Description

SRS Airbag System - '96 - 98 Models

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 Belt Tensioner

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.

Operation

The main circuit in the SRS unit senses and judges the force of impact and, if necessary, ignites the inflator charges. If battery

voltage is too low or power is disconnected due to the impact, the back-up power circuit will keep voltage at a constant level.

For the SRS to operate:

(1) The impact sensor and safing sensor must activate and send electric signals to the microprocessor.

(2) The microprocessor must compute the signals and send signals to the airbag inflators and seat belt tensioners.

(3) The inflators must ignite and deploy the airbags and activate the tensioners.

Self-diagnosis System

A self-diagnosis circuit is built into the SRS unit; when the ignition switch is turned ON (II), the SRS indicator light comes

on and goes off after about 6 seconds if the system is operating normally.

If the light does not come on, or does not go off after 6 seconds, or if it comes on while driving, it indicates an abnormality

in the system. The system must be inspected and repaired as soon as possible.

For better 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).ProCarManuals.com

CAUTION: Whenever the ignition switch is ON (II), or has

been turned OFF for less than 3 minutes, be careful not

to bump the SRS unit or the side impact sensor; the

airbags could accidentally deploy and cause damage or

injuries.ProCarManuals.com

6. Reconnect the airbag connector(s):

Front Passenger's Airbag:

• Connect the front passenger's airbag connector to

the SRS main harness connector, then install the

glove box.
Driver's Side:

• Connect the driver's airbag 2P connector to the cable

reel 2P connector, then install the access panel on the

steering wheel.

7. Reconnect the battery positive cable, then connect

the negative cable.

8. After installing the airbag, confirm proper system

operation:

• Turn the ignition switch ON (II); the SRS indica-

tor light should come on for about 6 seconds and

then go off.

• Make sure horn button works.

• Take a test drive, and make sure the cruise con-

trol switches work.

9. Enter the anti-theft code for the radio, then enter the

customer's radio station presets.

tive cable.

13. After installing the seat belt, confirm proper system

operation: Turn the ignition switch ON (II); the SRS

indicator light should come on for about 6 seconds

and then go off.
