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.
2. The ABS control unit operates the solenoid valve when the brake pedal is released after the initial diagnosis You may
hear the solenoid valve operate at this time, but it is normal
Pumo Motol
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 motor operate at this
time, but it is normal.
Brake Fluid Replacement/Ail Bleeding
L Brake fluid replacement and air bleeding procedures are the same as for vehicles without ABS To ease bleeding, start
with the front wheels.
Troubleshooting
1. The troubleshooting flowchart 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. 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 canngt be checked unless the check
conditions match with the problem conditjons
3. When the ABS jndicator does not come on during the test-drive. but troubleshooting is performed based on the DTC,
check lor loose connectors, poor contact of 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 illustratjons show the female terminals with a single outline and the male terminals with a double out-
l ne.
ABS Function Test
To simulate ABS operation and activate the solenoid valves and pump, use the Honda PGM Tester.
Connect the PGM Tester to the 16P Data Link Connector (DLC). When the System Select menu is displayed, select the ABS
Test Mode menu, and follow the tester's prompts.

Description
J)
The SRS is a safety device which, when used in conjunction with the seat belt, is designed to help protect the driver and
front passenger in a frontal impact exceeding a certain set limit. The system consists of the SRS unit (including safing sen-
sor and impact sensor), the cable reel, the driver's airbag and front passenger's airbag.
Seat Bolt Tensioner {'98 - 00 models}
The seat belt tensioner is linked with the SRS airbags to further increase the effectiveness of the seat belt. In a front-end
collision, the tensioner instantly retracts the belt firmly to secure the occupants in their seats
FRONT PASSENGER'SAIREAGDRIVER'S AIRBAG
FRONT PASSENGER'SSEAT BELT TENSIONER{'98 - 00 modelsl
)
SRS UNITDRIVER'S SEAT BELTTENSIONER l'98 - 0O modeb)
Operation
The main circuit in the SRS unit senses and judges the force of impact and, if necessary, ignites the intlator charges. lf bat
tery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power circuit
respectively will keep voltage at a constant level.
For the SRS to operate:
(1) The impact sensor must activate, and send electric signals to the microprocessor.
(2) The microprocessor must compute the signals, and send them to the airbag inflators (and seat belt tensioners).
(3) The inflators must ignite and deploy the airbags (and activate the tensioners).
Selt-diagnosis System
A self-diagnosis circuit is built into the SRS uniU when the ignition switch is turned ON (ll), the SRS indicator Iight comes
on and goes off after about six seconds if the system is operating normally.
lf the light does not come on, does not go off after six seconds, or it comes on while driving, it indicates an abnormality in
the system. The system must be inspected and repaired as soon as possible.
For battery serviceability, the memory will store the cause of the malfunction, and the data link circuit passes on the infor
mation from the memory to the data link connector (DLC). This information can be read with the Honda PGM Tester con-
nected to the DLC {16P).
