Ignition System

2007 > 2.7L V6 GASOLINE >
DESCRITION
Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data
for the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).
The engine operating conditions (speed, load, warm- up condition, etc.) are detected by the various sensors. Based on
these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. The
ignition coil is activated, and timing is controlled.

ON-VEHICLE INSPECTION
SPARK TEST
1. Remove the ignition coil connector(A).
Disconnect the iguition coil connector while pulling up tre connector lock.
2. Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug.
4. Install the spark plug to the ignition coil.
5. Ground the spark plug to the engine.
6.Check is spark occurs while engine is being cranked.
To prevent fuel being injected from injectors while the engine is being cranked, remove the fuel pump(A) relay
from the fuse box.
Crank the engine for no more than 5 ~ 10 seconds.
7. Inspect all the spark plugs.
8. Using a spark plug socket, install the spark plug.
9. Install the ignition coil.
10. Reconnect the ignition coil connector.

INSPECT SPARK PLUG
1.Inspect the electrodes(A) an ceramic insulator(B).
INSPECTION OF ELECTRODES
Condition Dark deposits White deposits
Description a.
Fuel mixture too rich
b. Low air intake a.
Fuel mixture too lean
b. Advanced ignition timing
c. Insufficient plug tightening torque
2. Check the electrode gap (A).
Standard : 1.0 ~ 1.1 mm (0.0394 ~ 0.0433 in.)

INSPECT IGNITION COIL
1.Measure the primary coil resistance between terminals (+) and ( - ).
Standard : 0.0715 ± 0.015Ω
Mesure the resistance between the terminals No.1 and No.3.

2007 > 2.7L V6 GASOLINE >
ON-VEHICLE INPECTION
a.Check that the battery cables are connected to the correct terminals.
b. Disconnect the battery cables when the battery is given a quick charge.
c. Never disconnect the battery while the engine is running.
CHECK BATTERY VOLTAGE
1.If 20 minutes have not passed since the engine was stopped, turn the ignition switch ON and turn on the electrical
system (headlamp, blower motor, rear defogger etc.) for 60 seconds to remove the surface charge.
2. Turn the ignition switch OFF and turn off the electrical systems.
3. Measure the battery voltage between the negative ( - ) and positive (+) terminals of the battery.
Standard voltage : 12.5 ~ 12.9V at 20°C(68°F)
If the voltage is less than specification, charge the battery.
CHECK THE BATTERY TERMINALS AND FUSES
1.Check that the battery terminals are not loose or corroded.
2. Check the fuses for continuity.
INSPECT DRIVE BELT
Visually check the belt for excessive wear, frayed cords etc.
If any defect has been found, replace the drive belt.
Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should
be replaced.
VISUALLY CHECK ALTERNATOR WIRING AND LISTEN FOR ABNORMAL NOISES
1.Check that the wiring is in good condition.
2. Check that there is no abnormal noise from the alternator while the engine is running.
CHECK DISCHARGE WARNING LIGHT CIRCUIT
1.Warm up the engine and then turn it off.
2. Turn off all accessories.
3. Turn the ignition switch "ON". Check that the discharge warning light is lit.
4. Start the engine. Check that the light is lit.
If the light does not go off as specified, troubleshoot the discharge light circuit.
INSPECT CHARGING SYSTEM
VOLTAGE DROP TEST OF ALTERNATOR OUTPUT WIRE
This test determines whether or not the wiring between the alternator "B" terminal and the battery (+) terminal is good
by the voltage drop method.
PREPARATION

1.Turn the ignition switch to "OFF".
2. Disconnect the output wire from the alternator "B" terminal. Connect the (+) lead wire of ammeter to the "B"
terminal of alternator and the ( - ) lead wire of ammeter to the output wire. Connect the (+) lead wire of voltmeter to
the "B" terminal of alternator and the ( - ) lead wire of voltmeter to the (+) terminal of battery.
TEST
1.Start the engine.
2. Turn on the headlamps and blower motor, and set the engine speed until the ammeter indicates 20A.
And then, read the voltmeter at this time.
RESULT
1.The voltmeter may indicate the standard value.
Standard value: 0.2V max
2. If the value of the voltmeter is higher than expected (above 0.2V max.), poor wiring is suspected. In this case
check the wiring from the alternator "B" terminal to the battery (+) terminal. Check for loose connections, color
change due to an over - heated harness, etc. Correct them before testing again.
3. Upon completion of the test, set the engine speed at idle.
Turn off the headlamps, blower motor and the ignition switch.
OUTPUT CURRENT TEST
This test determines whether or not the alternator gives an output current that is equivalent to the normal output.
PREPARATION
1.Prior to the test, check the following items and correct as necessary.
Check the battery installed in the vehicle to ensure that it is good condition. The battery checking method is
described in the section "Battery".
The battery that is used to test the output current should be one that has been partially discharged. With a fully
charged battery, the test may not be conducted correctly due to an insufficient load.
Check the tension of the alternator drive belt. The belt tension check method is described in the section "Inspect
drive belt".
2. Turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Disconnect the alternator output wire from the alternator "B" terminal.
5. Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire. Be sure
to connect the ( - ) lead wire of the ammeter to the disconnected output wire.
Tighten each connection securely, as a heavy current will flow. Do not rely on clips.
6. Connect a voltmeter (0 to 20V) between the "B" terminal and ground. Connect the (+) lead wire to the alternator "B"
terminal and ( - ) lead wire to a good ground.
7. Attach an engine tachometer and connect the battery ground cable.
8. Leave the engine hood open.
