REGISTRATION OF RECOGNITION CODE
Follow the flow chart to register the transmitter recognition code with the wireless door lock ECU.

HINT:
- If the prescribed conditions are not entered while registering the transmitter code, the wireless door lock ECU returns to normal operation.
- There are 4 modes: add mode, rewrite mode, confirmation mode and erase mode; the mode to use is decided after the recognition code is registered.
- If maximum of 4 recognition codes can be registered.

REFERENCE:
- The add mode is used to retain codes already registered while you register new recognition codes. However, if the number of registered codes exceeds 4 codes, previous registered codes are correspondingly erased in order, starting from the first registered code.
- The rewrite mode is used to erase all previous registered codes before registering new recognition codes. This mode is used before registering new transmitter or wireless door lock ECU.
- The confirmation mode is for confirming how many recognition codes are already registered before you register additional recognition codes.
- The erase mode is used to erase all registered codes and cancels the wireless door lock operation. Use this mode when the transmitter is lost.
