Emergency Bike Down Sensor
« on: Feb 05, 2020, 05:42 PM »
I appear to have an intermittent starting failure linked to the EBD, the Engine Management Light gives me a few cheeky winks on starting. I turn it on and off and itíll start, some times itís a 9/10 failure rate, other times a 1/10 failure rate.
I see a few others have had similar problems here and across the tinterweb.

Has anyone managed to come up with a definitive solution? I donít want to start throwing money at new sensors etc if it doesnít cure it and Iíd rather not try and delete it.

Hi Wassy,

I looked after a friends Mk3 2018 650 Versys whilst he was out of the country.

It had an intermittent fault that was a pain to solve, as you described it was a lottery if it fired up 1st time.

The bike was left with Millenium Motorcycles in St Helens, Meresyside (01744 616161).

I explained that there was no hurry in returning the bike, but could they solve the issue - they did.

But, I don't wish to mislead you with the fault they found.
However, it came down to a wiring fault that resulted in the ignition switch being replaced.

I would suggest you give them a call and ask for Gary in the service department.
Gary may be able to recall the exact fault on Mohamed's green 650 Versys, that they had in the shop for a couple of weeks in June last year.

Update:
I didnít phone the garage Vern mentioned but I did get in touch with Bournemouth Kawasaki.

Apparently itís quite common that it contacts to the EBD get damp and corroded which in turn affects the starting up sweep.
Disconnecting the sensor and chucking some contact cleaner (I used ACF50) worked a treat and back to a 100% start rate!

Whereabouts is the sensor? Iíd like to try your fix on my bike.
I'm sorry, really bad reception here, you said your name was Dr. who?

@Siberman
On the Mk3 itís behind the speedometer/tachometer and is accessible by removing the black plastic cowling between the screen and the heads lights. Itíll take 2x plastic pop rivets and 2x 3mm Allan key bolts to remove.

See the photo below for where it is, circled in red 😀

The connector can be pried free with just a small flathead screwdriver

Credit goes to Jkristjan for the photo, I just ďacquiredĒ it from the photo book and added a red ring. 😃

I think my issues start when I removed the cowling to change a headlight bulb and sort some wiring, there was some sporadic drizzle which I reckon got in there.

Oh, okay, if you could send back the credit and Iíll repack it and send it on to jkristjan.😀.
Poxy bike! I have to apply a tiny bit of throttle to get it to start now.

Looking at this and reading other forums, the "signal" seems to be just a logical high of 5 volts and when the bike is tilted, the sensor breaks the circuit and grounds the signal wire. So you can bypass the sensor by connecting leads C and D with a 100k Ohm resistor and call it a VDS bypass. If the fault disappears, you know it is the sensor and you can order a new one.
