NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip fixing the seat belt and check that the webbing returns smoothly.
6. Repeat steps above as 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 of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock 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 wind back into the retractor.
Check the seat belt retractors using the following test(s) to determine if a retractor assembly is operating prop-
erly.
ELR Function Stationary Check
Grasp the shoulder webbing 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 webbing partially. A clicking noise should be heard as the webbing retracts indicating that the
retractor is in the Automatic Locking Retractors (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If
NG, replace the retractor assembly.
4. Allow the entire length of the webbing to retract to cancel the automatic locking mode.
ELR Function Moving Check
WAR NING :
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 driver's 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
and 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 assembly does not lock, per-
form the retractor off-vehicle check.

Trouble Diagnoses with Battery/Starting/Charging System Tester (Charging)NKS003NP
NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be done
as a set from start to finish.
Before starting, perform the preliminary inspection. Refer to SC-32, "
PRELIMINARY INSPECTION" .
1. Stop the operation of the power generation voltage variable control in either of the following procedures.
After selecting “ENGINE” of “SELECT SYSTEM” using CONSULT-II, set the DUTY value of “ALTERNA-
TOR DUTY” to 0% by selecting “ALTERNATOR DUTY” of “ACTIVE TEST”. Continue “ACTIVE TEST”
until the end of inspection. (When the DUTY value is 0 or 100%, the normal power generation is per-
formed according to the characteristic of the IC regulator of the alternator.)
Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC
(P1550 - P1554) of the engine might remain. After finishing the inspection, connect the battery current
sensor connector and erase the self-diagnostic results history of the engine using CONSULT-II.]
2. Turn off all loads on the vehicle electrical system.
3. Perform battery and starting system test with Battery/Starting/
Charging system tester.
4. Press “ENTER” to begin the charging system test.
5. Start engine.
6. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC” is dis-
played.
7. Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle.
Once the increase in engine rpm is detected, press “ENTER” to
continue.
NOTE:
If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.
Some engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect
this without any other action being taken. If this occurs, con-
tinue on with the testing process. The final results will not be affected.
8. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
9. When complete, the tester will prompt you to turn on the follow-
ing electrical loads.
Heater fan set to highest speed. Do not run the A/C or wind-
shield defroster.
Headlamp high beam
Rear window defogger
NOTE:
Do not run the windshield wipers or any other cyclical loads.
