Initializing the SE ignition Module on the 2004-Later Sportster

 

When you put an SE ignition module on a 2004 or newer Sportster, you have to perform a specific initialization procedure to get it to work. NRHS customer Jim Young went through this on his Sportster and was kind enough to share the steps and experience with us. Thanks, Jim!

 

Here is the procedure I performed for the "password learn process" on a SE 31759-04.  Since the bike will be in the run position, and not running, for almost an hour, you SHOULD connect the battery to a battery charger.

 

This text is a slightly modified version of the procedure for the TC88 and V-Rod.  Iíve added information to the items that I found confusing, in an attempt to clarify. 

These steps MUST be done EXACTLY as written.  Any deviation will result in an unsuccessful transfer of the password and you will need to start step 1.

 

1.  Set Run switch to the Run position  

 

2.  Turn Ignition key On-Off-On-Off-On-Off-On (this should be done fairly rapidly, no need to wait for the engine light to go off. . . )

 

3.  Toggle the Left Turn Signal Button twice. (This means PRESS THE BUTTON twice, NOT turn the signal ON AND OFF Twice, which would be four presses.)   

 

4.  Turn Ignition key Off-On quickly.  Verify the Check Engine lamp illuminates briefly and then turns off. 

 

5.  Attempt normal start ONE TIME. (This means ONE press of the start button!) Engine starts and stalls immediately. Check to verify that the engine lamp stays on. Password has not been learned.

 

6.  ECM enters Password Learning mode for 10 minutes. DO NOT cycle the ignition or disrupt power for the entire 10 minute cycle.

 

7.  Quickly (within 2 seconds) turn Ignition key OFF-ON.   

 

8.  ECM enters Password Learning mode for 10 minutes. DO NOT cycle the ignition or disrupt power for the entire 10 minute cycle.

 

9.  Quickly (within 2 seconds) turn Ignition key OFF-ON.   

 

10.  ECM enters Password Learning mode for 10 minutes. DO NOT cycle the ignition or disrupt power for the entire 10 minute cycle.

 

11.  Quickly (within 2 seconds) turn Ignition key OFF-ON.  Wait approximately 1 Minute.

 

12.  Turn Ignition switch OFF. Wait at least 15 seconds. Turn Ignition switch ON and start engine to confirm the Password Learn Procedure is successful.  Engine will start and remain running. If engine immediately stalls and fails to restart, the procedure was not successful. Start over at step 1.

 

The other thing that SEEMED to be happening was funny oil pressure light behavior, like not lighting when the ignition is turned on!!! Related? Who knows??? Here is what I do know, after running the above procedure three times, turning on the ignition lit the oil pressure light for the first time in 3 tries and the bike fired instantly.  Iíll assume I did something wrong in the first two attempts.
