07 on-board diagnosis?

wondering if there was a sequence of things to do to run a self diagnostic test. i've done it on a 04 r6 and have searched all over for the steps, but came up with nothing.

friend's bike won't start for whatever reason (she rode wednesday night and hasn't since then) so i wanted to run a diag to see what was wrong.

if there are common problems for such thing, please let me know also

edit - all the simple start problems were checked. kill switch, stand down in gear, battery, fuel pump turns on, and it cranks.

turn it on
count the MIL blinks


make sure you go through the simple no start procedures

kill switch off?
in gear?
sidestand?

main thing is do you hear the fuel pump prime when you turn the key

+1^ if you don't hear the fuel pump cycle, possible tip over sensor issue. also, did the Batt. get drained (light's left on)? RShackleford list the first steps/things to check.T.K.

Did she leave the switch off? That would kind of be funny.

all the simple no start procedures were checked.

when the ignition is turned to the on position, will it blink the same pattern until the bike is on? (given the bike can be turned on?)

when i went down on my bike, it started right up. but her bike hasn't gone down. it was just sitting in the garage for 4 days.

Try charging the battery, that sounds like a definite possibility. If not it could be alot of things. When she turns the key to the on position, can she hear the fuel up kicking on.

battery is fully charged. even exchanged batteries with a friends bike.

tried pop starting. nothing.

all the simple check list things have been done. that's why i'm looking for some type of on board diagnostic tool

on the r6 i worked on, they would have a menu of items, from checking each fuel injector for power to resetting tip over sensor. of course, they would only be codes, but the codes were in the repair manual.

i'm pretty sure that with her bike, it's more than the simple starting procedures

S2K on 2,
does the fuel pump cycle? does the bike crank? does the exh. smell of fuel while cranking? T.K.

S2K on 2,

alright, the first step in the manual for "does not start/ hard start" is inspecting the spark plugs........................ yah so, don't recomend that as a first step ( a whole lot of disassembly). stupid question, is there gas in this thing? did you look inside the tank, and not just trust the gauge?

the manual states; crank the engine for more than 10 sec, and check the DTC (blink codes). theres a long and short blink. see what you get (I.E 2 long's followed by 5 short's ='s code 25.) and let us know. T.K.

S2K on 2,

here's the procedure for reading the DTC;

1 turn ignition switch off.
2 remove the seat.
3 remove the dummy connector and short DLC terminals using the special tool.
Connect; the brown - green.
4 make sure the engine stop switch is in the on position.
5 turn the ignition switch on, read, note the MIL blink's and refer to the trouble shooting index.
note; if the ECM has any DTC in it's memory, the MIL will start blinking.

this is the procedure word for word. IF YOU DO NOT UNDERSTAND, OR HAVE ANY DOUBT'S I DO NOT RECOMEND DOING IT YOURSELF! YOU COULD POSSIBLY DAMAGE THE ECM! that was just a disclaimer to cover my a$$. i thinjk you know what your doing from your post's so............do what you will. let us know what you find.

again if your not sure about the procedure, then try and get the fault's from the cranking test. T.K.

I've run into this once before and I'll tell you what it was in my case. Parked bike after ride everything is 100% normal. Go back in a week and it won't start, just cranks and sounds almost like something is very wrong, like a fast crank but it doesn't sound like a compression stroke is occurring.

What I did. Fuel injection allows you to disable fuel delivery by holding the throttle wide open. So I went onto the assumption that for whatever reason this thing is fouled up and I held the throttle wide open and cranked it for 5 seconds at a time. Eventually it started coughing and chugging and came to life (note you don't want to keep the throttle wide open as it starts) She puked out a bunch of black smoke which confirms my suspicion that for whatever reason the thing had loaded up.

This has happened to me one other time at work when an ST1300 was towed in that wouldn't start. Exact same thing.

i'm buying the technique, but what you did to correct the no start reminds me of when rings (piston) lose there seal. we get 2.8L VR6's that love to do that (lose there prime). cust goes in some where, comes out, tries to start car, and bam, no start.

also if you've lost your prime, when you try and start it, you make it worse by washing the cylinder's with fuel. i think Darth might be on to something. i would definitely give this a shot. he's a 100% right about WOT disabeling the fuel system. T.K.

i actually did that to mine when, for no reason, this happened to mine. it just wouldnt start. so being mindful of how i started my carb'd bikes when it was hard to start, i just did the same (just to see what happened), and what do you know - the little bastard started right up.

by the way, she got her bike running somehow. thanks for all your help tk!! and the others also.

S2K ON 2,

glad to hear your problem is solved. that's some weird $hit. i'd definitely say if it does it again, get it down to the dealer (while it's occuring), and let them see if there is an electrical issue before the warranty is up. T.K.

Holding the throttle wide open is the only way to start
a bike that has been sitting for a few days the reason behind
the wide open procedure is to avoid fouling the plugs
if you foul them then the only remedy is to take the plugs off clean
them and start from scratch



If it doesn't challange you it won't change you

Moe,
that makes sense as to why the first step in the service manual under trouble shooting say's to inspect the plugs. i was wondering why they would have you go through so much disassembly right off the bat. for those who don't know, when diag. a problem, you always start with the easiest stuff first. when i read that, i was thinking to my self "your $hit'n me", i didn't know the plug's fouled so easy. learned something new.............T.K.
