1. AZ1: CHECK THE COMMUNICATION NETWORK 
   • Ignition ON, engine OFF.
   • Press the Read Vehicle Information button to view the results of the modules communicating on the network.
   • Retrieve the continuous memory DTCs.
   • Does the SECM pass the Network Test? 

   Yes	No
   Go to  AZ2.	DIAGNOSE the scan tool does not communicate with the SECM. REFER to the Module Communications Network article.

2. AZ2: RECHECK THE SASM FOR THE LOST COMMUNCATION DTC 
   • Clear the SASM DTCs.
   • Ignition OFF.
   • Ignition ON, engine OFF.

     Carry out the SASM self-test.

   • Is DTC U0130:xx still present? 

   Yes	No
   Go to  AZ3.	The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

3. AZ3: REVIEW THE SASM SELF-TEST FOR VOLTAGE-REALTED DTCS 
   • Review the results from the SASM self-test.
   • Is DTC U3003:1C or U3003:17 present? 

   Yes	No
   For DTC U3003:1C, Go to PINPOINT TEST BD . For DTC U3003:17, Go to PINPOINT TEST BE . For all others, No fault found.	Go to  AZ4.

4. AZ4: CHECK FOR SECM DTCS 

   Carry out the SECM self-test.

   • Are any DTCs present? 

   Yes	No
   DIAGNOSE the SECM DTC. REFER to the appropriate Power Steering article.	Go to  AZ5.

5. AZ5: CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN 
   NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.
   • Check the vehicle service history for recent service actions related to the SECM or SASM. If recent service history is found:
     • Verify the correct replacement module was installed. HVBOM may be used to verify correct part fitment.
     • Verify the configuration of replacement module was correct. Re-configure the module using as-built data if prior configuration is suspect.
     • Verify the module was not obtained from a like vehicle and installed into customer vehicle. Return the swapped module to source vehicle and obtain new replacement module.
   • Operate the system and determine if the observable symptom is still present.
   • Is the observable symptom still present? 

   Yes	No
   Go to  AZ6.	The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

6. AZ6: CHECK FOR COMMUNICATION DTCS IN OTHER MODULES 
   • Ignition ON, engine OFF.
   • Retrieve the continuous memory DTCs.
   • Is DTC U0130:xx set in 1 or more modules in addition to the SASM? 

   Yes	No
   Go to  AZ8.	Go to  AZ7.

7. AZ7: VERIFY SECM OPERATION 
   • Ignition OFF.
   • SECM_A connector disconnected. (C2391A)
   • SECM_B connector disconnected. (C2391B)
   • SECM_C connector disconnected. (C2391C)
   • SASM connector disconnected. (C2414)
   • Using a good light source, inspect all disconnected electrical connectors for the following:
     • corrosion - install new connector or terminal and clean the module pins
     • damaged or bent pins - install new terminals or pins
     • pushed-out pins - install new pins as necessary
     • spread terminals - install new terminals as necessary
   • SASM connector connected. (C2414) Make sure the connector seats and latches correctly.
   • SECM_C connector connected. (C2391C) Make sure the connector seats and latches correctly.
   • SECM_B connector connected. (C2391B) Make sure the connector seats and latches correctly.
   • SECM_A connector connected. (C2391A) Make sure the connector seats and latches correctly.
   • Operate the system and verify the concern is still present.
   • Is the concern still present? 

   Yes	No
   INSTALL a new SECM. CHECK OASIS for any service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no services articles address this concern, INSTALL a new sateering wheel (the SECM is part of the steering wheel). REFER to the Steering Column article.	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.

8. AZ8: VERIFY SASM OPERATION 
   • Ignition OFF.
   • SASM connector disconnected. (C2414)
   • SECM_A connector disconnected. (C2391A)
   • SECM_B connector disconnected. (C2391B)
   • SECM_C connector disconnected. (C2391C)
   • Using a good light source, inspect all disconnected electrical connectors for the following:
     • corrosion - install new connector or terminal and clean the module pins
     • damaged or bent pins - install new terminals or pins
     • pushed-out pins - install new pins as necessary
     • spread terminals - install new terminals as necessary
   • SECM_C connector connected. (C2391C) Make sure the connector seats and latches correctly.
   • SECM_B connector connected. (C2391B) Make sure the connector seats and latches correctly.
   • SECM_A connector connected. (C2391A) Make sure the connector seats and latches correctly.
   • SASM connector connected. (C2414) Make sure the connector seats and latches correctly.
   • Operate the system and verify the concern is still present.
   • Is the concern still present? 

   Yes	No
   INSTALL a new SASM. CHECK OASIS for any service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no services articles address this concern, INSTALL a new SASM - clockspring assembly. REFER to the Supplemental Restraint System article.	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues. If this is a Ford paid repair, INCLUDE the RVC on the warranty claim form.
