Ford Fusion: Supplemental Restraint System / Battery Energy Control Module B (BECMB). Removal and Installation

Removal

  WARNING: The following procedure prescribes critical repair steps required for correct restraint system operation during a crash. Follow all notes and steps carefully. Failure to follow step instructions may result in incorrect operation of the restraint system and increases the risk of serious personal injury or death in a crash.

NOTE: Removal steps in this procedure may contain installation details.

1. NOTE: This step is only necessary when installing a new component.

   NOTE: The PMI process must begin with the current BECMB installed. If the current BECMB does not respond to the diagnostic scan tool, the tool may prompt for As-Built Data as part of the repair.

   Using a diagnostic scan tool, begin the PMI process for the BECMB following the on-screen instructions.
   

1.   WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Ignition must remain OFF until repair is complete. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

   If a SRS fault is present, continue to Step 3. Otherwise, turn the ignition off, wait at least one minute and continue to Step 4.
   

1. Depower the SRS.
   Refer to: Supplemental Restraint System (SRS) Depowering and Repowering (501-20B Supplemental Restraint System, General Procedures).
   

1. Remove the floor console.
   Refer to: Floor Console (501-12 Instrument Panel and Console, Removal and Installation).
   

1. 1. Disconnect the electrical connector.
      
   2. Remove the nuts.
      Torque: 19 lb.in (2.2 Nm)
   3. Remove the BECMB and bracket.
      

1. Remove the pin-type retainers and separate the BECMB from the bracket.
   

Installation

1. To install, reverse the removal procedure.
   

1. If the SRS was depowered, repower the SRS. For a new BECMB, do not prove out the SRS at this time.
   Refer to: Supplemental Restraint System (SRS) Depowering and Repowering (501-20B Supplemental Restraint System, General Procedures).
   

1. NOTE: This step is only necessary when installing a new BECMB.

   Using a diagnostic scan tool, complete the PMI process for the BECMB following the on-screen instructions.
   

1. • If a new BECMB was installed, prove out the SRS as follows: Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back to ON and monitor the airbag warning indicator with the airbag modules installed. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a SRS fault is present, the airbag warning indicator either fails to light, remains lit continuously or flashes.
     
   • The flashing might not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. This is the time required for the RCM to complete the testing of the SRS. If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults.
