RS SM5 Q & A session

[docdoru]

My Spyder @ 87K had this symptoms:
1. ryde 10 min, error codes (VSS Error, Check DPS, Limp Home Mode)= maximum 39 mph and 3500 RPM.
2. quick turn key off and on: Check DPS Error, unlimited mph and red line for the RPM; after 20 min, back to (1).
Note: DPS replaced few days ago.

[QUOTE=docdoru;231236]My Spyder @ 87K had this symptoms:

After I did a front end alignment I got the same codes until hooked up to BUDS and had the torque and steering angle sensors reset . I don't know if your front end has gone out of alignment but I remember you had trouble with a bent pin or bushing on your rear Elka shock.

Also when I was in Limp Home Mode when I got into 5th gear at about 3500 RPM I was going 79 KPH ( about 48 MPH )

Don't know if it matters but I have a 2009 SE5

Steering angle sensor reset properly. Alignment is specs.

Can be a SE5 also.

I've read some post that they are getting bad DPS and they are using rebuilt ones as well . May-be you are one of the unlucky ones and have another bad DPS

DPS is fully functional, all DPS updates installed.

No active codes while in limp mode?

None in the B.U.D.S.

Serious warnings and limp mode should not be able to be triggered without leaving a fault behind. If BUDS is clean, I would suspect:

1. Low battery voltage
2. Loose or bad relays
3. Loose or corroded wiring connector somewhere...even to a single sensor
4. Faulty module (VCM, ECM, or cluster)
5. RFI interference
6. Interference by an aftermarket accessory

The fact that this happens when warm would tend to point to a processor or circuit board issue, i.e. bad module. Just guesswork on my part. These types of things that leave no tracks...even when they should, can drive you nuts. You might need to call in one of the wizards at BRP tech for help. Kurt, are you listening?

6. Interference by an aftermarket accessory

Close, but which one?
I agree, it did drive me nuts together with 4 Tampa Bay service mechanics....until today at 6 PM...

Radar detector

Radar detector

...Nope.
One more clue: you don't need any tools for diagnostic...

[fastfraser]

Loose relay ?

[docdoru]

Loose relay ?

No...

Custom seat, seat switch disconnected?

Don't keep us in suspenders

[docdoru]

Custom seat, seat switch disconnected?

No...I was in suspense for a week and 3 days prior to a ryde to Canada...

MCC or GPS?

MCC or GPS?

And the winner is...Rando: MCC!

The 2 nickel plated magnets are normally placed in the heads of the bolts that mount the ABS tone wheel. For unknown reasons, they slip towards the VSS reading area...

I had the same basic thing going on with mine many moons ago. It turned out to be that the negative battery terminal was not torqued down enough.

In your case, the Limp Mode is different: max 45 mph and 4500 RPM...same in double brake lights bulbs burned...

What is the MCC?
