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.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.

EGR SYSTEM CHECKM1173002600348
1. Disconnect the vacuum hose (Green stripe) from
the EGR valve, and then connect a hand vacuum
pump via the three-way terminal.
2. When the engine is hot or cold, check the
condition of vacuum by racing the engine.
When engine is cold
(Engine coolant temperature: 20°C or less)
When engine is hot
(Engine coolant temperature: 80°C or higher)
3. Disconnect the three-way terminal.4. Connect the hand vacuum pump to the EGR
valve nipple.
5. Check whether the engine stalls or the idling is
unstable when a vacuum of 30 kPa or higher is
applied during idling.
EGR VALVE CHECKM1173002800223
1. Remove the EGR valve and inspect for sticking,
carbon deposits, etc. If found, clean with a
suitable solvent so that the valve seats correctly.
2. Connect a hand vacuum pump to the EGR valve.
3. Apply 67 kPa of vacuum, and check that the
vacuum is maintained.
4. Apply a vacuum and check the passage of air by
blowing through one side of the EGR passage. Throttle valve Normal vacuum condition

same as barometric pressure.)

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.

ON-VEHICLE SERVICE
POWER STEERING37-14
CAUTION
Perform air bleeding only while cranking the
engine. If air bleeding is performed while the
engine is running, air could enter the fluid.
During air bleeding, refill the steering fluid
supply so that the level never falls below the
"MIN" mark on the oil reservoir.
3. Turn the steering wheel all the way to the left and
right five or six times while using the starter motor
to crank the engine intermittently several times
(for 15 to 20 seconds).
4. Connect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38 or P.16-39).
5. Start the engine (idling).
6. Turn the steering wheel to the left and right until
there are no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the
level is between "MAX" and "MIN" marks.
8. Confirm that there is very little change in the fluid
level when the steering wheel is turned left and
right.
CAUTION
If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled. If
air bleeding is not complete, there will be
abnormal noises from the pump and the
flow-control valve, and this condition could
cause reduce the life of the power steering
components.
9. Confirm that the change in the fluid level is no
more than 5 mm when the engine is stopped and
when it is running.
10.If the change of the fluid level is 5 mm or more,
the air has not been completely bled from the
system. The air bleeding procedure must be
repeated.
OIL PUMP PRESSURE TESTM1372002300315
1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•MB990662: Power Steering Oil Pressure Gauge
•MB991548: Power Steering Oil Pressure Gauge
Adapter (pump side)
•MB991549: Power Steering Oil Pressure Gauge
Adapter (hose side)
2. Bleed air, then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50
− 60°C.
3. Start the engine and idle it at 1000 ± 100 r/min.
CAUTION
The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.
4. Fully close the shut-off valve of the pressure
gauge and measure the oil pump relief pressure
to confirm that it is within the standard value
range. Open it again immediately after checking
the pressure.
Standard value: 8.8 − 9.5 MPa
5. If it is not within the standard value, replace the oil
pump.
6. Check whether or not the hydraulic pressure is
the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa

DOOR WINDOW GLASS ADJUSTMENTM1423001000327
Check that the door glass moves while contacting
the door glass channel when it is raised and lowered
fully. If not, adjust the door window according to the
following procedures.
1. Remove the door trim assembly (Refer to GROUP
52A, Door trim P.52A-15).
2. Remove the waterproof film (Refer to P.42-39).
3. Loosen the door glass mounting screw via the
adjusting hole with the door window glass fully
closed, then lower the window glass a little.
4. Fully close the door window glass again and
tighten the door glass mounting screw firmly via
the adjusting hole.
GLASS SLIDING MECHANISM CHECK
AND ADJUSTMENT
M1429000900091
If the window glass automatically starts moving
downwards at the wrong time while it is being raised,
carry out the following adjustment or replacement
procedures.
1. Remove the door trim assembly (Refer to GROUP
52A, Door trim P.52A-15).
2. Remove the waterproof film (Refer to P.42-39).
3. Remove the window regulator assembly from the
door window glass, and then raise and lower the
door window glass by hand to check the operation
force.
NOTE: Insert a cushion or similar object to
prevent damage to the glass if it should happen to
fall down.4. If the door window glass does not move up and
down smoothly, check or repair the following
points.
•Check the installation condition of the
runchannel.
•Repair any twisting in the door sash.
•Check the installation condition of the lower sash
or the centre sash.
NOTE: The lower sash cannot normally be
adjusted, but it may be possible to adjust the sash
span slightly within the range allowed by
manufacturing tolerances by pushing the lower
sash outwards while re-installing it.
5. If repair or adjustment is not possible, replace the
door assembly.
POWER WINDOW OPERATING CURRENT
CHECK
M1429001100184
1. Remove the power window fuse and connect an
ammeter as shown in the illustration.
2. When the power window switch is pressed to the
“UP” position, a large amount of current flows at
the time the window starts to close and when it is
fully closed, so measure the operation current in
the interval between these two points.
