DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY WHETHER PROGRAMMING OF IMMOBILIZER SYSTEM-RELATED PARTS HAS BEEN PERFORMED AFTER REPLACE PCM After replace the PCM, has the programming of immobilizer system-related parts been performed?	Yes	Go to the next step.
1		No	Perform the programming of immobilizer system-related parts after replace the PCM only, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ).
2	VERIFY PCM MALFUNCTION Clear the DTC from the keyless control module and PCM using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). (See AFTER REPAIR PROCEDURE [LF, L5] ). (See AFTER REPAIR PROCEDURE [L3 WITH TC] ). Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [LF, L5] ). (See PCM REMOVAL/INSTALLATION [L3 WITH TC] ).
2		No	Go to Step 4.
3	VERIFY TROUBLESHOOTING COMPLETED Clear the DTC from the keyless control module and PCM using the M-MDS. (See CLEARING DTC [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). (See AFTER REPAIR PROCEDURE [LF, L5] ). (See AFTER REPAIR PROCEDURE [L3 WITH TC] ). Perform the immobilizer system DTC inspection using the M-MDS. (See DTC INSPECTION [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ). Is the same DTC present?	Yes	Replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION ).
3		No	Go to the next step.
4	VERIFY THAT NO OTHER DTCs ARE PRESENT Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ).
4		No	DTC troubleshooting completed.
