TSSM change

When pressing the right turnsignal, the red key-symbol lighted up and none of the right (front nor rear) signals are working. Went to the HD-meq, who said that the TSSM is f-d. When I search ebay for a used one, I find a lot of different P/N:s. For example on my unit(from my VRSCA-06) it says P/N: 68924-00D, and on one from a Dyna-06 on ebay, it says P/N:68923-00D. Is it possible to use or do you have to use the exactly same P/N?

A lot of the differences have to do with the mounting location which in turn sets the lean angle and turn signal cancel angles. They also may indicate the ones with Security and Without. If you find one that would mount in the same or similar location, it may work.

In any case, the TSM or TSSM will have to be Married to the ECU on your bike or your bike will not run (will start for a second or 2 then shut off). The procedure can only be done with a HD Digital Technician or similar device.

There are two types of TSM/TSSM used by HD designated as "Z" or "Y" types. The difference is the orientation of the acceleration sensor and, therefore; how the units must be mounted on the bike. VRSC bikes use both types depending on year. All the early models up through 2005 use the "Z" type and the TSM/TSSM must mount with the long dimension of the module parallel with the bike. Newer VRSC bikes starting with the VRSCR use the "Y" modules and have the TSM/TSSM turned 90°. The 68924-00D you mentioned is a "Z" type module.

Here's a list of some of the TSM/TSSM modules with the type designations included:
68920-01A; TSM-Z 2002
68920-01C; TSM-Z 2005
68920-01D; TSM-Z 2005
68921-01D; TSM-Y 2006
68921-07; TSM-Y 2007
68922-00A; TSSM-Z 2002
68922-00C; TSSM-Z 2005
68923-00D; TSSM-Y 2007
68924-07; HFSM-Z (not used on VRSC bikes)
68925-07; HFSM-Y 2007
69976-08; HFSM-Y 2009
68924-00A; TSSM-Z 2002, HDI (can’t be disables)
68924-00C; TSSM-Z 2005, HDI
68924-00D; TSSM-Z 2006, HDI
68925-00D; TSSM-Y 2006, HDI

These numbers are kits and include the fobs and antenna (if required):
68200-00D; comes with 68922-00A (TSSM-Z)
68207-00D; comes with 68923-00D (TSSM-Y)
68200-07A; comes with 68924-07 (HFSM-Z)
68207-07A; comes with 68925-07 (HFSM-Y)

As to being "married" to the ECU (ECM actually), this isn't quite right. There's a password learning procedure that must be performed so that the ECM will recognize the module. This is easiest to do with the dealer DT (digital Technician) but can also be performed without and is explained in the M1128 Service Bulletin. There's an additional step required with the HFSM and that's the serial number assignment and this does require a trip to the dealer so it's best to have them do both procedures if your installing an HFSM with a buttonless fob.

Not quite true. The marrying procedure can be performed manually using the turn signal switches. Takes 1/2 hour to complete and is documented in the Electrical Diagnostics manual.

Many thanx! Sorry if I sound stupid, but 1; does that mean that I can use any of these modules, as long as it is a "Z" type, to my bike? And 2; where do I find the 3.3 TSM/TSSM Vehicle Delivery?

To avoid having problems with newer features like the neutral/clutch interlock switches it's best to stick to the TSM/TSSM/HFSM for your model year but technically, any can be used if you understand what signals are required at all the pins. You can use either a "Y" or a "Z" type as long it's mounted correctly so that the BAS (bank angle acceleration sensor) doesn't shut down the engine when accelerating or braking.

Section 3.3 is found in the earlier EDMs (electrical diagnostic manuals) and covers routine operations like configuring for sidecar use (changes the sensitivity of the BAS), key fob assignment (procedure required so the fob can communicate with the TSSM), and personal code (PIN) entry (this 5-digit code can be used to arm and unarm the TSSM without a fob). The newer literature has this information in chapter 5 (accessories, horn, lighting and security) of the EDM or at the end of chapter 7 (Electrical) in the service manual.

If you don't have the EDM or service manual for your bike you probably shouldn't be doing things like replacing a TSM/TSSM/HFSM.

Here is the TSSM/HFSM to ECM marrying procedures as of 2007 machines.

Y or Z

Hi again!
My dealar said he could get me a TSM(without alarm) wich I thought was great, but when I picked it up I noticed that it said "Y" after the number. Is this interesting even without the alarmfunktion, for proper funktion of the turnsignalmodul. Will the sensor be a problem?

Regards HD

The list I show in Post #3 includes several TSM part numbers. The function of the BAS is the same in all of these modules so yes, if you use a "Y" type TSM, it needs to be oriented with the long axis perpendicular to the bike or the engine could shut down when accelerating or braking.
