The scan tool only displays the condition that inhibits the procedure. The scan tool monitors the following components:
    
    NOTE

    While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.
    
    
    
    
    Crankshaft position (CKP) sensors activity--If there is a CKP sensor condition, refer to the applicable DTC

    Camshaft position (CMP) signal activity--If there is a CMP signal condition, refer to the applicable DTC

    Engine Coolant Temperature (ECT)--If the engine coolant temperature is not warm enough, idle the engine until the engine coolant temperature reaches the correct temperature
75. Enable the CKP system variation learn procedure with the scan tool and perform the following:
    
    
    Accelerate to WOT

    Release throttle when fuel cut-off occurs
76. The scan tool displays Learn Status: Learned this ignition. If the scan tool indicates that DTC P0315 ran and passed, the CKP variation learn procedure is complete. If the scan tool indicates DTC P0315 failed or did not run, refer to DTC P0315. If any other DTCs set, refer to Diagnostic Trouble Code (DTC) List.
77. Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
78. The CKP system variation learn procedure is also required when the following service procedures have been performed, regardless of whether or not DTC P0315 is set:
    
    
    An engine replacement

    A PCM replacement

    A harmonic balancer replacement

    A crankshaft replacement

    A CKP sensor replacement

    Any engine repairs which disturb the crankshaft to CKP sensor relationship

These details will help.
