i have a 94 integra and went the car is idling, ever so often, (i think its the ABS) makes a sound and vibrates for about a second..

anyone have any ideas why or what might be wrong?
thanks

 

mine does the same thing

 

Same here. I think its normal.

 

is your abs light on? there is a tsb on the abs system for 94+ integras. check the fluid level and add if needed, or try bleeding the system.

 

yeah, if ur abs light is on, then maybe its low on fluid. other than that the noise is normal, Mine does it too. Its jsut the pump pressurizing.

 

abs light is not on...fluid level is fine

 

Thats the sound of a stepper motor within the ABS unit working to keep the pressure in your brake system within a certain range. As long as your ABS light is off, or your not having any braking issues I'd say your fine.

Generally you'll hear this after starting your engine or briefly during idle.

 

 

mine doesnt do it but my buddy's does. weird its cool sounding tho!
