light KIA CARNIVAL 2007 Owners Manual

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
The auto light control system operates by using the auto light switch.
If you set the multi- function switch to "AUTO" position, the tail lamp and head lamp will be turned automatically on or
off according to external illumination.

Auto Light Sensor

2007 > 2.7L V6 GASOLINE >
INSPECTION
While operating the auto light switch, check if the operations are normal as shown in the timing chart.
1. Auto light sensor value is always read at IGN ON.
2. Light is turned ON after 1sec±0.1sec when auto light sensor value is same as light ON input value.
3. Light is turned OFF after 2sec±0.2sec when sensor value is same as light OFF input value.
4. Tail lamp and head lamp are turned ON when sensor value is same as tail lamp ON input value.
5. Light ON value of sensor is based on the below table.
6. Head lamp signal is output when head lamp switch is ON. After head lamp is turned OFF, head lamp signal output
is immediately stopped if head lamp OFF luminance condition is met at auto light switch ON.

(low beam)
ON 1.77V+/ - 0.08V 0.63V+/ - 0.06V
OFF 3.47V+/ - 0.10V 1.02V+/ - 0.06V
T1 : 2 ± 0.2 sec
T2 : 2 ± 0.2 sec.
REPLACEMENT
Photo & auto light sensor inspection
1. Disconnect the crash pad (Refer to Body group - Crash pad).
2. Remove the Photo & auto light sensor (B) from crash pad.
3.Installation is the reverse of removal.

Daytime Running Lights

Daytime Running LightsControl Module

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.The daytime running unit (A) is integrated in the IPM.
2.Functional diagram.
3.The DRL function operates the Head lamps High Beam at 50% of full illumination. The DRL function is active if :
a. the engine is running
b. the Head lamp multifunction switch is in OFF position or 'Park and Tail lamp' (Auto light function deactivated)
c. The Park break switch is OFF.
When the DRL function is active, the Head lamps High Beam can't be turned ON, except for the Flash To Pass
activation.
4. If the daytime running light is not operated well, Inspect the connector and terminals to be sure they are all making
good contact.
If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
If the terminals look OK, go to step 4.
5. Make these input tests at the connector by using ETM.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the IPM (In - panel module) must be faulty; replace it.

DESCRIPTION
The immobilizer system will disable the vehicle unless the proper ignition key is used, in addition to the currently
available anti- theft systems such as car alarms, the immobilizer system aims to drastically reduce the rate of auto
theft.
1. SMARTRA type immobilizer
a. The SMARTRA system consists of a transponder located in the ignition key, an antenna coil, a SMARTRA unit,
an indicator light and the PCM(ECM).
b. The SMARTRA communicates to the PCM(ECM) (Engine Control Module) via a dedicated communications line.
Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit
to control the SMARTRA.
c. When the key is inserted in the ignition and turned to the ON position, the antenna coil sends power to the
transponder in the ignition key. The transponder then sends a coded signal back through the SMARTRA unit to
the PCM(ECM).
d. If the proper key has been used, the PCM(ECM) will energize the fuel supply system. The immobilizer indicator
light in the cluster will simultaneously come on for more than five seconds, indicating that the SMARTRA unit
has recognized the code sent by the transponder.
e. If the wrong key has been used and the code was not received or recognized by the PCM(ECM) the indicator
light will continue blinking for about five seconds until the ignition switch is turned OFF.
f. If it is necessary to rewrite the PCM(ECM) to learn a new key, the dealer needs the customer's vehicle, all its
keys and the Scan tool (pro) equipped with an immobilizer program card. Any key that is not learned during
rewriting will no longer start the engine.
g. The immobilizer system can store up to four key codes.
h. If the customer has lost his key, and cannot start the engine, contact motor service station.
COMPONENTS OPERATIONS
PCM (Power Train Control Module)
1. The PCM(ECM) carries out a check of the ignition key using a special encryption algorithm, which is programmed
into the transponder as well as the PCM(ECM) simultaneously. Only if the results are equal, the engine can be
started. The data of all transponders, which are valid for the vehicle, are stored in the PCM(ECM).
