-====== ECM Password Learn Procedure ====== ((contributed by Screw Loose Dan))+====== ECM Password Learn Procedure ======
  
-The TSM/TSSM modules share a password with the ECM on fuel injected bikes (and ICM's on early rubber mount bikes).  When replacing an ECM/ICM or TSSM, you must go through a password learn procedure. If the procedure is not followed, the engine will start and run for a few seconds, and then stall.  This will typically throw a P1009 diagnostic code.+The TSM/TSSM/HFSM modules share a password with the ECM/ICM and Speedometer (2004-later) during operation. When replacing an ECM/ICM or TSSM/HFSM or Speedometer, you must go through a password learn procedure. If the procedure is not followed, the engine will start and run for a few seconds, and then stall.  This will typically produce a P1009 or P1010 diagnostic code.
  
-You will typically want to connect your motorcycle up to a charger and pull the headlight fuse before starting these procedures.  The procedure MUST be followed from start to finish without any interruption.  If interrupted, starting over from the beginning is the only option.+The learn procedure MUST be followed from start to finish without any interruption.  If interrupted, starting over from the beginning is the only option.
