
- P1100c
- P1511c
- P1600c
- P2100c
- P2105c
BCM
- C0077h
SPDO
- B1210h
- b1217h
ABS
- C1100c
Despite all these codes, the bike ran absolutely fine. After reading them, I started the bike up and shut it off three times. This cleared them all completely. Engine light off.. No codes.
Yesterday, when pulling in to the garage I noticed the engine light on again. I had exactly the same codes set.. The bike was running perfectly. And, like last time, turning the ignition on and off a few times cleared them completely.
I'm still under warranty and I'll be setting up an appointment to get this checked. But I'm just curious.. Has anyone here seen anything similar with their M8?
My concern is how will they fix this if they can't read any codes and the bike is running fine when I drop it off?

I cleared them to see if they'd come back.. As you can see above, I've recorded the codes. If they don't return by the time I take the bike in, I can let the service department know what they were... And actually, I think when whatever caused a code goes away, the system will drop the code after a few ride cycles..

My '21 Limited threw a bunch of codes like that about 10,000 miles ago. Dealer said Harley had a update for the ECM. No codes since.
There's a couple threads about it. I can't search but your codes sound like the ones I had.

Codes ending with :
C are current
H are historical
The ECM codes all deal with EFI
The BCM code is low tire pressure
One of your speedo codes is fuel level sender shorted
Maybe a plug connection that isn't full seated home for your EFI issues
The ABS code relates to the pump switch circuit so dunno about that one.

Can't get in to the dealer until next week. Will update this thread once the mystery is solved

Is your seat one of those low profile custom solo seat or is it OEM?
I also had a bunch of ECM DTC error codes and the fix was return back to my OEM seat.
I believe my low profile custom seat did not have enough clearance under the seat & it was push down & putting a lot of pressure on my seat harness light connectors & as soon as I changed my seat problem went away…hope the helps.

Interesting. I'm using the Harley Tall Boy seat in place of the stock one.. I never had these codes appear while I was running the stock seat.. Will check to see if it is interfering with the wiring. Thanks for the tip..
