WARNINGS REGARDING SERVICING OF SUPPLEMENTAL
RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
(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) The SRS components and seat belt with pretensioner should not be subjected to heat, so
remove the SRS-ECU, driverís and front passengerís air bag modules, clock spring, side air bag
modules, and seat belt -pre-tensioner before drying or baking the vehicle after painting.
ï SRS-ECU, air bag module and clock spring 93°C or more
ï Seat belt with pre-tensioner: 90°C or more
(3) Service or maintenance of any SRS component or SRS-related component must be performed
only at an authorized MITSUBISHI dealer.
(4) 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.

CRANKCASE EMISSION CONTROL
SYSTEM
GENERAL INFORMATION (CRANKCASE
EMISSION CONTROL SYSTEM)
M1173005000237
The crankcase emission control system prevents
blow-by gases from escaping inside the crankcase
into the atmosphere.
Fresh air is sent from the air cleaner into the
crankcase through the breather hose.
The air becomes mixed with the blow-by gases
inside the crankcase.
The blow-by gas inside the crankcase is drawn into
the intake manifold through the positive crankcase
ventilation (PCV) valve.
The PCV valve lifts the plunger according to the
intake manifold vacuum so as to regulate the flow of
blow-by gas properly.
In other words, the blow-by gas flow is regulated
during low load engine operation to maintain engine
stability, while the flow is increased during high load
operation to improve the ventilation performance.

replace it.
AD
GENERAL INFORMATION (EVAPORATIVE
EMISSION CONTROL SYSTEM)
M1173005100405
The evaporative emission control system prevents
fuel vapours generated in the fuel tank from escaping
into the atmosphere.
Fuel vapours from the fuel tank flow through the fuel
tank pressure control valve and vapour pipe/hose to
be stored temporarily in the canister.
When driving the vehicle, fuel vapours stored in the
canister flow through the purge solenoid and purge
port and go into the intake manifold to be sent to the
combustion chamber.
When the engine coolant temperature is low or when
the intake air quantity is small (when the engine is at
idle, for example), the engine control unit turns the
purge solenoid off to shut off the fuel vapour flow to
the intake manifold.
This does not only insure the driveability when the
engine is cold or running under low load but also
stabilize the emission level.

EXHAUST GAS RECIRCULATION
(EGR) SYSTEM
GENERAL INFORMATION (EGR SYSTEM)
M1173005200327
The exhaust gas recirculation (EGR) system lowers
the nitrogen oxide (NOx) emission level.
When the air/fuel mixture combustion temperature is
high, a large quantity of nitrogen oxides (NOx) is
generated in the combustion chamber.
Therefore, this system recirculates part of emission
gas from the exhaust port of the cylinder head to the
combustion chamber through the intake manifold to
decrease the air/fuel mixture combustion
temperature, resulting in reduction of NOx.
SYSTEM DIAGRAM
<4G1>
The EGR flow rate is controlled by the EGR valve so
as not to decrease the driveability.
OPERATION
The EGR valve is being closed and does not
recirculate exhaust gases under one of the following
conditions.
Otherwise, the EGR valve is opened and recirculates
exhaust gases.
• The engine coolant temperature is low.
• The engine is at idle.
• The throttle valve is widely opened.

5. If no negative pressure is generated, the port is
probably blocked and should be cleaned.

GENERAL INFORMATION
GENERAL INFORMATION
The engine mounting system employs the inertial
axis four-point suspension method, which is field
proven.
• The optimised locations of the front and rear roll
mounts well distribute their loads thereby
reducing engine idling vibrations.

CAUTION
• Before removing the steering wheel and air bag module assembly, always refer to GROUP 52B Service Precautions P.52B-5, Air bag Module and Clock Spring P.52B-210. 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 air bag to be inoperative and serious
injury.
