I've intermittently had this combo of idiot lights triggered the past few weeks. Generally goes out on next re-start. What's crapping out?

It's disabled, you can do that manually by holding in the DSC button so, I'm a assuming you cold have something wrong in one of the modules but don't know for certain.

Exactly what I was thinking. Perhaps a sensor is going out, or has a loose connection?

Sounds like the fault I had a month or so ago. It was the ABS pressure sensors starting to go. Not a cheap repair. :(

Could be wheel speed sensors, or perhaps an alignment that's too far out of whack. ABS sensors as mentioned, though I haven't heard of this one (I thought ABS got its signal from wheel speed sensor?).

Yikes. Like as in how not cheap? Definitely not alignment, it's spot-on.

Did some Googling. Seems that the ABS light in addition to these would be worst-case scenario. No ABS light might be smaller problem, like wheel speed sensor. It's been intermittent for weeks, will get it to the shop when convenient and will report back here as to what the culprit was. Thanks all!

See the thread titled DSC light in mechanical. Also pull the codes that's what sent my Indy down the path and he was correct first try.

Kevin,
Read this, I had the same, senior tech told me its ABS sensors 95+% of the time, he even wagered a free repair if he was wrong. He was spot on, think the bill was between $800-900. No recurrences since the repair, car brakes better now.
