•  The security light remains illuminated while the ignition switch is at the LOCK position.
•  The security light does not flash or the flashing interval is abnormal while the ignition switch is at the LOCK position.
POSSIBLE CAUSE
•  Keyless control module malfunction (with advanced keyless and start system)
•  Instrument cluster malfunction
Note
•  If the security light continues to remain illuminated or flashing even after 1 min has elapsed since the ignition switch was turned to the ON position and a DTC is displayed, perform the immobilizer system malfunction diagnosis according to that DTC. (See DTC TABLE [IMMOBILIZER SYSTEM (ADVANCED KEYLESS AND START SYSTEM)].)(See DTC TABLE [IMMOBILIZER SYSTEM (KEYLESS ENTRY SYSTEM)].)
•  While performing immobilizer system security access using the M-MDS, the security light does not illuminate even if the ignition switch is turned to the ON position. Verify the illumination condition of the security light by disconnecting the DLC-2 to release security access.
•  The flashing security light conditions while the ignition switch is in the LOCK position are as follows:

Note
•  Normal operation of the security light is as follows. The light starts flashing every 2 s when the ignition switch is turned from ON to ACC position and the immobilizer system is armed. The light stops flashing when the ignition switch is turned to the ON position with the correct ignition key. At this time, the immobilizer system is disarmed and the security light illuminates for about 3 s and then goes out.
