HELP! three warning lights at once, and shut down to idle

[California]

??? ??? ???

Well, I've looked in here for about a half hour and haven't found the answer, soooo,

I was riding, and the engine cut out, not died, but wouldn't respond to the throttle, and when I looked down, the ABS light, the traction control light, and the check engine light were all on. I pulled over and shut the bike off, waited a few seconds and started it up again and the ABS light stayed on, so I decide to ride home and try to figure it out. Within 50 yards of starting out again, the engine shut back to idle only and the traction and check engine lights came on again. So, because I had no throttle, I pulled over again, shut her down, and pulled off the right side cover, checked the fuses, nothing! Tried starting it again, this time all three lights are on, and stay on, but the throttle worked , so I climbed on and rode home. Everything feels normal, except all three lights stay on full time.

WTF?

Yowser!

Sounds to me like you have a loose ground wire or battery connection. Carefully jiggle the wires around and see if there's any that might be pinched under something when they assembled it as well or a connector plug not fully seated.

Unfortunately, it could be anywhere given the symptoms you described. Was there any work done to the bike prior to your adventure?

Recently, 75 miles ago, replace both front and rear tires, will check all sensors, and wires tomorrow.....stay tuned

This sure sounds like the probable cause right there. Great forum for documenting issues. ::003::

Hope it fixes your issue.

Got up early, checked wires, and cleaned both sensors. Then checked ground connections, then every fuse in the ABS system.

All good! that's the good news, and the bad news

SAME PROBLEM! All three warning lights are still on! DAMN

Not that it matters too much, but what year is your bike. Maybe the dealer can run the codes for you to give you a better idea what's going on. Is it still in warranty?

 

[California]

It's a2012, and even the extended warranty has expired! RATS! Talked to the guy at the dealership, and he seemed to know what he was talking about, even brought up the fact that it had gone into limp-home mode, which I hadn't told him. Then when I told him the limp home had happened twice, but now the bike runs fin, he hesitated, said "shit, hmmmm, well, it's still gotta be in the traction control electronics."

As soon as it stops raining, I'm going for another ride to see if another set of connecton checks, and removing, recleaning, and reinstalling all the sensors might make a difference. If not, gonna drop it off at the dealer......

You're sure that front abs cable is in it's loom? Easy to miss. But when mine rubbed through it just turned on the light, didn't put things into an idle. Since the wheels being off was the last thing done, I'm still betting it's something involved with that. I've never had to look, is there a main fuse we can pull to clear codes or do we need to disconnect the battery?
You're sure you didn't fiddle with something else while you had the wheels off? That Check Engine light being on is probably what has put it into a limp in mode. Just reread your post, the throttle problem went away? Gotta find out what that stored code is, limp in mode is pretty serious.

May have missed it, but have the main battery cables been cleaned and tightened? Poor battery connections can cause all kinds of strange problems as can a failing battery.

Sounds like what happened to me when the front wheel sensor lead got chewed through thanks to the carelessness of my independent mechanic. IIRC, the TC will keep you from going over maybe 5 mph. Turn off the TC... it'll run fine.

If you don't know yet: Hold down the TCS button for a couple seconds and the TCS will go from a 1/2 to an "OFF" on the dash.

Final update for everyone... ::012:: ::012:: ::012::

It turned out to be the front wheel ABS sensor wire was in fact sliced, not abraded, so harder to find. It had a nice clean slice through on the inside where I couldn't see it. Then, it took the dealer almost three weeks to get the part at an exorbitant price.

Brought it home this morning, disassembled half the friggin bike to get to the connector at the end of the lead, under the air box! And voila! Perfect again!

Thanks for the help, y'all are the reason I love being a motorcyclist. No matter what your problem, or where you are, you have family members you can rely on!

THANK YOU ::021::

Glad to see that you got to the bottom of it.

When I took delivery of my bike from the dealer brand new I noticed the ABS warning light was lit as I pulled away and rode down the street. Turned right around immediately and took it back. After some BS about needing a few miles to "initiate", a mechanic finally came out and looked at it. He noticed that the ABS sensor had been completely pulled off of the end of the lead, leaving a shredded stub at both the end of the lead and the sensor. Needless to say I refused delivery. The shop pulled a sensor from another Tenere on the floor and had it ready for me the next day. No problems since and in my case only the ABS light was on.

I wondered how the heck that could have happened until I took the front wheel off the first time. I noticed the dealer had not routed the replacement sensor wire through the wire bail properly. Luckily it had not contacted the brake rotor. The second thing I noticed was that the hub plate that carries the sensor has a slot that has to be indexed to a tab on the fork leg to locate it properly. My theory is that when the bike was originally set up (which involves installing the front wheel) the dealer did not properly locate the tab and slot, allowing the hub to rotate and yank the sensor off of the end of its lead.

Mine did this, it was simply careless routing of the front ABS sensor wire after a tire change to where it started to rub through on the rotor and into one of the wires. I cut the cable apart a bit and soldered in some wire to replace the rubbed part and taped it up and haven't had a problem since with it.

I removed the front reflectors to make it easier to clean the fork tubes, but the left bracket holds the ABS wire so you have to tie it down with a zip-tie, otherwise it would........................well you know.

I had a similar problem on my 2016ES. The problem is potentially quite dangerous, because when the TCS engages inappropriately, power is lost which could be disastrous if you were in the middle of passing someone on a two lane road. The dealer diagnosed my problem as a loose ABS sensor on the front wheel. As noted earlier in this thread, turning off the TCS will avoid the random loss of power from inappropriate TCS engagement if you have to ride with a bad sensor until you get to a garage or dealer.

We've had a few of these ABS Sensor wire issues now, mainly due to a spannering error somewhere, but sometimes from road debris. I can see no reason why the wire cannot be spliced & repaired, rather than replaced. surely a bit of soldering/sealant/shrink wrap will keep the weather out? OK. if it was dealer error, fair enough, have the full monty, but a slip of the spanner/routing issue by the owner & a repair would seem perfectly safe to me in most cases.
