Connecting an extra battery is not a wise. There are low cost hand held DSO's available which would be able to look at wheel sensors and crank sensors

so if I get that DSO, I connect each cable of  the DSO coral to each prong of  the end side of the sensor cable and then put the sensor close to the ring of the wheel and make it spin? what should I expect to see in the DSO?
I can test the sensor in my extra wheel set up?

then I can take the rear speed sensor from the bike (that is easy) and repeat test.
an so with the front brake sensor (a little more work to get that one out...)

You would need to test the sensor on the bike with the sensor connected normally and the Coral 112a probe connected to the sensor and earth

The circuitry internal to the ECU is 5v supply to a resistor network with the sensor a small part of it, spinning the wheel changes the voltage across the sensor by a small amount only

Wayne, thanks for your help (again)

The comment  on using the extra wheel is because my bike has only my side stand so can not get the wheels to turn..
That is why I set up the extra wheel and was trying to test the sensors there.

But you mention the sensor needs to connected to the bike? i mean to the IABS module? can not test on the extra wheel?

I also lost you a little when you say the coral connected to one of the pins? do you know which one (pin 1 or Pin 2)
and then the other pin to earth? or is that to the other pin of the sensor or just anything touching earth?

It varies between models whether one side of the sensor is earth or not, I would expect on your model the sensor would be using "balanced" cabling so neither side would be earth. with and Oscilloscope or DSO  I would normally look at the whole component signal with the probe from component to earth, you would need to try each connection to look for signal

Yes you could use the spare wheel but only if the sensor was connected and the ECU active

Re lack of centre stand, that would be frustrating and like my own machines I would be organising a bike lift or paddock stand to work on it

A word of caution re sensors on modern machines, many around the engine ECU's can be 5v operation not 12v so care is needed

yes, I thought of getting me a lift...

I lost you when you say
"Yes you could use the spare wheel but only if the sensor was connected and the ECU active"

That means I need to build a kind of cable bridge between the end plug that comes from IABS module and the end of the speed sensor that connects to plug

a guy in another forum mentioned that because this is a IABS III I could use the below to measure hz when wheel spins

I could try both methods and if they work fine will be a great contribution to all forums.

I placed the order for the coral meter....
will be here mid week....

I could not make the hz meter work with above setup  :(
Coral meter is my last hope  ;D

tested more things

pin 31 of iabs to pin 1 of diagnostic gives 0 Ohms

but 31 to battery -, and pin 1 diagnostic to battery - give both 16.5 in the 20K Ohms selector
That is a lot of resistance....?
Is that ok?

That's best.
Because it is the diagnostic wire without connection to battery

Guys, I am back. I bought the oscilloscope. Where should I connect the black and red alligators to measure signal from sensor?

Can I do it directly without connecting the sensor to the IABS? just turn the wheel, and at the end of the sensor connector plug the osciloscope?

Thanks again for your help!

You have a learning curve in front of you to learn how to use a DSO/CRO, the red lead of the probes is the active and the black is the earth

Use the inbuilt oscillator to learn how to change the display and settings for different signals.  Connect one proble to the LHS and the other to the right then connect red to red black to black and you should see the inbuilt test signal on screen, if not then you change the settings until you see the signal

ok, is like going back to college :)  I did not have these courses...
Thank you so much for your patience....

Ok is this picture representative of what you were telling me?

Yes, now you need to learn to change the time base so you can display different frequencies, ie making for either more or less pulses visible, you will also find you can move the signal up and down on the screen with the arrows you see on each side of the display, as well as the size of the signal displayed. In addition there is a setting to show the amplitude, frequency and other info of the signal on screen as well as record it for transfer to PC via USB

The wheel sensor will be a 0 to 1v signal of differing frequency dependent on how fast the wheel spins so learning the above will be important
