Remove

  1. Remove the passenger seat cushion trim. See Trim - Cushion - Driver Seat (Remove and Replace).
  2. Remove the casing from the seat occupancy sensor harness.
  3. Use an heat gun to heat the occupancy sensor until it reaches to 85 ℃.
    Informational PurposesAn informational icon, calling your attention
    Note
    Set the heat gun temperature to 100–300 °C. Hold the heat gun approximately 40 mm from the sensor surface and gently heat to reduce the resin viscosity.

    Note
    Align the sensor with the indentations on the foam.
  3. Install the passenger seat cushion trim. See Trim - Cushion - Driver Seat (Remove and Replace).
  4. If servicing the front passenger seat in a North American vehicle:
    1. Remove all objects from the front passenger seat before beginning calibration.
    2. On the vehicle touchscreen, touch Controls (Vehicle Icon) > Software and check the vehicle firmware version. If the vehicle firmware is 2023.2.11 or newer, perform a software reinstall. See Software Reinstall - Touchscreen. If the vehicle firmware is not 2023.2.11 or newer, update the vehicle firmware. See Software Update.
    3. Locally connect a laptop with Toolbox 3 to the vehicle. See Toolbox (Connect and Disconnect).
    4. Unlock the vehicle gateway. See Gateway (Unlock).
    5. In Toolbox, click on the Actions tab, and then search for "OCS".
    6. Run the PROC_OCS1P_SELF-CALIBRATIONvia Service Mode Plus:Safety & Restraints ➜ Seats ➜ OCS1P Self Capacitance Calibrationvia Toolbox:(link) routine.
    7. Click on the Actions tab, and then search for "Seat calibration".
    8. Run the PROC_VCRIGHT_SEAT-CALIBRATEvia Service Mode:Low Voltage ➜ Seats ➜ Calibratevia Toolbox:(link) routine.
    9. Disconnect Toolbox and remove the laptop from the vehicle.
