System Description

SUPPLEMENTAL RESTRAINT SYSTEMS: AIRBAG SYSTEM: SYSTEM DESCRIPTION

1. GENERAL

(a) Deceleration sensors used for the airbag system are installed on 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 based on the information from each sensor.

2. DEPLOYMENT CONDITION

(a) FRONTAL COLLISION





(1) 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 could be output with the deceleration sensor ON signal even without a signal from the front airbag sensors.

(2) Frontal collision signals are used to deploy the airbags and pretensioners in the illustration.

HINT
The occupant classification system restricts the deployment of the instrument panel passenger airbag assembly and front seat outer belt assembly RH Fail-Safe Chart.

(b) SIDE COLLISION (Pattern 1)





(1) Side collision (Pattern 1) signals are produced based on the information from the airbag ECU assembly, side airbag sensor assembly and door side airbag sensor.

(2) Side collision (Pattern 1) signals are used to deploy the airbags and pretensioners in the illustration.

(c) SIDE COLLISION (Pattern 2)





(1) Side collision (Pattern 2) signals are produced based on the information from the airbag ECU assembly and side No. 2 airbag sensor assembly.

(2) Side collision (Pattern 2) signals are used to deploy the airbags and pretensioners in the illustration.
