-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.
