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).
