So, my ABS doesn't work, and hasn't since I got the car from my grandparents in August. Im fine with this. What bothers me is that when I start the car there is a really loud buzzing for 10-20 seconds, and then the ABS light comes on. Since I was quoted around $1200 to replace the ABS system, I am more eager to find out how I can just have it not make the annoying sound at start up. Is this as simple as just removing a fuse? Im fearing that it is not, but please inform me as to what I need to do.

sweet something i can answer with confidence hehe jk. mine did this too.ok what this buzzing is is the pump trying to pressurize the abs system. there is a small gasket that is cracked and leaks thereby not allowing the system to gain the sufficient pressure to work properly. the abs system is designed to disengadge afte 15 seconds if pressure is unreachable. so yeah pull the abs fuse and the noise goes away. the abs light will be on forever though. 1200 is rediculous. the whole system doesnt need to be replaced. one just needs time to locate the gasket and replace it. i took apart an abs system layin around the shop just to see how much trouble itd be and its a pain the the butt while the pump is on the car. therefore i pulled my fuse. problem solved.

The sound you hear when you first start your car is the ABS system pressurizing. This only pertains to '94-'97 Integras, because they have a different ABS system from the '98-'01 Integras and '97 Type-Rs. The '94-'97 Integra's ABS system has a seperate brake fluid reservior (#3 in diagram). The ABS brake fluid should be bleed and flushed periodically to remove air from the system. If you hear the buzzing for more than a couple of seconds (~2-5 sec.), this is a good indication that the ABS system needs to be bleed. Now if you hear the buzzing for ~60 seconds and then it shuts off and the ABS light comes on, it means that the ABS system could not be pressurized and the ABS has been disabled. The main cause is a small rubber O-ring (#23 - part # 57072-ST5-003) which seals the brake fluid ACCUMULATOR (#2) which is under extremely high pressure. If this O-ring fails brake fluid will leak out and you will see it under the ABS module.

Here is a diagram of the '94-'97 Integra ABS module:



========================================

Here is the procedure for ABS brake fluid replacement and bleeding for '94-'97 Integras only (from the Helms manual):

1.) Remove the bleeder cap from the maintenance bleeder on the modulator unit.

2.) Attach the wrench to the maintenance bleeder.

3.) Connect a rubber tube of the appropriate diameter to the maintenance bleeder, and set the other end of the rubber tube in a suitable container.

4.) While holding the rubber tube with your hand, slowly loosen the maintenance bleeder 1/8 to 1/4 to collect the brake fluid in the container.

CAUTIoN: Do not loosen the maintenance bleeder too much. The high-pressure brake fluid can burst out.

5.) Tighten the maintenance bleeder.

6.) Start the engine and let it idle for a minute. Stop the engine.

7.) Check the brake fluid level in the reservoir. It should be below the MAX (upper) level line.

8.) Repeat the steps 4 through 7 to drain the rest of the brake fluid from the modulator unit.

9.) Remove the cap, and refill the reservoir to the MAX (upper) level with fresh brake fluid.

10.) Repeat steps 4 through 8 twice, and refill the reservoir to the MAX (upper) level with fresh brake fluid.

11.) Tighten the maintenance bleeder to the specified torque (8 lbf-ft).

12.) After replacement, start the engine and make sure that the ABS indicator light goes off.

Note: this ABS bleeding procedure only applies to '94-'97 Integras. The ABS system on '98-'01 Integras is different (ie. it does not have a seperate brake fluid reservior for the ABS system) and does not require a seperate bleeding procedure for the ABS system.

can someone fix the link? i wanna see where the brake fluid resevoir is at..
