Good whatever time of the day you have ladies and gents,

Had my tire replaced around a week and a half ago and had no issues until this past Monday on my way to work. Check engine light, ABS light, and the traction control light came on. Weird. I talked to a buddy of mine and we talked about a few things and he mentioned maybe the battery was on its way out, as that can cause some weird things to happen, regardless of car or motorcycle. So I replaced the battery and the spark plugs this evening, and the air filter was recently done in the last 3 weeks due to what felt like a slight miss over 100kmh and a suggestion by sbeart. While riding, I checked the voltage output based on the dash, and it shows a solid 14.7V throughout the range, so not a regulator problem from what I read on other threads. I did turn the bike over but haven't had a chance to ride it. Will take it to work tomorrow morning....in hopes the light goes out? Even when the lights were lit up, it rode just fine with no loss of power or anything of that nature. The spark plugs looked normal with no signs of lean or rich conditions, just a PITA to get to. Need child size hands to get in there.

Any thoughts?

On a longshot you could check to see if there's a reset procedure for your ABS. Sometimes after changing the tire you need to reset. If necessary there should be a procedure in the manual. I had to do it for my GTS. Good luck

Hoping they did not bend or damage the abs sensor or abs ring when taking the rear wheel off

@Afflicted - there is a procedure and I may give it a shot.

@Flybynight - I did take a look at the sensor, the wiring, and the ring and all looks to be intact. I will take a closer look at it tomorrow.

I am kind of amazed that the ABS/ASR would trigger the check engine light though. Typically the check engine light would be something related to the engine management in some way, shape, or form and the ABS/ASR light would be only related to the ABS system.

Appreciate your feedback and things to check.

Most times a check engine light is related to emissions. I'd check the O2 sensor first and foremost as it is a wear and tear item with a very finite lifespan.

Also check/measure the 3 legs or AC phases on the stator. IF one or more legs are getting weak it can play tricks on the electronics.

Did you recalibrate the ASR after the tire was replaced per the procedure in the owner's manual??? ASR does influence throttle control so there is a engine connection as well.

I didn't reset the ASR after the tire change. I was going to wait until I wore the tire in over 50km and then reset since there is that initial coating on the tire after being made.

I will check the other two items as you stated when I have the time, assuming the rain stops at some point. Is it just one O2 sensor or two?

Thanks again.

Just in case you do not have the manual with you

IN THE EVENT OF MALFUNCTION OF
THE BATTERY, THE ABS - ASR SYS-
TEM TURNS OFF.

In order to maintain the effectiveness of
the ASR system following the replace-
ment of one or more tyres a calibration
procedure of the system must be per-
formed as follows on a straight flat stretch
of road.
• It is necessary that the diagnostic phase
of the ASR systems and ABS is com-
plete: for this purpose, after switching to
«ON», ride a short distance above 5 km/
h and wait for the flashing of the two
warning lights to stop.
• Allow the engine to idle for at least 5
seconds.
• Pull the brake lever and press the ASR
on/off button «1» simultaneously for at
least 3 seconds. The activation process
will be confirmed by the ASR warning
light «2» turning on with slow flashing.
• Accelerate to a constant speed of 30 to
40 km/h and maintain it for at least to 8
seconds. The continuity of the vehicle
speed in the correct field to complete the
procedure will be confirmed by a very fast
flashing of the ASR warning light «2».
• The end of the procedure will be indica-
ted by the steady lighting ASR warning
light «2». The ASR system is not active.
• Once the procedure is complete it is
necessary to switch to «OFF» and wait
for at least 60 seconds before being able
to switch again to «ON».
• In case of failure to complete the proce-
dure within 5 minutes the ASR warning
light «2» will stay on steady and the ASR
will remain off until switching to «OFF».
• To switch again to «ON» it is necessary
to reactivate the ASR. It is however nec-
essary to repeat the process until it suc-

No luck. Lights are constantly on. Going to hit up the dealer and see what they can tell me sinc i don't have a way to diagnose the codes.

Thanks for the suggestion.

So, the problem was the ABS sensor. The tire place didn't route the cable correctly and it rubbed through the sensor. Guess i will be taking the bill to the tire shop and seeing if he will pay me back for his fault or cut a deal on a new set of tires.

Thanks again for the ideas to check. Great community we have here.

BTW, because that was passed through the ECU, the ABS sensor triggered the check engine light. Dealer was able to show me the diagnostics from the computer and ran the scan for me to see. Hope this helps others.

Absolutely.

There is a channel which the sensor cabling passes through on the swing arm. I thought something looked out of place, but since I never pay much attention to the sensor back there, I didn't think twice about it unfortunately. The total cost for sensor and install was around 150 bucks total. No part of the sensor cable should be looped our hanging out in any way. It should run flat against the swing arm and behind the plastic shield that protects it. For those with ABS and have your back tire swapped, ensure that you check it prior to riding.
