16. BALL JOINT AND STEERING LINKAGE
SEALS (INSPECT FOR GREASE LEAKS AND
DAMAGE)
M1001003500322
1. These components, which are permanently lubricated at the
factory, do not require periodic lubrication. Damaged seals
and boots should be replaced to prevent leakage or grease
contamination.
2. Inspect the dust cover and boots for proper sealing, leakage
and damage, and replace them if defective.
17. DRIVE SHAFT BOOTS (INSPECT FOR
GREASE LEAKS AND DAMAGE)
M1001003600318
1. These components, which are permanently lubricated at the
factory, do not require periodic lubrication. Damaged seals
and boots should be replaced to prevent leakage or grease
contamination.
2. Inspect the dust cover and boots for proper sealing, leakage
and damage. Replace them if defective.

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
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.
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.
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
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.

SRS AIR BAG CONTROL UNIT (SRS-ECU)
The SRS may not activate if the SRS-ECU is not
installed properly, which could result in serious injury
or death to the vehicle's driver and front passenger.
1. Check the SRS-ECU case for dents, cracks, deformation or
rust.
2. Check the connector for damage, and check the terminals
for deformation or rust.
Replace the SRS-ECU if it fails the visual checks above
(Refer to GROUP 52B, SRS Air Bag Control Unit
P.52B-234).
AIR BAG MODULE, STEERING WHEEL AND
CLOCK SPRING
The removed air bag module should be stored in a
clean, dry place with the pad cover face up.
Replace any visually inspected part if it fails the
following inspection.
1. Remove the air bag module, steering wheel and clock
spring.
(Refer to GROUP 52B, Air Bag Module and Clock Spring
P.52B-237).
2. Check the pad cover for dents, cracks or deformation.

MAINTENANCE SERVICE

3. Check the connector for damage and deformed terminals,
and check the harness for binding.
4. Check the air bag inflator case for dents, cracks or
deformation.
5. Check the harness (built into the steering wheel) and
connectors for damage, and check the terminals for
deformation.
6. Check the clock spring connectors and protective tube for
damage, and terminals for deformities.
7. Visually check the case for damage.
If the clock spring's mating mark is not properly
aligned, the steering wheel may not completely rotate
during turn, or the flat cable within the clock spring
may be severed, obstructing normal operation of the
SRS and possibly lead to serious injury to the vehi-
cle's driver and front passenger.
8. Align the mating marks of the clock spring first. After turning
the front wheels to the straight-ahead position, install the
clock spring to the column.
Mating Marks Alignment;
After turning the clock spring fully clockwise, turn it
approximately 3 3/4 turns counterclockwise until the mating
marks are aligned.
9. Install the steering column covers, steering wheel and air
bag module (Refer to GROUP 52B, Air Bag Module and
Clock Spring P.52B-237).
10.Check the steering wheel for noise, binding or difficult
operation.

MAINTENANCE SERVICE
GENERAL00-55
The SRS may not activate if any of the above compo-
nents are not installed properly, which could result in
serious injury or death to the vehicle's driver and
front passenger.
11.Check the steering wheel for excessive free play.
Replace any part if it fails visual inspection (Refer to
GROUP 52B, Air Bag Module and Clock Spring P.52B-237).
FRONT SEATBACK ASSEMBLY WITH
SIDE-AIRBAG MODULE
If any improper part is found during the following
inspection, replace the front seatback assembly
with a new one.
Dispose of the old one according to the specified
procedure (Refer to GROUP 52B, Air Bag Module
Disposal Procedures P.52B-254).
Never attempt to measure the circuit resistance of
the air bag module (squib) even if you are using
the specified tester. If the circuit resistance is mea-
sured with a tester, accidental air bag deployment
will result in serious personal injury.
1. Check the air bag module deployment section for dents or
deformation.
2. Check the connector for damage; Check the terminals for
deformation; and check the harness for binding.
Replace the front seat if it fails the visual checks above
(Refer to GROUP 52A, Front Seat P.52A-33).
SEAT BELT WITH PRE-TENSIONER
If the seat belt pre-tensioner is not installed
securely and correctly, the seat belt pre-tensioner
may not operate normally.
If a dent, crack, deformation or rust is detected,
replace with a new seat belt pre-tensioner.
1. Check the seat belt pre-tensioner for dents or deformation.
2. Check that the seat belt pre-tensioner is installed correctly to
the vehicle body.
Replace the seat belt pre-tensioner if it fails the visual
checks above (Refer to GROUP 52B, Seat Belt
Pre-tensioner P.52B-250).

WIRING HARNESS
1. Check the connector for poor connection.
The SRS system may not operate if SRS harnesses or
connectors are damaged or improperly connected,
which could result in serious injury or death to the
vehicle's driver and front passenger.
2. Check the harness for binds, the connectors for damage,
and the terminals for deformation. Replace any connector or
harness that fails the visual inspection (Refer to GROUP
52B, SRS Precaution P.52B-16).
