she won't start

 Do you have a meter ? If so, checked the battery with the ignition off then on, there should only be a couple of volts different.

If the voltage drops to much the ECU might be stopping you from starting the bike .

Triumph have this trickery also .

just had a look at mine 16 plate it does the same when kill switch is on blow the kill switch out with compressed air make sure there is no water in it. try another kill switch if you can

no no codes just keeps reading check nothing else.

Do these models still have the clutch switch? they were always a source of frustration before? 2 wires going to a switch behind the clutch switch gear...

[porter]

Yes its still there. Worth a look, and the side stand switch also, I just jumped them with a bit or wire the time I had the no starting issue, wasn't them.

The workshop manual says CHEC is displayed when the instrument panel doesn't receive a signal from the ECM for more than 5 seconds. There is no fault code associated with this. It suggests kill switch, sidestand switch, ignition fuse or the wiring connecting them. You get an "FI" 3 seconds after turning the ignition on.

After Megashorts above below I had a search through the forum for a similar problem......... a CHEC can only be caused by the side stand switch, the kill switch OR the ignition fuse OR the ECM signal not getting to the display because the system voltage is low,
see post #5 here.......https://www.v-strom.co.uk/smf/index.php?topic=21973.msg208083#msg208083
and post #8 here.........https://www.v-strom.co.uk/smf/index.php?topic=30462.msg301358#msg301358

both posts from greywolf (RIP) a man who knew his way around a V-Strom.

Because you have CHEC showing, normally the 'bike wouldn't turn over but if the above was the problem then it would turn over but not enough voltage to the ignition system.

I still think it's a voltage problem, either the battery itself or a wiring/corrosion problem in the ignition circuit.   
That's if I'm reading it all correctly.

Edit...also mentioned by kwackboy above.

   Mick. It's amazing how many weird effects a duff battery can cause. Test it under load

[sjrainsford]

To rule it all out, personally I'd short out the side stand switch, kill switch etc too. See if you can do the lot together.  You'll know if you get it right as the fuel pump will run its prime cycle.
If you don't get the prime cycle, it won't start anyway as the fuel pump isn't going to run with CHEC on the screen.
So ignore starting it, you need to get it to the point where you get the fuel pump prime cycle.  That should happen as soon as the safety circuit is completed.  The prime cycle will happen generally speaking even with quite a low battery.  That's always a good sign of a low battery as the pump will sound wrong.

no can't get any codes. changed battery too checked fuses still nothing

Just a thought, maybe your bike missed the earth lead recall. Connect a jumper cable, if you have one to the negative battery terminal and other end onto the frame somewhere, tank support a good place. This is what I did when mine went dead a few years ago.

[Megashorts]

The sidestand switch doesn't carry the power to the ECM, it goes through a relay. If the relay is faulty bridging the switch isn't going to make it work. Can you tell if there is power at the ignition fuse? It goes from there through the sidestand relay, through the kill switch and then to the ECM.
