47Section 5 Fuel Emission Control System1. Check the operation when the fuel is cut off.
(a) Warm up the engine for at least 2500rpm. Using sound grade meter, check injector's noise when running.
See (Figure 105).
(b) The noise from the injector should stop immediately after loosing the throttle. Repeat for several times.
2. Check fuel vapor emission control system. See (Figure 106)
(a) Disconnect vacuum pipe after starting the engine.
(b) Select "ACTIVE TEST" and "PURGE VSV (Vacuum Solenoid Valve)" from the display on the fault
diagnosis tester. Confirm vacuum at VSV port.
(c) Connect the vacuum pipe after completing "ACTIVE TEST".
(d) After conducting "ECM DATA MONITOR"on the fault diagnosis tester, select "PURGE VSV" to
check operation.
(e) Start the vehicle after warming up the engine to confirm the VSV status is changed from disconnected to
connected. See (Figure 107).
3. Check the fill fuel port cap and gasket for distortion or damage. See (Figure 108)

102(7) Install front wheel, wheel nut torque: 95~115N.m
(8) Make sure that the propeller shafts for 1.3L engine and 1.5L engine are not interchanged
at the time of replacement
(9) Check the ABS sensor signal, check and adjust the front wheel alignment if necessary.

143Section 4 Vacuum Booster with Brake Master Cylinder AssemblyNotice: The vacuum booster with brake master cylinder assembly must be repaired by
manufacturer. Replace it if it is faulty.On-vehicle inspection1. Check vacuum booster
(a) Air tightness check
(1) start the engine, run 1 or 2 minutes then shut off. Depress the brake pedal several times slightly.
Hint: if the pedal rises gradually after depressing the pedal, the booster is airtight.
(2) Depress the brake pedal while the engine is running, and stop the engine with the pedal depressed.
Hint: if there is no change in the pedal reserve stroke after holding the pedal for 30 seconds,
the booster is air--tight.
(b) Operating check
Depress the brake pedal and start the engine. If the pedal goes down slightly, operation is normal.
2. Check the vacuum check valve
(1) Remove the connecting pipe with the check valve
(2) Check the direction from the booster to the engine. Check valve for ventilation. It should not
ventilate in the reverse order.
(3) Replace it if it is faulty.
Notice: Pay attention to the matchmark on the connecting hose when connecting
the hose with vacuum check valve. Do not install it in reverse order.Replacement1. Remove the brake pipe on the brake master cylinder (master cylinder)
2. Refer to Brake Pedal Replacement for other operation
Notice:
(1) The torque of the union thread on the brake master cylinder (master cylinder )
and brake pipe: 12-16 N.m
(2) Bleed all the air in the brake system after installationGoodPoorThird

6Confirm symptomV. SYMPTOM SIMULATIONNOTES:
The most difficult conditions to handle in the fault troubleshooting are that the fault symptom dose not appear.
Under the circumstances, make sure first to make a comprehensive analysis to the fault described by the
customer, then to simulate an environment that is similar or the same with the conditions when the fault of the
customer's vehicle occurred. No matter how rich the experience of the technician is and how skillful he is, if
he make a fault troubleshooting analysis without confirm the fault symptom, it is inevitable for him to neglect
some important factors and incorrectly guess, which may cause barriers to repair. For example, if a fault
occurs only when the engine is cool or if a fault occurs only caused by a vibration from pavement and so on,
when the engine is checked in the hot or static state, it is no way to confirm. Because of vibration, high-
temperature or seeping water (Vapor) often causes some faults that are difficult to reappear. So, here are
some effective symptom simulation tests.
KEY POINTS OF SYMPTOM SIMULATION TEST:
In the symptom simulation test, no doubt it is important to confirm the fault symptom, but the fault position or
fault components must be also found out. So, before the test and the pre-inspection of connection, narrow the
range of the circuit where faults may occur according to the fault symptom. Then make a symptom simula-
tion test to see if the circuit measured is normal; the fault symptom is also verified at the same time.
1. Way of Vibration: When vibration may be the major cause of the fault.
For example:
(a) Use your hand to gently vibrate the sensor that is considered the cause of the fault, in order to check if it
is ineffective.
(b) Softly rock the connector and harness in horizontal and vertical direction.
Notes: Hard rock may cause the relay circuit open.
2. Way of Spraying Water: When rainy weather or wet environment may be the major cause of the fault.
(a) Spray water on the vehicle to check if the fault occurs.
NOTES:
yBe sure not to directly spray water into the engine compartment. Spray the water on the face of the
radiator to change the temperature and humidity indirectly.
yBe sure not to spray water onto electronic devices and controllers.

383Section 5 Painting Technique after Body RepairPartial painting is needed when the vehicle crashes, parts rust, surface bubbles and color changes. The
painting techniques after repair are as follows:I. Base Treatment (Pre-Treatment)1. Peel the layer of painting and the coating on the panel.
2. Remove the edges and corners and polish the steel surface where painting peeled and the paint film at the
edges.
3. Cleaning and degrease. Clear up the dust and dirt and remove the oil, etc with degreaser.II. Base Coating Procedure1. Apply primer. Apple air drying type paint on the metal surface.
2. Air dry or heat dry (infrared drier) the primer.
3. Apply putty. Apply air drying type oil-base putty and Polyester-base putty on the panel surface that needs
repairing.
4. Air dry or heat dry the putty.
5.Manually polish the putty to make it smooth.
6. Manually polish with water to clear up tracks caused by sand paper.
7. Clear up the dust and the greasy dirt, and dry the putty polishing liquid.
8. Clean the greasy dirt on the polishing surface.
9. Use shield cover or paper to keep out the area that need not repairing.III.Intermediate Coating Painting1. Paint the second primer.
2. Air dry or heat dry.
3. Apply putty, and let it dry. Then look for sandhole or sand paper tracks.
4. Manually polish with water.
5. Clean it and let it dry by air. (The times of applying putty and polishing depends on the smoothness of the
surface)IV. Preparation For Applying Final Paint1. Shielding. Shield the area that needs not painting with paper.
2. Clear up the dust and degrease. Clear up the dust and oil on the painting surface.
3. Toning. Mix paints to get the color the same with the final paint.
4. Mixing paints.
