Main Component Parts and Functions

Spiral Cable

• Spiral cable electrically connects air bag diagnosis sensor unit and driver air bag module. Spiral cable mainly consists of the rotating portion which performs the same movement as steering wheel, the fixed case which is installed on steering wheel, and the cable which connects the rotating portion.

  

• Spiral cable is built into steering angle sensor which is installed to a space between combination switch and steering wheel.

Crash Zone Sensor

• Crush zone sensor is installed to radiator core support via bracket . Crash zone sensor integrates frontal collision “G” sensor which detects frontal collision impact that exceeds the specified limit of the Nissan Ariya vehicle.

  

  : Nissan Ariya Vehicle front

• In a frontal collision that exceeds the specified limit of the Nissan Ariya vehicle, crush zone sensor detects impact. If frontal collision safing sensor in air bag diagnosis sensor unit judges that impact is due to a collision, driver air bag, passenger air bag, seat belt pre-tensioner (front and second) and lap pre-tensioner operate.

Satellite Sensor

• Front door satellite sensor is installed to front door panel.

  

  : Nissan Ariya Vehicle front

• C-pillar satellite sensor is installed to luggage side lower finisher remove portion of the C-pillar.

• Front door satellite sensor is equipped with side collision pressure sensor which detects side collision impact that exceeds the specified limit of the Nissan Ariya vehicle.

• C-pillar satellite sensor are equipped with side collision G sensor which detects side collision impact that exceeds the specified limit of the Nissan Ariya vehicle.

• In a side collision that exceeds the specified limit of the vehicle, satellite sensor detects impact. If side collision safing sensor in air bag diagnosis sensor unit judges that impact is due to a collision, front side air bag, front center air bag (with front center air bag models), rear side air bag, curtain air bag, seat belt pre-tensioner and lap pre-tensioner operate.

Air Bag Diagnosis Sensor Unit

• Air bag diagnosis sensor unit is installed to front seat center portion (under center console). Air bag diagnosis sensor unit integrates control functions of driver air bag, passenger air bag, front side air bag, front center air bag　(with front center air bag models), rear side air bag, curtain air bag, seat belt pre-tensioner and lap pre-tensioner.

  

  : Nissan Ariya Vehicle front

• Air bag diagnosis sensor unit integrates frontal collision G sensor, frontal collision safing sensor, and side collision safing sensor.

• Air bag diagnosis sensor unit has a function that judges impact due to frontal and side collisions exceeding the specified limit of the Nissan Ariya vehicle. Air bag diagnosis sensor unit also has an auxiliary power supply function that supplements battery power supply in the event battery is damaged in a collision.

• Air bag diagnosis sensor unit diagnoses electric system of entire air bag system. Self-diagnosis function is adopted, which indicates system malfunction by turning ON air bag warning lamp on combination meter when a malfunction is detected. Diagnosis using CONSULT is possible.

Air Bag Warning Lamp

• Air bag warning lamp turns ON or blinks indicating a system malfunction when a malfunction is detected for electric system of SRS air bag system and seat belt pre-tensioner system.

  

• For operation check purposes, air bag warning lamp turns ON for 7 seconds after power switch is turned ON. During this period of time, air bag diagnosis sensor unit performs system diagnosis.

  NOTE:

  SRS air bag and seat belt pre-tensioner do not operate for approximately 7 seconds (air bag warning lamp is turning ON) after power switch is turned ON.

Occupant Detection System Sensor

• Occupant detection system sensor installed in the passenger seat track portion of the frame.

• Occupant detection system sensor transmits the passenger seat status (occupied or empty) to occupant detection system control unit.

Occupant Detection System Control Unit

• Occupant detection system control unit installed under the passenger seat cushion frame.

• Occupant detection system control unit transmits the passenger seat status (occupied or empty) to air bag diagnosis sensor unit.

Front Passenger Air Bag OFF Indicator
