To make the problem easier to explain I've just made a video showing what the problem is. It's not the side stand switch...

Check my other posts if you want a back story as to why I've changed ECU & Harness.

Ok I just looked at wiring diagram for the 950T, the switch may be good , but it also has a diode in the circuit in the relay unit, if you pop that diode it will show the side stand switch as being open, which would be side stand down, also giving you side stand switch error code

Thanks for the reply bud, I have 2 spare relays and I've tried both, im still getting the error code? Sure both diodes aren't faulty? And the code goes away when I swap out the ECU?

I've attached a screen shot (if it worked) of what I found in the manual. It states 3 probable causes, continuity in the harness, the switch and a faulty ECU.

I dont get how the ECU can be faulty when it's from a running bike?

I am completely at a loss with this 🙈
Could there a way of making the diode seem closed in the wiring before/after going into the relay?

this shows how the side stand supplies an input to the ECU, if everything is good to there , then it is internal in the ECU not receiving the input

I really appreciate the help!

I've just gone into the diagnostics, it states d20 is for the side stand switch. Off meaning the stand is down, on the stand is up. Even with the connection being made manually by connecting two wires, it still says the stand is down (the bike is In neutral and should start with the stand down regardless, am I right?)
I'm getting the correct readings from the relay?

I take it the ecu just isn't receiving the input then? And the fact I swap out to my old ECU and the 19 code is then gone. What a waste of £300 on a ECU that was 🙈

I wish It was, Ivan is the the US & Can market only at the minute, I'm in the UK.

Even if he did do the UK I think postage costs/import charges and the $350 would probably cost the same as just buying another ECU over here.

It's very frustrating!

Umm, that is why you get either someone you trust or a re-mail service. Have them repackage the ECM and ship it as a used part. Value: 50£.

And I wonder if you pay VAT on labor? You have to send Ivan your working, not modified, OEM ECU. He does the equivalent of formatting and hard drive and reloading the operating system (with his changes to the OS included) . So if no VAT on labor, you could prearrange the entire thing with customs. No taxes, and no import fees. Kinda like shipping a carburator to be rebuilt. Only no parts needed. ☺

EDIT: did you read about what changes Ivan does for your bike? If you didn't read the details, you might want to return and read it. And all who have posted reviews have verified his claims.

THE BIKE IS FIXED! Firstly, I would like to thank everyone that has helped on any post I made relating to this issue. You have all been extremely helpful, so thank you!

Here is what I have done to fix the problem (and a bit of extra info) should anyone come across a similar problem, in the future.

Error code 19 means a error in one of 3 things according to the manual:

1: Harness continuity

2: Side stand switch or relay issue

3. Faulty ECU - needs replacing

(4th is ignition connection/barrel problems but this is not listed!)

Having tested all parts of my harness and relay(s) I ended up thinking my ECU was dead, even though I had bought a new ECU from a fully functioning v star 950 (now scrapped) in the states. It was the only thing I could think the problem was.

I have a 2013 UK v star 950 which had a factory fitted immobiliser. I purchased a harness and ECU from America and fitted it to my bike (effectively removing my immobiliser) and here is where the problem began!

My UK ignition and barrel has only one connection; the main ignition connection. However, on the American wiring harness it has 2 ignition connections! SO one random connection had always just been sat in my headlight because I had no idea where it went, it also had 12v going through it so assumed it was for a dipped headlight or something? WRONG!

In the end, fault code 19 is also a fault code when you have a problem with your key and ignition/barrel but this isn't explained or shown anywhere in the manual! I connected that random connection to itself (creating a positive loop) and the code went away! My bike now starts and rides perfectly, like it used to.

So please, don't replace your ECU or wiring harness until you exhaust all other avenues. Check and clean every connection, test them with a multi meter and simply... if a connection is lose and not connected to.anything.... find where it goes and plug it in haha!

Check my video to see what I did to basically created my own connection (to see if it would work) I now have ordered a replacement ignition which has the two correct connections I need so all is working fine again!
