MTC Failure What Do You Think?

Post by furndog » Wed May 03, 2017 7:19 pm

Like others I got got the dreaded MTC Failure on my last ride. It's a 2016 with 900+ miles. Yup went into limp mode would only rev to about 6000. I toggled through the matrix display and sure enough my Settings screen has been replaced by the Warning screen with MTC failure number one on the list. So I limped into good spot for lunch and called my dealer, they said bring it in if you can. So an hour or so later I saddle up and head to the dealer. What the..... bike fires right up, no warning, revs to red line all is good right? Well maybe not, my Setting screen is still MIA and the Warning screen is gone now but that's a good thing. On the way I run low on fuel and get that warning on the screen and the MTC warning is not on the list this time. I fuel up and head the remaining few miles and toggle through the display to now see the Settings screen has reappeared. The dealer hooks it up to their diagnostic tool as soon as I roll in and find four codes. MTC exhaust valve, turn signals, heated seat, and something to do with Can bus. They clear the codes and send my on my way saying let us know how that works. Great I'm thinking doesn't anything need to be fixed like maybe a new exhaust servo or a turn signal control module or whatever makes those things work. So I guess I'll just have to go put some miles on it and wait to see if it happens again doesn't inspire much confidence. So what do you guys think?
Good luck, have fun, and don't break anything

Exhaust valve sticking. Causes problems for other manufacturers too.

In the exhaust Steve, if for any reason the valve doesn't open and close freely with restriction it will throw a code. they have been replacing the actuators that pull and push the cables when a code is thrown up, but i also suspect the problem may be a tight valve, or bad cable movement.

Kind of what I was thinking they don't usually throw a code for no reason at all. We'll see what happens after I rack up some more miles.

Okay so were talking about the cable actuated valve just before the slip on ? That's what I was wondering

^^ Yes.

For what its worth I try to keep that area clean, also spray it with wd40 or similar frequently. Dont know if the lube does much but it might help wash out dirt before it gets cooked off!

^^ and you can probably give it a much better clean on the inside as well by removing the end can. Easy enough.

My exhaust valve and cables have been removed, and after 6000Ks no fault codes, I'm thinking the the actuator gets an easier time not having to push and pull that exhaust valve.

I got a 'momentary' MTC warning after I changed the oil recently - it appeared after I started the motor to suck in the first 3 ltrs before adding the final half ltr....then disappeared on second start with the full 3.5 ltr oil change as per the manual.......bike fine, oil level correct, no warning on dash (only the momentary one) - I was using the kill switch to help pump some oil into the new filter element....maybe there's a better way to disable the injectors for a minute to fill that paper element with oil before allowing the fire to start... :?: .

GT Probably threw the MTC warning up as a general alert because there was no oil in the motor until the pumps sucked some from the dry sump reservoir and covered the sensor......

Anyway, I've seen an MTC warning, but had no problem with it......high tech whizbangery...things to learn... :roll:

Sorry no help for your experience.....but don't feel un-confident.....ride it with vigour....might just have been a brain fart.....or a bit of grit on an ABS sensor............let us know how you go.. ;)

Like the dealer said go ride it and see what happens which I have now some 200 miles later no warning. It's beginning to renew my confidence. I've had quite a few KTM's and this is my fifth big bike, two adventures an SE and an SMT so I know they can be a bit quirky at times. That said this just started the other day a slight exhaust backfire when up shifting not every shift with or without quick shift doesn't seem to matter. Anyone?

^^ its probably the SAS system letting air into the exhaust system to help burn unburnt fuel, if you remove the CAT, its much worse, you will get a flash flame at night. on the 2014 1290R, the mapping for the open exhaust would really back fire, so the SAS system had to be disabled or removed. on my 1290GT I've removed the full SAS system and fitted little plugs to fool the bike its still operational, i do get a tiny crackle, but barely noticeable.

after every oil change i run the bike 600 secs without interfering and then shut it up , let it cool down and check the level by then your oil filter should be ok.
no need to worry about the oil filter working or not in the first start up as the oil is new its ok .

oil choice is important then that.

Cheers furndogie, my GT has a backfire when I'm shifting up 1st to second (sometimes). I think it's down to me competing with the QS because I'm so used to using the clutch......it doesn't worry me (actually it sounds quite tough) and when I either do the clutch thing - or - the QS, not both together, it doesn't fart mid shift..... :lol:

Well here we go again I got the familiar MTC Failure warning yesterday. This after only 600 miles since they last cleared the fault and sent me on my way. This event was a bit different than last time. The bike totally went dead like the key got turned or the kill switch pressed, the instrument cluster flashed then the MTC warning appeared. Slowing down rather quickly and with cars right on my ass I pulled in the clutch and hit the start button..........nothing! Oh shit! No where to pull over either. Still coasting and cars stacking up behind me I think I can jump off an push it to a turn out just ahead but I hit the button and give it another try, whew it starts this time boy that was scary. So I swing through the pull out turn around and right back to the dealer. Yup you guessed it the exhaust valve again. They clear the codes and send me on my way again only this time we book an appointment so they "can have a look". That's supposed to happen Friday we'll keep you posted.

Furndog: I think its potentially dangerous to ride the bike with persistent MTC failure warnings for the very reason that you just experienced. The bike can suddenly shut down all power and if that happens in an inopportune pace, it could land you in trouble.

Mine did exactly the same as yours until it failed completely and the bike went into what my dealer calls "limp mode" in which case it runs OK and is rideable but at much reduced power. On my bike the MTC warning turned out to be caused by an exhaust valve servo motor failure. The good thing is that when the servo motor was replaced and the CPU's reset, the quick shifter and cruise control failures also disappeared.

I totally agree Allan it doesn't take long to think up at least a dozen worst case scenarios. They will have to come up with a fix this time.

G'day all, only idea I can suggest is to ask your tech's if the servo/ex-valve can be 'eliminated' using a plug-in module. Might cost a bit but it would remove the 'trouble maker' so you can forget about possible future failures.

Anybody done this on a 1290 :?: (sorry I haven't been researching any other posts on the forum - I've not had to go looking - my new sweetheart runs very nicely :D .......I know,.. smug bastard,.. touch wood eh!.. :lol:)

I'm heading upwards to 7k now whilst in Spain and mine also has been faultless, with hearing these issues I've resulted into talking to mine calmly everyday and give it a little pat .

The GT really rocks, it gets better and better with the miles.
