Panic Alarm Function

When ignition knob switch is OFF (when ignition switch is not pressed) and key switch is OFF (when mechanical key is not inserted in key cylinder), Intelligent Key unit receives PANIC ALARM signal from remote control of Intelligent Key.

Intelligent Key unit sends alarm request signal to BCM via CAN communication line.

BCM turns on and off headlamp intermittently and sends theft warning horn signal to IPDM E/R. Then, IPDM E/R turns on and off horn intermittently.

The headlamp flashes and the horn sounds intermittently.

The alarm automatically turns off:

  • After 25 seconds
  • When Intelligent Key unit receives any signal from remote control of Intelligent Key
  • When a door request switch is pressed (Intelligent Key is outside vehicle)

Panic alarm function mode can be changed by "PANIC ALARM DELAY" mode in "WORK SUPPORT". Refer to "WORK SUPPORTΒ ".
