Sensor - Resistive Occupancy - Front Seat - LH (Remove and Replace)

Correction code 20202102 0.60 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so.NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.

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 Airbag and Supplementary Restraint System (SRS) Precautions.
Informational PurposesAn informational icon, calling your attention
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.
  • 2023-05-18: Added a video at Step 9 in Removal part to avoid damage to components and/or personal injury.

Remove

  1. Remove the driver seat. See Seat Assembly - 1st Row - LH (Remove and Replace).
  2. Place the driver seat on a clean working surface.
  3. Remove the driver seat outboard side shield. See Side Shield - Outboard - Driver Seat (Remove and Replace).
  4. Remove the driver seat inboard side shield. See Side Shield - Inboard - Driver Seat (Remove and Replace).
  5. Disconnect the heater pad connector, then remove it from the seat underside.
  6. Disconnect the electrical harness from the resistive occupancy sensor connector.
  7. Release the clip that attaches the resistive occupancy sensor to the seat underside, and then separate the sensor from the seat underside.
  8. 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.

    CAUTION
    Take care to remove as little foam as possible.
  11. 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.

Install

  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.

    Note
    Align the sensor with the indentations on the foam.
  3. Pull the driver seat cushion foam trim over the foam, installing all clips and--if present--velcro strips.

  4. Install the heater pad connector to the seat underside, then connect it.
  5. Position the resistive occupancy sensor harness on the support bracket, and then install the clip that attaches the harness to the bracket.
  6. Connect the resistive occupancy sensor connector to the electrical harness.
  7. Install the clips (x3) that attach the seat cushion foam to the seat cushion frame at the front, inboard, and outboard sides.
