Wireless Door Lock Control System (W/O Entry And Start System) -- 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 hand-held 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 control.

FUNCTION OF MAIN COMPONENTS

Component
Function
Door control transmitter
  1. Has LOCK, UNLOCK, and LUGGAGE OPEN switches.
  2. Transmits weak radio waves (recognition codes and function codes) to the door control receiver.
  3. 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.
  1. Front door courtesy light switch
  2. Rear door courtesy light switch
  3. Luggage compartment door courtesy light switch
Turns on when a door is opened and turns off when it is closed. Outputs door status codes (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 lock position 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.

SYSTEM FUNCTION
The door control transmitter has LOCK, UNLOCK, and LUGGAGE OPEN 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 (CAMRY_ACV40 RM0000011EV008X.html).

Function
Operation
All door lock
Pressing the LOCK switch locks all doors.
All door unlock
Pressing the UNLOCK switch locks all doors.
Automatic lock
If none of the doors is opened within 30 seconds after they are unlocked by the wireless door lock control, all the doors will lock again automatically.
Luggage compartment door opener
Pressing the LUGGAGE OPEN switch of the transmitter opens the luggage compartment door.
Power window and sliding roof * open
Pressing the UNLOCK switch for 2.4 seconds or more opens driver's side power window and sliding roof*.
Power window and sliding roof * close
Pressing the LOCK switch for 2.4 seconds or more closes driver's side power window and sliding roof*.
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.
Illuminated entry
When all the doors are locked, pressing UNLOCK causes the interior lights to come on simultaneously with the unlock operation.
Self-diagnostic mode
The following are ways to enter the self-diagnostic mode:
  1. 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 light in a normal pattern that corresponds to the function of each switch.
  2. Read DTCs with the intelligent tester.
Transmitter recognition code registration
Enables the registration (writing and storing) of 6 types of transmitter recognition codes in the EEPROM that is contained in the door control receiver.
HINT:
*: with sliding roof

TRANSMITTER RECOGNITION CODE REGISTRATION FUNCTION
The table below shows the 6 ID registration function modes by which up to 6 different codes can be registered. 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 number of registered codes exceeds 6, the oldest registered code is erased first.
Rewrite mode
Erases 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

  1. Lock operation is not available when:

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

  2. Unlock operation is not available when:

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

  3. Luggage compartment door opener is not available when:

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