Intermittent ASR and ABS Light Problem
On occasion, my ASR and ABS lights will come on, but the don't do it all the time. They always come on at the same time too. It's only when I'm under hard breaking, and even then it only does it sometimes. I can turn the ignition off, and restart the car, and the lights go out till the next time they decide they wanna be seen.
My guess is that what ever's causing it is something that's common to both functions, so I'm thinking maybe a sensor on the wheels or something?
Any suggestions at all would help. I'm working on my '92 vert.
Thanks!

When mine did that, I was low on brake fluid. Filled the fluid, no further problems

Check the obvious things brake pad wear, fluid level, etc.
The owners manual does say if it happens as you describe just cycle the ignition.
If it continues pull the codes and see if it is setting a DTC.

Low fluid level is most likely the culprit. Even a 1/4" low in the MC reservoir will be enough to trigger the two lights. You may or may not see the "Brake" light come on but do check the fluid level.
Bring it right up to where it is just below the top of the reservoir. There should be a molded bar on the outside of the reservoir that is the FULL line.

Brake fluid!!
It looked 100% full to me, but every autocross run both lights would turn on and I'd lose ABS. Filled the reservoir just over the top of the fill line and it's been flawless since.
