I previously posted a question about a PCIII making my bike "chirp" when shutting down. Actually it's more complicated than that. Here's the deal.... when I installed the PCIII and started the bike I noticed the rear signal lights flashing together but they stopped and that hasn't happened again.

Now, when I turn the ignition, the system charges and the little "service engine" light in the speedometer comes on... just like it always did. After starting the bike, the trouble light goes out like it always did. This is where it gets wierd.... after about 15 seconds running, the light comes back on in the speedo. It only stays on for abot 15 seconds and then goes out for good. Very strange. I tried disconnecting the PCIII but it still does the same thing.

The bike runs GREAT but I am a little concerned. It is and '06 FLHR with slip-ons, Ness big sucker, PCIII and stock ECM.

Any ideas? Help!!!

 

Have you checked to make sure u didn't bend any pins when the unit was pluged in have seen that on a few bikes.

 

I'm no expert but it sounds to me like you may have thrown an ecm trouble code. If the light goes out and the bike runs normally you may have to just clear the code and should be ok.

 

Would a trouble code only appear at startup or would it remain on?

Also, how can I clear all codes?

Thanks.

 

If it was a one time error it could just occur at start up as a history of trouble that happened at one time . I can't remember off hand exacttly but maybe the owners manual or a service tec could tell you.

 

From what i remember the codes are stored in the radio.

 

That wouldn't be good since I don't have a radio!!!

Seriously, can someone tel me how to clear the dtc codes please?

Check this link, hope this helps.

 

If its a newer bike, you can hold down the trip reset button when you turn on the bike, this is diag mode in the speedo, and you can scroll through the codes by using the trip button, one press moves through the menu, and hold selects, go through them all untill you find a code, and hold it down untill it says cleared. done.

if its older you need a scanalyzer or digital tech, so go to a dealer.

 

Sounds like a historic DTC. If soit'll clear after 50 start cycles.
