I didn't post this at the time, but I thought I'd share an experience we had on the way back from the Coast last weekend.
Kim had driven there, and I drove back. Keep in mind that when I bought the SLE, traction didn't work, but ABS did. So I always get a traction off light after driving the first minute or so. CCR has always worked.
About halfway back, I noticed when I glanced at the gauges that my traction light was OFF. Pulled over, hammered it on the hard shoulder, and sure enough, I couldn't get more than a chirp. Happened to look things over and saw BOTH CCR lights were on.
About 10 miles later, looking things over again, Traction was back off again (and hasn't worked since), and CCR was working again. has ever since.
I may have relatively small issues with both systems, and I'll betcha it'* related to a ground common to both systems, since they have nothing else in common.
