Ignition coil KIA CARNIVAL 2007 User Guide

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.

REMOVAL
IGNITION COIL
1. Remove the engine cover.
2. Remove the ignition coil (A).
3.Remove the ignition coil.
4. Installation is the reverse of removal.
REPLACEMENT
SPARK PLUG
1. Remove the ignition coil connector(A).
2.Remove the ignition coil.
3. Using a spark plug socket, remove the spark plug.
Be careful that no contaminates enter through the spark plug holes
4. When replacing the spark plug, always use the long reach type spark plug.

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 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.

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.

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.
