DIAGNOSTIC INFORMATION AND PROCEDURES
SEAT BELT SYSTEM OPERATIONAL AND FUNCTIONAL CHECKS
NOTE: If the vehicle has been in a collision, refer to Repairs and
Inspections Required
After a Collision for additional information.
Perform the following inspection from the driver seat:
- Turn the ignition switch to the ON position. Verify proper operation of
the seat belt reminder lamp with
the belt buckled and with the belt unbuckled.
- Inspect the shoulder belt guide in order to ensure that the following
conditions are met:
- The shoulder belt guide swivels freely.
- The seat belt webbing is seated flat in the guide slot.
- The seat belt webbing does not bind.
- Verify that the seat belt buckle faces inboard and is accessible.
- Verify that the seat belt retractor units are securely attached.
- Verify that the seat belt anchor bolts are secure.
- Fully extend the seat belt webbing. Verify that the seat belt webbing
does not have any twists or tears.
- Allow the seat belt webbing to retract. Verify that the seat belt
webbing returns freely and completely
back into the retractor. If the seat belt webbing will not retract, refer to
Seat Belt Does Not Retract.
- Snap the seat belt latch plate into the buckle.
- Sharply tug on the seat belt latch plate and the buckle. Verify that the
seat belt latch plate and the buckle
remain locked when tugged.
- Push the button on the buckle:
- Verify that the seat belt latch plate releases easily from the buckle.
- Verify that the button returns to its original position.
Perform the following inspection procedure from the passenger seat.
- Verify the automatic locking retractor (ALR) feature operates properly
by performing the following
checks:
- Pull the seat belt all the way out of the retractor until it stops.
- Slowly allow the belt to retract partially, while listening for a
ratcheting sound.
- Sharply tug on the belt ensuring that the retractor lock sets and does
not allow the belt to be pulled
from the retractor.
- After performing steps 1.1 through 1.3 ensure the belt fully retracts.
- Repeat the inspection procedure steps 2 through 10 from the passengers
seat.
Perform the following steps in order to inspect the left and right rear seat
belts:
- Inspect the shoulder belt guide in order to ensure that the following
conditions are met:
- The seat belt webbing is seated flat in the guide slot.
- The seat belt webbing does not bind.
- Verify that the seat belt buckle is accessible.
- Verify that the seat belt retractor units are securely attached.
- Verify that the seat belt anchor bolts are secure.
- Fully extend the seat belt webbing. Verify that the seat belt webbing
does not have any twists or tears.
- Allow the seat belt webbing to retract. Verify that the seat belt
webbing returns freely and completely
back into the retractor.
- Snap the seat belt latch plate into the buckle.
- Sharply tug on the seat belt latch plate and the buckle. Verify that the
seat belt latch plate and the buckle
remain locked when tugged.
- Push the button on the buckle:
- Verify that the seat belt latch plate releases easily from the buckle.
- Verify that the button returns to its original position.
Emergency Locking Retractors
WARNING: Perform this test in an area clear of other vehicles or
obstructions. Do not
conduct this test on the open road. A large, empty parking lot is suitable.
Failure to observe this precaution may result in damage to the vehicle
and possible personal injury.
- Fasten the seat belts, an assistant is needed when the retractor under
test is not part of the driver seat belt.
- Accelerate the vehicle slowly to 16 km/h (10 mph) and apply the brakes
firmly.
- Verify that the seat belt locks when braking firmly.
NOTE: When performing this check, note the position that the
retractors are
mounted. Some retractors are not mounted at a zero degree inclination.
- If the belt does not lock, proceed with the following steps:
- Remove the seat belt retractor assembly.
- Tilt the seat belt retractor slowly.
Fig. 3: Checking Seat Belt Retractor Inclination
- Ensure that the seat belt webbing can be pulled from the retractor at an
inclination of 15 degrees
forward or less, from the retractors mounted position.
- Ensure the retractor cannot be pulled from the retractor at an
inclination of 45 degrees forward or
more.
- If a seat belt retractor does not operate as described, replace the
retractor assembly.

B0072 01 or B0073 01
The seat belt switch circuit is shorted to voltage.
B0072 02 or B0073 02
The seat belt switch circuit is shorted to ground.
B0072 04 or B0073 03
The seat belt switch circuit is open.
B0072 05 or B0073 05
The seat belt switch circuit is shorted to voltage or open.

Diagnostic Fault Information
Circuit/System Description
When an individual is sitting in the passenger seat the passenger presence
sensor detects the individual. A signal
to the Inflatable Restraint Sensing and Diagnostic Module indicates a person is
in the passenger seat. The
Inflatable Restraint Sensing and Diagnostic Module will turn the passenger seat
belt indicator. The passenger
seat belt switch is a 2-wire switch wired to the Inflatable Restraint Sensing
and Diagnostic Module using a
signal circuit and a low reference circuit. When the seat belt is unbuckled the
switch is closed, and when the
seat belt is buckled the switch is open. The Inflatable Restraint Sensing and
Diagnostic Module sends the status
of the passenger seat belt via a hard wire to the passenger air bag disable
indicator. After receiving the message,
the passenger air bag disable indicator controls the illumination of the
passenger seat belt indicator
Diagnostic Aids
Objects on the passenger seat can cause the passenger seat belt reminder to
be commanded on. Depending on
the sensing technology used, a conductive object (computers, MP3 players, cell
phones, diagnostic scan tool,
wires, a hand, etc.) placed on the passenger seat may cause the Passenger
Presence Detection Module to
command the passenger air bag indicator ON and/or command the passenger seat
belt indicator ON. The fasten
seat belt chime will also sound.

SEAT BELT SERVICE PRECAUTIONS
NOTE: If the vehicle has been in a collision, refer to Repairs and
Inspections
Required After a Collision for additional information.
Do not bleach or dye the seat belt webbing. Use only the following items in
order to clean the seat belt
webbing:
- A mild soap and water solution
- A soft brush or cloth
- Keep sharp edges and damaging objects away from the seat belts. Avoid
bending or damaging any part of
the seat belt buckle or the latch plate. Replace any seat belts which are
cut or damaged in any way.
- Use only the correct seat belt anchor bolts/screws and tighten the
anchor bolts/screws to the correct torque
value. Refer to Fastener Tightening Specifications. When installing seat
belt anchor bolts, start the bolt
by hand to ensure that the bolt is threaded straight.
- Some seat belts and retractors require service as a set, with service
replacement parts only. Do not attempt
to repair to individual components that require service as a set.
- Verify that the replacement part number is correct for the vehicle at
that seating position. Do not
substitute a seat belt from a different seating position.
