GENERAL -Precautions Before Service00-5
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS), SEAT BELT WITH PRE-TENSIONER
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B - Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
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.
(3) Warning labels must be heeded when servicing or handling SRS components and seat belt with
pre-tensioner. Warning labels are located in the following locations.
DHood
DSun visor
DGlove box
DSRS-ECU
DSteering wheel
DSteering gearbox
DAir bag module (driver’s side and front passenger’s side)
DFront impact sensor
DClock spring
DSeat belt with pre-tensioner
DSide air bag module
DSide impact sensor
(4) Always use the designated special tools and test equipment.
(5) Store components removed from the SRS and seat belt with pre-tensioner in a clean and dry
place.
The air bag module and seat belt with pre-tensioner should be stored on a flat surface and
placed so that the pad surface is facing upward.
Do not place anything on top of it.
(6) Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module, clock
spring and side impact sensor) and seat belt with pre-tensioner.
(7) Whenever you finish servicing the SRS and seat belt with pre-tensioner, check the SRS warning
lamp operation to make sure that the system functions properly.
(8) Be sure to deploy the air bag and seat belt with pre-tensioner before disposing of the air bag
module and seat belt with pre-tensioner or disposing of a vehicle equipped with an air bag and
seat belt with pre-tensioner. (Refer to GROUP 52B - Air Bag Module and Seat Belt with Pre-tensioner
Disposal Procedures.)
2. Observe the following when carrying out operations on places where SRS components and seat
belt with pre-tensioner are installed, including operations not directly related to the SRS air bag and
seat belt with pre-tensioner.
(1) When removing or installing parts do not allow any impact or shock to the SRS components
and seat belt with pre-tensioner.
(2) SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove
the SRS components and seat belt with pre-tensioner before drying or baking the vehicle after
painting.
DSRS-ECU, air bag module, clock spring, front and side impact sensors: 93_C or more
DSeat belt with pre-tensioner: 90_C or more
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

REMOVAL AND INSTALLATION
Caution
1. Before removing the steering wheel and airbag module assembly, always refer to GROUP 52B
- Service Precautions, Airbag Module and Clock Spring. Also, set the front wheels so that
they are facing straight forward, and remove the ignition key. If you fail to do this, the SRS
clock spring will be damaged, causing the SRS airbag to be inoperative and serious injury.
2. *: Indicates parts which should be initially tightened, and then fully tightened after placing
the vehicle horizontally and loading the full weight of the engine on the vehicle body.

ABS <4WD> -General Information35B-2
GENERAL INFORMATION
ABS has been adopted as standard equipment
in all vehicles to maintain directional stability and
steering performance during sudden braking.
The ABS control method used is a 4-sensor,
4-channel method (previous models: 4-sensor,
3- channel method
)which allows the brake
pressures for all four wheels to be controlled
independently of each other. The system has the
following features.
DEBD
*(Electronic Brake force Distribution
system) control has been added to provide the
ideal braking force for the rear wheels.DThe hydraulic unit function has been integrated
with the hydraulic brake booster (HBB).
DSelect solenoid valves (two valves for FL and
FR) have been adopted in order to reduce the
pedal kickback and improve the operation
feeling when the ABS is operating.
DIndependent 4-wheel control is carried out wile
the vehicle is turning in order to increase the
braking force.
NOTE
*EBD: Electronic Brake-force Distribution
EBD CONTROL
In ABS, electronic control method is used whereby
the rear wheel brake hydraulic pressure during
braking is regulated by rear wheel control solenoid
valves in accordance with the vehicle’s rate of
deceleration and the front and rear wheel slippage
which are calculated from the signals received from
the various wheel sensors. EBD control is a control
system which provides a high level of control for
both vehicle braking force and vehicle stability. The
system has the following features.
DBecause the system provides the optimum rear
wheel braking force regardless of the vehicle
laden condition and the condition of the road
surface, the system reduces the required pedal
depression force, particularly when the vehicle
is heavily laden or driving on road surfaces
with high frictional coefficients.DBecause the duty placed on the front brakes
has been reduced, the increases in pad
temperature can be controlled during front
brakes applying to improve the wear resistance
characteristics of the pad.
DControl valves such as the proportioning valve
are no longer required.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring and interconnecting
wiring. Other SRS-related components (that mayhave to be removed/installed in connectionwith SRS service or maintenance) are
indicated in the table of contents by an asterisk(*).
