SUPPLEMENTARY RESTRAINT SYSTEM

DESCRIPTION AND OPERATION
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.
