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.
