Mitsubishi Montero Sport (2004+). Manual — part 733

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).

The Supplemental Restraint System (SRS) and seat
belt with pre-tensioner is designed to supplement the
driver's and front passenger's seat belts to help
reduce the risk or severity of injury to the driver and
front passenger by activating and deploying both
front air bags in certain frontal collisions.
The SRS consist of four air bag modules, SRS air
bag control unit (SRS-ECU), front impact sensors,
SRS warning light, and clock spring. Air bags are
located in the center of the steering wheel, above the
glove box. Each air bag is made up of a folded air
bag and an inflator unit. The control unit under the

floor console monitors the system and has a safing
G-sensor and an analog G-sensor. The front impact
sensors are installed in the fender shield panel. The
warning light on the instrument panel indicates the
operational status of the SRS. The clock spring is
installed in the steering column. The seat belt
pre-tensioner is built into the driver's front seat belt
retractor. 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.

ON-BOARD DIAGNOSTIC/SRS WARNING LIGHT
FUNCTION
The diagnosis unit monitors the SRS system and stores data
concerning any detected faults in the system. When the ignition
key is in "ON" or "START" position, the SRS warning light
should illuminate for about 7 seconds and then turn "OFF." That
indicates that the SRS system is in operational order. If the
SRS warning light does any of the following, immediate inspec-
tion by an authorized dealer is needed.
1. The SRS warning light does not illuminate as described

above.

2. The SRS warning light stays on for more than 7 seconds.
3. The SRS warning light illuminates while driving.
If a vehicle's SRS warning light is in any of these three condi-
tions when brought in for inspection, the SRS system must be
inspected, diagnosed and serviced in accordance with this
manual.
