CKP Pattern Clear/CKP Pattern Learn Procedure

NOTE:
Clearing the DTCs with the HDS does not require you to do this procedure.
The PCM memorizes the learning status in its memory after passed an hour from turning the vehicle to the OFF (LOCK) mode. If you need to disconnect the 12 volt battery terminals before memorizing the learning status in the PCM, jump the SCS line with the HDS, and wait 60 seconds, then disconnect the 12 volt battery terminals.
