BXXXX:4A (Any BXXXX DTC with failure type 4A) Incorrect Component Installed

Normal Operation and Fault Symptoms

The RCM monitors all SRS device connections. If the RCM detects a connected device that is not stored in memory or not configured for the component, the RCM sets a DTC and sends a message to the IPC to illuminate the airbag indicator.

  • RCM is not configured or is incorrectly configured

PINPOINT TEST A: BXXXX:4A (ANY BXXXX DTC WITH FAILURE TYPE 4A) INCORRECT COMPONENT INSTALLED
NOTE: Most concerns are related to connector and/or wiring issues. Perform a thorough inspection and check before proceeding to the Pinpoint Test.
NOTE: Only disconnect or reconnect SRS components when instructed to do so in the Pinpoint Test step. Failure to follow this instruction may result in an incorrect SRS diagnosis.
NOTE: Always verify the correct SRS component is installed. Parts released for other vehicles may be incompatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to confirm the correct component is installed. If an incorrect SRS component is installed, diagnostic trouble codes (DTCs) may be set.
NOTE: Before returning the vehicle to the customer, the SRS must be fully functional and operating correctly.
A1 REMOVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
  • WARNING: Before starting any service procedure in this section, refer to the Safety Warnings in Section 100-00 General Information. Failure to follow this instruction may result in serious personal injury.
    REFER TO: Pyrotechnic Device Handling Precautions (100-00 General Information, Description and Operation).
  • The ignition is on.
  • Using the diagnostic scanner, perform the RCM self-test.

Were any incorrectly installed component DTCs retrieved on demand during the self-test?
Yes This fault cannot be cleared until it is repaired and the DTC is no longer retrieved during the self-test.
If DTC B00A0:4A was retrieved,
REFER TO: Pinpoint Test - DTC: K (501-20B Supplemental Restraint System, Diagnosis and Testing). For all other incorrect component DTCs that are set, GO to A2.
No This is an intermittent fault when present as a continuous memory diagnostic trouble code (CMDTC) only. GO to A7
A2 CHECK VEHICLE HISTORY
  • Ignition OFF.
  • Check the vehicle repair history.

Was a new RCM or OCSM installed during this or a previous repair?
Yes GO to A3
No GO to A4
A3 CHECK RCM (RESTRAINTS CONTROL MODULE) AND OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) PARAMETER IDENTIFICATION (PIDS)
  • The ignition is on.
  • Using the diagnostic scan tool, view the RCM parameter identification (PID) data.
  • View and record the value displayed by the following parameter identifications (PIDs):
    • V_ID_14229_RCM
    • OCS_MY
  • Using the diagnostic scan tool, view the OCSM parameter identifications (PIDs).
  • View and record the value displayed by the following parameter identifications (PIDs):
    • V_ID_14229_OCS
    • MY_14229
  • Check the vehicle application.

Do the PID values match the vehicle application?
Yes GO to A4
No INSTALL the correct RCM or OCSM.
REFER TO: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation).
REFER TO: Occupant Classification System (OCS) Sensor (501-20B Supplemental Restraint System, Removal and Installation).
GO to A8
A4 CHECK ABS (ANTI-LOCK BRAKE SYSTEM) MODULE PART NUMBER
  • The ignition is on.
  • Using the scan tool log function, retrieve and record the ABS module part number.
  • Compare the recorded part number with the number listed in the Ford Parts Catalog and confirm the correct ABS module is installed on the vehicle.

Is the correct ABS module installed?
Yes GO to A5
No INSTALL the correct ABS module.
REFER TO: Hydraulic Control Unit (HCU) (206-09 Anti-Lock Brake System (ABS) and Stability Control System, Removal and Installation).
GO to A8
A5 CHECK RCM (RESTRAINTS CONTROL MODULE) CONFIGURATION
  • Perform the PMI for the RCM. Use the scan tool actuator data when performing the PMI. Refer to the scan tool instructions for performing the PMI.
  • Using the diagnostic scanner, perform the RCM self-test.

Were any incorrectly installed component DTCs retrieved on demand during the self-test?
Yes GO to A6
No The fault is repaired. GO to A8
A6 CONFIRM RCM (RESTRAINTS CONTROL MODULE) FAULT
  • Ignition OFF.
  • De-power the SRS.
    REFER to: Supplemental Restraint System (SRS) Disabling and Re-enabling (501-20B Supplemental Restraint System, General Procedures).
  • Disconnect: RCM C310A and C310B.
  • Before reconnecting any previously disconnected SRS component:
    • inspect the connector(s) (including any integral connectors) for pushed-out, loose or spread terminals, and loose or chafed wire connections at the terminals.
    • Inspect the wiring harness for damage, pinching, cuts or punctures in the wires.
    • check the RCM C310A and C310B connector position assurance (CPA) lever/latch for proper operation.
    • repair any problems found.
      Refer to Wiring Diagrams Cell 5 for schematic and connector information.
  • Connect: RCM C310A and C310B.
  • Reset the SRS. Do not check the SRS at this time.
    REFER TO: Supplemental Restraint System (SRS) Disarming and Rearming (501-20B Supplemental Restraint System, General Procedures).
  • The ignition is on.
  • Using the diagnostic scanner, perform the RCM self-test.

Were any incorrectly installed component DTCs retrieved on demand during the self-test?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, STOP this test and FOLLOW the TSB instructions. If no TSBs apply to this concern, INSTALL a new RCM.
REFER TO: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation).
GO to A8
No During the diagnostic procedure the condition became intermittent. Do not install new SRS components at this time. Install SRS components only if directed by the pinpoint test. GO to A7
A7 CHECK FOR INTERMITTENT FAULT
  • Using a diagnostic scan tool, perform the RCM self-test to retrieve diagnostic trouble codes (DTCs).

Were any incorrectly installed component DTCs retrieved on demand during the self-test?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, STOP this test and FOLLOW the TSB instructions. If no TSBs apply to this concern, INSTALL a new RCM.
REFER TO: Restraints Control Module (RCM) (501-20B Supplemental Restraint System, Removal and Installation).
GO to A8
No CHECK for causes of intermittent fault. ATTEMPT to recreate the intermittent fault by flexing the wiring harness and performing repeated ignition cycles. ACTUATE other systems on the same wiring harness. At this time do not install any new SRS components. Install SRS components only when directed by the pinpoint test. GO to A8
A8 CHECK SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DIAGNOSTIC TROUBLE CODES (DTCS)
  • Ignition OFF.
  • Reconnect all SRS components (if previously disconnected).
  • If previously instructed to disable the SRS, re-enable the SRS. Do not check the SRS at this time.
    Refer to: Supplemental Restraint System (SRS) Disabling and Arming (501-20B Supplemental Restraint System, General Procedures).
  • The ignition is on.
  • NOTE: When Restraints is selected in the Self Test menu, DTCs are retrieved from the RCM and OCSM. Using the diagnostic scanner, perform the Restraints Self Test.

Are any RCM and/or OCSM Diagnostic Trouble Codes (DTCs) retrieved on demand during the self-test?
Yes Do not clear any Diagnostic Trouble Codes (DTCs) until all DTCs have been resolved. DIAGNOSE and REPAIR the RCM and/or OCSM DTCs.
Refer to: Supplemental Restraint System (SRS) (501-20B).
No CLEAR all RCM and OCSM continuous memory diagnostic trouble codes (CMDTCs). VERIFY SRS. Repair is complete. RETURN the vehicle to the customer.
