SUPPLEMENTAL RESTRAINT SYSTEMS  AIRBAG SYSTEM  SYSTEM DESCRIPTION  


GENERAL


a.

Deceleration sensors used for the airbag system are installed to various parts on the vehicle and calculate the deceleration rate of each part during a collision.


b.

Depending on the situation, the airbag ECU assembly sends a deployment signal to each airbag and pretensioner based on the information from each sensor.

i.

Frontal collision signals are produced based on the information from the airbag ECU assembly and front airbag sensors.

HINT:

In case of a frontal collision, the SRS ignition signal may be output after receiving an ON signal from the deceleration sensor built into the airbag ECU assembly even without a signal from the front airbag sensors.



ii.

Frontal collision signals are used to deploy the airbag and pretensioner in the illustration.
