DISARMED Phase
The vehicle security system is not set in the DISARM ED phase. The vehicle security system stays in this
phase while any door is open, because it is assumed that the owner is inside or nearby the vehicle. Security
indicator lamp blinks every 2.4 seconds.
When the vehicle security system is reset, each phase switches to the DISARMED phase directly.
PRE-ARMED Phase
The PRE-ARMED phase is the transient state bet ween the DISARMED phase and the ARMED phase. This
phase is maintained for 30 seconds, so that the owner c an reset the setting due to a mis-operation. This phase
switches to the ARMED phase when vehicle conditions are not changed for 30 seconds. Security indicator
lamp illuminates while being in this phase.
To reset the PRE-ARMED phase, refer to the switching condition of No. 10 in the table above.
ARMED Phase
The vehicle security system is set, and BCM monitors all necessary inputs. If any door or hood is opened with-
out using Intelligent Key, vehicle security system switc hes to the ALARM phase. Security indicator lamp blinks
every 2.4 seconds.
To reset the ARMED phase, refer to the switching condition of No. 11 in the table above.
ALARM Phase
BCM transmits “Theft Warning Horn Request” signal and “High Beam Request” signal intermittently to IPDM
E/R via CAN communication. In this phase, horns and headlamps are activated intermittently for approxi-
mately 50 seconds to warn that the vehicle is accessed by unauthorized means. ON/OFF timing of horns and
headlamps are synchronized. After 50 seconds, the vehi cle security system returns to the ARMED phase. At
