Keyless/Power Door Locks/Security System Description - Control/Function (2/4-door)

Door Lock Control 

The door lock control function allows the body control module to detect the status of various switch signals and control 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.

Trunk Lid Control 

The trunk lid control function allows the body control module to detect the status of various switch signals and control the trunk lid release actuator in order to lock and unlock the trunk.

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, then the body control module controls the door lock actuator by the B-CAN signal and various switch signal. The customization menu can also set the relock timer value.

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.

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.

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 trunk, moving the door lock knob to the unlock position, or shifting to other than the P position/mode activates the security alarm. Alternatively, 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, the body control module provides an answer back function to alert the customer that the body control module received a lock or unlock command from the remote or the immobilizer-keyless control unit. 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.
