Hi,

I have a 94 civic EX. It doesn't leak any brake fluild, the reservior is full.
The ABS light usually goes off pretty quick, but it buzzes all the time until it's warm.
It seems to buzz for 4 +/- seconds, every 1-2 minutes, for 10-20 minutes.

I've read it is supposed to self test, but is this normal? If not, any suggestions on what to try?

Thanks.

 

be sure that your master cylinder and the resevior on the unit are both filled up to the correct level. I think the civic unit is the same as the integra or similar and I had a 95 teg before and I had this problem
