No start after accident

[LenJ]

After any ideas from the hive mind please....

First a little background, "stepped" off the bike at around 30-40 mph in some roadworks on the motorway due to debris in the road. Little obvious damage due to the tralex crash bars other than left indicator broken, screen and mechanism taken a knock + scuff to panniers etc.

Got back on the bike, turned the ignition on, dash lights up, but the starter won't operate.

Ended up getting the bike recovered to a local triumph dealer who due to pressure of work could only have a couple of hours on it. They checked the clutch and sidestand cut out switches + the fall detection switch and worryingly found that the triumph diagnostics wouldn't communicate with the bike.

Had the bike recovered home and removed the plastics, but can't find any obvious damage to any wiring so I'm wondering whether the knock on the front has damaged the clocks or ecu ?

Also found that tigertool can not communicate with the bike either and just comes up with "ecu read error"

Hopefully should be a pic of the dash.

Any ideas gratefully received......

Sounds like something came loose during the drop.

If there's no comms to the ECU I'd check the connectors on there first. Maybe not all of the pins on the connectors are making full contact. Also check all other accessible connectors.

Also check the pins on the diagnostic connector to make sure none of those are loose as that can cause comms issues.

I had a car some years back that just died on me one morning but some of its functions worked. Simple problem with the ECU connectors not being fully latched in.

Maybe a daft question, but ......

Have you checked the Handlebar "KILL" switch
to check it hasn't been knocked, and is in the RUN position ?     

Cheers

Good point well presented coconut, but yes

Proving a bit of a tease, checked connections to ecu etc, all looking good.

Slight concern at the moment being the clocks have had a good knock asone of the mounting lugs at the top is broken, don'tknow whether damage to the clocks immobilises the bike?

Will have a look at the ignition switch next I think as it seems a bit immobilisor ish in that the gear indicator only displays a dash no numbers, temp and fuel both zero and the trip only displays dashes as well?

The final tease is the bike will not display the fault codes when doing the button press whilst turning the ignition so can't even get any fault codes

It was worth a try !

You've checked the two multi connectors at the main ECU,
and presumably the two multi connectors at the rear of each side of the Instruments pack.

The wiring from the base of the Ignition switch runs across to underneath the left loudspeaker,
where there is a multi connector plugged into the Trophy harness.
The multi connector should be attached to a clip underneath the Immobiliser ECU.

If that checks out, the next stage may be the daunting task of checking continuity of individual wires for a break

Hi again,

No idea of how to go about changing milometer figures if you needed to replace the Instrument pack,
or whether the recorded miles are stored in the Speedo or the ECU, but if needed - I just checked eBay and :

Triumph Trophy 1200 SE 2014 speedo instrument clocks 2013 - 2018 at £169.99

Listing says in "Good condition".  ( I have no connection whatsoever with the seller )

Cheers,

[LenJ]

Thanks Coconut. Looks like someone has been in to the ignition switch before as I can see the black sheathing has been cut....  I'll keep you updated when I fight my way in.

No idea if this will help, but you may remove the seat and find the starter relay and jump the terminals on it with the key on to see if it will turn over.  You can go through the whole start from cold without touching the throttle during the entire test, let it idle until the cooling fans come on and let it idle another 12 minutes minimum before shutting off and see if it makes any difference at all.  I'm not the expert here, but I'd try the easiest thing to get to before I started trying to strip it down.
