Supplemental Restraint System - Mitsubishi Pajero Pinin 1999 Workshop Manual

GENERAL ±
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
To improve safety, the SRS is available as optional
parts. This system enhances collision safety by
restraining the front occupants in case of an
accident.
The SRS consists of four air bag modules, SRS
air bag control unit (SRS-ECU), front impact sensor,
side impact sensors, seat belt pre-tensioner, SRS
warning lamp and clock spring. The air bags are
located in the centre of the steering wheel, above
the glove box, and built into the front seat back
assemblies. Each air bag has a folded air bag and
an inflator unit. The SRS-ECU under the floor
console monitors the system and has a safing
G-sensor and an analog G-sensor. The front impact
sensor are installed on the front side mrmber. The
side impact sensors inside the quater panel inner

or the quarter panels, inner monitor any shocks
coming from the side of the vehicle. The warning
lamp on the instrument panel indicates the
operational status of the SRS. The clock spring
is installed in the steering column.
The SRS side air bags deploy if an impact received
at the side of the vehicle is stronger than a certain
set value, in order to protect the front seat occupant's
torso in the event of a collision. Only authorized
service personnel should do work on or around the
SRS components. Those service personnel should
read this manual carefully before starting any such
work. Extreme care must be used when servicing
the SRS to avoid injury to the service personnel
(by inadvertent deployment of the air bags) or the
driver (by rendering the SRS inoperative).
