PINPOINT TEST BL : B1413:11 and B1413:93

  1. 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.
  2. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  3. 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. 
  4. 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.
  5. NOTE: Do not probe any impact sensor. The impact sensor cannot be tested using a multi-meter.
  6. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

  7. BL1 RETRIEVE RCM DTCs

    • Ignition ON.
    • Using a scan tool, perform RCM self-test to retrieve DTCs.

    Was DTC B1413:11 or B1413:93 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 B1413:11, GO to  BL2. For DTC B1413:93, GO to  BL5.

  8. BL2 CHECK THE DRIVER FRONTAL RESTRAINTS SENSOR DTC FOR A FAULT STATUS CHANGE (SHORT TO GROUND 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.
    • Ignition ON.
    • Using a scan tool, perform RCM self-test to retrieve DTCs.

    Did the on-demand DTC change from B1413:11 to B1413:93?

    • Ignition OFF.
    • Inspect LH Front Impact Severity Sensor C1465 to be fully seated and locked. Seat and lock the connector as necessary.
    • Ignition ON.
    • Using a scan tool, perform RCM self-test to retrieve DTCs.

    Was DTC B1413:93 retrieved on-demand during self-test? 

    Yes  GO to  BL6.
    No  The fault has been corrected. GO to  BL11.

  12. BL6 CHECK THE LH FRONT IMPACT SEVERITY SENSOR FEED CIRCUIT FOR A SHORT TO VOLTAGE (NO OPERATION INDICATED)

    • Ignition OFF.
    • Ignition ON.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C1465-1
      GFD33595Courtesy 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  BL11.
    No  GO to  BL7.

  13. BL7 CHECK THE LH FRONT IMPACT SEVERITY SENSOR CIRCUITS FOR AN OPEN

    • Ignition OFF.
    • Measure:
      Positive Lead Measurement / Action Negative Lead
      C310A-17
      GFD33596Courtesy of FORD MOTOR COMPANY

      		 C1465-2

    Are the resistances less than 0.5 ohm? 

    Yes  GO to  BL8.
    No  REPAIR the circuit(s). Refer to CONNECTOR REPAIR PROCEDURES for schematic and connector information. GO to  BL11.

  14. BL8 CHECK THE DRIVER FRONTAL RESTRAINTS SENSOR DTC FOR A FAULT STATUS CHANGE (NO OPERATION 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.
    • Connect a fused jumper wire:

    Yes  REMOVE the fused jumper wire and INSTALL a new LH front impact severity sensor. REFER to Front Impact Severity Sensor . GO to  BL11.
    No  REMOVE the fused jumper wire and GO to  BL9.

  15. BL9 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.
    • Ignition OFF.
    • Prior to reconnecting any previously disconnected SRS component:
      • inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
      • inspect wire harness for any damaged, pinched, cut or pierced wires.
      • inspect RCM C310A and C310B CPA lever/lock for correct operation. Refer to Restraints Control Module (RCM) .
      • repair any concerns found. Refer to CONNECTOR REPAIR PROCEDURES for schematic and connector information.
    • Connect LH Front Impact Severity Sensor C1465 (if previously disconnected).
    • Ignition ON.
    • Using a scan tool, perform RCM self-test to retrieve DTCs.

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

    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  BL11.
    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  BL10.

  16. BL10 CHECK FOR AN INTERMITTENT FAULT

    • Ignition OFF.
    • Inspect for the following:
      • Inspect harness and component connectors for loose or spread terminals and loose or frayed wire connections at terminals.

      • Inspect RCM C310A and C310B CPA lever/lock for correct operation. Refer to Restraints Control Module (RCM) .
      • Repair any concerns found. Refer to CONNECTOR REPAIR PROCEDURES for schematic and connector information.
    • Connect all previously disconnected component(s)/connector(s).
    • Ignition ON.
    • Using a scan tool, perform RCM self-test to retrieve DTCs.

    Was DTC B1413:11 or B1413:93 retrieved on-demand during the 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 B1413:11, GO to  BL2. For DTC B1413:93, GO to  BL5.
    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 BL11.

  17. BL11 CHECK FOR ADDITIONAL SRS DTCs

    • 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.

    • Reconnect all SRS components (if previously disconnected).
    • Ignition ON.
      NOTE: When selecting Restraints from the Self-Test menu, DTCs are retrieved from the RCM and OCSM.
    • Using a scan tool, perform

      Restraints  self-test to retrieve DTCs.

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

    Yes  Do not clear any DTCs until all DTCs have been resolved. REFER to the appropriate DTC Chart in this service information for pinpoint test direction.
    No  CLEAR all RCM and OCSM CMDTCs. PROVE OUT the SRS. The repair is complete. RETURN the vehicle to the customer.
