With the laptop hooked up it shows no codes, current or historic. When I check on the odometer it shows 5 codes. U1016 loss of ECM serial data P1502 jiffy stand switch P1001 system relay open/low U1255 serial data missing instruments/tssm B1005 fuel level sending unit high/open The last one I realize is to do with something I did putting the fuel pump assembly back in and needs to be looked at again. I'm 100% confident on my soldering job, however when getting those codes it would randomly show no response, which I guess is telling me there's an intermittent power or ground issue to the ECM. Looks like I have to go through all those wires again !!

OK, you have a connection issue with SEPST. you should see the same as the odometer.


if you can, clear the codes as a start. The jiffy stand will stop the engine and if it is a malfunction not always present you can start bike, it vibrates and shuts off as that switch is saying the stand is down in gear, clutch out.


I cannot remember the routine to reset ecm, something about ignition off/on so many times etc. you will need to search that out.

 

I'm starting to think this thread should be moved to the electrical section as I believe I've got more than one issue, and I don't think it's the ECM.
I cleared the codes, did an ECM and a TSSM reset and still the same problem.
I thought I'd look at the wiring diagrams for some reason, not that I know what I'm looking at! I think I might have stumbled across something, I was looking at the light green/purple wire that runs serial data through the ecm/tssm/speedo etc and thought if I used my DVM to check continuity to ground that would tell me if there's a short in that wire. Is that right? Is that how it works? Anyway I was doing this from the data link and thought I'd check the grey wire too, which runs the the ign fuse and the run/stop switch and I had continuity from that grey wire to the neg battery terminal. Is that telling me there's a short in that wire? I wouldn't have thought that wire should be grounded! Thanks for sticking with me on this, I'm really starting to run out of ideas!!

Also another two new relays, pulled all fuses, contact cleaner throughout and dielectric grease. I thought maybe the grounded wire in the data link could also explain the trouble connecting the tuner?!?

Back to square one! I googled how a kill switch actually works and mine seems fine, it loses the ground when power is applied!!

I've had trouble finding info on the 30 amp circuit breaker. My haynes manual is bloody useless!!
Anyway I think I found it, up between the inner rear guard behind the battery. Can anyone tell me if this is it? If it is, I think it's completely rooted and may be the source of all my troubles.
Thanks, Matt.

That is most definitely the circuit breaker - fingers crossed

Thanks Dave. I got a new one and nothing changed. Still no power to fuel pump fuse. I'm really starting to run out of ideas!

Im not sure if your wiring is the same but this shows the fuel pump fuse being powered from the ignition coil

Sorry off track there the power is from the system relay and piggybacks off the power to the ignition coil

I had to blow the diagram up to see it better
