Programming and Relearning
REGISTRATION PROCEDUREHINT: If you lose all the registered master keys, you cannot register or delete additionally. Change the transponder key ECU and then register new key codes by following the registration procedure in the automatic registration mode below.
1. KEY REGISTRATION IN AUTOMATIC REGISTRATION MODE
a. Registration of a new transponder key
HINT:
- This procedure must be done when you install a new transponder key ECU.
- The new transponder key ECU is in automatic key code registration mode. The key codes already fixed for this transponder key ECU can be registered. For this type of vehicle, up to 3 key codes can be registered.
- In the automatic registration mode, the last key registered becomes a sub key.
HINT:
- When a key cannot be inserted in the key cylinder in automatic registration mode, the security indicator always comes on.
- When the immobilizer system operates normally and the key is pulled out, the security indicator blinks.
- When key code registration could not be performed in automatic registration mode, code 2-1 is output from the security indicator. When the registered key is inserted, code 2-2 is output.
b. Automatic registration mode completion
If the mode is completed forcibly when more than 1 key codes are registered in automatic registration mode, perform the following procedure:
After more than 1 key codes are registered with the master key, turn the ignition switch LOCK "ON 5 times within 10 seconds using the already registered key.
2. REGISTRATION OF ADDITIONAL MASTER KEY AND SUB KEY
Do this operation to register an additional master key and sub key.
- *1: Insert the master key into the key cylinder. Turn the ignition switch to the LOCK " ON " LOCK position 5 times and back to LOCK within 15 seconds.
- *2: Open and close the driver's door 6 times within 20 seconds after completion of the previous operation.
- *3: Remove the master key from the key cylinder and insert another key to be registered in the key cylinder within 10 seconds after completion of the previous operation.
- *4: If 60 seconds or more elapse after the ignition switch is turned to the ON position, then key registration will be completed.
- *5: If 10 seconds or more elapse after removal of the key or opening and closing the driver's door, then key registration will be completed.
- *6: To register another key, insert the key to be registered in the key cylinder.
HINT:
- It is possible to register up to 4 master key codes including the registered key code.
- It is possible to register up to 2 sub key codes including the registered key code.
- When any operation time described above is over, the registration mode will be complete.
- When the next procedure is performed while the timer is working, the timer stops counting time, then the next timer starts.
3. ERASURE OF TRANSPONDER KEY CODE
Do this operation to erase the transponder key registration codes from the transponder key ECU.
HINT: All of the key codes except the master key code which is used for erasing the key codes are erased. In order to use a key for which the code has been erased, it is necessary to register the key code again.
HINT:
- When any operation time described above is over, the registration mode will be complete.
- When the next procedure is performed while the timer is working, the timer stops counting time, then the next timer starts.
4. ECU COMMUNICATION ID REGISTRATION
NOTE:
- The ECU communication ID should be registered when the transponder key ECU and/or the ECM is replaced, in order to match the ECM COMMUNICATION ID.
- The engine cannot be started unless the ECM COMMUNICATION ID matches.
a. Register the ECU communication ID.
1. After the transponder key ECU and/or the ECM is replaced, turn the ignition switch ON (the engine is not running).
2. Short the Tc and CG terminals of the DLC3 and leave them as they are for 30 minutes.
3. Check that the engine starts.
