Wireless Door Lock Control System (For Non-Built-In Type Door Control Receiver) -- System Description |
| WIRELESS DOOR CONTROL SYSTEM DESCRIPTION |
This system locks and unlocks the vehicle's doors remotely. The wireless control system has the following features:
- The door control receiver performs the code identification process and the driver side junction block (integration relay) operates the door lock control. A serial data link is provided for communication between the receiver and junction block.
- A key-integrated type transmitter is used and it contains the following 2 switches: the door lock switch, door unlock switch.
- An LED is built into the transmitter so that the battery status can be checked.
- The door control receiver performs the code identification process and the driver side junction block (integration relay) operates the door lock control. A serial data link is provided for communication between the receiver and junction block.
| FUNCTION OF MAIN COMPONENTS |
| Components | Functions |
| Door control transmitter |
|
| Unlock warning switch | Detects if key is in ignition key cylinder or not |
| Front door courtesy light switch Rear door courtesy light switch Back door courtesy light switch | Turns ON when door is open and turns OFF when door is closed. Outputs door status (open or closed) to driver side junction block (integration relay). |
| Front door lock Rear door lock Back door lock | Transmits door lock positions of each door to driver side junction block (integration relay) |
| SYSTEM FUNCTION |
Door lock / unlock function:
- With no key in the ignition key cylinder (unlock warning switch is OFF) and all door courtesy light switches OFF, pressing the door control transmitter's LOCK / UNLOCK switch causes the transmitter to output faint electric waves. The transmitter will send a faint electrical wave to the door control receiver. The high frequency circuit built into the door control receiver demodulates the wave into code data, computes the data, and compares the data with previously registered ID codes. If the data is verified, a door lock / unlock request signal is output to the driver side junction block (integration relay). When the request signal is received, the junction block outputs a door lock / unlock control signal to each door lock. Each door lock then locks / unlocks its respective door and turns ON / OFF its door lock position switch according to the signal.

Answer-back function:
- The driver side junction block (integration relay) receives the door unlock detection switch's ON / OFF signals and uses these signals to confirm if the door control operation has completed. The junction block then outputs the hazard warning light's output control signals to flash the hazard warning lights as an answer-back.

The wireless door lock control system has the following functions.
Function Outline All door lock function Pressing LOCK switch locks all doors All door unlock function Pressing UNLOCK switch unlocks all doors Answer-back function Hazard warning lights flash once when doors are locked, and flash twice when doors are unlocked to indicate that operation has been completed Automatic locking function If no doors are opened within 30 seconds after they are unlocked by wireless transmitter, all doors will lock again automatically Illuminated entry function If locked doors are unlocked through wireless operation, ignition key cylinder light and dome light illuminate. If one of following situations occurs, lights will fade out: - Within 15 seconds, doors are not opened and doors are locked through wireless operation
- Within 15 seconds, key is inserted in ignition key cylinder and ignition switch is turned ON
- No operations or actions are performed for 15 seconds
Security function Sends signal as rolling code Transmitter recognition code registration function Enables 4 modes for registering (writing and storing) transmitter recognition codes in EEPROM, which is built into door control receiver - Within 15 seconds, doors are not opened and doors are locked through wireless operation
