What is a TSM on a Harley?
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.
How to diagnose a Harley Davidson TSM / TSSM?
I {Heart} Hookers. To diagnose the TSM/TSSM observe the behavior of the turn signals. 2 Turn Ignition key On-Off-On-Off-On-Off-On and then toggle the Left Turn Signal switch twice. – – 3 Turn Ignition key Off-On Verify the Check Engine lamp and Security Lamp illuminate briefly and then turn off.
How to bypass the turn signal module ( TSM )?
This is the key to bypassing the turn signal module. In order to remove the TSM and get the bike to run…you must allow the starter relay to go to ground (which the TSM normally controls). To do this, you would place a jumper between the start relay control (position #9) and the ground wire (position #12).
How does the turn signal work on a Harley Davidson?
Timing for turn signals is picked up by the speed sensor to control the time out distance/time. The speed sensor feeds the speedometer through the TSSM and also the ECM for controlling fuel flow to the injectors. If you need to reset your TSSM security module, refer to Step 5 for instructions.
When does a TSM / TSSM starter relay go bad?
Starter relay could be bad (voltage present on pin 9) (Tn/Gn) when not starting engine. 35= TSM/TSSM bad. bank angle and tamper will not function when this code is set.

Are there any running lights on my TSSM?
None of his signals work, no front no rear. If he plugs in the run-stop module he has running lights on 3 signals. He said he switched bulbs on the one but still no running lite on it. All he really wants to know now is there any way to make sure it is the TSSM. Re: Tssm ? Update Ugh I apologize I did not get all the information correct.
