Yeah, I don't know either. Had 2 fail, both blighted Gen 2 bikes. I think the SA-S and SD-GT. Had to have a fiddle, as you do, finding the same results. Warranty replacements.
I have a 2019 Duke 790 bought in 2021 with 19,000kms, my first KTM after years of Triumphs and Ducatis. So far not impressed with the reliability, oxygen sensor failed this Spring that coast me $800. Tried to start it yesterday and got a large exclamtion sign with 'IMMOBERLIZER FAILURE' notification. Bike did start eventually but I had no confidence going anywhere. I tried starting it today, starts sometimes and the the immob. failure warning comes on, and sometimes it did not start at all. I'm beginning to understand why there are a lot of 790s on the used market. Anyway off to the dealer, hopefully, on Monday.
Immobilizer failure is almost certainly low battery or loose battery connection. The original battery isn't very good quality. I replaced mine with a Motobatt.
@@motorbikewhisperer Thanks for the information, I will suggest that when I go to the dealer tomorrow. Checked the owner's manual and could find nothing on the Immoberlizer Failure. Do you have a model number for the Motobatt battery? Hoping it is the same in Canada then I could potentially oder one from Amazon. Cheers.
Personally I'd be leaving the hi-tech resistor pack in place (with suitable "insulting tape") in place (can you even get orange bodge tape?) and using the odometer like what we used to do when I were a lad, but that's probably just me.
@@motorbikewhisperer : I'm lucky not to have that gene. And unlucky in that one of my outrageous bodges will almost certainly make an appearance at my inquest in the fullness of time.
Having played with my BMW (car) a little, I wonder if it's a code fault? Maybe the software is using the wrong setup? For instance, say yours is a 3 gallon tank, could the electronics think it's got a 2 gallon tank? Probably need a scan tool reader and maybe even re-coding ... maybe a visit to Mr KTM dealer, but I don't even know if you can do that on KTM's. Has it an OBD or Canbus port? ... ;)
I don't think it's that. The sender resistance isn't changing, so either the float isn't floating or there's something else that causes the resistance to stay at the same (low value). New senders are out of stock everywhere at the moment so it's going to be a little while before I can be 100% sure. It does have an OBD2 port yes.

My fried same issue to my ktmadventure790r where did you put the resistor?

Yes good point well made it just triggers my ocd when something that's fitted doesn't work.

Or a variable resistor so you can choose how much fuel you have left.
@@allen_key : Genius!
Kudos for the effort to fix. Very informative. Please switch awm off and lower your slip. Live a little 😂

Did you ever figure out what the stock resistance is supposed to be?
Mine was changed under warranty. Seems a common failure
