95 Acura integer makes a plastic buzzing sound for 15-60 seconds after startup. Sound eventually stops. Sound is originating from white box:

The goal is to understand the cause of the sound and corrective action. What are the steps to diagnose root cause of the sound? Any lessons-learned or relevant experience is always appreciated.

  • The white box you're looking at is the ABS module. The noise will probably be related to the ABS warning light you asked about in this question

This is the brake fluid tank. Underneath it likely has the ABS actuators, which likely make the sound you are hearing. I'd start by diagnosing ABS (with a scanner). If you don't have the scanner that can diagnose ABS - pull the ABS fuse and start the car to see if the sound is still there.

  • Thank you for responding. Are you able to provide a link to a ABS scanner? I ask because I am trying to understand if it is ODB tip scanner or a scanner specifically used only for ABS. Unfortunately the '95 misses the cut for the ODB2 compliance mandate

  • @gatorback, yes, unfortunately '95 Integra does not appear to have OBDII. Here's a link to an forum post explaining how to pull codes on Acura without OBDII. team-integra.net/threads/abs-codes-94-97.173389
