- | 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. |
The learn 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.
