Yes to both conditions if I recall well. Not on ZR-1's, but the regular coupe even got a big upgrade in 95,96 to a faster acting system with updated control. The C4's ASR was capapble of applying a rear brake along with throttle reduction to stop spinning tires and to induce a yaw correction in a sliding condition. The inputs should be individual wheel sensors, the yaw sensor in the depths of the console or ABS well (don't recall). The lack of a speedo signal may very well be part of this mystery- i would try to fix that regardless.

The year of the car was never mentioned so it would have to be a 92-95 model to have ASR. if it is a 90 or 91, all this is moot- ABS only and shouldn't be able to lock up a wheel...but who knows for sure.
