AIRBAG SYSTEM SYSTEM DESCRIPTION


  1. GENERAL


    1. 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.

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

  2. DEPLOYMENT CONDITION


    1. FRONTAL COLLISION

      A0041JWE15

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

        Tech Tips

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

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

    2. SIDE COLLISION (Pattern 1)

      A0042TRE12

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

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

    3. SIDE COLLISION (Pattern 2)

      A0043OXE05

      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 airbag in the illustration.
