Keyless Entry: Service and Repair

METHOD OF REGISTERING A SECRET CODE

Each individual secret code is registered inside the transmitter and so it is necessary to register these codes with the received in the following cases.
- When either the transmitter or receiver is replaced;
- If a second transmitter is to be used;
- If it appears that a problem is occurring because of faulty registration of a code.
A maximum of two different codes per transmitter can be stored in the memory area of the EEPROM, and up to two different transmitters can be used. When the codes for the first transmitter are registered, the previously-registered codes for both transmitters are cleared. Therefore, if you are using two transmitters or are adding a second transmitter, the codes for both transmitters must be registered at the same time.

1. Check that the door locking function works normally using the door key.




2. Connect the scan tool to the data link connector.

NOTE: This grounds the data link connector No.1 and gets ready for a code registration.

CAUTION: Turn the ignition switch to OFF before connecting or disconnecting the scan tool.

3. Close all doors.
4. Turn the ignition switch to ACC and return it to OFF.

NOTE: This locks and unlocks the door once, and then a code can be registered.

5. After pressing any switch on the transmitter once, press it two more times within 10 seconds to register the same code for SET I and SET II.
6. After registration is completed, the doors will automatically be locked and unlocked once.
7. If you are using two transmitters or have added a second transmitter, carry out the same registration procedure for the second transmitter within one minute after the registration mode has been set and registration of the code for the first transmitter has been completed. After the second registration is completed, the doors will automatically lock and unlock once.
8. Registration mode finishes under the following conditions.
- Registration of two transmitter codes are completed.
- One minute has passed since the registration mode setting.
- Scan tool is disconnected. (ground released.)
- Ignition switch is turned ON
- Any of the doors are opened.
