Exhaust System InspectionS7RS0B0206006
WARNING!
To avoid danger of being burned, do not
touch exhaust system when it is still hot.
Any service on exhaust system should be
performed when it is cool.

When carrying out periodic maintenance, or the vehicle
is raised for other service, check exhaust system as
follows:
• Check rubber mountings for damage, deterioration, and out of position.
• Check exhaust system for leakage, loose connections, dents and damages.
If bolts or nuts are loose, tighten them to specification.
• Check nearby body areas for damaged, missing or mispositioned parts, ope n seams, holes, loose
connections or other defects which could permit
exhaust fumes to seep into the vehicle.
• Make sure that exhaust system components have enough clearance from the underbody to avoid
overheating and possible damage to floor carpet.
• Any defects should be fixed at once.
Spark Plug ReplacementS7RS0B0206007
Replace spark plugs with new ones referring to “Spark
Plug Removal and Installation in Section 1H”.
Air Cleaner Filter InspectionS7RS0B0206008
1) Remove air cleaner case clamps.
2) Take air cleaner filter out of case.
3) Check that filter is not excessively dirty, damaged or oily, clean filter with compressed air from air outlet
side of filter.
4) Install air cleaner filter and Clamp cap securely.
Air Cleaner Filter ReplacementS7RS0B0206009
Replace air cleaner filter with new one according to
Steps 1), 2) and 4) of “Air Cleaner Filter Inspection”.
Fuel Lines and Connections InspectionS7RS0B0206010
Visually inspect fuel lines and connections for evidence
of fuel leakage, hose cracking and damage. Make sure
all clamps are secure.
Repair leaky joints, if any.
Replace hoses that are suspected of being cracked.

Ignition System
General Description
Ignition System ConstructionS7RS0B1801001
The ignition system is an electronic (distributorless) ignition system. It consists of the parts as described below.
• ECM
It detects the engine and vehicle conditions through the si gnals from the sensors, determines the most suitable
ignition timing and time for electricity to flow to the primar y coil and sends a signal to the ignitor (power unit) in the
ignition coil assembly.
• Ignition coil assembly (including an ignitor)
The ignition coil assembly has a built -in ignitor which turns ON and OFF the current flow to the primary coil
according to the signal from ECM. When the current flow to the primary coil is turned OFF, a high voltage is induced
in the secondary coil.
• High-tension cords and spark plugs
• CMP sensor (Camshaft position sensor) and CKP sensor (Crankshaft position sensor)
Using signals from these sensors, ECM identifies the specific cylinder whose piston is in the compression stroke,
detects the crank angle and adjusts in itial ignition timing automatically.
• TP sensor, ECT sensor, MAP sensor, MAF sensor, IAT sensor, knock sensor and other sensors / switches
Although this ignition system does not have a distributor, it has two ignition coil assemblies (one is for No.1 and No.4
spark plugs and the other is for No.2 and No.3 spark plugs). W hen an ignition signal is sent from ECM to the ignitor in
the ignition coil assembly for No.1 and No.4 spark plugs, a high voltage is induced in the secondary coil and that
passes through the high-tension cords and causes No.1 and No.4 spark plugs to spark simultaneously. Likewise,
when an ignition signal is sent to the ignitor in the ot her ignition coil assembly, No.2 and No.3 spark plugs spark
simultaneously.
