Hi,

It's a 94 civic EX. It doesn't leak any brake fluild, the reservior is full.
The ABS light usually goes off pretty quick, but the ABS unit buzzes all the time until it's warm.

It buzzes for +/- 4 seconds, at first every minute but becoming less frequent, for like 10 to 20 minutes.

I've read the noise is the ABS self testing, but how often is normal?
If this is over doing it, do you have any suggestions?

Thanks.
