OIL AND FILTER REPLACEMENT
CAUTION:
wProlonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi±
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
wCare should be taken, therefore, when changing
engine, oil to minimize the frequency and length of
time your skin is exposed to used engine oil. Protec±
tive clothing and gloves that cannot be penetrated
by oil should be worn. The skin should be thorought±
hly washed with soap and water, or use water±less
hand cleaner, to remove any used engine oil. Do not
use gasoline, thinners, or solvents.
wIn order to preserve the environment, used oil and
used oil filter must be disposed of only at designated

HOW TO PROCEED WITH TROUBLESHOOTING
The Engine Control System broadly consists of the sensors, Engine Control Module (ECM) and actuators.
The ECM receives signals from various sensors, judges the operating conditions and determines the
optimum injection duration, timing, ignition timing and idle speed.
In general, the Engine Control System is considered to be a very intricate system to troubleshoot. But, the
fact is that if you proceed to inspect the circuit one by one following the procedures directed in this manu-
al, troubleshooting of this system is not complex.
This section explains the most ideal method of troubleshooting and tells how to carry out the necessary
repairs.
1. CUSTOMER PROBLEM ANALYSIS
Using the customer problem analysis check sheet for reference, ask the customer in as much details
as possible about the problem.
2. CHECK AND CLEAR DIAGNOSTIC TROUBLE CODE (PRECHECK)
Before confirming the problem symptom, first check the diagnostic trouble code and make a note of
any malfunction code which is output, then clear the code.
HINT: Output of the malfunction code indicates that there is a malfunction in the circuit indicated.
However, it does not indicate whether the malfunction is still occurring or occurred in the past and
returned to normal. In order to determine this, the problem sym toms should be confirmed in step 4
first and the diagnostic trouble code be rechecked in step [6].
Accordingly, if troubleshooting is begun based on the malfunction code only in diagnostic trouble
code check in step [2], it could result in a misdiagnosis, leading to troubleshooting of circuits which
are normal and making it more difficult to locate the cause of the problem.
3. SETTING THE TEST MODE DIAGNOSIS, [4] PROBLEM SYMPTOM CONFIRMATION,
[5] SYMPTOM SIMULATION
In order to find out the trouble more quickly, set the diagnosis check in test mode and with higher
sensing ability of the ECM, confirm the problem symptoms. If the trouble does not reappear, use the
symptom simulation method to make sure the trouble is reproduced.
6. DIAGNOSTIC TROUBLE CODE CHECK IN TEST MODE
Check the diagnostic trouble code in test mode. If the malfunction code is output, proceed to step. If the
normal code is output, proceed to step [7].
7. BASIC INSPECTION
Carry out basic inspection such as the spark check and fuel pressure check, etc.
8. DIAGNOSTIC TROUBLE CODE CHART
If the malfunction code is displayed, proceed to inspect the circuit indicated by the chart for each
code.
9. MATRIX CHART OF PROBLEM SYMPTOMS
If the normal code is displayed in the diagnosis in test mode, perform troubleshooting according to
the inspection order in the Matrix Chart of Problem Symptoms.
10. PARTS INSPECTION
When the Matrix Chart of Problem Symptoms instructs to check the parts, proceed to parts inspection
section included in this manual.
11. CIRCUIT INSPECTION
Determine if the malfunction is the sensor, actuator, wire harness, connector or the ECM.

CHECK FOR MOMENTARY INTERRUPTION
By performing the check for momentary interruption, the place where momentary interruptions or
momentary shorts are occurring due to poor contacts can be isolated.
ADJUSTMENT, REPAIR
After the cause of the problem is located, perform adjustment or repairs by following the inspection
and replacement procedures in this manual.
CONFIRMATION TEST
After completing adjustment or repairs, confirm not only that the malfunction is eliminated, but also
conduct a test drive, etc., to make sure the entire Engine Control System is operating normally.
