WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
  1. Refer to Wiring Diagrams SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.

    Normal Operation and Fault Conditions 

    REFER to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - System Operation and Component Description .

    The RCM is in constant communication with various control modules on the HS-CAN. One of those modules is the OCSM. The RCM continuously monitors the HS-CAN for fault messages reported by the OCSM. The RCM also checks for the correct identification of the OCSM. If the RCM receives fault message(s) from the OCSM, it stores DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and sends a message to the IPC to illuminate the airbag warning indicator.

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    RCM B00A0:09 Occupant Classification System: Component Failures A fault is indicated when the RCM receives a message from the OCSM that a fault exists within the OCS.
    RCM B00A0:63 Occupant Classification System: Circuit/Component Protection Time-Out A fault is indicated when the RCM receives 8 or more invalid states from the OCSM.
    RCM B00A0:64 Occupant Classification System: Signal Plausibility Failure A fault is indicated when the RCM receives messages containing upper or lower data limits other than limits stored in memory.
    RCM B00A0:68 Occupant Classification System: Event Information A fault is indicated when the RCM receives a message from the OCSM that indicates an OCS fault is present.

    Possible Sources 

    • Wiring, terminals or connectors
    • OCSM
    • RCM

  2. 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.
  3. NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
  4. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  5. 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.
  6. NOTE: Install new components only when directed to do so in the pinpoint test.
  7. 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, Diagnostic Trouble Codes (DTCs) may set.
  8. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

  9. R1 RETRIEVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • WARNING: Before beginning any service procedure In this article, refer to Safety warnings in General Information. Failure to follow this instruction may result in serious personal injury.

      REFER to: Pyrotechnic Device Health and Safety Precautions .

    • Ignition ON.

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

    Was DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 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 B00A0:09, B00A0:63 or B00A0:68, RETRIEVE Diagnostic Trouble Codes (DTCs) from the OCSM and DIAGNOSE those Diagnostic Trouble Codes (DTCs). REFER to the OCSMDTC chart In this article. For DTC B00A0:4A or B00A0:64, GO to  R2
    No  CHECK for causes of the intermittent fault. Refer to Wiring Diagrams OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information. 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  R5

  10. R2 VERIFY THE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) PART NUMBER

    • Using the Log Viewer function of the diagnostic scan tool, retrieve and record the OCSM part number.

    • Check the part number recorded against the number listed in the parts catalog and verify the correct OCSM is present in the vehicle.

    Is the correct OCSM installed? 

    Yes  GO to  R3
    No  INSTALL the correct OCSM. REFER to: Occupant Classification System (OCS) Sensor - Vehicles With: Multi-Contour Seats . or REFER to: Occupant Classification System (OCS) Sensor - Vehicles Without: Multi-Contour Seats . GO to  R5

  11. R3 VERIFY THE RCM (RESTRAINTS CONTROL MODULE) PART NUMBER

    • Using the Log Viewer function of the diagnostic scan tool, retrieve and record the RCM part number.

    • Check the part number recorded against the number listed in the parts catalog and verify the correct RCM is present in the vehicle.

    Is the correct RCM installed? 

    Yes  GO to  R4
    No  INSTALL the correct RCM. REFER to: Restraints Control Module (RCM) . GO to  R5

  12. R4 VERIFY THE RCM (RESTRAINTS CONTROL MODULE) CONFIGURATION

    • Carry out PMI for the RCM. Manually enter As-Built data. Refer to the diagnostic scan tool instructions when carrying out PMI.

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

    Was DTC B00A0:4A retrieved on-demand during self-test? 

    Yes  CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new RCM. REFER to: Restraints Control Module (RCM) . GO to  R5
    No  The fault is corrected. GO to  R5

  13. R5 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Ignition OFF.

    • Ignition ON.

    • NOTE: When selecting Restraints from the Self Test menu, DTCs are retrieved from the RCM and OCSM.

      Using a diagnostic scan tool, perform

      Restraints  self-test.

    Are any RCM or OCSM Diagnostic Trouble Codes (DTCs) retrieved on-demand during self-test? 

    Yes  Do not clear any Diagnostic Trouble Codes (DTCs) until all  Diagnostic Trouble Codes (DTCs) have been resolved. DIAGNOSE and REPAIR the SRS Diagnostic Trouble Codes (DTCs). REFER to the DTC Chart In this article.
    No  The repair is complete. RETURN the vehicle to the customer.
