WIRELESS DOOR LOCK CONTROL SYSTEM REGISTRATION

Tech Tips


  • If replacing the door control transmitter or the door control receiver, register its recognition code to the body ECU.

  • The add mode is used to register new recognition codes while still retaining codes already registered. This mode is used when a new transmitter is added. If the number of registered codes exceeds 6, the previously registered codes will be erased in order, starting from the oldest registered code.

  • The rewrite mode is used to erase all the previously registered recognition codes in order to register all-new recognition codes. This mode is used when the transmitter or the door control receiver is replaced.

  • The confirmation mode is used to confirm how many recognition codes have already been registered before another recognition code is registered.

  • The prohibition mode is used to erase all the registered codes and disable the wireless door lock function. This mode is used when the transmitter is lost.

  • All of the following registration procedures must be performed in order.


  1. PROCEDURE FOR RECOGNITION CODE REGISTRATION


    1. The following conditions should be met before starting the procedure:


      • No key is in the ignition key cylinder.

      • Only driver side door is open.

    2. Insert the key into the ignition key cylinder, then pull it out (Procedure "A").

    3. Insert the key into the ignition key cylinder, then pull it out within 5 seconds after procedure "A" (Procedure "B").

    4. Close and open the driver side door twice.

    5. Insert the key into the ignition key cylinder, then pull it out within 40 seconds after procedure "B" (Procedure "C").

    6. Close and open the driver side door twice.

    7. Insert the key into the ignition key cylinder and close all doors within 40 seconds after procedure "C" (Procedure "D").

    8. Turn the ignition switch from the LOCK to the ON position and back to the LOCK position at approximately 1 second intervals according to the number of times shown in the table below.

      Number of ON-LOCK operations of ignition switch:
      Mode Selection Ignition Switch ON-LOCK Operation Ignition Key Position
      Add mode Once A01BCE8

      • A: Ignition switch position "ON"

      • B: Ignition switch position "LOCK"

      • T1: Approximately 1 second.
      Rewrite Mode Twice A01BFRB

      • A: Ignition switch position "ON"

      • B: Ignition switch position "LOCK"

      • T1: Approximately 1 second.
      Confirmation Mode 3 times A01BE5X

      • A: Ignition switch position "ON"

      • B: Ignition switch position "LOCK"

      • T1: Approximately 1 second.
      Prohibition Mode 5 times A01BAOM

      • A: Ignition switch position "ON"

      • B: Ignition switch position "LOCK"

      • T1: Approximately 1 second.

    9. Remove the key from the ignition key cylinder within 40 seconds after the procedure "D" (Procedure "E").

    10. The body ECU automatically performs power door LOCK-UNLOCK operations to indicate which mode has been selected.

      Tech Tips

      If the number of ON-LOCK operations of the ignition switch is 0, 4 or 6 or more, there will be no response (power door LOCK-UNLOCK operation).

      Response to selected mode (Power door lock operation):
      Mode Selection Power Door Lock LOCK-UNLOCK Door Lock Status
      Add mode 1 cycle A01BCDK

      • A: Door lock motor status "LOCK"

      • B: Door lock motor status "UNLOCK"

      • E: 1 cycle

      • T1: Approximately 1 second
      Rewrite Mode 2 cycles A01BH4L

      • A: Door lock motor status "LOCK"

      • B: Door lock motor status "UNLOCK"

      • E: 1 cycle

      • T1: Approximately 1 second
      Confirmation Mode The number of registered codes (1 to 4 cycles) A01BFPN

      • A: Door lock motor status "LOCK"

      • B: Door lock motor status "UNLOCK"

      • C: 1st time

      • D: 2nd time

      • E: 1 cycle

      • T2: Approximately 2 seconds
      Prohibition Mode 5 cycles A01BCXX

      • A: Door lock motor status "LOCK"

      • B: Door lock motor status "UNLOCK"

      • E: 1 cycle

      • T1: Approximately 1 second

      Tech Tips


      • In confirmation mode, LOCK-UNLOCK operation will occur once for each recognition code that has been registered. For example, if 2 recognition codes have been registered, LOCK-UNLOCK movement will occur twice.

      • In confirmation mode, if no recognition codes have been registered, LOCK-UNLOCK operation will occur 11 times.

      Mode Selection Procedure
      Add Mode Continued on next step.
      Rewrite Mode
      Confirmation Mode Registration procedures are completed.
      Prohibition Mode

    11. Press both LOCK and UNLOCK switches on the transmitter simultaneously for 1 second or more. (Procedure F)

    12. Press either LOCK or UNLOCK switch for 1 second or more within 45 seconds after performing procedure E.

    13. The body ECU automatically performs power door LOCK-UNLOCK operations to indicate whether registration has been completed correctly.

      Response to registration completion:
      Power Door Lock LOCK-UNLOCK Operation Result Door Lock Status
      1 cycle Registration of recognition code has been completed. A01BCDK

      • A: Door lock motor status "LOCK"

      • B: Door lock motor status "UNLOCK"

      • E: 1 cycle

      • T1: Approximately 1 second
      2 cycles Registration of recognition code has failed. A01BH4L

      • A: Door lock motor status "LOCK"

      • B: Door lock motor status "UNLOCK"

      • E: 1 cycle

      • T1: Approximately 1 second

      Tech Tips

      If registration of recognition code has failed, perform registration procedures again from the beginning.

      Next step
      Next Operation Procedure
      Another transmitter needs to be registered. Return to procedure "F" within 40 seconds (*1).
      Finish registration procedure. Continued on next step.

      Tech Tips

      *1: All 6 recognition codes can be registered consecutively.

    14. Perform either of the following:


      • Open a door.

      • Insert the key into the ignition key cylinder.

    15. Registration of recognition codes (add mode and rewrite mode) is completed.
