1. Remove right side saddlebag and side cover if so equipped. Remove protective plug from data link connector. Other models will be under the seat.

2. To activate the diagnostic feature,follow these steps.
a. Create diagnostic test wire or use a female spade clip which will bridge the two terminals perfectly.
b. Install diagnostic test wire/clip across Terminals 1 and 2 on the data link connector, they are marked.
c. Turn Ignition/Light Key Switch to IGNITION and wait approximately 10 seconds (4 seconds lamp ON, 6 seconds lamp OFF) for check engine lamp to start flashing.

3. All trouble codes are sent out as a series of flashes. To retrieve the first digit of the trouble code simply observe the number of times the lamp flashes.
a. The lamp will then flash one or more times to indicate the first digit of the trouble code.
b. The length of time the lamp is illuminated and the length of time in which it is off are each about 0.5 second in duration.

4. The second digit follows:
a. Following the transmission of the first digit, there is a 1.2 second pause in which the lamp is off.
b. The lamp will then flash one or more times to indicate the second digit of the trouble code. Count the number of times the lamp flashes to retrieve the second digit.

5. If more than one trouble code is sent:
a. Following transmission of the second digit of the first code, there is a 3 second pause in which the lamp is off.
b. Once all codes have been sent, the data string is repeated. When you have recorded the same trouble code twice, it is an indication that the transmission has been restarted and that all trouble codes have been retrieved.

IMPORTANT NOTE ..If diagnostic test wire is installed across Pins 1 and 2 on connector in lieu of a Scanalyzer, the ECM is placed in a diagnostic test mode and the engine will start. The test wire must be removed from the data connector and the ignition switch turned OFF or the check engine lamp will continue to flash codes. A historic trouble code resides in the memory of the ECM until the code is cleared by use of the Scanalyzer or a total of 50 trips has elapsed. A “trip” consists of a start and run cycle, the run cycle lasting at least 30 seconds. After the 50 trip retention period, the trouble code is automatically erased from memory (that is, assuming no subsequent faults of the same type are detected in that period).

The first number is the ranking number. The numbers after the 'historic' or 'current' is the speedo CEL (check engine lamp) code number (lamp flash count), but without the electrical diagnostics manual you're not going to know what they mean.

See this thread for changes in the 2003 model year readout method on the Check Engine Light (CEL).

Attached are a few pictures to assist you in retrieving codes on the 2003 and older HDs that have the Magnetti-Marelli Fuel Injection ECM diagnostics. 

One picture helps explain the CEL (check engine light) on/off timing as written in the above first post in this thread. The other pictures show the data plug and the HD jumper wire which has it own P/N but can easily be made by yourself.

Here is some additional information on reading the DTC errors on the speedometer with the CEL (Check Engine Light) for Harleys with the Magnetti-Marelli Fuel Injection ECM diagnostics.

Attached are two extracts from a 2003 manual that shows the two digit codes that are seen by the blinking CEL and the method of reading the code with the blinking CEL (Check Engine Light).

This was covered above but you can never have too much information.

Hello folks, I am new to this forum so please feel  free to let me know if I violate protocol.
I tried to download the event codes using the procedures in this thred with no success. After installing a shunt  across pins 1 & 2, I turned the ignition on and the check engine I dicator illuminated for 4 or 5 seconds, then it extinguished  and never came on again.   Any thoughts on what I may be doing wrong?

I don't own a bike like yours with the flashing CEL (check engine lamp) method of diagnostics so let me try to help the best I can (my 2008 bike does DTC readout via the odometer).

One of the notes I read in a the 2003 model year documentation is...

Quote
If trouble codes do not exist, then the check engine lamp (CEL) will not flash even though the jumper wire is properly connected within the eight second period.

Also the 2003 documentation states that you should place the Engine Stop/Run Switch in the Run position. I don't see that being said in the above information.

Do you have a CEL illuminating at normal start up and staying on?

Another thing to determine is that you have the Data Plug and not the accessory plug. Your Road King might have a front fork switch that is a toggle switch for after market accessories to plug into that plug which I believe is also under the seat.

If you're using any fuel modules like me, Power Comander , you need to remove it and plug the harness back into your ECM

Good info! I didn't know that. It makes sense.

Does this apply to 2004 and newer motorcycles? Or just the 2003 and older H-Ds?

Since I have successfully read codes on my 2008 in the past with my Vance & Hines FuelPak installed without an issue I would say it isn't an issue on the 2004 and newer Harleys but I think what dcny55 has shared could be an issue on almost any year. Plugging something inline with the ECM can certainly present an unexpected result. If ever you have problems reading DTCs or have issues with any year HD it might be wise to unplug any aftermarket fuel controller/computer and try things again.
