SRS System Description

The supplementary restraint system (SRS) provides enhanced passive protection for the driver and front passenger in the event of a serious collision. The protection afforded is above that which would normally be provided using standard restraint systems (seat belts). The system is regarded as passive in the respect that it operates automatically without pre-conditional interactions by the vehicle occupants.

The distributed SRS system consists of the following components:
- SRS diagnostic and control unit (DCU)
- Front crash sensors (distributed systems only)
- Driver airbag module
- Passenger airbag module
- Side airbag modules (2 off - driver and front passenger) - from 99MY onwards
- Seat belt pre-tensioners (2 off - driver and front passenger) - from 99MY onwards
- Rotary coupler
- SRS warning lamps

Interconnecting wiring for the system is contained in distinctive yellow sleeving and integrated into the vehicle harness.

An ISO 9141 K-line (bi-directional) serial communication link connects the SRS DCU to the vehicle's diagnostic socket.
