Author Topic: Engine light flashing on brand new V85 (Read 4434 times)

brother dave · « **on:** January 05, 2022, 03:34:18 PM »

I picked up a new V85 Centenario a few weeks ago. During one ride the check engine light started flashing (not on solid, blinking about twice a second). I stop and turn the bike off. Turn it on and light is off. I eventually figured out it happens when the tach hits 5700 rpm. Its at the dealer now but so far they have not been able to track it down. No codes are thrown and there don't seem to be any other symptoms. Just curious if anyone else has seen a similar issue...
Cheers,
Dave

Almost like the ecu has a running in algorithm that throws a code and warning if you go above the owners manual 'running in" procedure.

How does the bike run?

Check the the spark plug caps are tight on plugs. Check if there is any arching across the cap to head.

I had random engine lights on my 20 build, water in the temp sensor was the problem.

My experience with a 2020 was O2 sensor. But, in your case reset the red line to 7000 and see if that changes it.

If it's a V85 TT, is it the "Maintenance" icon (the image of a little wrench), the actual "Service" light or perhaps the "Overspeed Threshold/Gear Shift" indicator light(s)? That third series of lights blinks and can be adjusted for RPM. From the Owner's Manual...

Normally in general OBDII a flashing check engine light is an indication of a random misfire.
I have no idea if that holds for motorcycles though.

I would research more what Phil is suggesting.

SLDMRossi · « **Reply #8 on:** January 06, 2022, 02:50:48 PM »

Yes, as indicated above. The "Overspeed Threshold/Gearshift Light" can be programmed...and might be set for run-in conditions.

Step 1 = determine exactly what light is blinking. There are various indicators on the cluster. Step 2 = if it's the "Overspeed Threshold," determine where it's set.

It's all in the Owner's Manual.

P.S. -- my Owner's Manual says nothing about a "Check Engine" light.

I have a V85 Centenario, and had a check engine light problem. Mine never flashed, but one day it was simply on when I started the bike. Dealer said it may be bad gas, so I ignored it and just kept riding. Seemed to run the same way as before the light came on.

Every time the bike was on, so was the engine light for the next few weeks, even having refilled several times with new gas. One day I stopped for lunch, and when I started the bike again it ran very rough for a few minutes, but then smoothed out and the light went off. No problems since then, and no errors were found at the first service afterward either.

A complete mystery, but since it went away and has not reoccurred I haven't worried about it.

Tis not for us to question why

My 2017 build V7III has thrown up a check engine light intermittently since new, comes on steady, not flashing. It usually happens on a cold or damp day, it will come on about 1/2 km from the driveway but usually disappears later in the day when it warms up before I have a chance to quiz it with Guzzidiag.
I put it down to a cold O2 sensor, i'm probably wrong.

On (very) rare occasions I get red triangle warning on my V85.
It is the engine cutout switch on the clutch lever and it goes away almost immediately. It hasn’t happened for quite a long time now.

Check Engine light is somewhat old school, I think the new term is MIL for malfunction indicator light.

Making too high rpm s in break in period.
Limit probably set to 5500?

I think you are right, the bike is objecting to the punishment, go easy for a few thousand miles then you can raise the rev limit.

I did move the shift warning all the way up but the problem remained. Mechanic at the dealer seems to think it is a software issue. Will post a update when/if they come up with the root cause.

Spoke to the service guys at LaMoto today. They say its good to go. Reason for the issue? Some of the "learning parameters" came from the factory incorrectly initialized. The reset with PADS and now everything should be fine. We will see...

That's why you have a warranty, to catch what factory screwd up.

Picked the bike up today. Issue has been resolved. Just in time for our next snow/ice storm :)
