Supplemental Restraint System (SRS)
Description, Operation and Location
The airbag/Supplemental Restraint system (SRS) includes the driver's and passenger's airbags. This systems also includes
the Emergency Tension Restraint (ETR) seat belts.
The driver' airbag is located beneath the steering wheel pad and inflates in 25 milliseconds. The passenger's airbag is
located inside the upper right hand side of the instrument panel. The folded airbag and tubular gas generator are located
inside a plastic housing. The airbag is made of nylon material with gas permeable sides.
If voltage is interrupted during a collision, the driver's and passenger's airbags will deploy within 100 milliseconds, but the
ETR will not deploy. If vehicle voltage drops below 9.5V for longer than 10 seconds, the airbag system warning lamp will
light. Once the voltage is greater than 10 volts, the lamp will go off.
The SRS control module (N2/2) is located on the transmission tunnel. This module process vehicle deceleration from an frontal
impact. An arming switch is installed to interrupt the deployment circuit during normal driving mode. This allows for system
deployment only when the limits have been exceeded.
The control module detects longitudinal vehicle deceleration and generates a signal that is processed and sent to the
threshold evaluation switch. When the limit is exceeded, information is given to the ETR and SRS for proper deployment
sequence.
