System Description
- WIRELESS DOOR LOCK CONTROL SYSTEM
The wireless door lock control system functions to lock and unlock all the doors from a distance. The system is controlled by a door control transmitter which sends radio waves to the door control receiver. The main body ECU performs an ID code identification process and engages the door lock.
- FUNCTION OF MAIN COMPONENTS
Component Function Door control transmitter - Has LOCK, UNLOCK, POWER BACK DOOR*1, POWER SLIDE DOOR RH*2, POWER SLIDE DOOR LH*2 and PANIC switches.
- Transmits weak radio waves (recognition codes and function codes) to the door control receiver.
- Illuminates the indicator light (LED) during transmission.
Door control receiver Receives weak radio waves (recognition codes and function codes) and outputs them as code data to the main body ECU. - Front door courtesy switch LH/RH
- Rear door courtesy switch LH/RH
- Back door courtesy switch
Turns on when a door is opened and turns off when it is closed. Outputs door status signals (open or closed) to the main body ECU. Unlock warning switch Detects if the key is inserted in the ignition key cylinder or not. Door unlock detection switch Transmits the door lock positions of each door to the main body ECU. Main body ECU Sends wireless door lock control signals in response to the code data from the door control receiver and signals from each switch. *1: w/ Power Back Door System

- SYSTEM FUNCTION
The door control transmitter has the LOCK, UNLOCK, POWER BACK DOOR*1, POWER SLIDE DOOR RH*2, POWER SLIDE DOOR LH*2 and PANIC switches. Operating these switches activates each function.
The wireless door lock control system has the following functions:
HINT:
The default settings of the following functions are on. Some of these functions can be customized. Refer to CUSTOMIZE PARAMETERS .
Function Operation All door lock Pressing the LOCK switch locks all doors. All door unlock
(Unlock 2 operation)Pressing the UNLOCK switch twice within 3 seconds unlocks all the doors after the driver door is unlocked. Automatic lock If none of the doors is opened within 60 seconds after they are unlocked by the wireless door lock control, all the doors will lock again automatically. Power back door open/close operation*1 Pressing the POWER BACK DOOR switch of the transmitter for longer than about 0.8 seconds opens or closes the back door. Power slide door open/close function*2 Pressing the POWER SLIDE DOOR RH/LH switch of the transmitter for longer than about 0.8 seconds opens or closes the power slide door RH/LH. Answer back - When the doors are locked by wireless operation, the hazard warning lights flash once and wireless door lock buzzer sounds once.
- When the doors are unlocked by wireless operation, the hazard warning lights flash twice and wireless door lock buzzer sounds twice.
Panic alarm Pressing the PANIC switch of the transmitter for longer than about 0.8 seconds causes the following alarms to activate: - Sounds the horn.
- Flashes the headlights, taillights and hazard warning lights.
- Illuminates the interior lights (when the switch is in the DOOR position).
While the panic alarm is operating, pressing any switch of the transmitter cancels the alarm operation.Door ajar warning The buzzer sounds when the LOCK switch is pressed when any of the doors are ajar, and it sounds for 10 seconds continuously. The buzzer stops when all doors are closed or the UNLOCK switch is pressed. Illuminated entry When all the doors are locked, pressing UNLOCK switch causes the interior lights to come on simultaneously with the unlock operation. Self-diagnostic mode The following are conditions to enter the self-diagnostic mode: - If the door control receiver receives normal radio waves from the door control transmitter when the system is in diagnostic mode, it flashes the interior lights and sounds the wireless door lock buzzer in a normal pattern that corresponds to the function of each switch.
- Read DTCs using the Techstream.
Transmitter recognition code registration Enables the registration (writing and storing) of transmitter recognition codes in the EEPROM that is contained in the door control receiver. *1: w/ Power Back Door System
*2: w/ Power Slide Door System
- TRANSMITTER RECOGNITION CODE REGISTRATION FUNCTION
The table below shows the 4 ID registration function modes. The codes are electronically registered (written and stored) in the EEPROM that is contained in the door control receiver.
Mode Function Add mode Adds a newly received code while preserving any previously registered codes.
This mode is used when adding a new transmitter. If the maximum registration number is exceeded, the oldest one is cleared first.Rewrite mode Clears all previously registered codes and registers only newly input codes. Confirmation mode Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist. Prohibition mode Deletes all the registered codes and disables the wireless door lock function.
This mode is used when the transmitter is lost. - CONDITIONS THAT WIRELESS FUNCTIONS DO NOT OPERATE
- Lock function will not operate when either of the following conditions is met:
- Any of the doors is open.
- The key is inserted in the ignition key cylinder.
- Unlock function will not operate when the following condition is met:
- The key is inserted in the ignition key cylinder.
- Lock function will not operate when either of the following conditions is met:
