CAN communication control
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN
communication recovers normally, it also returns to normal control.

Ignition relay malfunction detection function
 IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
 IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation
coil circuit.
 If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to
alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

Front wiper control
IPDM E/R detects the front wiper stop position with the front wiper auto stop signal.
When the front wiper auto stop signal is in the conditions listed below, IPDM E/R repeats a front wiper 10 sec-
onds operation and 20 seconds stop five times.
NOTE:
This operation status can be confirmed on the IPDM E/R “Data Monitor” that displays “BLOCK” for the item
“WIP PROT” while the wiper is stopped.

PRE-INSPECTION FOR DIAGNOSTIC
Basic InspectionINFOID:0000000001404144
The engine start function, door lock function, and NATS in the Intelligent Key system are closely related to
each other regarding control. Narrow down the functional area in question by performing basic inspection to
identify which function is malfunctioning. The vehicle security function can operate only when the door lock is
operating normally. Therefore, it is easy to identify any factor unique to the vehicle security system by perform-
ing the vehicle security operation check after basic inspection.
1.CHECK DOOR LOCK OPERATION
Check the door lock for normal operation with the Intelligent Key and door request switch.
Successful door lock operation with the Intelligent Key and request switch indicates that the remote keyless
entry receiver and inside key antenna required for engine start are functioning normally.
Identify the malfunctioning point by referring to the DLK section if the door cannot be unlocked.
Can the door be locked with the Intelligent Key and door request switch?
YES >> GO TO 2.
NO >> Refer to XX-XX, "*****"
.
2.CHECK IGNITION KNOB SWITCH OPERATION-1
With all registered Intelligent Keys, check if ignition knob can rotate when carrying Intelligent Key inside the
vehicle.
Does ignition knob rotate?
YES >> GO TO 3.
NO >> Refer to SEC-76, "
Symptom Table".
3.CHECK IGNITION KNOB SWITCH OPERATION-2
Insert registered mechanical key into key cylinder, and check if ignition knob can rotate. Check for all regis-
tered mechanical keys.
Does ignition knob rotate?
YES >> GO TO 4.
NO (Does not rotate with some of mechanical keys)>>Perform mechanical key registration.
NO (Does not rotate with all mechanical keys)>>Refer to SEC-76, "
Symptom Table".
4.CHECK VEHICLE SECURITY SYSTEM
Check the vehicle security system for normal operation.
The vehicle security function can operate only when the door lock function is operating normally.
Therefore, it is easy to identify any factor unique to the vehicle security by performing the vehicle security
operation check after this basic inspection.
>> Go to SEC-77, "
Vehicle Security Operation Check".
Vehicle Security Operation CheckINFOID:0000000001404145
1.INSPECTION START
Turn ignition switch “OFF” and pull out mechanical key from key cylinder.
NOTE:
Before starting operation check, open front windows.
>> GO TO 2.
2.CHECK SECURITY INDICATOR LAMP
1. Lock doors using Intelligent Key.
2. Check that security indicator lamp illuminates for 30 seconds.
Security indicator lamp should illuminate.
OK >> GO TO 3.

BCM (BODY CONTROL MODULE)
REAR WIPER CONTROL
BCM detects a rear wiper stopping position according to a rear wiper auto stop signal.
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.
NOTE:
The above operation is repeated when operating the rear wiper switch one minute after the stop of the rear
wiper caused by Fail-safe.
TURN SIGNAL LAMP CONTROL
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:
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.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001404297
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 for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000001404298
 Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
 Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-
tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have
passed.
 The air bag diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the front
of the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or rust
before installation and replace as required.
 The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
 Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
 Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
 After air bag inflates, the front instrument panel assembly should be replaced if damaged.
