BCM
BCM : DescriptionINFOID:0000000003805725
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

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 front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.

SEAT BELT RETRACTOR : InspectionINFOID:0000000003848858
AFTER A COLLISION
WARNING:
Inspect all seat belt assemblies including retractors and attached hardware after any collision.
NISSAN/INFINITI recommends that all seat belt assemblies in use during a collision be replaced
unless the collision was minor and the belts show no damage and continue to operate properly. Not
doing so could result in serious personal injury in an accident. Seat belt assemblies not in use during
a collision must also be replaced if either damage or improper operation is noted. Seat belt pre-ten-
sioners must be replaced even if the seat belts are not in use during a frontal collision in which the air
bags are deployed.
Replace any seat belt assembly (including anchor bolts) if:
 The seat belt is in use at the time of a collision (except for minor collisions and the belts, retractors and buck-
les show no damage and continue to operate properly).
 The seat belt is damaged in an accident (i.e. torn webbing, bent retractor or guide, etc.).
 The seat belt attaching point is damaged in an accident. Inspect the seat belt attaching area for damage or
distortion and repair if necessary before installing a new seat belt assembly.
 Anchor bolts are deformed or worn out.
 The seat belt pre-tensioners must be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.
PRELIMINARY CHECKS
1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Turn ignition switch ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime
should sound for about six seconds.
b. Fasten driver seat belt. The seat belt warning lamp should turn OFF and the chime (if sounding) should
stop.
2. If the air bag warning lamp is blinking, conduct self-diagnosis with CONSULT-III and air bag warning lamp.
Refer to SRC-10, "
Diagnosis Description".
3. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
4. Check retractor operation:
a. Fully extend the seat belt webbing and check for twists, tears or other damage.
b. Allow the seat belt to retract. Check that webbing returns smoothly and completely into the retractor. If the
seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth. Because dirt
build-up in the loops of that upper anchors can cause the seat belts to retract slowly.
c. Fasten the seat belt. Check the seat belt returns smoothly and completely to the retractor. If the webbing
does not return smoothly, the cause may be an accumulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
5. Repeat steps above if necessary to check the other seat belts.
SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are Emergency Locking Retractors (ELR) type. In an emergency (sudden stop) the
retractor locks and prevent the webbing from extending any further. All 3-point type seat belt retractors except
the driver's seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also called child
restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt is fully
extended. When the webbing is then retracted partially, the ALR mode automatically locks the seat belt in a
specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat belt
to fully return into the retractor.
Check the seat belt retractors with the following test(s) to determine if a retractor assembly is operating prop-
erly.
ELR Function Stationary Check
