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

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).

within four seconds.
7. The SRS indicator light indicates that the memory is
erased by blinking two times.

Troubleshooting Intermittent
Failures
lf there was a malfunction. but it doesn't recur, it will be
stored in the memory as an intermittent failure, and the
SRS indicator light comes on.
After checking the DTC, troubleshoot as follows:
1. Read the DTC (see "Reading the DTC").
4.
Erase the DTC memory (see "Erasing the DTC
Memory").
With the shift lever in neutral, turn the ignition switch
ON (ll), and let the engine idle.
The SRS indicator ljght comes on for about six sec-
onds and then goes off.

lt--- _l
Shake the wire harness and the connector, take a test
drive (quick acceleration, quick braking, cornering),
and turn the steering wheel fully left and right, and
hold it there for five to ten seconds to find the cause
of the intermittent failure.
lf the problem recurs, the SRS indicator light will
stay on.

Problem recurs, light stays on.
6. lf you can't duplicate the intermiftent tailure, the sys-
tem is OK at this time.
