    Go to  AF9.
  5. AF5: VERIFY THE SUSPECT IMPACT SENSOR PART NUMBER 
    • Ignition OFF.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering in Supplemental Restraint System article.
    • Gain access to the suspect impact sensor for which incorrect component installed DTCs were retrieved. Refer to the EDGE SRS COMPONENT LIST  for the appropriate procedure title.

    Go to  AF9.
  6. AF6: CONFIRM THE RCM FAULT 
    NOTE: Make sure all SRS components and the RCM electrical connectors are connected before carrying out the self-test. If not, DTCs are recorded.
    • Ignition OFF.
    • Depower the SRS. Refer to Supplemental Restraint System (SRS) Depowering in Supplemental Restraint System article.
    • Prior to reconnecting any previously disconnected SRS component:
      • inspect connector(s) (including any inline connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
      • inspect wire harness for any damaged, pinched, cut or pierced wires.
      • inspect the RCM electrical connectors and the Connector Position Assurance (CPA) levers/locks for correct operation.
      • repair any concerns found. Refer to Connector Repair Procedures article, for schematic and connector information.
    • Connect all previously disconnected restraint system component(s).
    • RCM_A connector connected. (C310A) (if previously disconnected). Make sure it seats and latches correctly.
    • RCM_B connector connected. (C310B) (if previously disconnected). Make sure it seats and latches correctly.
    • Repower the SRS. Do not prove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Repowering in Supplemental Restraint System article.
    • Ignition ON, engine OFF.
    • Carry out the RCM self-test.
    • Is the original DTC retrieved on-demand during self-test? 
    Yes No
    Go to  AF7. In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time.

    Yes No
    This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test.
    Go to  AF6.    		 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  AF9.
  9. AF9: CHECK FOR ADDITIONAL SRS DIAGNOSTIC TROUBLE CODES (DTCS) 
    • Ignition OFF.
    • 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) Repowering in Supplemental Restraint System article.
