18. SUSPENSION SYSTEM (INSPECT FOR
LOOSENESS AND DAMAGE)

M1001009600048

Visually inspect the front/rear suspension components for dete-
rioration and damage. Re-tighten the front/rear suspension
components retaining bolts to specified torque.

19. SRS AIR BAG (INSPECT FOR SRS SYSTEM)

M1001003700326

The entire SRS including air bag and pre-tensioner seat belt
must be inspected by an authorized MITSUBISHI MOTORS
dealer 10 years.

SRS WARNING LIGHT CHECK

Turn the ignition key to the "ON" position. Does the

"SRS" warning light illuminate for several seconds, and then go
out? If yes, the SRS system is functioning properly. If no, refer
to GROUP 52B, Diagnosis

P.52B-215

.

SRS COMPONENT VISUAL CHECK

DANGER

Wait at least 60 seconds after disconnecting the bat-
tery cable before doing any further work. The SRS
system is designed to retain enough voltage to
deploy the air bag for a short time even after the bat-
tery has been disconnected. Serious injury may result
from unintended air bag deployment if work is done
on the SRS system immediately after the battery
cable is disconnected.

WARNING

Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER
HANDLING.

1. Turn the ignition switch to the "LOCK" (OFF) position,

disconnect the negative battery cable and tape the terminal.

2. Remove the floor console assembly (Refer to GROUP 52A,

Floor Console

P.52A-10

).

3. Disconnect a connector from the SRS-ECU.

FRONT IMPACT SENSORS

1. Check that the arrows on the sensors face toward the front

of the vehicle.

WARNING

•

The SRS may not activate if a front impact sensor
is not installed properly, which could result in seri-
ous injury or death to the vehicle's driver and pas-
senger.

•

If a dent, crack, deformation or rust is detected,
replace with a new sensor.

2. Check the front side member and front impact sensor for

deformation or rust.

3. Check the front impact sensor wiring harness for binding;

Check the connector for damage; and check the terminals
for deformation.
Replace the sensor and/or wiring harness if they fail the
visual check (Refer to GROUP 52B, SRS Service
Precautions

P.52B-16

and GROUP 52B, Front Impact

Sensor

P.52B-231

).

SIDE IMPACT SENSORS

WARNING

•

If the side impact sensor is not installed securely
and correctly, the side-air bag may not operate
normally.

•

If a dent, crack, deformation or rust is detected,
replace with a new sensor.

1. Check the side impact sensor and bracket for dents, cracks

or deformation. The side impact sensors are located inside
the center pillars (LH/RH).

2. Check the connector for damage, and terminal for

deformation.

3. Check that there is no bending or corrosion in the center

pillars (LH/RH).
Replace the side impact sensor if it fails the visual check
(Refer to GROUP 52B, Side Impact Sensor

P.52B-247

).

NOTE: The illustration shows the left side impact sensor (RH).
The position of the other side impact sensor (LH) is symmetri-
cal to this.
