id0903f5800200

1
The security light display is not normal
DESCRIPTION
•  The security light remains illuminated 2 min or more after the ignition is switched to ON
•  The security light does not illuminate when the ignition is switched to ON
•  The security light remains illuminated while the ignition is switched off
•  The security light does not flash or the flashing interval is abnormal while the ignition is switched off
POSSIBLE CAUSE
•  Keyless control module malfunction (with advanced keyless entry and push button start system)
•  Instrument cluster malfunction
Note
•  If the security light remains illuminated for approx. 1 min after the ignition switch is turned to ON and a DTC is displayed, perform the immobilizer system malfunction diagnosis according to that DTC. (See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
•  While performing the immobilizer system security access using the M-MDS, the security light does not illuminate even if the ignition is switched to ON. Verify the illumination condition of the security light by disconnecting the DLC-2 to release security access.

Note
•  Normal operation of the security light is as follows. The light starts flashing every 2 s when the ignition is switched from ON to ACC and the immobilizer system is armed. The light stops flashing when the ignition is switched to ON 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.
