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 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 Supplemental Restraint System (SRS).
NOTE: Always make sure the correct Supplemental Restraint System (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 Supplemental Restraint System (SRS) component is installed, DTCs  may set.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
  1. I1 RETRIEVE RCM DTCs 
    • Ignition ON.
    • Using a scan tool, perform RCM  self-test to retrieve DTCs  .

    Was DTC B0050:11, B0050:12, B0050:13 or B0050:1D 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  B0050:11 or B0050:1D, GO to I2  .

      For DTC  B0050:12, GO to  I4.

      For DTC  B0050:13, GO to  I5.

    2. No  : This is an intermittent fault when present as a 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.
    • 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 Driver Safety Belt Buckle Switch C3247  .
    • Ignition ON.
    • Using a scan tool, perform RCM  self-test to retrieve DTCs  .
    • DIAGNOSTIC TIP:  When viewing DTCs  with the driver safety belt buckle switch disconnected, an open circuit fault is normally retrieved.

    Did the on-demand DTC change from B0050:11 or B0050:1D to B0050:13? 

    1. Yes  : GO to  I8.
    2. No  : For DTC  B0050:11, GO to I3  .

      For DTC  B0050:1D, GO to  I9.

  3. I3 CHECK THE DRIVER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR A SHORT TO GROUND 

    Is the resistance greater than 10, 000 ohms? 

    1. Yes  : GO to  I9.
    2. No  : REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for connector information.

      GO to  I11.

  4. I4 CHECK THE DRIVER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR A SHORT TO VOLTAGE 

    Is any voltage present? 

    1. Yes  : REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for connector information.

      GO to  I11.

    2. No  : GO to  I9.
  5. I5 CHECK THE DRIVER 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.

    Did the on-demand DTC change from B0050:13 to B0050:11? 

    1. Yes  : REMOVE the fused jumper wire and GO to  I8.
    2. No  : REMOVE the fused jumper wire and GO to I6  .
  6. I6 CHECK THE DRIVER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR AN OPEN 

    Is the resistance less than 0.5 ohm? 

    1. Yes  : GO to I7  .
    2. No  : REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for connector information.

      GO to  I11.

  7. I7 CHECK THE DRIVER SAFETY BELT BUCKLE SWITCH RETURN CIRCUIT FOR AN OPEN 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C3247-4  OHM C310B-53 

    Is the resistance less than 3 ohms? 

    1. Yes  : GO to  I9.
    2. No  : REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for connector information.

      GO to  I11.

  8. I8 CONFIRM THE DRIVER SAFETY BELT BUCKLE SWITCH FAULT 
    NOTE: Make sure all SRS  components and the RCM  electrical connectors are connected before carrying out the self-test. If not, DTCs  will be recorded.

    Was the original DTC retrieved on-demand during self-test? 

    1. Yes  : INSTALL a new driver safety belt buckle and pretensioner. REFER to SAFETY BELT BUCKLE - FRONT . GO to  I11.
    2. No  : In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test  . GO to  I10.
  9. I9 CONFIRM THE RCM FAULT 
    NOTE: Make sure all SRS  components and the RCM  electrical connectors are connected before carrying out the self-test. If not, DTCs  will be recorded.

    Was the original DTC retrieved on-demand during self-test? 

    1. Yes  : CHECK OASIS  for any applicable TSBs  . If a TSB  exists for this concern, discontinue this test and follow TSB  instructions. If no TSBs  address this concern, INSTALL a new RCM  . Refer to RESTRAINTS CONTROL MODULE (RCM) . GO to  I11.
    2. No  : In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test  . GO to I10  .

    Was DTC B0050:11, B0050:12, B0050:13 or B0050:1D 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  B0050:12, GO to  I4.

      For DTC  B0050:13, GO to  I5.

    2. No  : The fault is not present and cannot be recreated at this time. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test  . GO to I11  .
  11. I11 CHECK FOR ADDITIONAL SRS DTCs 

    Are any RCM and/or OCSM DTCs retrieved on-demand during self-test? 

    1. Yes  : Do not clear any DTCs  until all DTCs  have been resolved. REFER to the appropriate DTC CHART in this information for pinpoint test direction.
