DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	CONFIRM IMMOBILIZER SYSTEM DTC 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 following DTC present? Keyless control module: B10D7:05 PCM: P1260:00	Yes	Perform the security light: 13, DTC: B10D7:05/P1260:00 inspection. (See SECURITY LIGHT: 13, DTC: B10D7:05/P1260:00 [IMMOBILIZER SYSTEM (ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM)] ).
1		No	Go to the next step.
2	VERIFY WHETHER THERE IS A VALID KEY Are there any valid keys which can start the engine other than the cause of the displayed DTC?	Yes	Go to the next step.
2		No	Program an additional key referring to the immobilizer system-related parts programming, then go to the next step. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ).
3	VERIFY WHETHER MALFUNCTION IS CAUSED BY KEY OR COIL ANTENNA Switch the ignition to ON using the valid key other than the cause of the displayed DTC (engine off). 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 following DTC present? Keyless control module: B10D7:94 PCM: P1260:00	Yes	Replace the coil antenna, then go to the next step. (See COIL ANTENNA REMOVAL/INSTALLATION ).
3		No	Dispose of the malfunctioning key and program a new key if necessary, then go to Step 6. (See IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM] ). NOTE: To start the engine, two or more programmed keys are necessary.
4	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 following DTC present? Keyless control module: B10D7:94 PCM: P1260:00	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [LF, L5] ). (See PCM REMOVAL/INSTALLATION [L3 WITH TC] ).
4		No	Go to Step 6.
5	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 following DTC present? Keyless control module: B10D7:94 PCM: P1260:00	Yes	Replace the keyless control module, then go to the next step. (See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION ).
5		No	Go to the next step.
6	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)] ).
6		No	DTC troubleshooting completed.
