SUNLOAD SENSOR
Component DescriptionINFOID:0000000001547363
COMPONENT DESCRIPTION
Sunload Sensor
The sunload sensor (1) is located on the instrument upper mask. It
detects sunload entering through windshield by means of a photo
diode. The sensor converts the sunload into a current value which is
then input into the front air control.
SUNLOAD INPUT PROCESS
The front air control also includes a processing circuit which averages the variations in detected sunload over
a period of time. This prevents drastic swings in the ATC system operation due to small or quick variations in
detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor will vary whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-
ingly.
Sunload Sensor Diagnosis ProcedureINFOID:0000000001547364
DIAGNOSTIC PROCEDURE FOR SUNLOAD SENSOR
SYMPTOM: Sunload sensor circuit is open or shorted.
LEDs of intake switch (FRE, REC) does not illuminate as a result of
performing self-diagnosis STEP-2.
1.CHECK VOLTAGE BETWEEN SUNLOAD SENSOR AND GROUND
1. Turn ignition switch OFF.
2. Disconnect sunload sensor connector.
3. Turn ignition switch ON.
4. Check voltage between sunload sensor harness connector M94
terminal 1 and ground.

ILLUMINATION CONTROL SYSTEM
ILLUMINATION CONTROL SYSTEM
System DiagramINFOID:0000000001730918
System DescriptionINFOID:0000000001730919
The illumination lamps operation is dependent upon the position of the lighting switch (combination switch).
When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated) the BCM
(body control module) receives input requesting the parking lamps to illuminate. This input is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs
power to the parking and illumination lamps, which then illuminate.
BATTERY SAVER CONTROL
When the lighting switch (combination switch) is in the 1ST or 2ND position and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated. Under this condition, the illumination
lamps remain illuminated for 30 minutes unless the lighting switch position is changed. If the lighting switch
position is changed, then the illumination lamps are turned off after a 30 second delay. When the lighting
switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after illumination lamps
have been turned off by the battery saver control, the illumination lamps illuminate again.

Part name Description
BCMThe BCM monitors the lighting switch position with the combina-
tion switch reading function. The BCM requests, via CAN com-
munication, that the IPDM E/R activate the tail lamp relay.
IPDM E/RThe IPDM E/R activates the tail lamp relay based on inputs re-
ceived from the BCM via the CAN communication network.
Combination switchThe combination switch provides input to the BCM about the light-
ing switch position.

Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSION-
ER"
INFOID:0000000001726696
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
 Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
General precautions for service operationsINFOID:0000000001726697
 When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
 When removing parts with a screw driver or other tool, protect parts by wrapping them with vinyl or tape.
 Keep removed parts protected with cloth.
 If an non-reuseable part is removed, replace it with a new one.
 After re-assembly has been completed, make sure each part functions correctly.
 Never work with wet hands.
 Turn the lighting switch OFF before disconnecting and connecting the connector.
 Do not use organic solvent (paint thinner or gasoline) to clean lamps or remove sealant residue.
