Trouble code 63?
Historic 63 ECM serial data open/high
Historic 63 TSSM serial data low
Historic 63 TSSM serial data open/high
So this is what i got when I checked for codes on my 2002 heritage classic EFI
I was on my way to work and noticed the check engine light came on and the red key light was intermittent. Also noticed that both lights would go out when i dropped below 10 mph and come back on when i got above 10 mph.
Does this mean I need to replace both these modules or has this happened to anyone before that might know what to do?
Bike runs fine by the way.....help please
