EFISYSTEM
PRECAUTION
1. The engine control system has self diagnosis function. The ECU memorizes all malfunction codes 'Nhich
have occurred in the past and/or are occurring at present.
The memorized malfunction codes are erased when the battery ground cable is disconnected from the
battery terminal. Hence, prior to starting any repairs, be sure to check to see if any malfunction code has
been memorized.
2. When performing operations on the fuel system or its related operation, never smoke and keep away any
fire.
3. Before disconnecting the fuel line, be sure to disconnect the battery ground cable from the negative
terminal of the battery.
4. The fuel line is pressurized to a pressure about 250.1 kPa (2.55 kgf/cm') higher than the pressure inside
the surge tank. Therefore, when disconnecting the fuel line, be sure to loose the fuel line slowly and
prevent the fuel from splashing with a cloth or the like.
5. Do not allow gasoline to get to any parts made of rubber, leather and resin and/or to the electric parts.
6. When cleaning the engine compartment with water, make sure that no water gets
to the
electrical system.
7. Ensure that the battery voltage should be 11 volts or more, before performing the inspection.
INSPECTION PRECAUTIONS
Maintenance precautions
1. Ensure that the engine is correctly tuned up.
2. Precautions during gauge connection
(1) To connect the tachometer, connect the following SST
between the distributor connector and the distributor
connector of the engine wire.
SST: 09991-87703-000
(2) Connect the measuring terminal of the tachometer to the
measuring terminal of the SST.
NOTE:
• This does not apply if your tachometer is a pick-up type.
(3) Use the battery as power source for a timing light,
tachometer and so forth.
(4) Never allow the tachometer terminal to touch the
ground, for it could result in damage to the ignitor and/or
ignition coil.
(5) Some kinds of tachometers may not be suited for the
ignition system of the vehicle. Therefore, ensure that
your tachometer is compatible with the ignition system
of the vehicle.
