Riding to work this morning, I think my 2011 FLHP went into "limp" mode. The 'check engine' light came on, felt like it was running on one cylinder, and seemed like I was starting off in second gear.

I only have 1500 miles on the bike and was able to leave it at the dealership this morning

I have been searching the forum to see if others had encountered something similiar and what the possible causes might be. That's where I learned that there is such a thing as "limp" mode and I am guessing that is what I was in.

Anyway, while doing this research, there were alot of posts about diagnostic codes. I also learned that whatever happened to me this morning will most likely happen again.

These posts aluded to the fact that the procedure needed to display these codes had been described. However, I was unable to find the post.

I hope that someone here will be able to explain the procedure again or point me to the appropriate post.

 

The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes).
Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word “diag” should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted])
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC’s the code will be displayed or the word “none” will appear if there are no DTC’s. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC’s are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC’s again by repeating steps 1 to 9. If the code is current it will reappear.

9 – Press and release the odometer reset button to continue to the next module.

10 – Turn Ignition switch to OFF.

On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.

"No Rsp" (no response) will also appear if the run/off switch is in the off position when doing this procedure.

 

Hopefully the dealer will fix whatever the problem is

In the meantime, I have printed off these instructions and I can at least practice the procedure so next time I won't feel quite so helpless

Thanks alot

 

will these instructions also work on an '02 with FI? Mine has a light stored and the dealer wants 1/2 hr labor just to read it. I have no problems paying a dealer for their experience and knowledge if I can't fix it myself,,,,just don't want to go in not knowing what to expect.

 

Think you will need this one instead. it is for years 00-03 codes

Code check

 

Thank you sir

 

"Background lighting sould illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word “diag” should then appear."

OK, I get that. That works on my 2007 Street Bob amd on my wife's 2005 Low Rider. It does not work on our 2005 Road King. So, what do you do when the things that "should" happen don't happen? Why do I want to know? I have no speedometer, no turn signals, no horn and no brake light and the little red key symbol is lit on the speedometer. To my knowledge, there is no security system (none advertised when we bought it used and it did not come with any fobs). So, if anyone has answer for those issues I would be grateful. Thanks!

 

FWIW....

You tagged your question on the end of a 10 year old thread... many people don't bother to open/view old threads... I just happen to do it by mistake

IMHO.... You would probably get more views, and views specific to your questions, if you started a new thread...

 

Thanks. I'll start a new one.
