BRAKES AND DYNAMIC POWER STEERING QUESTION

[Bmac]

Does riding your brake pedal have anything to do with your Dynamic Power Steering ? Seems like I read a post about the brakes and DPS system but cannot find it now . THANKS

Riding the brake pedal will cause the VCM to go into Brake Failure mode. That will shut down ABS and vehicle stability functions. Which will cause the ECM to go into Limp Home Mode. Spyder speed and engine rpm will be limited for rider safety. I do not believe it will do anything to the DPS.

i rode the brakes awhile back on a curvy downhill...while I was rolling on the throttle. I got a DPS failure. I stopped, shut down, started up, and all was ok. I did this again, same road, but this time on purpose. Same result.

It would be interesting to understand the actual mechanics of how that fault was triggered. Which box and why?

As I see it..!!

having the drag on the front wheels while applying the brakes for extended periods can affect the steering and send a code about the dps. Having as many sensors and techy stuff they do get crossed up it seems. But it all works well....:thumbup:

The brake fault can cause a VCM warning, which in turn shuts down all VSS related functions...including the DPS. You can then get a secondary DPS warning. This was quite common when the Spyder was first introduced. Subsequent ECM and VCM updates have made it less sensitive.

Everyone should know, the first time I did this, it was within the first 500 miles that I had on the Spyder. I then checked the posts here on Spyderlovers and learned the cause was "driver error", so to speak. After that I did it on purpose to test that what I read really did match my situation. It DID match, and I focused on changing one of my bad driving habits. It has not happened since.

This is not an ongoing problem, and the reason I posted my experience is that I thought that someone could learn from my experience, just like I learned from others. It is due to the many, kind, knowledgable, and friendly people here that I've been able to learn as much and it has enhanced my enjoyment of the Spyder.
