D.E.S.S. Key code again!!!!!!!!!!!!!!!!!!!!!!!

[alexf415]

I just had the Check Key message today with my 2020 Spyder F3S with 1800 miles... After towing it home that caused me $250. If disappeared right after the spyder was dropped off my driveway...

[alexf415]

I DIS-AGREE with this post...I had 3 DESS modules replaced and 1 complete ignition switch with antenna...AND still had DESS issues...Only after having a forum member turn it off did my issues disappear...

SO MY RECOMMENDATION IS; HAVE THE PIA TURNED OFF AND LIVE HAPPILY EVER AFTER...larryd

What do you mean PIA???

Yes, those with earlier model years were fortunate not to need disabling the DESS as the DESS worked without fault. Can Am changed a system that worked fine in previous years to a few years of problems.

If you read the majority of this topic, 99.9% is focused on 2014 and later Spyders, and the person that started this topic does have a Spyder within that range of years.

My 2020 Spyder F3S with 1380 miles showed the fault "Check Key" today. After 2 hours of trying everything I called the towing company that charged me $250 just to bring my spyder 4 blocks away from my house. Right after my spyder was dropped at my driveway, the Check Key fault disappeared...

I think what he was trying to say is if you are ok with the possibility of being stranded out on the road because of this safety item keep it hooked up! If just taking your key out of the bike doesn't deter, someone from stealing your bike, then having this unit on this bike stopping you from using your key out in the woods somewhere is a PITA, and the crook will still take your ride if he wants it!

PIA = Pain In 'A part of your anatomy where you normally sit'!

But we all try to comply with Forum Rule 4 that says something like: Don't Bypass site filters for swearing, yada yada yada.

Does anyone have a wire diagram of the DESS module? I have a theory I want to test out on my 2014 and it would save a ton of time if I knew what wires went to what. Thanks!

PartsBob79,

I don't have a wire diagram of the DESS module, but I think someone should chime in on this.

Good Luck!

If you get the DESS error on your 2020 F3 S, the DESS module/Antenna/switch should be covered under OEM warranty and the B.E.S.T warranty. I had the DESS module changed twice (all 3 were covered under OEM warranty) and had the Antenna replaced twice.

If you get the DESS module replaced, would you please post the part number?

I don't think I will go that route anymore. The dealership gave me an appointment date of June 12. I can't wait that far while my Spyder is parked at my driveway with sunny weather. Meanwhile according to my email, my buds2 with Megatech for 1 year is arriving this weekend.

I have been getting the Check Key notice for a couple of weeks now.

I am just trying to help. OK. Good luck with your buds2 and with the Megatech.

I have been getting the Check Key notice for a couple of weeks now. Have an appointment for 9AM on the 25th at the local dealership to get it disabled. While on the phone, they didn't seem to have a problem with doing it the way I want. We'll see what happens next Thursday.

cruisin TX,

I thought that the dealerships can't disable the DESS. Keep us posted!

Most won't ( BRP rules ) or Can't ..... but if they are willing and have the Megatech license .... well maybe they will ....... if they do .... don't Advertise the fact .... JMHOP .... Mike

Ok Today I disabled the DESS on my 2020 F3S. Oh my goodness. That easy... I am now willing to ride again this beautiful Spyder. I have the megatech license for a year.. I'm from Seattle area in Washington state. wink. wink.

So will PITRA pass muster here. Thats - Pain in the rear anatomy?

[cruisinTX]

My appointment came and went without any happiness this morning. The service manager gave it a shot with two different systems at his disposal and said neither one would allow him to click on the disable icon in the DESS section of the system. He said the icon was there but had the familiar red circle & bar over it. At least he tried and sent me on my way no charge. Not sure what to do next except hope I don't get stranded somewhere. On a positive note; I was using a "new" key that had been hanging in our key closet since purchase instead of the original that is now 9 years old. He said continue on with that one and maybe keep the other new one in my pocket as a back-up but leave the old one at home. He also opened a case with BRP on the issue to see if they might authorize an override in the computer or have some other insights as have been discussed here on SL.com.

cruisinTX,

I am glad that the dealership opened up case with BRP.

Good Luck!

Keep us posted on what happens.

I've started reading this entire thread from the beginning to acquire as much knowledge as I can about this problem. The one big question I currently have is, when was it discovered that disabling the DESS would solve the problem? From what I've read up to page 10 so far is that the DESS sends signals to the ECM so the ECM can decide whether or not to allow start up. If the DESS is disabled then the ECM gets no signal, how does that allow it to approve starting the engine or not?

The DESS effectively sends a STOP signal to the ECM if/when it doesn't read the correct code from the key, so by turning the DESS OFF, it can never send that STOP message, and therefore the engine will start EVERY TIME! Simples really!

[cruisinTX]

That makes more sense now. I just need to find someone closer to home to do the delete for me. Doesn't seem to be anyone near Amarillo who can do it.

I'm not sure I agree with Peter's description. Look at the following extract from the 2014 service manual.

DESS & ECM.jpg

All the DESS does is transfer the key code to the ECM which compares the code with the list of stored codes. If it matches one the ECM allows the start to occur. If it doesn't match then the ECM prevents starting. I believe when the DESS is disabled it actually is not a disabling of the DESS process. What disabling does, I believe, is change the computer code in the ECM so that it does not do the comparison but always allows the start sequence to take place. "Disable the DESS" is not an accurate description of what actually is done. It's more like "Disable the ECM from doing the allowed keys check." Disable the DESS is just a simpler way to say what is done.

hmmm, you must be thinking the same thing I am. Find the power wire to the DESS and simply diconnect it.
