NOTICES, CAUTIONS, AND WARNINGS
As you read through the various procedures, you will encounter Notices, Cautions and Warnings. Each one is there for a specific purpose. Notices give you added information that will assist you in completing a particular procedure. Cautions
present you from making an error that could damaged the vehicle. Warnings remind you to be especially careful in specific areas where carelessness can cause personal injury.
The following items contain general procedures you should alwys follow when working on a vehicle :
PROTECTION OF THE VEHICLE
•Always cover fenders, seats, and floor areas before starting work.
Operate the engine only in a well-ventilated area to avoid carbon monoxide poisoning.
A WORD ABOUT SAFETY
The following precautions must be followed when jacking up the vehicle:
1.Block the wheels.
2.Use only the specified jacking positions.
3.Support the vehicle with safety stands.
The engine compartment must be clear of tools and people before starting the engine.
PREPARATION OF TOOLS AND MEASURING EQUIPMENT
1. All necessary tools and measuring equipment should be available before starting any work.
SPECLAL SERVICE TOOLS (SST'S)
1.Use special service tools when they are required. SST's can be found under "preparation" prior to any procedure requiring them.
REMOVAL OF PARTS
1.Begin work only after first learning which parts and subassemblies must be removed and disassembled for replacement for repair.
DISASSEMBLY
1.If the disassembly procedure is complex, requiring many parts to be disassembled, all parts should be disassembled in a way that will not affect their performance or external appearance and identified so that assembly can be performed easily and efficiently.
2.Inspection of parts
When removed, each part should be carefully inspected for malfunction, deformation, damage, or other problems.
3.Arrangement of parts
All disassembled parts should be carefully arranged for assembly. Separate or identify the parts to be replaced form those that will be reused.
4.Cleaning parts for reuse
All parts to be reused should be carefully and thoroughly cleaned according to the appropriate method.
REASSEMBLY
Standard values, such as torques and certain adjustments, must be strictly observed in the assembly of all parts. When removed, the following parts should be replaced with new ones:
1.Oil seals
2.O-rings
3.Cotter pins
4.Gaskets
5.Lock washers
6.Nylon nuts
Depending on location:
1.Sealant should be applied or new gaskets used.
2.Oil should be applied to the moving components of parts.
3.Specified oil or grease should be applied at the prescribed locations (such as oil seals) before assembly.
ADJUSTMENT
1. Use appropriate gauges and/or testers when making adjustments.
RUBBER PARTS AND TUBING
1. Prevent gasoline or oil from getting on rubber parts or tubing.
ELECTRICAL TROUBLESHOOTING TOOLS
1.Test Light
The test light, as shown in the figure, uses a 12V bulb. The two lead wires should be connected to probes. The test light is used for simple voltage checks and in checking for short circuits.
When checking the engine control module (ECM), never use a bulb exceeding 3.4W.
2.Jumper Wire
The jumper wire is used for testing by shorting across switch terminals and ground connections.
Do not connect a jumper wire from the power source line to a body ground. Such a connection may cause damage to harnesses or electronic components.
3.Voltmeter
The DC voltmeter is used to measure circuit voltage. A voltmeter with a range of 15V or more is used by connecting the positive (+) probe to the point where voltage is to be measured and the negative (-) probe to a body ground.
4.Ohmmeter
The ohmmeter is used to measure the resistance between two points in a circuit to check for continuity, and in diagnosis of short circuits.
Do not attempt to connect the ohmmeter to any circuit to which voltage is applied ; this may bum or otherwise damage the ohmmeter.
ELECTRICAL PARTS
1.Battery Cable
Before disconnecting connectors replacing electrical parts, disconnect the negative battery cable.
CONNECTORS
1.Removal of connector
(1)Never pull on the wiring harness when disconnecting connectors.
(2) Connectors can be removed by pressing or pulling the lock lever..
2.Locking a connector
Listen for a click when locking connectors. This sound indicates that they are securely locked.
3.Inspection
(1)When a tester is being used to check for continuity or to measure voltage, insert the tester probe from the wire harness side.
(2)Check the terminals of waterproof connectors from the connector side, because they cannot be accessed from the wire harness side.
•Use a fine wire to prevent damage to the terminal.
•Do not damage the terminal when inserting the tester lead.
Terminals
1.Inspection
Pull lightly on individual wires to ensure that they are secured in the terminal.
2.Replacement or terminals
Use the appropriate tools to remove the terminal as shown.
When installing the terminal, be sure to insert it until it locks securely.
(1)Female
Insert a thin piece of metal from the terminal side of the connector, and with the terminal locking tab pressed down, pull the terminal out from the connector.
(2)Male
Insert a thin piece of metal from the terminal side of the connector, and with the terminal locking tab pressed down, pull the terminal out from the connector.
3.Sensors, switches, and relays
Always handle sensors, switches, and relays carefully. Do not drop them or accidently strike them against other parts.
4.Wiring color codes.

GENERAL DESCRIPTION
Ignition system overview
The Dual Overhead Cam(DOHC) Engine Ignition System is now a Distributorless Ignition System(DLI) type. This system is similar to the one currently used on Sephia/Shuma vehicles. The key components of this system are :
•2 Separate Coil Packs
•A Crankshaft Position Sensor that provides engine RPM information to the ECM.
•An Ignition Control Module built into the ECM.
•A Canshaft Position Sensor that provides engine firing order information to the ECM
•Spark Plug Wires and Spark Plugs
Ignition system function
In a conventional ignition system, the ignition coil produces a high voltage current and the disributor thenrelays this current at the required time, to each spark plug. In the disctributirless ignition system, two sensors the camshaft position sensor and the crankshaft position sensor, tell the Engine Control Module (ECM) which cylinder is ready to fire.
The ECM then sends an ignition signal to an electronic ignition coil. This ignition coil then produces and sends a high voltage current to the proper spark plug.
Electronic spark advance system
Ignition Timing is determined and set within the ECM based on signals from various sensors and switches.
Optimum performance is gained with this system. The ECM varies ignition timing according to engine speed, intake air amountm coolant temperature and other conditions.
•Timing specification at idle is : 8 ± 5° BTDC
•Timing is not adjustable.
Ignition system components
The mechanical, rotating high-voltage distrivutor mechanism has been replaced by static electronically controlled components. These components are described below.
Ignition coil
1.Two ignition coil are used in this system. The engine locates them directly above the #2 and #4 spark plugs. The coil resistance is dentical for these two coils and there is no maintenance required for them.
If determined to be faulty, they must be replaced.
High-tension leads
The high-tension leads connect the two ignition coils to the spark plugs. Their function is basically the same as on the previous system. Because of their shorter length, the DLI high-tension leads enhance the ignition systems delivered voltage. In addition, they reduce the wave interference from one high tension wire to another.
Spark plugs
The spark plugs provide the air gap necessary to produce an arc from the electrical energy coming in from the ignition coil. This arc then ignites the fuel/air mixture in the cylinder, producing power.
