WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. 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 probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of 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: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
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 Supplemental Restraint System (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 the 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. I1 RETRIEVE RCM DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM  .

    Was DTC B0050:11, B0050:12, B0050:13 or B0050:1D retrieved on-demand during self-test? 

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

      For DTC B0050:11 or B0050:1D, GO to I2  .

      For DTC B0050:12, GO to  I4.

      For DTC B0050:13, GO to  I5.

    • No  : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to  I10.
  2. I2 CHECK THE DRIVER SEATBELT SENSOR DTC FOR A FAULT STATUS CHANGE (SHORT TO GROUND OR CURRENT OUT OF RANGE 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.
    • Ignition OFF.
      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.
    • Disconnect: Driver Safety Belt Buckle Switch C3065  .
