The belt tension sensor cannot be repaired and, if
faulty or damaged, the entire passenger side front
seat belt and retractor unit must be replaced (Refer

OPERATION
The belt tension sensor is designed to sense the
relative cinch load applied to the passenger side front
seat belt, which provides a logic input to the micro-
processor of the Occupant Classification Module
(OCM). When a load is applied to the seat belt, the
changes in the load are measured by the belt tension
sensor through the seat belt lower anchor. As the
load changes, the circuitry of the belt tension sensor
changes the output voltage of the sensor.
The belt tension sensor receives a nominal five
volts and a ground from the OCM. The OCM then
monitors the belt tension sensor output voltage.
WARNING: Do not connect the battery before per-
forming the OCS Verification Test using the scan
tool and the appropriate diagnostic information.
Personal injury or death may occur.
For further diagnosis and testing of the belt ten-
sion sensor, the OCM, and related occupant classifi-
cation system components, use a scan tool and the
appropriate diagnostic information.
CHILD RESTRAINT ANCHOR
DESCRIPTION
This vehicle is equipped with a Lower Anchors and
Tether for CHildren, or LATCH child restraint
anchorage system. The LATCH system provides for
the installation of suitable child restraints in certain
seating positions without using the standard equip-
ment seat belt provided for that seating position. The
second seat in these models are equipped with a
fixed-position child restraint upper tether anchor and
child restraint lower anchors. The third seat is
equipped with only a fixed-position child restraint
upper tether anchor.
There are two lower anchors for each rear second
row seating position (Fig. 6). These anchors are
welded to the seat cushion frame. They are each
accessed from the front of their respective seats, at
each side where the seat back meets the seat cush-
ion. These lower anchors cannot be adjusted or
repaired and, if faulty or damaged, the seat must be
replaced as a unit. Each second row seating position
has a child restraint upper tether anchor as well. It
is located in the middle of the seat cushion in the
rear of the seat (Fig. 7). The left third row seating
position has an integral upper tether anchor in the
middle rear seat back (Fig. 8). If any of these are
damaged during an impact event, the affected seat
component (seat back or seat cushion) must be
replaced. They are not serviceable.
