Tssm security module resetting procedure. – harley riders usa forums natural heartburn relief

If your Harley key FOB is ever lost, damaged, or stolen, you can easily assign a new key FOB to your Harley. It is also possible to have two FOBs assigned at once. Bob demonstrates the assignment sequence in this video. The process is beyond simple. It is an excellent idea to have an extra FOB assigned for back up, but it is not completely necessary.

The TSSM code consists of five digits. Each digit can be any number from 1 to 9. The personal code must be used to disarm the security system in case the Harley key FOB becomes unavailable. Harley uses the same five digit pin for all TSSM equipped motorcycles. This pin must be changed upon ownership to a personal code. Harley’s initial pin code number is, 3-1-3-1-3.

For example: if the motorcycle is to be parked in an industrial area or near a busy street, it may be best to set the Harley alarm sensitivity to a lower setting to avoid annoying false alarms.


The setting can be changed as many times and as often as desired.

Harley owners should also be aware of Auto-Arming Function and Storage Mode. Auto-Arming causes the system to automatically arm itself (no key FOB present) within 30 seconds after the ignition key is turned off. During this period, the security lamp stays on solid to indicate Auto-Arming is starting up. Motorcycles sold in North America have Auto-Arming disabled by default. However, the feature may be enabled if the owner desires.

For those of you do-it-yourselfers out there (like me) who don’t want to have to make the trip to the dealer every time they want something done, let me relate my experience with removing the TSSM non-pushbutton security system on my ’08 Ultra. This may work for other bikes, but I’m not a factory mechanic – so I can only confirm that this will work on ’07 and later touring. One of the advantages of doing this yourself is that you can keep your original module (along with a printout of this post) and re-install it at any time without another trip to the dealer, or if the bike’s new owner wants a security system.

The factory security system is contained within the Turn Signal Module (TSM), which becomes a Turn Signal Security Module (TSSM) when it is so equipped. If you are disabling the TSSM (do NOT want a security system on your bike) then you have a TSSM installed now, HD p/n 68924-07. This is a roughly cone-shaped device in a black plastic case, mounted vertically under the seat and to the right (starboard) side. Mine was held down with a silver metal clip. The first thing we need to do is replace this item with a NON-security equipped TSM.

So before you go hunting for the TSSM on your bike and removing it, buy the part you’re going to replace it with – in this case, HD p/n 68920-07. They are $114 new from Harley, but I found many on eBay and bought one for $24.95 including shipping to my door. You will also need (highly recommended) a 2 amp (or so) motorcycle battery charger to complete the job safely.

Okay – now, we have everything we need to do the job completely. Find the TSSM under the seat of your bike, remove the clip, and lift it out. There will be TWO connectors plugged in to it; remove both. Note that one of the plugs is larger than the other – this is the input, ECM, and turn signal connector – we will use this again. The smaller plug is the output for pager and siren – tape that one up to protect it and set it aside for now. Plug the larger plug into your new TSM, and slide the assembly back into place, carefully storing the loose connector where it won’t rattle or take too much wear.

Nope. If you try to start your bike at this point, it will rumble and die, and you’ll be cursing me for life. The bike knows that the security system has been compromised, and is trying to protect you, the owner. Getting it to feel all warm and fuzzy about its new body parts takes another half an hour – which kind of discourages the swap-out-and-quick-getaway-routine by a more unscrupulous rider who just happens to be enamored with your new paint job.

In the next step, we’re going to have the bike’s ignition (and lighting) on for more than half an hour, so here’s the part where we plug in a 2 amp battery charger to keep things live. With the battery charger hooked up, perform the following:

5. Wait ten seconds. The Security Light now comes on. The ECM has now entered communication mode with the TSM for the next ten minutes. Look at your watch and do something else for the next ten minutes, but don’t shut off the bike, let the battery die, flip any switches, or unplug anything electrical. Just polish the fenders or something.

6. In ten minutes, the security light will turn off. Within 15 seconds, turn the ignition key Off and back On. This Off-On motion should be crisp, completed in two seconds or less. The Security Light comes back on, and you have another ten minute wait.

8. When the Security Light goes out this time, do the Off-On thing, then when the Security Light comes back on again, shut the ignition OFF. Wait at least 15 seconds, during which time you should be (carefully) unplugging your battery charger (unplug from the wall outlet, then from the bike, right…?).

9. With 15 seconds or more gone by, turn your ignition on, confirm the Run button, confirm neutral, and start your bike. You’ve created a happy marriage between your ECM and the new TSM, and you no longer have to worry about having a key fob or memorizing a security code. Now you can just worry about someone riding off with your bike whilst you’re suckin down a brew in the local pub – use the fork lock!

If you’re like me, you’ll never remember all this two years from now when you’re selling your bike, so print this out, take the battery out of your key fob, and put the fob, TSSM, and this paper in a ziplock bag and store it wherever you would go to look for it two years from now. Happy riding!
