1000ds Cuts Out When Engaging Gears

Is the new side stand switch wired in correctly?

I’d remove the switch, make sure any broken connections in doing so are reconnected and try again.

 

As said, side stand switch not working would be the logical answer. It could be connector but quickest way to bypass is a paperclip or similar carefully inserted in the connector to short the two connections out.

 

Whatever is going on the ECU thinks the stand is down despite the new switch. As Paul says, check the connections to the switch. It should be just plug and play but perhaps the terminals in the loom half of the connector are damaged.
If that is all OK check for 12V on the black/green wire and if that is OK check the continuity of the white/red wire back to the ECU grey connector, pin 38.
And of course it's always possible that the new switch is duff. Chris's suggestion to test with a paper clip should show that.

 

All I can tell you is that the wiring diagram shows a white/red from the side stand loom connector directly to pin 38 of the grey 'body' connector of the ECU. You also mentioned that you measured 'nothing' at the black/green wire. The diagram shows that there should be 12v there with the ignition on.
In my experience wires in the loom are most often broken at the connectors, especially if there has been any movement but it's also worth checking where any cable ties are gripping it really tightly.

 

With the switch connected, can you back probe the wiring to check the two cables, loom side, are being switched? There have been two switches and they switch differently. Switch has three wires, loom side just two. Testing the switch wired up will make sure it’s switching the right ones.

 

I might have given you some duff information!

Although the MTS1000 wiring diagram quite clearly shows 12V on the black/green wire, supplied via a 3A fuse, every other iteration of the sidestand switch with the IAW59M/5AM ECUs shows that wire as being a ground connection. Which fits with my understanding for the ST4s, S4, S4R, 998, 749/999 & 848/1098.
So I 'm reckoning that the diagram from the owner's manual is wrong. Unfortunately that is not an uncommon occurrence from Ducati which can make diagnosis more difficult.
So it might be worth checking continuity between the black/green at the stand connector and ground. Check also the terminals within the connector for corrosion.
The red/white wire will have a floating voltage until the switch is closed and it is grounded. So 10.9V with the switch open or disconnected is probably what you might see.

 

There shouldn't be a grey wire. The wire from the stand switch to the ECU is either white/red or white and it goes to pin 38 of the grey (Body) connector. Below is a pinout for the ST4s but the location is the same and the wire is white.
However I don't think you have a problem with that wire. The fact that you measure a voltage on it with the ignition on would indicate to me that it is connecting to the ECU. I think the problem lies with the switch or the other wire to it.

 

have you tested to see if your clutch switch is working ok just out of interest?

 

The clutch switch won't cut the engine. It only prevents the starter if the bike is in gear unless the lever is pulled.

 

well aware of that, wasn't made clear at what point the engine cut-out so just trying to clarify Derek..

 

Yes. I believe so. Pins 1 and 2 are bridged by the switch to make the circuit, enabling the engine to run. You should get continuity between these pins of the switch when the stand is up. Although the switch has 3 wires there is nothing connected to pin 3 on the loom side.
It's also possible to fit the switch incorrectly, as proved by Ducati Glasgow when I had to take my Scrambler for a recall for the side stand bolt to be replaced. I live 2 hours away and I asked if they would send me the bolt which I could replace and send them back the old one but they insisted that the work had to be done by them. So I had a 2 hour ride to Glasgow in heavy rain, setting off at 7.00am. After a 2 hour wait they said 'that's your bike ready'. I got kitted up and started the bike which immediately cut out when I selected 1st gear. I had to wait another ½ hour while the 'sorted' their feck up, then another 2 hr ride home in the rain.
