Keyless Access
Smart Entry Function
The body control module detects the input signal of the door outer handle touch sensor, the outer handle lock switch, or the trunk lid.
outer handle switch, and authenticates 2-way communication with the remote. The body control module then activates the door
lock/unlock actuator or trunk lid opener solenoid and provides an answer back signal.

Smart Entry Answer Back
Lock
When the body control module receives a lock signal by the smart entry function, it sends a signal to the turn signal lights and the keyless buzzer sounds.
Unlock
When the body control module receives an unlock signal by the smart entry function, it sends a signal two times to the turn signal lights and the keyless buzzer sounds.
Keyless Access System Operation Manual Customize
The keyless access system can be enabled and disabled by the operation shown in the table. The system is enabled and disabled
each time the unlock button is pressed on the remote in the customize mode.
Backup Communication Function (Immobilizer Function)
When key authentication between the remote and the body control module is not possible because of a system abnormality or a drop
of the battery voltage of the remote, the immobilizer function can be canceled by pressing the power switch once and bringing the
remote close to the power switch while the light of the power switch is flashing. This allows the immobilizer signal to be sent to the
body control module.
Remote Search Function
Determines if the remote is present inside the vehicle. When the remote is taken out of the vehicle, the gauge control module will show a warning.
Lighting and Indicator Function
The body control module controls the power switch light, displays information in the multi-information display (MID), and illuminates
the security indicators in the gauge control module.
Key Lockout Prevent Function
The body control module monitors whether or not there is the remote in the vehicle. If the remote is in the vehicle, the system will not
lock the doors. If the driver manually locks and closes the doors with the remote in the vehicle, the body control module energizes the
driver's door lock actuator and unlocks the driver's door. When the trunk is closed with the remote left in the trunk, the body control
module detects the location of the remote unit and does not lock the trunk.
Registration Facility
The body control module can store up to 6 remotes with the HDS.
Alarm Function
Detects if the doors are opened or closed with the vehicle in the ACCESSORY/ON mode. When the remote is taken out of the
vehicle, the keyless buzzer will sound and the gauge control module (only when the vehicle is in the ON mode) will show a warning.
Before the remote battery level falls to the point where the remote cannot be detected, the gauge control module will show a warning
and an alarm will sound.
Customer Emergency
When the power switch is pressed continuously at least three times or is held for 1.5 seconds or longer in an emergency while driving,
the vehicle will turn to the ACCESSORY mode, and the gear position/mode changes automatically to the N position/mode. When the
vehicle speed becomes slow, the gear position/mode automatically changes to the P position/mode, and the vehicle will turn to the
OFF (LOCK) mode.
Immobilizer Function
The immobilizer function provides mutual authentication between the body control module, the PCM, and the VSA modulator-control
unit when the vehicle is turned to the ON mode. The engine stays running after start-up if the immobilizer signal matches. The body
control module authenticates the VSA modulator-control unit and the immobilizer signal only one time when the vehicle is turned to
the ON mode after reconnecting the battery, removal and installation of the back-up fuse, or removal and installation of the VSA
modulator-control unit.
For some model*, the brake pedal must be depressed to perform the immobilizer authentication.

Panic Function
When you press the PANIC button on the remote, the body control module sounds the horn and activates the exterior lights.
Walk Away Auto Lock Function
The walk away auto lock function detects where the remote is and locks all doors on the vehicle when all the doors are closed and the
remote is outside of the vehicle and out of the range.
To operate the walk away auto lock system, it is necessary to enter the auto lock mode. To enter the auto lock mode, the following
conditions must be met:
- The vehicle is in the OFF (LOCK) mode.
- Any door is closed, and then all the doors become closed.
- The remote is outside and is within 1.5 m (5 ft) from the vehicle.
Once the system enters the auto lock mode, the vehicle's buzzer beeps sound once.
After the auto lock mode is engaged and the remote is away more than 1.5 m (5 ft) from the vehicle for 2 sec. or more, all the doors
become locked. At that time, the vehicle's buzzer beeps once and some exterior lights blink once to confirm that the walk away lock
system is engaged.
However, if the remote is within 1.5 m (5 ft) from the vehicle for 30 sec. or more, the doors automatically lock.
The walk away auto lock system does not work under the following conditions:
- The remote is inside of the vehicle.
- Any door is closed when the remote is more than 1.5 m (5 ft) away from the vehicle.
- Any door is opened after the auto lock mode is engaged.
The walk away auto lock system does not work and the vehicle's buzzer beeps under the following conditions:
- The remote is away more than 1.5 m (5 ft) from the vehicle while closing the door.
- A communication error occurs between the remote and the vehicle.
Remote Climate Control Operation
This function is used to operate the climate control unit remotely from outside the vehicle by using the remote. The remote climate
control operation is initiated by first pressing the lock button, then pressing and holding the AUTO A/C button on the remote within 5
sec. The A/C signal from the remote is received by the RF antenna and is sent from the body control module to the climate control
unit via the B-CAN to activate the climate control. The turn signal lights will blink to confirm that the vehicle condition has changed.
Pressing and holding the AUTO A/C button on the remote during the remote climate control operation stops the operation.
The remote climate control operation can be activated and deactivated under the following conditions.
Operation start conditions:
- Hood is closed.
- Brake pedal position switch is OFF.
- All door switches are OFF.
- Electric powertrain is normal.
- Climate control system is normal.
Operation stop conditions:
- Hood is opened.
- Brake pedal position switch is ON.
- Driver's door switch is ON.
- Electric powertrain is abnormal.
- Climate control system is abnormal.
If the above deactivation conditions are not met, climate control stops in 30 min. with timer control.
Failsafe Function
If there is a failure in the keyless access system that terminates the keyless access features, the system enters the failsafe mode and displays the keyless access indicator.
