Historic HDC Code
« on: October 11, 2018, 08:25:01 AM »
My 17RGS just started showing a Historic Code U0002: Vehicle Can Perf Error. I took it to the dealer because the engine light came on and the tech just said it was a historic code and it should be fine since for all I know my bike is running good. When I left Harley the engine light was off so I assumed he cleared it but now it has come on again. I haven't done any work around my electrical except for swapping out my stock antenna to a shorty. Would this cause the code?? Should I clear and see if it comes on again? With only 3000 miles on it I'm a bit worried. Thanks.

don't know specifically about Harley's but generally historic codes do NOT signal the check engine light to come on, some great experts here will call bull or back me up on this.  :up:

Historic codes on the newer bikes can trigger an engine light.......after they are cleared the bike must be started and run for them to clear the engine light

:scratch: wow, I guess my car is different, way different, I have some old codes stored in each control module they don't trigger a check engine until they are current again if that makes sense.

Newer cars don't allow code clearing.The light may be off,but the code is not cleared until the ECM decides that the problem has been corrrected.This may take thousands of miles.
This is My fault because I used to clear My code just before entering the inspection station.

   I'am trying out a new scanner and on a Indian it will tell you how many times the bike was on its side. Whats with that, no lite won't let you clear that code. Plus this scanner will tell you a lot info then I've ever seen with a scanner. Next week I'am going to try it out on a new Harley and see what I can find out.
