Pinpoint Test A : B0052:11, B0052:12, B0052:13 And B0052:1D

WARNING: Do not handle, move or change the original horizontal mounting position of the Restraints Control Module (RCM) while the Restraints Control Module (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.
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 the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. A1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS) 

    Was DTC B0052:11, B0052:12, B0052:13 or B0052:1D retrieved on-dem and during self-test? 

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

      For DTC B0052:11 or B0052:1D, GO to A2

      For DTC B0052:12, GO to  A4

      For DTC B0052:13, GO to  A5

    2. No:  This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to  A10
  2. A2 CHECK THE PASSENGER SEATBELT SENSOR DTC (DIAGNOSTIC TROUBLE CODE) 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.
    • Depower the SRS.

      REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .

    • Disconnect Passenger Safety Belt Buckle C3238.
    • Repower the SRS. Do not prove out the SRS at this time.

      REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .

    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.
    • DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger safety belt buckle disconnected, an open circuit fault is normally retrieved. Because the passenger safety belt buckle switch shares a connector with the Belt Tension Sensor (BTS), a Belt Tension Sensor (BTS) circuit fault will also be present in the OCSM.

    Did the on-demand DTC change from B0052:11 or B0052:1D to B0052:13? 

    1. Yes:  GO to  A8
    2. No:  For DTC B0052:11, GO to A3

      For DTC B0052:1D, GO to  A9

  3. A3 CHECK THE PASSENGER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR A SHORT TO GROUND 

    Click to display connectors 

    Positive Lead Measurement / Action Negative Lead
    C3238-5 Ω -

    Is the resistance greater than 10, 000 ohms? 

    1. Yes:  GO to  A9
    2. No:  REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

      GO to  A11

  4. A4 CHECK THE PASSENGER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR A SHORT TO VOLTAGE 

    Click to display connectors 

    Positive Lead Measurement / Action Negative Lead
    C3238-5
    G08101478
    		 -

    Is any voltage present? 

    1. Yes:  REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

      GO to  A11

    2. No:  GO to  A9
  5. A5 CHECK THE PASSENGER SEATBELT SENSOR DTC (DIAGNOSTIC TROUBLE CODE) 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.

    Click to display connectors 

    Positive Lead Measurement / Action Negative Lead

    		 C3238-6
    • Repower the SRS. Do not prove out the SRS at this time.

      REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .

    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.
    • DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the passenger safety belt buckle switch circuits shorted together, a short to ground fault is normally retrieved. Because the passenger safety belt buckle switch shares a connector with the Belt Tension Sensor (BTS), a Belt Tension Sensor (BTS) circuit fault will also be present in the OCSM.

    Did the on-demand DTC change from B0052:13 to B0052:11? 

    1. Yes:  REMOVE the fused jumper wire and GO to  A8
    2. No:  REMOVE the fused jumper wire and GO to A6
  6. A6 CHECK THE PASSENGER SAFETY BELT BUCKLE SWITCH CIRCUIT FOR AN OPEN 

    Click to display connectors 

    Positive Lead Measurement / Action Negative Lead
    C310B-25 Ω C3238-5

    Is the resistance less than 0.5 ohm? 

    1. Yes:  GO to A7
    2. No:  REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

      GO to  A11

  7. A7 CHECK THE PASSENGER SAFETY BELT BUCKLE SWITCH GROUND CIRCUIT FOR AN OPEN 
    • Measure:

    Click to display connectors

    1. Yes:  GO to  A9
    2. No:  REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

      GO to  A11

  8. A8 CONFIRM THE PASSENGER 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, Diagnostic Trouble Codes (DTCs) will be recorded.

      • inspect wire harness for any damaged, pinched, cut or pierced wires.
      • inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation.

        REFER to: Restraints Control Module (RCM) .

      • repair any concerns found.

        Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

    • Connect RCM C310A and C310B (if previously disconnected).

      REFER to: FRONT SAFETY BELT BUCKLE .

      GO to  A11

    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  A10
  9. A9 CONFIRM THE RCM (RESTRAINTS CONTROL MODULE) FAULT 
    NOTE: Make sure all SRS components and the RCM electrical connectors are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.
    • Ignition OFF.
    • Depower the SRS.

      REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .

    • Using a diagnostic scan tool, perform RCM self-test.

    Was the original DTC retrieved on-dem and during self-test? 

    1. Yes:  CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RCM.

      REFER to: Restraints Control Module (RCM) .

      GO to  A11

    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 A10
  10. A10 CHECK FOR AN INTERMITTENT FAULT 

    Was DTC B0052:11, B0052:12, B0052:13 or B0052:1D retrieved on-dem and during self-test?
