DESS Key code again!!!!!!!!!!!!!!!!!!!!!!!

[helton61]

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.

Hello you should start a rental program charge a fee you would soon get your money back i will be your first customer.

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 nojoke 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 triggers a DON'T START signal in the ECM if/when it doesn't read the correct code from the key, so by turning the DESS OFF, it can never trigger that DON'T START message, and therefore the engine will start EVERY TIME! hyea: Simples really! :thumbup:

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.

crusinTX,


Would other people chime in on this?

Deanna, did you not read Peters explanation just a couple of replies prior?

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



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.

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!

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

Sorry, won't work. One of the criteria for the ECM to permit engine start is "D.E.S.S. recognizes the key." If you simply cut power to the DESS module the ECM will not get the key info from it. If the ECM can't get the key info from the DESS it won't give the OK signal to start the engine. That's why the only way to "Disable the DESS" is to use BUDS to change the parameter inside the ECM so it skips the valid key check.

Keep in mind DESS doesn't mean only the module but also the software program. It's Digitally Encoded Security System.

I thought I had already posted this but guess not. I need to thank James Thorne from Houston, Tx. for having exorcised the DESS gremlins from my 2014 RT-L when we met up in Las Vegas, NM on Friday, June 23rd. Hoping that is the last I ever see of that worthless piece of technology built in by the "oh so brilliant BRP engineers."

Please tell everyone here who did it ...... EVERYONE wants to know this .... it gets asked a lot here .....Thanks .... Mike :thumbup:

Wow, 44 pages of this. DESS error twice on my nearly new 2022 F3s.

Hopefully " BRP Cares " doesn't read Your post. .... Dis-abling DESS isn't something BRP would tolerate - -JMHO ..... Mike :thumbup:

If they had half a brain they would do something different! Oh wait, that would mean someone won't make any money, silly me what was I thinking!
