I ride a 2001 FLHTCUI and just now replaced the original defective TSSM with a new one. I was all set to follow the procedure to "marry" the new TSSM to the ECM, but the bike started OK and kept running. I had to reset the keyfobs, but that was all. All alarm functions work fine. Does anyone know if just changing TSSMs doesn't require the learn procedure? Maybe it's needed only if changing from a TSM. Just curious.
