General PrecautionsINFOID:0000000012431266
•
Always use a 12 volt battery as power source.
• Do not attempt to disconnect battery cables while engine is
running.
• Before connecting or disc onnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
• Before removing parts, turn ig nition switch OFF and then dis-
connect battery ground cable.
• Do not disassemble ECM.
• If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-c ontrol at its initial value. So,
engine operation can vary slight ly in this case. However, this
is not an indication of a malf unction. Do not replace parts
because of a slight variation.
• If the battery is disconnected, the following emission-related
diagnostic information will be lost within 24 hours.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
• When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
• Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and cond enser, thus resulting in dam-
age to ICs.
• Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to prevent engine control system mal-
functions due to receiving externa l noise, degraded operation
of ICs, etc.
• Keep engine control system parts and harness dry.
• Before replacing ECM, perform ECM Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-71, "
Reference Value".
• Handle mass air flow sensor carefully to avoid damage.
• Do not clean mass air flow senso r with any type of detergent.
• Do not disassemble electric th rottle control actuator.
• Even a slight leak in the air intake system can cause serious
incidents.
• Do not shock or jar the camsh aft position sensor (PHASE),
crankshaft position sensor (POS).

PRECAUTIONS
•
After performing each TROUBLE DIAGNOSIS, perform DTC
CONFIRMATION PROCEDURE or Component Function
Check. The DTC should not be displayed in the DTC Confir-
mation Procedure if the repair is completed. The Component
Function Check should be a good result if the repair is com-
pleted.
• When measuring ECM signals with a circuit tester, never allow
the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
• Do not operate fuel pump when there is no fuel in lines.
• Tighten fuel hose clamps to the specified torque.
• Do not depress accelerator pedal when starting.
• Immediately after starting, do not rev up engine unnecessar-
ily.
• Do not rev up engine just prior to shutdown.

Exhaust Valve Timing Control Solenoid ValveINFOID:0000000012431286
Exhaust valve timing control solenoi
d valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The exhaust valve timing control solenoid valve changes the oil
amount and direction of flow through exhaust valve timing control
unit or stops oil flow.
The longer pulse width retards valve angle.
The shorter pulse width advances valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the exhaust valve angle at the control
position.
Fuel InjectorINFOID:0000000012431287
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.
Fuel PumpINFOID:0000000012431288
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for a few seconds after the ignition switch is turned ON to improve engine
start ability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and cam-
shaft position sensor (PHASE), it knows that the engi ne is rotating, and causes the pump to operate. If the
engine speed signal is not received when the ignition s witch is ON, the engine stalls. The ECM stops pump
operation and prevents battery discharging, thereby improving safety. The EC M does not directly drive the fuel
pump. It controls the ON/OFF fuel pump rela y, which in turn controls the fuel pump.
