Keyless/Power Door Locks/Security System Description - Overview (2015)
Keyless Entry System
The keyless entry system is integrated with the multiplex integrated control system. The multiplex integrated control unit (MICU) receives LOCK, UNLOCK, and PANIC signals from the keyless access control unit.
The keyless entry system allows you to lock and unlock the vehicle with the transmitter. When you press the LOCK button, all doors lock. When you press the UNLOCK button once, only the driver's door unlocks. The other doors will unlock when you press the button a second time. (Depending on the settings in the vehicle, all the doors may unlock when you press the button the first time.) The doors will not lock with the transmitter if a door is not fully closed, or if the vehicle is in the ON mode.
When the switch for the interior light is in the middle (DOOR) position, it comes on when the UNLOCK button is pressed. If a door is not opened, the light goes off and the doors will relock in about 30 seconds. If the doors are locked with the transmitter within 30 seconds, the light goes off immediately.
NOTE: The keyless entry system can be customized to suit the customer's needs. For more information about keyless/security system options, refer to the Owner's Manual.
Door Lock System
The system has a pair of circuits between the door lock actuators and the MICU (including the trunk lid actuator) to improve safety of the system. One is for the driver's side door lock actuators, and another is for the passenger's side door lock actuators. Each circuit has two fuses, and even if one of the fuses is blown, at least the driver's side or the passenger's side actuators continue to work normally. When one fuse is blown, another fuse in the same circuit must be checked.
Security Alarm System
The security alarm system is automatically armed after the doors, the hood, and the trunk lid are closed and locked. For the system to be armed the vehicle must be OFF mode and the MICU must receive inputs that the doors, the hood, and the trunk lid are closed and locked. The alarm can be disarmed at any time by unlocking the driver door with the ignition key or pressing the UNLOCK button on the keyless transmitter or the remote.
When everything is closed and locked, the only inputs that are grounded, and have 0 V, are the driver's door lock knob switch (LOCK position) input and the audio unit or audio-navigation unit (if equipped) security input. In other words, all of the other switches are open, and have about 10 to 12 V, including the key cylinder switches. The security indicator in the gauge control module begins to flash immediately after the vehicle is completely closed and locked, and 15 seconds later, the security system will be armed. If the security indicator does not flash after the doors are locked, the system is not armed.
If one of the switches is misadjusted or shorted internally, or there is a short in one of the keyless/power door locks/security circuits, the security system will not be armed. A switch that is slightly misadjusted can cause the alarm to sound for no apparent reason. In this case, a significant change in outside air temperature, the vibration of a passing truck, or someone bumping into the vehicle could cause the alarm to sound.
Once the system is armed, it will sound an alarm when any of these occur:
- A door or the trunk lid is forced open.
- A door is unlocked without using the ignition key, the keyless transmitter or the remote.
- The hood is opened.
- The audio unit or audio-navigation unit (if equipped) is disconnected.
- Shift position was moved to other than P position.
- Turning the vehicle to the ON mode from the OFF (LOCK) mode.
- The transmitter PANIC button is pressed.
When the system sounds the alarm, the horn sounds and the turn signal lights flash for 2 minutes. The alarm can be stopped at any time by unlocking the door by pressing the UNLOCK button on the keyless transmitter or the remote.
NOTE: The security system can be customized to suit the customer's needs. For more information about keyless/security system operation, refer to the Owner's Manual.
Panic Mode
The panic mode sounds the alarm in order to attract attention. When the PANIC button on the remote or the keyless transmitter is pressed and held for 2 seconds, the horns sound and the exterior lights flash for about 30 seconds.
The panic mode can be canceled at any time by pressing any button on the remote or by turning the vehicle to the ON mode. The panic mode will not function if the vehicle is the ON mode.
