Where is the best place to get a code reader for these bikes. Do you have to get them from HD? I take it an OBD ll reader won't work?

 

You don't necessarily need to buy a code reader. You can read the codes through the self-diagnostic feature built-in to the bike.

The process is described in the Electrical Diagnostic Manual. I've also seen threads here with the process.

 

Try this:


These apply to 04 and later bikes with the serial bus.

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 should 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" will also appear if the run/off switch is in the off position when doing this procedure.

Also if the code set is a historic code (not a constant light) after 50 start and run cycles of at least 30 seconds each in duration, the light will extinguish itself as long as the error hasn't occurred again.
If it were a current code, the light would remain lit while running.

 

........or you could just buy the code reader for $150.http://www.harley-davidson.com/gma/g...bmLocale=en_US

 

I think both the TTS mastertune and the new Dynojet Power Vision have code reading capability, too. Significantly more expensive than using the self-diagnostic feature, though.

 

Thanks nvsteve, appreciate the info. Just tried it and it worked like a charm and no dtc's. So guess I'm good to go. Mike
