SRS AIRBAG SYSTEM


  1. AIRBAG SENSOR ASSEMBLY


    1. When the airbag system reaches a decision to deploy the airbags based on the signals detected by the front airbag sensors and the airbag sensor assembly, it deploys the driver and front passenger dual-stage SRS airbags, driver knee airbag, front passenger knee airbag, and seat belt pretensioners. When the airbag system reaches a decision to deploy the airbags based on the signals detected by the side airbag sensors, rear airbag sensors, rear floor side airbag sensor, and airbag sensor assembly, it deploys the SRS front side airbags, rear side airbags, and curtain shield airbags. Furthermore, it is equipped with a diagnosis function to perform self-diagnose system malfunctions.

    2. The airbag sensor assembly has 4 built-in sensors: Deceleration sensor 1 detects vehicle deceleration in the lateral direction in addition to the longitudinal direction, deceleration sensor 2 detects deceleration in the longitudinal direction, and the 2 roll rate sensors detect angular velocity in the roll direction.

    3. Each signal is transmitted as follows:

      Target ECU Signal Communication Path
      ECM Collision Detection Signal CAN Communication Circuit
      Main Body ECU (Multiplex Network Body ECU) Forced Door Unlock Signal Direct Circuit
      Combination Meter Assembly

      • Front Seat Belt Buckle Switch (for Driver) ON Request Signal

      • SRS Warning Light ON Demand Signal
