• The seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and buckles show no damage and continue to operate properly).
• The seat belt was damaged in an accident. (i.e. torn webbing, bent retractor or guide, etc.)
• The seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
• Anchor bolts are deformed or worn out.
• The seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal collision
in which the air bags are deployed.
PRELIMINARY CHECKS
1. Check the seat belt warning lamp/chime for proper operation as follows:
a. Switch ignition ON. The seat belt warning lamp should illuminate. Also, the seat belt warning chime should sound for about seven seconds.
b. Fasten driver's seat belt. The seat belt warning lamp should go out and the chime (if sounding) should stop.
2. If the air bag warning lamp is blinking, conduct self-diagnosis using CONSULT-III, and air bag warning
lamp. Refer to SRS-19, "
SRS Operation Check".
3. Check that the seat belt retractor, seat belt anchor and buckle bolts are securely attached.
4. Check the shoulder seat belt guide and shoulder belt height adjuster for front seats. Make sure guide
swivels freely and that webbing lays flat and does not bind in guide. Make sure height adjuster operates
properly and holds securely.
5. 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. Make sure 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. Dirt build-up
in the loops of the upper anchors can caus e the seat belts to retract slowly.
c. Fasten the seat belt. Check the seat belt returns sm oothly and completely to the retractor. If the webbing
does not return smoothly, the cause may be an accu mulation of dust or dirt. Use the “SEAT BELT TAPE
SET” and perform the following steps.
Inspect the front seat belt though-anchor
1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Use a clip or other device to attach t he seat belt at the center pillar webbing opening.
3. Pass a thin wire though the D-ring anchor webbing opening. Hold both end\
s of the wire and pull taut while moving it up and down several times along the webbing opening surface to remove matter stuck
there.
4. Any dirt that cannot be removed with the wire can be removed by cleaning the opening with a clean
cloth.
5. Apply tape at the point where the webbing contacts the though-anchor webbing opening.
NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip attaching the seat bel t 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 Locki ng 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 Automati c 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 part ially, 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.
