System Description INFOID:0000000000951259
OPERATION DESCRIPTION
• BCM detects that the rear window defogger switch is turned ON when the ignition switch is ON, and then
transmits the rear window defogger switch signal to IPDM E/R via CAN communication for approximately 15
minutes.
• IPDM E/R turns rear window defogger relay ON when it receives the rear window defogger switch signal.
Then, it transmits the rear window defogger ON signal to ECM via CAN communication.
• The power is supplied to the rear window defogger and door mirror defogger (with mirror defogger) when the
rear window defogger relay is turned ON.
TIMER FUNCTION
• BCM transmits the rear window defogger switch signal to IPDM E/R for approximately 15 minutes when the
rear window defogger switch is turned ON with the ignition switch ON. Then, IPDM E/R operates the rear
window defogger and door mirror defogger (with mirror defogger).
• The timer is cancelled if the rear window defogger switch is pressed again during timer operation. BCM
stops the output of rear window defogger switch signal. The same reaction also occurs during timer opera-
tion if the ignition switch is turned OFF.

Auto active test

Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
• Oil pressure warning lamp
• Rear window defogger
• Front wiper (LO, HI)
• Parking lamps
• License plate lamps
• Tail lamps
• Front fog lamps
• Headlamps (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan (LO, HI)
Operation procedure
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
cardiagn.com
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the
ignition switch OFF.
CAUTION:
Close passenger door.
4. Turn the ignition switch ON within 10 seconds. Then the horn sounds once and the auto active test starts.
5. The oil pressure warning lamp starts blinking when the auto active test starts.
6. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system.
• Never start the engine.
Inspection in auto active test mode
When auto active test mode is actuated, the following 6 steps are repeated 3 times.

• IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto K
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

REAR WIPER CONTROL
BCM detects a rear wiper stopping position according to a rear wiper auto stop signal. G
When a rear wiper auto stop signal is in the condition listed below, BCM stops power supply to rear wiper after
rear wiper is activated for five seconds.
H

ON input 5 seconds. I
ON The signal does not change for 5 seconds.
NOTE:
The above operation is repeated when operating the rear wiper switch one minute after the stop of the rear J
wiper caused by Fail-safe.
TURN SIGNAL LAMP CONTROL
K
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE: DEF
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction. M
Auto Light Control

Headlamp is turned ON.
N
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

PRECAUTION A
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT B
PRE-TENSIONER" INFOID:0000000000951296
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along C
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. D
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING: E
• 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.
F
• 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 SRS section.
cardiagn.com
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this G
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.

REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of
drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive silver
composition on break with drawing pen. Slightly overlap existing
heat wire on both sides [preferably 5 mm (0.20 in)] of the break.

4. After repair has been completed, check repaired wire for conti-
nuity. This check should be conducted 10 minutes after silver

composition is deposited.
Do not touch repaired area while test is being conducted.

5. Apply a constant stream of hot air directly to the repaired area

for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24
hours.
