General Information - Repair Instruction1-93. Electronic Control Device
(1) Removal of the battery terminal cable
a. Before performing electrical servicing, disconnect the nega-
tive (-) cable from the battery in order to avoid short for burnout.
b. When disconnecting the terminal cable, turn off the ignition
and light switches, loosen the cable nut and raise the cable straight
up without twisting or prying it.
c. When disconnecting the terminal cable from the battery, all
information stored in the clock, radio and DTC shall be deleted,
therefore, these information shall be checked before disconnection.
(2) Processing of Electronic Parts
a. Do not open the cover or case of the ECU unless absolutely
necessary. (If the IC terminals are touched, the IC may be destroyed
by static electricity.)
b. To pull apart electrical connectors, pull on the connector itself,
not the wires.
c. Be careful not to drop electrical components, such as ECU
or relays. If they are dropped on a hard floor, they should be replaced
and not reused.
d. When steam cleaning an engine, protect the electronic
components, air filter and emission-related components from water.
e. Never use an impact wrench to remove or install tempera-
ture switches or temperature sensors.
f. When checking continuity at the wire connector, insert the
tester probe carefully to prevent terminals from bending.
4. Remove and Installation of Engine Intake Parts
(1) If any metal scrap is mixed in the inlet pass, that may give
a bad effect to the engine.
(2) When removing and installing of the inlet system parts, close (6) Airbag ECU
a. Never reuse the airbag ECU involved in a collision when the SRS has deployed.
b. The connectors to the airbag sensor assembly should be connected or disconnected with the airbag ECU
mounted on the floor. If the connectors are connected or disconnected while the airbag ECU is not mounted to
the floor, it could cause undesired inflation of the supplemental restraint system.
c. Work must be started after 60 seconds from the time the ignition switch is turned to the "LOCK" position
and the negative (-) terminal cable is disconnected from the battery, even if only loosing the set bolts of the
airbag ECU.
(7) Wire Harness and Connector
The SRS wire harness is integrated with the instrument panel wire harness assembly. All the connectors in
the system are a standard yellow color. If the SRS wire harness becomes disconnected or the connector becomes
broken due to an accident, etc., repair or replace it.Negative(-)

Chapter 3 Fuel SystemSection 1 Check Fuel System PressureOn-board inspection
1. Check the operation of the fuel pump.
(1) Connect the positive and the negative of the battery to
appropriate connector sockets of the fuel pump (see Figure 3-1).
Attention: Do not start the engine.
If there is pressure present, you will hear that the fuel is flowing.
If there is no pressure present, check the fusible cutout, fuse, EFI
open-circuit relay, fuel pump, ECM (Electronic Control Module) and
circuit joint.
(2) Turn the ignition switch to "OFF".
2. Check the pressure of the fuel.
(1) Check whether the battery voltage is more than 12V.
(2) Disconnect the negative wiring cable from the battery.
(3) Mount a pressure gauge on the fuel input pipe
(see Figure 3-2).
(4) Connect the negative terminal of the battery.
(5) Measure the fuel pressure.
Fuel oil pressure: 265-304kPa
If the pressure is low, check the fuel pipe and connection,
fuel pump, and fuel filter. If the pressure is too high,
replace the regulator.
(6) Start the engine. Measure the fuel pressure at idle speed. The
fuel pressure is 265-304KPa. If the pressure is unsatisfactory, checkFigure 3-1
Figure 3-3 Figure 3-2Fuel SystemCheck Fuel System Pressure3-15the fuel pump, pressure regulator, and injector, and replace if necessary.
(7) After shutting down the engine, check the fuel pressure and
keep the specified pressure for about 5 minutes. The fuel pressure is:
147KPa.
3. The fuel oil pressure regulator (DR) (see Figure 3-3).
Mounting position: On the distributing pipe for fuel.
Faults: Too low or too high fuel pressure, or hard to start.
General causes: Using poor fuel for a long time results in: 1.
strainer blocked; 2. serious leakage caused by particles and impurities.
Other reasons: Man-made mechanical damage, etc.
Maintenance precautions: During maintenance: 1. Never impact the diaphragm element with high pressure
gas; 2. Never clean it with aggressively corrosive liquid; 3. No distortion caused by external force.
Easy measuring method: For the system with oil return, connect a pressure gauge for the fuel on the suction
pipe, start the engine, and run at idle speed. Now, the fuel pressure in the engine should be about 260KPa; pull out
the vacuum pipe of the fuel pressure regulator, and the pressure should be 300KPa approximately.Battery

5-73Precautions:1. Don't operate refrigerant in confined space or near open fire.
2. Always wear eyeglass.
3. Be careful don't let liquid refrigerant contact your eyes and skin,
if liquid refrigerant contacts your eye or skin.
(a) Please wash with fresh water.
Warning:
Don't knead your eyes or scrub your skin
(b) Apply soft petroleum ointment on your skin.
(c) See doctor or go to hospital immediately for specialized
treatment.
4. Don't heat container or put it near open fire.
5. Be careful not to fall off, object should not touch container.
6. If there is no sufficient refrigerant in refrigerating system, don't
operate the compressor.
If there is no sufficient refrigerant in the system, insufficient oil
lubrication might cause burning out of compressor. Be careful to
avoid occurrence of such things.
7. When compressor runs, don't turn on pressure gauge high-pressure
valve.
If high-pressure valve is turned on, refrigerant will flow in reverse
direction, and cause bursting of refrigerant tank, so only low
pressure valve may be turned on or off.
8. Be careful to avoid excess refrigerant
Excess refrigerant will result in poor refrigerating capacity, worse
fuel economical efficiency, engine overheat etc problems.Symptom
