Sensor - Resistive Occupancy - Front Seat - LH (Model 3 Seat) (Remove & Replace)
Correction Code 20202122
Warning
Make sure 12V/LV power has
been disconnected for at least 1 minute before disconnecting the electrical harness from
Supplementary Restraint System (SRS) components, such as Restraint Control Module, sensors,
airbags, etc. Failure to do so can result in unintended safety system behaviors. For more
information on SRS precautions, see .
Note
This procedure applies only to the
resistive pad occupancy sensor (i.e., Seat Belt Reminder). RH front seats in North
America and South Korea use the Occupant Classification System (OCS) sensor, which
is not currently serviceable.
Removal
- Remove the driver seat. See Seat Assembly - 1st Row - LH (Remove and Install).
-
Remove the inboard side
shield:
-
Remove the outboard side shield:
- Disconnect the electrical harness from the resistive occupancy sensor connector.
- Release the clip that attaches the resistive occupancy sensor to the seat underside, and then separate the sensor from the seat underside.
-
Release the clips (x3) that
attach the seat cushion foam to the seat cushion frame at the front,
inboard, and outboard sides.
Tip: Use an angled pick to pull the retaining clips down and away from the seat frame.
-
Lift the front of the driver
seat cushion foam trim, releasing clips and--if present--velcro strips,
until the resistive occupancy sensor is exposed.
-
While wearing cut-resistant
gloves, carefully use a razor blade to separate the resistive occupancy
sensor from the driver seat cushion foam.
WarningAlways wear cut-resistant gloves when using cutting tools.CAUTIONTake care not to damage the sensor harness, seat trim, or other surrounding components with the razor blade.CAUTIONTake care to remove as little foam as possible.
-
From the underside of the
cushion, carefully route the resistive occupancy sensor harness up through
the top of the cushion, and then remove the sensor from the cushion.
CAUTIONWhile removing the harness, take care not to damage the foam.
Installation
Installation procedure is the reverse of removal, except for the following:
-
Position the resistive
occupancy sensor on top of the driver seat cushion foam, and then route the
sensor harness through the harness opening in the foam.
CAUTIONWhile installing the harness, take care not to damage the foam.
-
Peel the protective backing
off of the resistive occupancy sensor, exposing the adhesive, and then
install the sensor on top of the foam.
NoteAlign the sensor with the indentations on the foam.
