Hello all
So my r6 started acting up. The speedometer lights up fine and all the functions work clock,rpm, tcs etc
Only the odometer and the speed isn’t working. What could it be? After looking at the service manual I see it’s all leading to the speed sensor on the front and rear wheel. Appreciate any help getting this sorted

Abs sensor handles speedometer.

Thanks is it normal for the ABS light to be on?

No. It should go off after you travel about 10 feet. If it is on, one of your wheel sensors is unhooked, or not the proper gap from the tone ring on the rim hub. The traction control should not be functioning as well since it gets input from the abs sensors to.compare for wheelies and burnouts.

Thanks a lot for the quick response. Yea it’s not recording the kms, even when on the stands. I spun the front wheel and tried to let the rear wheel spin in gear but nothing. Abs lights always on cuz the bike doesn’t know it’s moving 🤦🏽‍♂️😅

Check both sensors for damage to the magnets and the gap. I don't remember off hand. Need to find it in manual. It's about 1.5mm.

I did more digging today. I noticed the sensor plates have a marking “B” (front wheel) and “c” ( rear wheel)
As per the manual they need to face outward. But mine were facing inward. So i flipped them but still the same issue.
the workshop that the bike was at removed the ABS module, installed normal race brake lines and put the sensor plate on the rims the other way round.
the ABS light is on but I’m not getting any fault codes. I spoke to the Yamaha shop and they said they don’t have a diagnostic tool for my bike. And apparently the ABS fault code needs to be reset and can only be done with the tool

The abs pump.block is missing or unhooked? Then the system doesn't work due to that reason. Trace the rear brake line under the frame/battery area. If it doesn't have a big block with lines in and out of it, the module is gone.

The abs pump was unhooked and all the lines removed. Racing lines were fitted. They didn’t use the abs delete plug so I’m guessing that’s the only fix at the moment. Going to try going back to stock lines and try again

 

[mordantly]

Yes the delete thing will fix the missing abs code. But the odometer speedometer I don't know if it will work.

 

[Incorgnito]

installing the abs delete plug should fix everything.

I connected the abs back to stock and now the abs light goes off as normal. But still the odo n kmh aren’t

I'm having a similar situation with you, my ABS plug is broken from a crash, so ABS light will always be on but I still had the speed and OD for 5 months, but suddenly the engine light comes on and the speed shows 0 and OD is freeze. I'm just sharing some info that I know and trying and get my 17 R6 fixes.
So here is what I found out, the speed reading is from the rear wheel sensor no matter front wheel is moving or staying still. I find out that from other crashed 2020 R6.
In the workshop manual suggest first replace your sensor if doesn't work, replace ABS unit. If still not working you have to replace the ECU...

Is your quick shifter working as normal?
