Well, this is an odd one. Traction control on 2027 Svart 801 being disabled by Givi Power Hub

[AZCCJ]

So yesterday I decided to install the wiring to hook up my Garmin GPS and Givi power hub for the tank bag. I've done this on every bike I've owned for the last 10 years and never had an issue. I remove the headlight and the panel behind it, giving me access to the 2 set of accessories wires which KTM was smart enough to include in the bikes wire harness. One set is hot all the time, this I use to power the GPS. The other set is only hot when the ignition is powered on, this I've always used to power Givi's power hub in the tank bag. All goes reasonably well, but that headlight mounting design was a pain to deal with. I get it all put back together, take it for a short around the block test drive and everything seems to be working fine.

Then today I take the bike out for a long ride. And right away things go a little wonky. Right when I leave my house I notice I have no traction control, the little TC warning light on the dash stays lit up. I go into the settings and try turning the traction control back on, but the bike won't let me. I then try changing the riding mode to Dynamic but another no-go. I then discover that cruise control doesn't work either. Other than those things the bike runs perfect. As I'm riding along, I'm thinking that I must have pinched some wire under that accursed headlight assembly. So, when I get home a few hours later, I take everything apart again, but I find nothing pinched, disconnected, or cut. I turn the key on several times and each time get the same, Traction Control Disabled message on the screen. Then I pull the connector on the dash and plug it back in. Now all is normal, TC and Dynamic mode work. I put it all back together, go for a test ride around the block and everything seems normal again. I'm now relieved but also a bit perplexed as I never did find out what caused the issue in the first place because I can't duplicate the issue. Which means who knows when it might come back.

A couple of hours later I go into the garage, wanting to turn the bike on to see if the bike is reading miles or km, as I did disconnect the dash from all power. Upon turning the bike on I get the TC disabled warning, and the bike won't go into dynamic mode. I then remove the tank bag power cord and turn the bike on, still no TC. I then remove the seat to get to the battery, turn the ignition on again and now TC works and I'm back in Dynamic mode. I plug the tank bag power cord back in, turn the ignition back on and I still have TC and dynamic mode. I turn the ignition off, then back on again and now TC is disabled as is dynamic mode.

Now I'm on to something here. I can now create and fix the problem at will. But it takes 2 cycles of turning on the ignition in either case. When the bike is working correctly and the tank bag power cord is unplugged, I can turn the ignition on and then off as many times as I like and the bike will work correctly. If I then plug in the tank bag power cord, then turn the ignition on, the bike will still work correctly. But if I then turn the ignition off then back on a second time with the tank bag power cord plugged in, I get the TC disabled message. If I then unplug the tank bag power cord, turn the ignition on, I still get the TC disabled message, but when I turn the ignition off then back on again, everything works again. I was hoping it was just that Givi power hub, but I took the tank bag off my Norden 901, which also has a Givi power hub, and installed that tank bag and got the same results.

Very odd, but at least I now know what's causing the issue with the TC. Still don't know why the Givi power hub is causing the issue.

I don’t know if this is the root cause of the problem, but the Givi Power Hub features a built-in electronic with a power-on delay that monitors the battery voltage when the bike is switched on and started.
The Givi monitoring electronic is designed to protect devices connected to the hub from voltage fluctuations and potential overvoltage when the engine is started; to achieve this, the power supply is briefly interrupted during startup and restored after a delay of several seconds once the engine is running.
For this reason, the Power Hub is designed to be connected directly to the battery and includes its own fuse.
It appears that, in your case, connecting Givi’s own monitoring electronics to one of the circuits monitored by the vehicle’s electrical system (rather than connecting it directly to the battery) interferes with the vehicle’s electronics and causes the malfunction.
