2. REGISTRATION OF RECOGNITION CODE 

   HINT:

   • The add mode is used to retain already registered codes while registering new recognition codes. This mode is used when adding a transmitter. If the number of registered codes exceeds 4, previously registered codes will be correspondingly erased in order, starting from the first registered code.
   • The rewrite mode is used to erase all the previously registered codes and register only new recognition codes. This mode is used when exchanging the transmitter or the door control receiver for new one.
   • The prohibition mode is used to erase all the registered codes and cancel the wireless door lock function. Use this mode when the transmitter is lost.
   • The confirmation mode is used to confirm how many recognition codes have already been registered before an additional registration of a recognition code.
   1. The vehicle should be in the following conditions.
      1. The key is not inserted in the ignition key cylinder.
      2. The driver's door is opened (The other doors are closed).
      3. The driver's door is unlocked.
   2. Perform the followings in order.
      1. Insert and remove the key from the ignition key cylinder twice within 5 seconds.
      2. Close and open the driver's door twice within 40 seconds. Then insert the key into the ignition key cylinder and remove it.
      3. Close and open the driver's door twice within 40 seconds. Then insert the key into the ignition key cylinder and close the door.
      4. Turn the ignition switch from LOCK to ON and back to LOCK at approximately 1 second interval 1 to 5 times to select the mode. Then remove the key from the ignition key cylinder.

         NOTE: If the number of the ON-LOCK operation of the ignition switch is 0, 4 or 6 or more, the registration will finish without any signs.
      5. Check that the MPX body ECU automatically performs the LOCK-UNLOCK operation within 3 seconds to inform the operator of a selected mode.

         HINT:

         In the confirmation mode as shown in the illustration, when the LOCK-UNLOCK operation is performed twice, it means that 2 types of recognition codes are registered.

         NOTE: In the confirmation mode, if the number of the registration code is 0, the ON-LOCK operation is automatically performed 5 times.

         HINT:

         If the prohibition mode and confirmation mode are selected, the registration of the recognition code is completed at this time.

   3. Register a transmitter.
      1. Within 40 seconds after the add mode or the rewrite mode has been selected, press the LOCK and UNLOCK switches on the transmitter simultaneously for 1.0 - 1.5 seconds.
      2. Within 3 seconds, press either one of the switches for more than 1.0 second.
      3. Within 3 seconds, the LOCK-UNLOCK operation will be automatically performed once if the registration of the recognition code of the transmitter has been completed correctly. If the LOCK-UNLOCK operation is performed twice, the registration of the recognition code has failed. Perform the registration procedure from the beginning once again.
