Hello all and thanks for allowing me to be here I have a 2005 CVO Electra glide driving it the other night I pulled off to the side of the road to talk to a buddy and it would not start it has started a couple times since then but now nothing fuel pump is good everything works I go to the systems relay and if I ground the negative side of the coil on the system's relay which goes directly to the ECM number 4 input I believe it's green with orange Stipe everything turns on and it's starts otherwise I get no fuel no ignition and only starter turns over. I have checked the grounds at least all the visible grounds pulled ECM and went through it change the relay even though I bypass the relay and it works messed with the security system it engages and alarms and turns back off when I turn it off.... any suggestions would help. Thanks again in advance. I would suggest it is the ECM but when I bypass that one ground off of that systems relay groundside coil it runs fine
did you end up finding a fix???

unfortunately no, thats a 5v circuit that sends data.. sometimes shows slight pulsing on a multimeter which would be safe to assume is indicating that data being sent, but no way to actual know what that data is unless you have a diag reader specifically to read and access TSSM throughput.. hence harley davidson dealer or DIAG4BIKE which is what i currently own
it is my understanding based on visual data shown in the software that the TSSM only sends data, doesnt receive, its "trigger alarm" sgnal is triggered by an actual 12v command from the bikes wiring, i.e. "ignition on while armed" would be the only trigger alrm signal input to the TSSM .. the TSSM has the shock and tilt sensor in it
this is why the TSSM can be disabled while still connected, but no more alarm system
which by the way you might still have the option to do if its still getting power and ALL lights work, once the TS and hazards stop thats it.. the TSSM cant be accessed anymore
i can email you a wiring diagram so you can further trace wiring to be sure.. in my case i was pretty set that the tssm needed replacing.. after that i just toyed with the system to learn my way around it

I did not ...I'm guessing I will have to take it to the dealer and it's gonna be the ecm or the tssm but both need to be programmed to the bike ...I would just put a thundermax on it but I don't want to hack into a cvo bike like that.

heres the thing with the TSSM and ECM, the tssm does NOT need to be programmed to the ECM, it needs to be programmed to the bike, ANY bike, for it to start communicating with the ECM and provide us with these extra special moments that destroy our brain cells.. lol.. the fact that the VIN is in the tssm, is irrelevant, ive swapped known working tssm units into my bike and they all worked when i was diagnosing my issues last year.. all with diff VINS and from diff year bikes
the usual thing to do, IF YOURE HEADED TOWARDS A TTS, take it to the dealer for TSSM deactivation if its not completely fried and then install a TTS, if it is completely gone and the dealer cant get into it, just install a TSM, NOT TSSM with smart siren, the regular turn signal module.. and youll never have the problem again, the regular TSM is seperated from the ECM, and in this case, seperate from the TTS
either way, the tssm does not communicate with the tmax, atleast its been that way last time i installed a TTS, no option for intergration of OEM alarm system, it was still there and wailed when voilated, BUT, the bike still started and became an STREET GLIDE ambulance as it rode away
truth is.. you can actually do all this at home without going to the stealer, buy a regular TSM on ebay, readily available, and then the TTS.. and youre all set, BUT NO MORE ALARM SYSTEM
btw Jim, ive emailed you the diagram

hey ghost, you said you can disable TSSM while it is still connected? have you done this, i thought that can only be achieved if you swap out the module for a TSM module? i too am having the same problem, im not getting the ground from the ecm to the system relay, i can bypass it and the bike starts, however fuel pump will continue to prime and i get the engine light
hey Kernwroght...
the TSSM has to be connected to be disabled, its access is thru the data pin (#5) from the ECM, via software and has no direct link to the PC , BUT the ECM doesnt send any info.. only provides a thruput for programming/activation/deactivation.. and i use the term rogramming loosely here, as mentioned before in a post to Jim.. programming heresay is mostly for FOB assignment and BS like that..

Don't know where you are in the process, last summer I had a dying issue I blamed on the ecm. The ecm is married to the tssm, just as the fob is.
for $100 I bought a used threesome that made it plug and play. Guy didn't want to send the fob, but I insisted incase the alarm was set.
for the money you're looking at to take a guess you might want to consider buying used.

Wiring diagram
do you have a wiring diagram?
if not, PM me an email address
Y/G is power from system relay,
Y/B neg pulses fron ecu rear coil
B/O neg pulse from ecu front coil
G/B is the ION sense return to ecu..
heres my take on this from exp..
the serial data wire , #5 on ECU, GREEN/PURPLE from the TSSM sends an OK command (no alarm condition) to the ECU allowing the #4 wire system relay power up, FUEL and IGN, since the TSSM sees a fault it wont allow the bike to start, jumping the system relay bypasses pretty much all electronics and will trigger a xmas tree of MILS

if you figure it out let me know I still have not got it fixed would love to get it fixed without going to a dealer. I will look for the diagram I had it somewhere also
