WARNING: This page is about a different car, the 2012 Ford Pickup. 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 air bag, Safety Canopy® or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, 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: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Only disconnect or reconnect Supplemental Restraint System (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.
  1. W1 RETRIEVE RCM DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM.
      NOTE: Signal cross coupled DTCs are retrieved only in pairs.
    • Were any signal cross coupled 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 the on-demand self test. GO to  W2.
      • No  : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to  W4.
  2. W2 CHECK THE AFFECTED DEPLOYABLE CIRCUITS FOR A SIGNAL CROSS COUPLED FAULT 
    • Ignition OFF.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering  .
    • Disconnect: RCM C310A and C310B.
    • Disconnect ALL of the affected SRS devices.
      NOTE: Most signal cross coupled faults are due to connector and/or wiring harness damage. Carry out a thorough inspection of connector(s) and/or wiring harness for damage.

      Using the following table, measure resistance between the circuits of the affected SRS devices.

  3. W3 CONFIRM THE RCM FAULT 
    NOTE: Make sure all restraint system components, sensor electrical connectors 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 C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation. REFER to Restraints Control Module (RCM)  .
      • repair any concerns found. Refer to OEM CONNECTOR REPAIR PROCEDURES - F150 Connector Repair Procedures for schematic and connector information.
    • Connect: All Previously Disconnected Restraint System
    • Component(s).
    • Connect: RCM C310A and C310B.
    • 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.
    • Were any signal cross coupled DTCs retrieved on-demand during self-test? 
      • Yes  : INSTALL a new RCM. REFER to Restraints Control Module (RCM)  . GO to  W5.
      • No  : In the process of diagnosing the fault, the fault condition has become intermittent. 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  W4.
  4. W4 CHECK FOR AN INTERMITTENT FAULT 
    NOTE: Most cross link faults are due to connector and/or wiring harness damage. Carry out a thorough inspection of connector(s) and/or wiring harness for damage.
    • Ignition OFF.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering and Repowering  .
    • Disconnect ALL of the affected SRS devices.
    • Inspect the wiring harness(es) for any type of damage. Repair as necessary. Refer to OEM WIRING DIAGRAMS Supplemental Restraint System for schematic and connector information.
    • 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.
    • Were any signal cross coupled DTCs retrieved on-demand during self-test? 
      • 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. GO to  W2.
      • No  : The fault is not present and cannot be recreated at this time.

        CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. 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  W5.

  5. W5 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 are retrieved from the RCM and OCSM.
    • Are any 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 DTCs. PROVE OUT the SRS. The repair is complete. RETURN the vehicle to the customer.
