ignition KIA CARNIVAL 2007 Owner's Manual

TEST
1.Check to see that the voltmeter reads as the same value as the battery voltage. If the voltmeter reads 0V, and the
open circuit in the wire between alternator "B" terminal and battery ( - ) terminal or poor grounding is suspected.
2. Start the engine and turn on the headlamps.
3. Set the headlamps to high beam and the heater blower switch to HIGH, quickly increase the engine speed to 2,500
rpm and read the maximum output current value indicated by the ammeter.
After the engine start up, the charging current quickly drops.
Therefore, the above operation must be done quickly to read the maximum current value correctly.
RESULT
1.The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good
condition, remove the alternator from the vehicle and test it.
Limit value : 70Ë of the rated current
a.The nominal output current value is shown on the nameplate affixed to the alternator body.
b. The output current value changes with the electrical load and the temperature of the alternator itself.
Therefore, the nominal output current may not be obtained. If such is the case, keep the headlamps on the
cause discharge of the battery, or use the lights of another vehicle to increase the electrical load.
The nominal output current may not be obtained if the temperature of the alternator itself or ambient
temperature is too high.
In such a case, reduce the temperature before testing again.
2. Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Remove the ammeter and voltmeter and the engine tachometer.
5. Connect the alternator output wire to the alternator "B" terminal.
6. Connect the battery ground cable.
REGULATED VOLTAGE TEST
The purpose of this test is to check that the electronic voltage regulator controls voltage correctly.
PREPARATION
1.Prior to the test, check the following items and correct if necessary.
Check that the battery installed on the vehicle is fully charged. The battery checking method is described in the
section "Battery".
Check the alternator drive belt tension. The belt tension check method is described in the section "Inspect drive
belt".
2. Turn ignition switch to "OFF".
3. Disconnect the battery ground cable.
4. Connect a digital voltmeter between the "B" terminal of the alternator and ground. Connect the (+) lead of the
voltmeter to the "B" terminal of the alternator. Connect the ( - ) lead to good ground or the battery ( - ) terminal.
5. Disconnect the alternator output wire from the alternator "B" terminal.

6.Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire.
Connect the ( - ) lead wire of the ammeter to the disconnected output wire.
7. Attach the engine tachometer and connect the battery ground cable.
TEST
1.Turn on the ignition switch and check to see that the voltmeter indicates the following value.
Voltage: Battery voltage
If it reads 0V, there is an open circuit in the wire between the alternator "B" terminal and the battery and the battery
( - ) terminal.
2. Start the engine. Keep all lights and accessories off.
3. Run the engine at a speed of about 2,500 rpm and read the voltmeter when the alternator output current drops to
10A or less
RESULT
1.If the voltmeter reading agrees with the value listed in the regulating voltage table below, the voltage regulator is
functioning correctly. If the reading is other than the standard value, the voltage regulator or the alternator is faulty.

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
The starting system includes the battery, starter, solenoid switch, ignition switch, inhibitor switch (A/T), ignition lock
switch, connection wires and the battery cable.
When the ignition key is turned to the start position, current flows and energizes the starter motor's solenoid coil.
The solenoid plunger and clutch shift lever are activated, and the clutch pinion engages the ring gear.
The contacts close and the starter motor cranks. In order to prevent damage caused by excessive rotation of the
starter armature when the engine starts, the clutch pinion gear overruns.

2007 > 2.7L V6 GASOLINE >
STARTER CIRCUIT TROUBLESHOOTING
The battery must be in good condition and fully charged.
1. Remove the fuel pump relay(A) from the fuse box.
2. With the shift lever in N or P (A/T) or clutch pedal pressed (M/T), turn the ignition switch to "START"
If the starter normally cranks the engine, starting system is OK. If the starter will not crank the engine at all, go to
next step.
If it won't disengage from the ring gear when you release key, check for the following until you find the cause.
a. Solenoid plunger and switch malfunction.
b. Dirty pinion gear or damaged overrunning clutch.
3. Check the battery condition. Check electrical connections at the battery, battery negative cable connected to the
body, engine ground cables, and the starter for looseness and corrosion. Then try starting the engine again.
If the starter cranks normally the engine, repairing the loose connection repaired the problem. The starting system
is now OK.
If the starter still does not crank the engine, go to next step.
4. Disconnect the connector from the S- terminal of solenoid. Connect a jumper wire from the B- terminal of solenoid to
the S- terminal of solenoid.
If the starter cranks the engine, go to next step.
If the starter still does not crank the engine, remove the starter, and repair or replace as necessary.
5. Check the following items in the order listed until you find the open circuit.
a. Check the wire and connectors between the driver's under - dash fuse/relay box and the ignition switch, and
between the driver's under - dash fuse/relay box and the starter.
b. Check the ignition switch (Refer to BE group - ignition system)
c. Check the transaxle range switch connector or ignition lock switch connector.
d. Inspect the starter relay.
STATER SOLENOID TEST
1.Disconnect the field coil wire from the M- terminal of solenoid switch.
2. Connect the battery as shown. If the starter pinion pops out, it is working properly. To avoid damaging the starter,
do not leave the battery connected for more than 10 seconds.
3.Disconnect the battery from the M terminal.
If the pinion does not retract, the hold- in coil is working properly. To avoid damaging the starter, do not leave the
battery connected for more than 10 seconds.

COMPONENT INSPECTION
1.Turn ignition switch OFF.
2. Disconnect PCSV connector.
3. Measure resistance between PCSV terminals 1 and 2.
4.Check that the resistance is within the specification.

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
Modifications to the combustion chamber, intake manifold, camshaft and ignition system form the basic control system.
These items have been integrated into a highly effective system which controls exhaust emissions while maintaining
good driveability and fuel economy.
AIR/FUEL MIXTURE CONTROL SYSTEM [MULTIPORT FUEL INJECTION (MFI) SYSTEM]
This in turn allows the engine to produce exhaust gases of the proper composition to permit the use of a three way
catalyst. The three way catalyst is designed to convert the three pollutants (1) hydrocarbons (HC), (2) carbon
monoxide (CO), and (3) oxides of nitrogen (NOx) into harmless substances. There are two operating modes in the MFI
system.
1. Open Loop air/fuel ratio is controlled by information programmed into the ECM.
2. Closed Loop air/fuel ratio is adjusted by the ECM based on information supplied by the oxygen sensor.
