PINPOINT TEST A : U0151:00 

1. WARNING: Do not handle, move or change the original horizontal mounting position of the Restraints Control Module (RCM) while the Restraints Control Module (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.
2. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
3. 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.
4. 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 parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
5. A1 CHECK THE COMMUNICATION NETWORK
   
   
   • WARNING: Before beginning any service procedure, refer to Safety Warnings. Failure to follow this instruction may result in serious personal injury.

     REFER to: Pyrotechnic Device Health and Safety Precautions .

   • Ignition ON.
   • Using a diagnostic scan tool, carry out a network test.

   Does the RCM pass the network test? 

   Yes

   GO to  A2

   No	To diagnose no communication with the RCM, REFER to: Communications Network .

6. A2 CHECK THE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CM DTCS)
   
   
   • Using a diagnostic scan tool, perform OCSM self-test.
   • Using a diagnostic scan tool, clear OCSM Diagnostic Trouble Codes (DTCs).
   • Wait 10 seconds.
   • Using a diagnostic scan tool, perform OCSM self-test.

   Is DTC U0151:00 retrieved again? 

   Yes

   GO to  A3

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

7. A3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE RCM (RESTRAINTS CONTROL MODULE) SELF-TEST
   
   
   • Using a diagnostic scan tool, perform RCM self-test.

   Is DTC U3003:16 or U3003:17 recorded? 

   Yes	REFER to: Pinpoint Test - DTC: AU .

   No

   GO to  A4

8. A4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) SELF-TEST
