Keyless/Power Door Locks/Security System Description - Control/Function (5-door) (2017 2018 2019 2020 2021)
Door Lock Control
The door lock control function allows the body control module to detect the status of various switch signals and controls each actuator in order to lock and unlock the doors.
The system has three circuits between door lock actuators and the body control module to improve safety of the system. One is for the driver's door lock actuator, and others are for the left rear door lock actuator and passenger's side door lock actuators. The door lock actuator circuit has two fuses. When one fuse is blown, another fuse in the same circuit must be checked.
Tailgate Release Control
In the tailgate release function, the body control module activates the tailgate release actuator by the tailgate outer handle switch operation when the vehicle runs at a speed less than 1.2 mph (2 km/h). The tailgate can be unlocked by the tailgate outer handle switch operation without having the remote if all the doors are unlocked.
Keyless Door Lock Control
The keyless transmitter or the remote can transmit a lock or unlock signal to the immobilizer-keyless control unit or the body control module. The body control module then controls the door lock actuator by the B-CAN signal and various switch signals. The customization menu can also set the relock timer value.
Keyless Door Lock Control (Tailgate)
The keyless transmitter or the remote can transmit an unlock signal to the immobilizer-keyless control unit or the body control module. The body control module then activates the tailgate release actuator when the tailgate outer handle switch is operated.
Key Lockout Prevent Function
The body control module monitors whether or not there is a remote in the vehicle or if there is a key inserted to the ignition key cylinder. If the remote is in the vehicle or if the key is inserted to the ignition key cylinder, the system will not lock the doors. If the driver manually locks and closes the doors with the remote in the vehicle or if the key is inserted to the ignition key cylinder, the body control module energizes the driver's door lock actuator and unlocks the driver's door.
Automatic Door Lock/Unlock Control
The automatic door lock/unlock control function allows the body control module to detect the status of B-CAN signals and various switch signals and controls each actuator in order to automatically lock/unlock the doors.
Automatic Door Lock Function:
- When the vehicle speed exceeds 9 mph (15 km/h). (Default setting)
- When the shift position/mode is out of the P position/mode. (CVT)
Automatic Door Unlock Function:
- When the driver's door switch is ON (door open). (Default setting)
- When the vehicle mode is changed to the OFF (LOCK) mode from the ON mode.
- When the shift position/mode is moved to the P position/mode from other than P position/mode. (CVT)
Customizing Function:
The locking method can be set as non-link, link to vehicle speed, link to shift position/mode, or link to ignition switch or engine start/stop switch by the customizing function. For more information about customize options, refer to the Owner's manual.
Security Control
When the security alarm is set, the body control module sends the security set signal using the B-CAN.

Security Setting
When the security alarm is set, the body control module sends the security set signal using the B-CAN. When the gauge control module receives a security set signal from the body control module, the security indicator flashes at a slower pace to indicate the system has armed.
Security Alarm
With the security system armed, manually opening the hood, the tailgate, moving the door lock knob to the unlock position, or shifting to other than the P position/mode activates the security alarm. During activation, the security alarm sounds, the headlights low beam, the front parking lights, the taillights, the license plate light, and the side marker lights blink, repeating this alarm (one cycle is 120 seconds). Even if you remove the 12 volt battery, the alarming state cannot be changed. The alarm starts again when reinstalling the 12 volt battery.
Answer Back Control
When using the remote or the keyless transmitter, the body control module provides an answer back function to alert the customer that the body control module received a lock or unlock command. When the body control module receives a lock signal, the body control module outputs once to turn on the turn signal lights, and the horn or the keyless buzzer to sound. When the body control module receives an unlock signal, the body control module outputs two times to turn on the turn signal lights, and the horn or the keyless buzzer to sound.
When the body control module receives a lock signal, the body control module sends signals once to the turn signal lights, and the horn or the keyless buzzer will sound once when you press the lock button again within 5 seconds.
When the body control module receives an unlock signal, the body control module sends signals two times to the turn signal lights.
