S2R not turning over

Currently have a non starting s2r, this is what I know so far.

Turn the key and the dials sweep to the right then back to zero.
Fuel pump can be heard. Engine management light (EOBD) stays on.
Immobiliser light does nothing, no flashes, completely lifeless.
So then I have nutural light and oil pressure light on (normal) but also EOBD remains on (not normal).
Headlight is on, all lights indicators working ok but starter switch is not operating the starter.
I thought it may have been moisture in the clocks so I've dried then out in the airing cupboard but no joy.

Could it be the immobiliser aerial? The one that's in the key housing faulty? Is there anyway to check this?

I've tried the spare black key and even the red but no joy.

Any help would be appreciated

Many thanks

If you have a multi meter you could see if you have 12v to the starter solenoid when you press the start button, if not it's probably going to be your starter switch or immobiliser.

Its worth having a 'wiggle' of the cable into the oil pressure switch on the rear cylinder, especially if you've been working on the shock or anything around that area

Has the bike ever started for you or did you get it as a non-runner?
Is the battery healthy (holding a charge and show >13V)?
Does the immobiliser light flash with the ignition off?
Does it flash (fault codes) when you use the red key?

I had an S2R 1000 before the Evo and, if I remember rightly, the motor would still turnover even if the immobiliser antenna wasn't reading the key, it just wouldn't fire. Might it be a fault with the emergency stop switch? I seem to remember, if that was 'off' then the motor wouldn't turn over at all.

Do you still have the code card? That would enable you to start the bike even if the immobiliser isn't working and, if it does start ok using the code, then it probably confirms that the immobiliser circuit is faulty.







Slob's link to Avanti is well worth clicking as there's plenty of useful information there and Avanti are the acknowledged experts on ECUs.

If the yellow EOBD light is on there is an error in the ECU ( a fault detected) you need to hook it up to diagnostic kit either at a dealer or with JPDiag on a PC or similar. This will tell you what the error code (fault) is.

It sounds to me like your fault is probably not the same as the one I had on my 750 but it might be worth a try anyway.
I had an internal break in the wiring loom where it passes around the headstock and flexes as the bars are turned.
A wire in the starter circuit was the culprit and I got nothing when the button was pressed.
However if I waggled the bars from side to side while holding the starter button down, it would turn over and fire.
It was like this for six months or so and always started "with a waggle" every time.
Apparently its a fairly common problem.
My bike is a carby with no ecu or immobiliser and your issue sounds like it may well be different but it wouldn't hurt to try.

Thanks for all the reply's.
The bike was running well since I bought it last year. The immobiliser light is off all the time, no flashes ever. It did used to do something.
Unfortunately I dont have the code to bypass the immobiliser, just the red key.
If I remove the antenna in the immobiliser system it does exactly the same as it's doing now. I've ordered another one but just clutching at straws really.
I understand the kill switch but I feel that my main problem is the EOBD light remaining lit.

This is from the Avanti web page and I've not tried it to confirm but if ECU is the same it should work:-

Darren,

Thanks for the info but I dont think the s2r displays fault codes on the dash. I'll need to get software and diagnostic tools to access the info.

Thanks

[Darren69]

Yea, i just tried it on my '02 S4 and it shows EU and then OFF in the right hand screen and OFF stays on screen. So i dont know what that did? Brexit mode?

[rollo22]

I will say something really simple the kill switch is in run position...

[Darren69]

The kill switch wont throw up Ecu error light afaik. I think that is the issue and I suspect its immobiliser related. Worth checking kill is set to run anyway since tbat has caught me out on more than one occasion.

[slob]

check the ecu is earthed, there should be an earth wire on one of the ecu mounting screws.
also worth checking the aerial hasn’t dropped down in the key housing, if unplugging it makes no difference.

[Darren69]

Its the fact that the immobiliser light is not lit or flashing that worries me as an error with the key read if it was an antenna problem or reading the key would flash to tell you not EODB error. Those clocks are prone to failure and i wonder if it is the imobiliser failing that kills them.
