WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
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.
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: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
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: 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 parts catalog 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.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. Q1 RETRIEVE RCM DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Were 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 during self-test. GO to Q2.
    • No  : This is an intermittent fault when present as a CMDTC only. GO to  Q6.
  2. Q2 CHECK FOR INCORRECTLY INSTALLED ACCESSORIES 
    • Ignition OFF.
    • Verify that any installed accessories are not installed using any SRS component wiring regardless of whether that SRS component is installed on the vehicle.
    • Are any installed accessories using any SRS component wiring? 
    • Yes  : REMOVE the accessory or DISCONNECT all accessory wiring connections to the vehicle. REPEAT the self-test. If no RCM DTCs are present, ADVISE the customer that the aftermarket accessory must be removed or correctly installed. GO to  Q7. If incorrect component DTCs are still present, GO to Q3. If other RCM DTCs are retrieved, GO to the DTC CHARTS  for pinpoint test direction.
    • No  : GO to Q3.
  3. Q3 CHECK THE ABS MODULE 
    • Ignition OFF.
    • Check the part number on the ABS module against the part number listed in the parts catalog.
    • Does the part number on the ABS module match? 
  4. Q4 CHECK THE RCM 
    • Ignition ON.
    • Carry out PMI for the RCM using as-built data. Refer to MODULE CONFIGURATION .
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Were any incorrect component installed DTCs retrieved on-demand during self-test? 
    • Yes  : GO to Q5.
    • No  : Fault corrected. GO to  Q7.
  5. Q5 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.
    • Prior to reconnecting any previously disconnected SRS component:
      • inspect connector(s) (including any in-line connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
      • inspect wire harness for any damage, 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 "OEM Connector Repair Procedures" Article for schematic and connector information.
    • 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 .
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Were any incorrect component installed DTCs retrieved on-demand during self-test? 
    • Yes  : INSTALL a new RCM. REFER to RESTRAINTS CONTROL MODULE (RCM) . GO to  Q7.
    • 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 Q6.

  6. Q6 CHECK FOR AN INTERMITTENT FAULT 
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
    • Were any DTCs retrieved on-demand during self-test? 
    • Yes  : INSTALL a new RCM. REFER to RESTRAINTS CONTROL MODULE (RCM) . GO to Q7.
    • 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  . GO to Q7.
  7. Q7 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 - RCM.
    • Are any RCM DTCs retrieved on-demand during self-test? 
    • 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 CMDTCs. PROVE OUT the SRS. The repair is complete. RETURN the vehicle to the customer.
