Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001534589
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.
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.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect
INFOID:0000000001534590
NOTE:
 This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
 Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
 Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

System DescriptionINFOID:0000000001697542
Operation Description
 Turn rear window defogger switch ON when the ignition switch is turned ON. Then controller (auto amp.)
(rear window defogger switch) transmits rear window defogger switch signal to BCM.
 BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
 Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and
operate when rear window defogger relay turns ON.
 BCM transmits rear window defogger control signal to IPDM E/R via CAN communication when rear window
defogger operates.
 Rear window defogger ON is displayed when controller (auto amp.) receives signals.
Timer function
 BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch
is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door
mirror defogger) operate.
 Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.

REAR WINDOW DEFOGGER SWITCH
DescriptionINFOID:0000000001697548
 The rear window defogger is operated by turning the rear window defogger switch ON.
 Turns the indicator lamp in the rear window defogger switch ON when operating the rear window defogger.
Component Function CheckINFOID:0000000001697549
1. CHECK REAR WINDOW DEFOGGER SWITCH FUNCTION
Check that the indicator lamp of rear window defogger illuminates with rear window defogger switch ON.
Is the inspection result normal?
YES >> Rear window defogger switch function is OK.
NO >> Refer to DEF-11, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001697550
1. CHECK CONTROLLER (AUTO AMP.) (REAR WINDOW DEFOGGER SWITCH)
Does controller (auto amp.) operate normally?
Is the inspection result normal?
YES >> Inspection End.
NO >> GO TO 2
2. CHECK REAR WINDOW DEFOGGER SWITCH INDICATOR CIRCUIT
