id0903f5800200

1

The security light display is not normal.

DESCRIPTION

• The security light remains illuminated 2 min or more after the ignition switch is turned to the ON position
• The security light does not illuminate when the ignition switch is turned to the ON position.
• 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

• Advanced keyless control module malfunction (with advanced keyless control system)
• Keyless control module malfunction (without advanced keyless control system)
• Instrument cluster malfunction
• Open or short circuit in the wiring harness between the instrument cluster and keyless control module (without advanced keyless control system)/Advanced keyless control module (with advanced keyless control system)
Note
• If the security light remains illuminated for approx. 1 min after the ignition switch is turned to the ON position and then displays a DTC, perform immobilizer system malfunction diagnosis according to that DTC. (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.
