  Q: How to arm and disarm the air bag system on Lincoln Mark LT?

  A:

  Turning the Ignition Switch from OFF to ON position enables air bag system arming and disarming under the condition of connected SRS components or installed restraint system diagnostic tools. A continuous illumination of the air bag indicator should last about 6 seconds before it shuts down. The air bag indicator fails to illuminate but it stays lit continuously and can flash following approximately 30 seconds after ignition because that time is when the restraints control module completes its tests. That warning sound comprises five series of five beeps when the air bag indicator fails to work and an SRS fault is detected. This signals the need to fix the air bag indicator before advancing diagnosis can start.

  Q: How to Inspect and Repair the Air Bag Supplemental Restraint System (SRS) After a Collision on Lincoln Mark LT?

  A:

  The inspection along with repair of Supplemental Restraint System (SRS) remains crucial after collisions to maintain vehicle safety and meet regulatory requirements. The vehicle requires removal of the diagnostic tool from the restraint system before driving because this prevents injuries while avoiding traffic rule violations. The diagnostic tools need removal from every SRS and seat system diagnosis or repair process before starting vehicle operation. A complete replacement of all deployed air bag modules and pretensioners along with new restraints impact sensors and restraints control module is required in cases where deployable devices have activated or if RCM shows DTC B1231 (Crash Data Memory Full). Post-repair process demands the elimination of all stored DTCs from necessary modules. A repair for vehicles with occupant classification sensor (OCS) systems needs to examine passenger side floorpan damage before installing new rail type OCS rails along with new seat tracks equipped with weight sensor bolt types. Bladder type OCS modules do not register DTC B1231 after deployment because this diagnostic code requires the RCM to record it. Installation of a new Clock Spring is mandatory when the driver air bag module has deployed while all impact sensor mounting points with hardware damage need either repair or replacement. When pretensioners activate during deployment the vehicle requires replacement of all front safety belt components including retractors and buckles along with height adjusters. The inspection of the vehicle requires examination of the Steering Column and instrument panel knee bolsters as well as seats safety belts and braces followed by installation of new components and essential repairs.
