| Pre-crash seat belt control unit (driver side) |
- Integrated front seat belt pre-tensioner, control unit and seat belt motor.
- Controls pre-crash seat belt control unit (passenger side) as slave control unit.
- Seat belt motor operates when belt is extended and retracted.
|
| Pre-crash seat belt control unit (passenger side) |
- Integrated front seat belt pre-tensioner, control unit and seat belt motor.
- Is controlled by pre-crash seat belt control unit (driver side) as master control unit.
- Seat belt motor operates when belt is extended and retracted.
|
| Brake pedal stroke sensor |
- Varies voltage based on brake pedal position and sends the signal to pre-crash seat belt control unit (driver side).
- There are 2 signals sent from the brake pedal stroke sensor (brake pedal stroke sensor signal 1 and 2).
- Pre-crash seat belt control unit (driver side) judges the stroke distance and speed of the brake pedal based on the voltage signals sent by each side of the sensor.
