My wife's 96 Accord 6cyl ex is making buzzing sound at start up. Sometimes after 60 seconds of the buzzing sound, then the ABS light comes on. I guess ABS is disable at that point. Sometimes after 10 seconds of buzzing, then the noise stop. Everything seems fine. There may be air in the ABS system?

What's the proper procedure to bleed it? I know how to bleed the normal front and back disc brakes. TIA.

 

If the 6cyl is like the 4 cyl model. There are 2 brake resevoir for the brake system. 1 for the ABS and 1 for brake. If you search in the archives of how to bleed ABS system, you'll find the answer.

But first check...
-How much fluid do you have in your ABS resevoir and the primary one. But the system does make a noise when you start the car. But 10 secs is a lot of time.

 

That or you may need to run a diagnostic on the ABS system, it may not actually be the brakes. I believe autozone does it with a padel commander for free.

 

If there is an answer in the archive, it is hiddened quite well. I found many posts about ABS and RotaryBzzz's famous $1.51 fix for your ABS modulator.

The fluid did not leak out, stays the same level. Only buzzing sound at starting (from the ABS pump ), then ABS light comes on sometimes.

I did go through a series of bleeding activities last night. It appears to have fixed the problem. I would like to hear a proper procedure to bleed the modulator. I will, however, disclose my experience with it later. I just don't believe I had the correct (official) procedure, just got lucky. If the problem doesn't come back, I will detail my experience later.

So, if you know how, please enlighten me.
