Pinpoint Test W: B11D8:12 And B11D8:14

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: Install new components only when directed to do so in the pinpoint test.
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) 
    • Ignition ON.
    • Using a diagnostic scan tool, perform the RCM  self-test to retrieve Diagnostic Trouble Codes (DTCs).

    Was DTC B11D8:12 or B11D8:14 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 the self-test. For DTC  B11D8:14, GO to  A2 For DTC  B11D8:12, GO to  A5
    2. No  : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to  A8
  2. A2 CHECK THE EVENT NOTIFICATION SIGNAL CIRCUIT FOR AN OPEN 

    Are the resistances less than 3 ohms? 

    1. Yes  : GO to  A3
    2. No  : REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES EXCEPT ELECTRIC--> for schematic and connector information.

      GO to  A9

  3. A3 CHECK THE EVENT NOTIFICATION SIGNAL CIRCUIT FOR A SHORT TO GROUND 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C2280C-51  OHM Ground

    Is the resistance greater than 10, 000 ohms? 

    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 BCM  .

      REFER to: BODY CONTROL MODULE (BCM) .

      GO to  A4

    2. No  : REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES EXCEPT ELECTRIC--> for schematic and connector information.

      GO to  A9

  4. A4 CONFIRM THE BCM (BODY CONTROL MODULE) REPAIR 
    • Disconnect BCM C2280C  .
    • Prior to reconnecting each previously disconnected component:
    • Connect RCM C310A  and C310B  .
    • Connect BCM C2280C  .
    • 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, clear all RCM  Diagnostic Trouble Codes (DTCs).
    • Using a diagnostic scan tool, perform the RCM  self-test to retrieve Diagnostic Trouble Codes (DTCs).

    Was DTC B11D8:14 retrieved on-demand during self-test? 

    1. Yes  : GO to  A7
    2. No  : GO to  A9
  5. A5 CHECK THE EVENT NOTIFICATION SIGNAL CIRCUIT DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE 
    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.
    • Disconnect BCM C2280C  .
    • Using a diagnostic scan tool, perform the RCM  self-test to retrieve Diagnostic Trouble Codes (DTCs).

    Was DTC B11D8:12 retrieved on-demand during self-test? 

    1. Yes  : CONNECT BCM C2280C  . GO to  A6
    2. No  : CONNECT BCM C2280C  . 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 BCM  .

      REFER to: BODY CONTROL MODULE (BCM) .

      GO to  A9

  6. A6 CHECK THE EVENT NOTIFICATION SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE 

    Is any voltage present? 

    1. Yes  : CONNECT BCM C2280C  . REPAIR the circuit.

      Refer to OEM CONNECTOR REPAIR PROCEDURES EXCEPT ELECTRIC--> for schematic and connector information.

      GO to  A9

    2. No  : CONNECT BCM C2280C  . GO to  A7
  7. A7 CONFIRM THE RCM (RESTRAINTS CONTROL MODULE) FAULT 
    NOTE: Make sure all SRS  electrical connectors and the BCM  electrical connector are connected before carrying out the self-test. If not, Diagnostic Trouble Codes (DTCs) will be recorded.

    Was the original DTC retrieved on-demand 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  A9

    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. SRS  components should only be installed when directed to do so in the pinpoint test. GO to  A8
  8. A8 CHECK FOR AN INTERMITTENT FAULT 

    Was DTC B11D8:12 or B11D8:14 retrieved on-demand during self-test? 

    1. Yes  : The fault condition is now present. This fault cannot be cleared until it is corrected and the DTC  is no longer retrieved on-demand during the self-test. For DTC  B11D8:14, GO to  A2 For DTC  B11D8:12, GO to  A5
    2. No  : CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. ACTIVATE other systems in the same wire harness. Do not install any new SRS  components at this time. Only install SRS  components when directed to do so in the pinpoint test. REPAIR any intermittent concerns found. GO to  A9
  9. A9 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (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 connectors (if previously disconnected).
    • If previously directed to depower the SRS  , repower the SRS  . Do not prove out the SRS  at this time.

      REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .

    • Ignition ON.
    • NOTE: When selecting Restraints from the Self Test menu, Diagnostic Trouble Codes (DTCs) are retrieved from the RCM  and OCSM  .

      Using a diagnostic scan tool, perform the Restraints  self-test to retrieve Diagnostic Trouble Codes (DTCs).

    Are any RCM and/or OCSM Diagnostic Trouble Codes (DTCs) retrieved? 

    1. Yes  : Do not clear any Diagnostic Trouble Codes (DTCs) until all Diagnostic Trouble Codes (DTCs) have been resolved. Refer to DTC CHART: RCM or Refer to DTC CHART: OCSM for pinpoint test direction.
    2. No  : CLEAR all Diagnostic Trouble Codes (DTCs) in all modules. PROVE OUT the SRS  . The repair is complete. RETURN the vehicle to the customer.
