WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy and cause serious personal injury or death.
WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS  components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS  .
NOTE: Always make sure the correct SRS  component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS  component is installed, DTCs  may set.
NOTE: The SRS  must be fully operational and free of faults before releasing the vehicle to the customer.
  1. BK1 RETRIEVE RCM DTCs 
    • Ignition ON.
    • Using a scan tool, perform RCM  self-test to retrieve DTCs  .

    Was DTC B140D:11, B140D:12, B140D:13 or B140D:1D retrieved on-demand during self-test? 

    1. Yes  : This fault cannot be cleared until it is corrected and the DTC  is no longer retrieved on-demand during self-test.

      For DTC  B140D:11 or B140D:1D, GO to BK2  .

      For DTC  B140D:12, GO to  BK4.

      For DTC  B140D:13, GO to  BK5.

    2. No  : This is an intermittent fault when present as a CMDTC  only. GO to  BK10.
  2. BK2 CHECK THE SECOND ROW PASSENGER SIDE SEATBELT SENSOR DTC FOR A FAULT STATUS CHANGE (SHORT TO GROUND OR CURRENT OUT OF RANGE INDICATED) 
    • WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

      Ignition OFF.

    • Disconnect Second Row Right Safety Belt Buckle Switch C3647  .
      • Remove 5 screws and the seat track inboard inner and outer covers.
      • Detach the cushion cover front and inboard retainers.
      • Lift the cushion cover and foam pad.
    • Ignition ON.
    • Using a scan tool, perform RCM  self-test to retrieve DTCs  .
    • DIAGNOSTIC TIP:  When viewing DTCs  with the second row right safety belt buckle switch disconnected, an open circuit fault is normally retrieved.

    Did the on-demand DTC change from B140D:11 or B140D:1D to B140D:13? 

    1. Yes  : GO to  BK8.
    2. No  : For DTC  B140D:11, GO to BK3  .

    2. No  : GO to  BK9.
  5. BK5 CHECK THE SECOND ROW PASSENGER SIDE SEATBELT SENSOR DTC FOR A FAULT STATUS CHANGE (OPEN INDICATED) 
    NOTE: This pinpoint test step attempts to change the fault reported by the RCM  by inducing a different fault condition. If the reported fault changes, this indicates the RCM  is functioning correctly and is not the source of the fault.
    • WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.

      Ignition OFF.

      Positive Lead Measurement/Action Negative Lead
      C3647-1  FUSED JUMPER WIRE C3647-2 
    • Ignition ON.
    • Using a scan tool, perform RCM  self-test to retrieve DTCs  .
    • DIAGNOSTIC TIP:  When viewing DTCs  with the second row right safety belt buckle switch circuits shorted together, a short to ground fault is normally retrieved.
