I apologize if this has been addressed before, I didn't take time to read all 1100+ post. Has anyone looked into a relation between battery voltage and the dess error? This spring I started to get the error occasionally. It became more frequent as time went by. Never had a problem starting after removing the key and reinserting. The end of July my battery died, after replacing it I have not had the error again. This may be totally unrelated, but could be a cause for at least some of the errors.
Hi 3Tyme,
When I started this thread (on 8/13/2015) I had the OEM battery and at the time the OEM battery voltage was normal. Also, I replaced the OEM battery in 2017.
At the time I had a 2014 RTS-SE6 (I sold that in May of 2023). When I had the D.E.S.S. The module changed on 7/14/2015, I had 6,994 miles. The 2nd time I had the D.E.S.S. The module and the Switch replaced was on Aug. 28th, 2015, and at that time my 2014 RTS-SE6 spyder had 8,740 miles.
On July 14th, 2015 the dealership replaced the DESS Module (part # 710004190) which was under warranty. I got from the dealership the following info saying why the DESS error happens: Roadster 2014-015 D.E.S.S Error Displayed in Cluster_000104494_ TST61Y014S10_en Summary: This TST explains the reason a customer may experience, intermittently a D.E.S.S error message in the Cluster.
TST Detail: Refer to TST Roadster 2nd Generation D.E.S.S Principal of Operation (2014 and Up) to fully understand the principle of operation of the latest D.E.S.S generation.
Problem: Intermittently, the ignition key may not be recognized causing the unit not to start. The D.E.S.S ERROR message will be displayed in the Cluster.
Solution Replace the D.E.S.S module.
Program the keys using the B.U.D.S. referring to the 2014 RT shop manual section Digitally Encoded Security System (D.E.S.S.)
Note: If after the replacement of the D.E.S.S module the problem reoccurs, update the previously opened BOSSWeb case or open a BOSSWeb Case and report this situation.
Technical Explanation:
When the D.E.S.S. module sends its signal to the antenna to read the key chip, the radio frequency produced by the antenna is too strong and the key chip is saturated. This saturation changes the data transmitted back to the D.E.S.S module causing a bad lecture of the key chip.
More info. Turn the key on/off IMMEDIATELY and DO NOT LET THE SYSTEM SHUT DOWN do that for about 4 to 5 cycles.
What Spyder do you have?
What year is your Spyder?
I hope the above info helps.
