DSC Sport Active Suspension Controller

[McTTRS]

Then within 5 minutes of the update, was going WOT to get on the tollway by my house and seemingly every warning light/message came on.

I have updated the DSC unit a half a dozen times or so without issue so based on my experience the two events may be totally unrelated.

Edit - I contacted DSC with your post and they said "Thanks for the info. I change calibration files all the time on DSC controllers and have not experienced what that user described. It is possible that he did something different that caused the suspension controller to freeze. In saldom cases, I have heard of people doing ECU flash that's followed by a hard reboot that draws a lot of battery power which can freeze the suspension controller if the battery itself isn't fully charged or in excellent condition to begin with. That user should contact us ([email protected]) for diagnosis..."
