WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
  1. WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
  2. 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.
  3. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  4. 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.
  5. 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 parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.
  6. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  7. I1 RETRIEVE RCM DTCs

    • WARNING: Before beginning any service procedure, refer to Safety Warnings in Service Information

      REFER to Safety Belt and SRS Health and Safety Precautions in Description and Operation in Service Information .

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

    Was DTC B00B5:11, B00B5:12, B00B5:13 or B00B5:1D 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 B00B5:11 or B00B5:1D, GO to  I2. For DTC B00B5:12, GO to  I4. For DTC B00B5:13, GO to  I5.
    No  This is an intermittent fault when present as a CMDTC only. GO to  I10.
  8. I2 CHECK THE DRIVER SEAT TRACK POSITION RESTRAINTS 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 fault reported 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 Seat Track Position Sensor C356 .
    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.
    • DIAGNOSTIC TIP:  When viewing DTCs with the driver seat track position sensor disconnected, an open circuit fault is normally retrieved.

    Did the on-demand DTC change from B00B5:11 or B00B5:1D to B00B5:13? 

    Yes  GO to  I8.
    No  For DTC B00B5:11, GO to  I3. For DTC B00B5:1D, GO to  I9.
  9. I3 CHECK THE DRIVER SEAT TRACK POSITION SENSOR CIRCUIT FOR A SHORT TO GROUND

    • Ignition OFF.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C356-2

      Ground

    Is the resistance greater than 10, 000 ohms? 

    Yes  GO to  I9.
    No  REPAIR the circuit. Refer to Connector Repair Procedures for schematic and connector information. Go to  I11.
  10. I4 CHECK THE DRIVER SEAT TRACK POSITION SENSOR CIRCUIT FOR A SHORT TO VOLTAGE

    • Ignition OFF.
    • Disconnect Driver Side Airbag (Inline) C3051 .

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C356-2
      GFD134422Courtesy of FORD MOTOR COMPANY
      Ground

    Is any voltage present? 

    Yes  REPAIR the circuit. Refer to Connector Repair Procedures for schematic and connector information. Go to  I11.
    No  GO to  I9.
  11. I5 CHECK THE DRIVER SEAT TRACK POSITION RESTRAINTS 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 fault reported changes, this indicates the RCM is functioning correctly and is not the source of the fault.

    • Ignition OFF.
    • Disconnect Driver Side Airbag (Inline) C3051 .
    • Disconnect Driver Seat Track Position Sensor C356 .
    • Connect a fused jumper wire:
      Positive Lead Measurement / Action Negative Lead
      C356-1
      GFD135987Courtesy of FORD MOTOR COMPANY
      C356-2
    • Ignition ON.
    • Using a diagnostic scan tool, perform RCM self-test.
    • DIAGNOSTIC TIP:  When viewing DTCs with the driver seat track position sensor circuits shorted together, a short to ground fault is normally retrieved.

    Did the on-demand DTC change from B00B5:13 to B00B5:11? 

    Yes  REMOVE the fused jumper wire and GO to  I8.
    No  REMOVE the fused jumper wire and GO to  I6.
  12. I6 CHECK THE DRIVER SEAT TRACK POSITION SENSOR CIRCUIT FOR AN OPEN

    • Ignition OFF.

      C310B-23
      GFD134423Courtesy of FORD MOTOR COMPANY
      C356-2

    Is the resistance less than 0.5 ohm? 

    Yes  GO to  I7.
    No  REPAIR the circuit. Refer to Connector Repair Procedures for schematic and connector information. Go to  I11.
  13. I7 CHECK THE DRIVER SEAT TRACK POSITION SENSOR GROUND CIRCUIT FOR AN OPEN

    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C356-1
      GFD134423Courtesy of FORD MOTOR COMPANY
      C310B-53

    Is the resistance less than 3 ohms?
