Confirming the Function

1. Shifting to the sleep mode:

1) Turn the ignition switch OFF.

2) Cancel the key-off operation timer in power window system by opening and closing one of the front doors.

3) Make sure that the trunk is closed, and exterior lights are off.

4) If you do not operate the switches related to the multiplex control units more than one minute after meeting the

above conditions, the system function shifts to the sleep mode.

(All of the switches must be turned OFF except door lock knob switches, ignition key switch, audio switch, and hood

switch.)

2. Confirming the sleep mode:

1) Check for voltage between the wake up line (PNK/BLU wire between driver's and passenger's control unit).

There should be no voltage with the sleep mode OFF.

There should be battery voltage with the sleep mode ON.

2) Check for voltage between each communication line and body ground while shifting to the sleep mode. There

should be no voltage.

3) Check the parasitic draw at the battery while shifting to the sleep mode. The ampere should change from 100 mA to

less than 100 mA.

3. Confirming the wake up mode:

After confirming the sleep mode, turn the related switch (see previous table) ON, and wake up each control unit. If all of

the operations works properly, the wake up mode is OK.

(If any of the control units are faulty and cannot wake up, several parts of the system will not work at the same time.)

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
