SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock and prevent the belt 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 belt is then retracted partially, the ALR mode automatically locks the seat belt in a
specific position so the belt cannot be extended any further. To cancel the ALR mode, allow the seat belt to
fully wind back into the retractor.
Check the seat belt retractors using the following test(s) to determine if a seat belt retractor and belt assembly
is operating properly.
ELR Function Stationary Check
Grasp the shoulder belt and pull forward quickly. The retractor should lock and prevent the belt from extending
further.
ALR Function Stationary Check
1. Pull out entire length of seat belt from retractor until a click is heard.
2. Retract the belt partially. A clicking noise should be heard as the belt retracts indicating that the retractor is
in the Automatic Locking Retractor (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The belt must lock and not extend any further. If neces-
sary replace the seat belt retractor and belt assembly.
4. Allow the entire length of the belt to retract to cancel the automatic locking mode.
ELR Function Moving Check
WA RN ING:
Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be paved and dry. DO NOT perform the following test on
wet or gravel roads or on public streets and highways. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1. Fasten drivers seat belt. Buckle a passenger into the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop.
The driver and passenger must be prepared to brace themselves in the event the retractor does not lock.
Apply brakes firmly and make a very hard stop.
During stop, seat belts should lock and not be extended. If the seat belt retractor and belt assembly does not
lock, perform the retractor off-vehicle check.
SEAT BELT RETRACTOR OFF-VEHICLE CHECK
1. Remove the seat belt retractor and belt assembly.
2. Slowly pull out belt while tilting the retractor assembly forward from the mounted position without twisting
the retractor assembly as shown in the illustration.

STARTING SYSTEM
Revision: October 20052005 QX56
STARTING SYSTEMPFP:23300
System DescriptionEKS00B7B
Power is supplied at all times:

through 40A fusible link (letter m , located in the fuse and fusible link box)

to ignition switch terminal B.
With the ignition switch in the START position, power is supplied:

from ignition switch terminal ST

to IPDM E/R terminal 21.
With the ignition switch in the ON or START position, power is supplied to IPDM E/R (intelligent power distribu-
tion module engine room) CPU.
With the selector lever in the P or N position, power is supplied:

through A/T assembly terminal 9

to IPDM E/R terminal 48.
Ground is supplied at all times:

to IPDM E/R terminals 38 and 59

through body grounds E9, E15 and E24.
Then the starter relay is turned on.
The IPDM E/R is energized and power is supplied:

from terminal 19 of the IPDM E/R

to terminal 1 of the starter motor windings.

CHARGING SYSTEMPFP:23100
System DescriptionEKS00B7H
The generator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times:

to generator terminal 4

through 10A fuse (No. 30, located in the fuse and fusible link box).
Terminal 1 supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 detecting the input voltage. The charging circuit is protected by the
140A fusible link (letter a , located in the fusible link box).
Ground is supplied:

to generator terminal 2

through body ground E203.
With the ignition switch in the ON or START position, power is supplied:

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 24 for the charge warning lamp.
Ground is supplied to terminal 13 of the combination meter through terminal 3 of the generator. With power
and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient volt-
age with the engine running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a fault is indicated.
