Checking Seat Belt, Buckles, Retractors, Anchors and AdjustersNLS00074
CAUTION:

After any collision, inspect all seat belt assemblies, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in
use during a collision, unless not damaged and properly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision, and replace if damaged or improp-
erly operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal col-
lision where the driver and passenger air bags are deployed.

If any component of seat belt assembly is questionable, do not repair.
Replace as seat belt assembly.

If webbing is cut, frayed, or damaged, replace belt assembly.

Never oil tongue and buckle.

Use a genuine NISSAN seat belt assembly.
For details, refer to Refer to Service Manual in SB section.

Check anchors for loose mounting

Check belts for damage

Check retractor for smooth operation

Check function of buckles and tongues when buckled and released

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS003GB

IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It controls integrated relay via IPDM E/R control cir-
cuit.

IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, and hood switch signal reception, etc.

It controls operation of each electrical part via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
IPDM E/R receives a request signal from each control unit with CAN communication. It controls each system.
CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control unit using two communication lines (CAN L line, CAN H
line), it is possible to transmit maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
Fail- Safe Control

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

Operation of control parts by IPDM E/R during fail-safe mode is as follows:
Control system Transmit control unit Control part
Lamp control BCM

Headlamps (HI, LO)

Front fog lamps

Parking, license plate, side marker and tail lamps
Wiper control BCM Front wipers
Rear window defogger control BCM Rear window defogger
A/C compressor control ECM A/C compressor (magnet clutch)
Cooling fan control ECM Cooling fan
Horn control BCM Horn
Controlled system Fail-safe mode
Headlamp

With the ignition switch ON, the headlamp (low) is ON.

With the ignition switch OFF, the headlamp (low) is OFF.
Parking, license plate side marker and
tail lamps

With the ignition switch ON, the parking, license plate, side marker and tail lamps is ON.

With the ignition switch OFF, the parking, license plate, side marker and tail lamps is OFF.
Cooling fan

With the ignition switch ON, the cooling fan HI operates.

With the ignition switch OFF, the cooling fan stops.
Front wiper Until the ignition switch is turned OFF, the front wiper LO and HI remains in the same status
it was in just before fail-safe control was initiated.
Rear window defogger Rear window defogger relay OFF
A/C compressor A/C compressor OFF
Front fog lamps Front fog lamp relay OFF

Auto Active TestNKS003GG
DESCRIPTION
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to the
following systems:

Rear window defogger

Front wipers

Parking, license plate, side marker and tail lamps

Front fog lamps

Headlamps (Hi, Lo)

A/C compressor (magnetic clutch)

Cooling fan
OPERATION PROCEDURE
1. Close hood and front door (passenger side), and then lift wiper arms away from windshield (to prevent glass damage by wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON, and within 20 seconds, press drivers door switch 10 times (close other doors). Then turn ignition switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once oil pressure warning lamp starts blinking.
6. After a series of operations is repeated three times, auto active test is completed. NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to inspect BL-40, "
Check Door Switch" when the auto active test cannot be performed.
