WARNING: This page is about a different car, the 2013 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Never probe the electrical connectors on airbag, Safety Canopy or side air curtain assemblies. Failure to follow this instruction may result in the accidental deployment of these assemblies, which increases the risk of serious personal injury or death.
WARNING: Never disassemble or tamper with seat belt deployable components, including pretensioners, load limiters and inflators. Never back probe deployable device electrical connectors. Tampering or back probing may cause an accidental deployment and result in personal injury or death.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: SRS components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
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, DTCs may set.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
  1. T1 RETRIEVE RCM DTCs 
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Was any incorrect component installed DTCs 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. GO to T2.
    • No  : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to  T6.
  2. T2 CHECK VEHICLE HISTORY 
    • Ignition OFF.
    • Check the vehicle repair history.
    • Has a new RCM or OCSM been installed during this or a prior repair? 
    • Yes  : GO to T3.
    • No  : GO to  T5.
  3. T3 CHECK RCM AND OCSM VEHICLE IDENTIFICATION PIDs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: DataLogger - RCM.
    • View and record the following PID values:
      • V_ID_14229_RCM
      • OCS_MY
    • Enter the following diagnostic mode on the scan tool: DataLogger - OCSM.
    • View and record the following PID values:
      • OCS_MY_OCS
      • OCS_VEH_ID
    • Verify the correct vehicle application.
    • Do the PID values match the vehicle application? 
  4. T4 CHECK ABS MODULE 
    • Ignition OFF.
    • Check the part number on the ABS module against the part number listed in the Ford Catalog Advantage™ or equivalent.
    • Does the part number on the ABS module match the part number listed in the Ford Catalog Advantage™ or equivalent? 
  5. T5 CHECK RCM 
    • Ignition ON.
    • Carry out Programmable Module Installation (PMI) for the RCM. Use as-built data when carrying out PMI. Refer to MODULE CONFIGURATION .
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Was any RCM incorrect component installed DTCs retrieved on-demand during self-test? 
    • Yes  : GO to  T6.
    • No  : Fault corrected. GO to  T8.
  6. T6 CONFIRM THE RCM FAULT 
    NOTE: Make sure all restraint system components and the RCM electrical connectors are connected before carrying out the self-test. If not, DTCs will be recorded.
    • Connect: All Previously Disconnected Component(s)/Connector(s).
    • Repower the SRS. Do not  prove out the SRS at this time. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Was any RCM incorrect component installed DTCs retrieved on-demand during self-test? 
    • Yes  : INSTALL a new RCM. REFER to RESTRAINTS CONTROL MODULE (RCM) . GO to  T8.
    • 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  . REPAIR any intermittent wiring, terminal or connector concerns found. Refer to appropriate "OEM Connector Repair Procedures" for information. GO to T7.

  7. T7 CHECK FOR INCORRECT COMPONENT INSTALLED 
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Was any incorrect component installed DTCs retrieved on-demand during self-test? 
    • Yes  : INSTALL new RCM. REFER to RESTRAINTS CONTROL MODULE (RCM) . GO to  T8.
    • 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. SRS components should only be installed when directed to do so in the pinpoint test  . REPAIR any intermittent wiring, terminal or connector concerns found. Refer to appropriate "OEM Connector Repair Procedures" for information. GO to  T8.
  8. T8 CHECK FOR ADDITIONAL SRS DTCs 
    • Ignition OFF.
      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.
    • Reconnect all SRS components (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.
    • Enter the following diagnostic mode on the scan tool: Self Test - Restraints.
      NOTE: When selecting Restraints from the Self Test menu, DTCs will be retrieved from the RCM and OCSM.
    • Are any on-demand RCM and/or OCSM DTCs retrieved? 
    • Yes  : Do not clear any DTCs until all DTCs have been resolved. GO to the DTC CHARTS  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.
