Occupant Classification Sensor: Installation

All seats 

    WARNING: Install a new occupant classification sensor (OCS) system service kit as a complete assembly. Never install only part of the kit components. Failure to follow this instruction may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a crash.
    CAUTION: Failure to route the seat occupant sensor components through the correct seat cushion support opening may cause component failure.
    CAUTION: While positioning the seat cushion pan and occupant classification sensor assembly, be careful not to damage any of the components. Failure to do so may result in component failure.
    NOTE: If the original equipment OCS system is not being installed, install an OCS system using service kit all parts in the kit.
  1. Position the OCSM to the seat cushion frame.
    • Feed the hose, pressure sensor, wire harness, electrical connector and the OCSM through the seat cushion frame assembly.

    NOTE: Make sure the OCSM is properly secured to the bracket.
  2. Position the OCSM onto the seat cushion frame bracket and install new rivets.
  3. Bend the retaining tab back on the pressure sensor bracket.

    Seats with an OCS system service kit  

  4. Position the OCS service kit foam pad and attach the 2 pin-type retainers to the seat cushion frame assembly.

    5. Seats with a production OCS system 

  5. Attach the 2 OCS system bladder pin-type retainers to the seat cushion frame assembly.

    6. All seats 

  6. Attach all the seat wire harness routing clips and electrical connector retainers to the cushion frame assembly.

    7. Seats with power 

  7. Connect the seat control switch electrical connector to the side trim cover.

    8. All seats 

  8. Install the pressure sensor onto the seat cushion frame bracket, making sure the retaining tab is completely engaged.
    • When installed correctly, an audible click will be heard and the pressure sensor will not be able to be removed from its bracket without disengaging the retaining tab.

  10. Attach the seat cushion trim cover J-clips and the pin-type retainer to the seat cushion frame assembly.
  11. Install the seat track. For additional information, refer to SEATING .
  12. Install the seat backrest. For additional information, refer to SEATING .
  13. Install the passenger seat into the vehicle. For additional information, refer to SEATING .
  14. Repower the SRS. Do not prove out the SRS at this time.  For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering .
    15. WARNING: Make sure the front passenger seat repair is complete, the seat and all attached components (head restraint, seat side shield, etc.) are correctly assembled, and the seat is correctly installed to the vehicle before carrying out the System Reset. Failure to follow these instructions may result in incorrect operation of the occupant classification sensor (OCS) system and increases the risk of serious personal injury or death in a crash.
    CAUTION: To prevent system failure, it is necessary to carry out the occupant classification sensor (OCS) system reset of the OCS system when a front passenger seat cushion is disassembled, a new trim cover installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset command.
    CAUTION: To prevent system failure, the following precautions must be taken before carrying out the occupant classification sensor (OCS) system reset:
    • Make sure the voltage to the OCSM is above 8.0 volts and less than 18.0 volts.
    • Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C (97°F) when initiating the OCS system reset process. If the vehicle has been exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept at a temperature within the limits, 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
    • Make sure nothing is present on the passenger seat before carrying out the OCS system reset and nothing is placed on the seat during the process.
    • Make sure a minimum 8-second time period has passed after cycling the ignition switch ON before the carrying out the OCS system reset process.
    NOTE: If the first attempt to carry out the occupant classification sensor (OCS) system reset is unsuccessful, a second attempt must be made. If the second attempt to carry out the OCS system reset is unsuccessful, a new OCS system service kit must be installed.
  15. Carry out the OCS system reset active command.
  16. Cycle the ignition switch from ON to OFF.
    17. NOTE: The ignition switch must be cycled after the OCS system reset.
  17. Cycle the ignition switch from OFF to ON.
  18. Prove out the SRS as follows:

    Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag warning indicator will:

    - fail to light.

    - remain lit continuously.

    - flash at a 5Hz rate (RCM not configured).

    The air bag warning indicator might not light until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired.

    Clear all continuous DTCs from the RCM using a scan tool.

    19. NOTE: A prepaid return postcard is provided with a new OCS system service kit. The serial number for the new part and the vehicle identification number (VIN) must be recorded and sent to Ford Motor Company.
  19. If a new OCS system service kit was installed, fill out the necessary information on the OCS system traceability card and return it along with the complete inoperative OCS system to Ford Motor Company.
    • When returning the inoperative OCS system include: seat cushion foam pad, bladder, OCSM, pressure sensor (transducer), hose, electrical connectors and wire harness (service part OCS only).
