Bleeding

1. Fill a container with 5W - 30 or 10W - 30 engine oil,

and place the hydraulic tappet in it. Press down on

the check ball with a thin wire. Bleed the tappet of

air by pumping the plunger slowly until no bubbles

come out of the hydraulic tappet.

Inspection and Adjustment

Bleeding

CAUTION:

• Always use Genuine Honda DOT 3 Brake Fluid. Using

a non-Honda brake fluid can cause corrosion and

decrease the life of the system.

• Make sure no dirt or other foreign matter is allowed

to contaminate the brake fluid.

• Do not spill brake fluid on the vehicle, it may damage

the paint; if brake fluid does contact the paint, wash

it off immediately with water.

NOTE: The reservoir on the master cylinder must be at

the MAX (upper) level mark at the start of the bleeding

procedure and checked after bleeding each brake

caliper. Add fluid as required.

1. Make sure the brake fluid level in the reservoir is at

the MAX (upper) level line.

'96 - 97 models: '98 - 01 models:

MASTER CYLINDER

2. Have someone slowly pump the brake pedal several

times, then apply steady pressure.

3. Loosen the brake bleed screw to allow air to escape

from the system. Then tighten the bleed screw

securely.

4. Repeat the procedure for each wheel in the sequence

shown below until air bubbles no longer appear in

the fluid.

5. Refill the reservoir on the master cylinder to the

MAX (upper) level line.

Self-diagnosis

1. The ABS control unit is equipped with a main CPU and a sub CPU, that check each other for problems.

2. The CPUs check the circuit of the system.

3. Self-diagnosis can be classified into 2 categories.

Initial diagnosis: Performed right after the engine starts and until the ABS indicator goes off.

Regular diagnosis: Performed right after the initial diagnosis until the ignition switch is turned OFF.

4. When a problem is detected by self-diagnosis, the system:

Turns the fail-safe relay OFF

Turns the solenoid valve OFF

Turns the pump motor OFF

Turns the ABS indicator ON

Description

Operation in normal condition

The ABS control unit turns the system off when the control unit detects a problem.

If the ABS control unit detects a malfunction during an emergency stop, it will turn off the malfunc-

tioning component, and continue to modulate the rest of the ABS system until the vehicle comes to

a stop. At that, the entire system will be turned off until the problem goes away.

The ABS control unit stores a DTC in back-up memory when it detects a problem. If a problem is

detected when the ignition switch is turned ON (II), the ABS control unit will turn the system off. If

the problem goes away, the ABS control unit will turn the system on again.

The ABS control unit will turn the system off if ignition voltage drops, and will turn on again when

ignition voltage returns to normal.

On-board Diagnosis Function

The ABS control unit is connected to the 16P Data Link Connector.

The ABS can be diagnosed with the Honda PGM Tester.

The ALB Checker cannot be used with this system. For air bleeding, and checking wheel sensor signals, use the Honda

PGM Tester. See the Honda PGM Tester user's manuals for specific operating instructions.

Troubleshooting Precautions

Kickback

1. The motor operates when the ABS is functioning, and the fluid in the reservoir is forced out to the master cylinder,

causing kickback at the brake pedal.

Pump Motor

1. The pump motor operates when the ABS is functioning.

2. The ABS control unit checks the pump motor operation during initial diagnosis when the vehicle is started. You may

hear the motor operate at this time, but it is normal.

Brake Fluid Replacement/Air Bleeding

1. Brake fluid replacement and air bleeding procedures are the same as vehicles without ABS. To ease bleeding, start

with the front wheels.

Troubleshooting

1. The troubleshooting flowcharts procedures assume that the cause of the problem is still present and the ABS indicator

is still on. Following the flowchart when the ABS indicator does not come on can result in incorrect diagnosis.

2. Question the customer about the conditions when the problem occurred, and try to reproduce the same conditions

for troubleshooting.

Find out when the ABS indicator came on, such as during initial diagnosis, during ABS control, after ABS control,

when vehicle speed was at a certain speed, etc.

3. When the ABS indicator does not come on during the test-drive, but troubleshooting is performed based on the DTC,

check for loose connectors, poor contact at the terminals, etc. before you start troubleshooting.

4. After troubleshooting, erase the DTC and test-drive the vehicle. Be sure the ABS indicator does not come on.

5. The connector illustrations show the female terminals with a single outline and the male terminals with a double outline.ProCarManuals.com
