Seat Cushion - Front: Assembly

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

All seats 

  1. Position the cushion trim cover to the cushion foam pad, attach the hook-and-loop strips and install the hog rings.

    2. Driver seat 

  2. Route the seat wire harness to the cushion frame and attach the pin-type retainer(s) as noted during removal.

    3. Passenger seats with OEM OCS or OCS system service kit 

    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 system components through the correct seat cushion support opening can cause component failure.
    CAUTION: While positioning the seat cushion frame and occupant classification system assembly, be careful not to damage any of the components. Failure to do so can result in component failure.
  3. Position the OCS components and seat wire harness through the cushion frame opening as noted during removal.
    • Feed the hose, pressure sensor, wire harness, electrical connectors and OCSM through the opening in the cushion frame.

  7. Install the pressure sensor onto the 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.

    11. All seats 

  11. Position the cushion foam pad and trim cover to the cushion frame.
  12. Install the seat track. For additional information, refer to Seat Track - Manual  or Seat Track - Power .
  13. Install the seat backrest. For additional information, refer to Seat Backrest - Front .
  14. Install the seat. For additional information, refer to Seat - Front .
  15. Repower the SRS. If the passenger seat has been serviced, do not prove out the SRS at this time.  For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .

    16. Passenger seat 

    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.
    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 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 occupant classification system module (OCSM) is above 8.0 volts and less than 18.0 volts.
    • Make sure the OCS 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 is unsuccessful, a new OCS system service kit must be installed.
  16. Carry out the OCS system reset active command.
  17. Cycle the ignition switch from ON to OFF.
    18. NOTE: The ignition switch must be cycled after the OCS system reset.
  18. Cycle the ignition switch from OFF to ON.

    19. All seats 

  19. 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.
