KIA CARNIVAL 2007 Workshop Manual

2007 > 2.7L V6 GASOLINE >
INSPECTION
While operating the components, check whether the operations are normal as shown in the timing chart.
1. Once Generator "L" is ON, if the defogger is switched ON, the defogger will stay ON for 20 minutes duration.
2. If defogger switch is pressed again (see Step 1), or if ignition is switched OFF, the defogger will shut OFF.
3. If Generator "L" is OFF, the defogger will shut OFF.

Rear Glass Defogger

Rear Glass Defogger Printed Heater

2007 > 2.7L V6 GASOLINE >
INSPECTION
Wrap tin foil around the end of the voltmeter test lead to prevent damaging the heater line. Apply finger pressure
on the tin foil, moving the tin foil along the grid line to check for open circuits.
1.Turn on the defogger switch and use a voltmeter to measure the voltage of each heater line at the glass center
point. If a voltage of approximately 6V is indicated by the voltmeter, the heater line of the rear window is
considered satisfactory.
2.If a heater line is burned out between the center point and (+) terminal, the voltmeter will indicate 12V.
3.If a heater line is burned out between the center point and ( - ) terminal, the voltmeter will indicate 0V.

4.To check for open circuits, slowly move the test lead in the direction that the open circuit seems to exist. Try to find
a point where a voltage is generated or changes to 0V. The point where the voltage has changed is the open-
circuit point.
5.Use an ohmmeter to measure the resistance of each heater line between a terminal and the center of a grid line,
and between the same terminal and the center of one adjacent heater line. The section with a broken heater line
will have a resistance twice as that in other sections. In the affected section, move the test lead to a position where
the resistance sharply changes.
REPAIR OF BROKEN HEATER LINE
Prepare the following items:
1. Conductive paint.
2. Paint thinner.
3. Masking tape.
4. Silicone remover.
5. Using a thin brush :
Wipe the glass adjacent to the broken heater line, clean with silicone remover and attach the masking tape as
shown. Shake the conductive paint container well, and apply three coats with a brush at intervals of about 15
minutes apart. Remove the tape and allow sufficient time for drying before applying power. For a better finish,
scrape away excess deposits with a knife after the paint has completely dried. (Allow 24 hours).

Rear Glass Defogger Switch

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Disconnect the negative ( - ) battery terminal.
2. Remove the center facia panel, console lower cover and center air vent (A) after loosening screws. Take care not
to damage fixing clips.
3.Remove the center facia panel switch and air control panel (A) after loosening screws.
4.Disconnect the air control panel connector (A).
5.Installation is the reverse of removal.

Rear Glass Defogger Timer

2007 > 2.7L V6 GASOLINE >
INSPECTION
While operating the components, check whether the operations are normal as shown in the timing chart.
1. The defog function can be activated only when engine is running and ignition key is in RUN position.
If the defogger is switched ON, the defogger will stay ON for 20 minutes duration.
While Windshield Defog is on, the windshield defog button is illuminated
If the switch is pushed again while defog is already active, defog stops.
If the engine stops while defog is on, defog stops and it is not automatically turned on when the engine is started
again.
Rear defog works exactly in the same way as windshield defog using the Rear Defog Switch button as input.
2.Rear Defog Pause
When IPM receives tailgate flasher control CAN message transition to tailgate flash value, rear defog is inhibited for
30s.
The 20 min rear defog timer is frozen during this pause.
If the user turns on rear defog function while this pause is going on, rear defog is set to ON only at the end of the
pause.
This pause has no impact on Rear Defog Switch illumination.
When IPM receives tail gate open CAN message transition to OPEN value, this 30 s rear defog pause is also
started, it works the same way as described above.
