Wireless Door Lock Control System (For Hatchback) -- 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 module set sub-assembly which sends radio waves to the door control receiver. The main body ECU performs an ID code identification process and engages the door lock control.

FUNCTION OF MAIN COMPONENTS

Component
Function
Door control transmitter module set sub-assembly
  1. Has lock, unlock, and panic switches.
  2. Transmits weak radio waves (recognition codes and function codes) to the door control receiver.
  3. Illuminates the indicator light (LED) during transmission.*2
Door control receiver
Receives weak radio waves from the door control transmitter module set sub-assembly and sends them to the main body ECU.
  1. Front door courtesy light switch assembly LH/RH
  2. Rear door courtesy light switch assembly LH/RH*1
  3. Back door courtesy switch
  1. Turns on when a door is opened and turns off when it is closed.
  2. Outputs door status signals (open or closed) to the main body ECU.
Unlock warning switch assembly
Detects if the key is inserted in the ignition key cylinder or not.
  1. Front door lock assembly LH/RH
  2. Rear door lock assembly LH/RH*1
  1. Built in motor locks or unlocks door.
  2. Transmits the door lock position 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. *1: for 5 Door
  2. *2: w/ Tire Pressure Warning System

SYSTEM FUNCTION
The door control transmitter module set sub-assembly has the lock, unlock, 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. Part of these functions can be customized (YARIS_NCP93 RM000004SEK005X.html).

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 wireless door lock control, all the doors will lock again automatically.
Answer back
  1. When the doors are locked by wireless operation, the hazard warning lights flash once.
  2. When the doors are unlocked by wireless operation, the hazard warning lights flash twice.
Panic alarm
Pressing the panic switch of the door control transmitter module set sub-assembly for longer than about 0.8 seconds causes the following alarms to activate:
  1. Sound the vehicle horn.
  2. Sound the security horn.*1
  3. Blinks the headlights, hazard warning lights and taillights.
  4. Illuminates the interior lights (when the switch is in the door position).
While the panic alarm is operating, pressing any switch of the door control transmitter module set sub-assembly cancels the alarm operation.
Illuminated entry
When all the doors are locked, pressing the unlock switch causes the interior lights to come on simultaneously with the unlock operation.
Self-diagnostic mode
The following are conditions to enter self-diagnostic mode:
  1. If the door control receiver receives normal radio waves from the door control transmitter module set sub-assembly when the system is in diagnostic mode, it flashes the interior lights in a normal pattern that corresponds to the function of each switch.
Transmitter recognition code registration
Enables registration (writing and storing) of door control transmitter module set sub-assembly recognition codes in the EEPROM that is contained in the door control receiver.
  1. *1: w/ Theft Deterrent 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 door control transmitter module set sub-assembly. 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 registered codes and disables the wireless door lock function.
This mode is used when the door control transmitter module set sub-assembly is lost.

CONDITIONS THAT WIRELESS FUNCTIONS DO NOT OPERATE

  1. Lock function will not operate when either of the following conditions is met:

    1. Any of the doors is open.
    2. The key is inserted in the ignition key cylinder.

  2. Unlock function will not operate when the following condition is met:

    1. The key is inserted in the ignition key cylinder.
