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 | • Keyless unit malfunction • Instrument cluster malfunction • Open or short circuit in the wiring harness between the instrument cluster and keyless unit 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).) • While performing immobilizer system security access using the WDS, 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.
