Removal and Installation

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an airbag module. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: To reduce the risk of personal injury, do not use any memory saver devices.
WARNING: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
CAUTION: It is necessary to rezero the occupant classification sensor (OCS) system when a front passenger seat cushion is disassembled, a new trim cover is installed, or an OCS service kit is installed. A diagnostic tool is used to trigger the active command to carry out rezeroing of the OCS system.
NOTE: If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the supplemental restraint system (SRS) must be depowered. 
NOTE: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    All seats 

  1. Position the seat to access all the seat track-to-floor pan bolts and the safety belt anchor.
  2. Depower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures portion of SUPPLEMENTAL RESTRAINT SYSTEM .

  16. Install the seat. For additional information, refer to SEAT - FRONT .
  17. Repower the SRS. 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 .

    18. Passenger seat 

    WARNING: Do not separate components.
    CAUTION: It is necessary to rezero the OCS system when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS service kit is installed. A diagnostic tool is used to trigger the active command to carry out rezeroing of the OCS system.
    CAUTION: Make sure the seat is completely assembled before rezeroing.
    CAUTION: The following precautions must be taken before rezeroing the OCS system.
    • Make sure the OCS system components are connected and no faults are present.
    • Make sure the OCS system is not at a temperature below 0°C (32°F) or above 45°C (113°F) when initiating the rezeroing 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, 0°C to 45°C (32°F to 113°F) for a minimum of 30 minutes.
    • Make sure nothing is present on the passenger seat before rezeroing and nothing is placed on the seat during the rezeroing process.
    • Make sure a minimum 8-second time period has passed after cycling the ignition switch ON before the rezeroing process.
    NOTE: For best results in rezeroing, the OCS system should be at or near room temperature, 10°C to 29°C (50°F to 85°F).
    NOTE: If the first attempt to rezero the OCS system is unsuccessful, a second attempt must be made.
  18. Rezero the occupant classification sensor.
    • With the front passenger seat empty, use a diagnostic tool to trigger the active command and rezero the OCS.
    19. NOTE: The ignition switch must be cycled after rezeroing the OCS system.
  19. Cycle the ignition switch from ON to OFF.

    20. All seats 

  20. Prove out the supplemental restraint system (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 indicator with the air bag modules installed. The air bag indicator will light continuously for approximately 6 seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will:

    • fail to light.
    • remain lit continuously.
    • flash.

    The flashing might not occur 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 restraints control module (RCM) to complete the testing of the SRS. If the air bag 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 indicator and any SRS fault discovered must be diagnosed and repaired.

    Clear all continuous DTCs from the restraints control module using a diagnostic tool.
