Honda Civic 1998 Service Manual page 877

Kickbsck
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.
2. The ABS control unit operates the solenoid valve when the brake pedal is released after the initial diagnosis. You may
hear the faint solenoid valve operation sound at this time, but it is normal.
Pump Motor
1. The pump motor operates when the ABS is functioning.
2. The ABS control unit checks the pump motor operation during acceleration. You may hear the faint operation sound
at this time, but it is normal.
Brake Fluid Replac€ment/Air Bleeding
1.
Brake fluid replacement and air bleeding procedures are same as conventional brakes.
Troubleshooting
1. The troubleshooting flowcharts explain the procedures on the assumption that the cause of the problem is still pre-
sent and the ABS indicator light is still on.
Note that troubleshooting following the flowchart when the ABS indicator light does not come on can result in jncor-
rect judgment.
Ouestion the customer about the conditions when the problem occurred, and try to reproduce the same conditions
for troubleshooting.
Self-diagnosis is made at various times such as the initial diagnosis, except ABS control, during ABS control, during
acceleration, during the specified vehicle speed, etc. Therefore. the symptom cannot be checked unless the check
conditions match with the problem conditions.
When the ABS indicator light does not come on during the test-drive, but the troubleshooting is performed based on
the DTC, check for the loose connectors, poor contact of the terminals, etc, before troubleshooting.
After troubleshooting, erase the DTC and test-drive the car. Be sure that the ABS indicator light does not come on.
The connector illustrations show the female connectors with a single outline and the male connectors with a double
o u I | t n e .
The connector terminal cavities containing female terminals are always numbered by looking at the connector from
the wire side, and the cavities containing male terminals are always numbered by looking at the connector from the
terminal side.
