DSC Problem without warning light?
I will be having this problem looked into this weekend but wondered if anyone has had similar issues and what they did to fix. This is somewhat a carryover from my Engine Issue thread.
I have isolated the issue to the DSC. It seems that intermittently, the DSC will kick in. It's always at cruising speeds on the freeway where it's noticeable. It could be happening more often, possibly at lower speeds, but it would be harder to tell. Aside from something being unplugged which would undoubtedly call up a CEL, could a bad wheel speed sensor or steering angle sensor cause an issue that wouldn't trip a CEL? When the issue does occur, I can make it go away by turning off the DSC, so I know the issue lies there. |

After having this issue since the car was delivered, with the help of my good friend Mike Benvo, we finally figured out the issue. DSC was cutting in and out without warning or any lights on the dash due to the V2 steering wheel being installed incorrectly at the dealer. After determining that the steering wheel was showing an offset even when dead straight, I decided to remove the entire wheel and start checking things out. It appears that when the dealer installed the wheel when I bought the car, they didn't put the SZL back in correctly which was causing the DSC to intermittently come on and off because it was thinking that the wheels were pointed in a different direction than they really were. Once I installed the SZL and the wheel correctly and had the car recalibrated, the problem was finally gone. I am one happy camper now!

Correct me if i am wrong, but for what you explained the mistake was, this could have been potential very dangerous, right?

On a side note, I guess it sort of confirms the fact that DSC can do a quick intervention without flashing the light in the cluster... |

Yes, the DSC can definitely kick in and not just quickly either. It would intervene in 5+ seconds at a time depending on the situation. |

Interesting. Would be good to understand what is the DSC intervention threshold that triggers the DSC light.

Obviously with this case, we can see that the steering angle caused it. It had an 8 degree offset when the wheel was at center. This is why the DSC was normally being triggered when I was driving on a curve.

The reason for me asking, is that on many threads people are saying that if you drive smooth enough on a track, you will not engage DSC/MDM. So if the light does not flash, you are doing good. My counter argument was that I could feel DSC/MDM interfere without getting the visual warning. This could lead novice drivers overdriving their cars without knowing. Your thread seems to confirm my impression about not getting the visual warning. |

DSC will make slight corrections without triggering the light. It has to be a larger event to get the light to blink. If there is over or understeer detected, or if there is lateral movement or wheel spin, the light will engage. But it will engage in small quantities (say going over a decent sized pothole) without the light turning on. If you want to become a better driver driving with DSC on is a waste of time. Even US MDM mode is far too invasive in my opinion. Euro MDM is where it's at. When I coded Euro MDM mode to his car, the problem actually subsided in that mode. This shows the recalibration of the DSC system for a more spirted, exciting drive.
