Sensor - Resistive Occupancy - Front Seat - LH (Model 3 Seat) (Remove & Replace)

Correction Code 20202122

Warning IconA warning icon, calling your attention to a possibly risky situation
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

  1. Remove the driver seat. See Seat Assembly - 1st Row - LH (Remove and Install).
  2. Remove the inboard side shield:
    1. Release the front clip that attaches the inboard side shield to the seat inner seat rail.
    2. Release the rear portion of the inboard side shield from the inner seat rail, and then rotate the side shield upwards.
    3. Pass the buckle out through the slot on the inboard side shield, and then remove the inboard side shield from the seat.
  3. Remove the outboard side shield:
    1. Remove the bolt that attaches the driver seat outboard side shield to the seat frame.
      Tip:
    2. Pull the driver seat outboard side shield away from the seat frame to release the clip that attaches the side shield to the center of the seat frame.
    3. Disconnect the seat switch connector.
    4. Slide the driver seat outboard side shield rearwards to release the clips that attach the side shield to rear of the seat frame, and then remove the outboard side shield from the seat.
  4. Disconnect the electrical harness from the resistive occupancy sensor connector.
  5. Release the clip that attaches the resistive occupancy sensor to the seat underside, and then separate the sensor from the seat underside.
  6. 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.

  7. Lift the front of the driver seat cushion foam trim, releasing clips and--if present--velcro strips, until the resistive occupancy sensor is exposed.

  8. While wearing cut-resistant gloves, carefully use a razor blade to separate the resistive occupancy sensor from the driver seat cushion foam.

    CAUTION
    Take care to remove as little foam as possible.
  9. 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.

    CAUTION
    While removing the harness, take care not to damage the foam.

Installation

Installation procedure is the reverse of removal, except for the following:

  1. 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.

    CAUTION
    While installing the harness, take care not to damage the foam.
