Toyota RAV4 Service Manual: Registration

Hint:

The key has 2 codes: the key code (immobiliser code) and the wireless code (recognition code). Both of these codes need to be registered. For wireless code registration procedures, refer to the following procedures (see page dl- 46). For key code registration procedures, refer to the procedures below.

1. Description of code registration

1. When adding master keys and sub-keys (additional registration).

1. Register the key codes in the transponder key ecu.

2. After replacing the transponder key ecu (new key code registration).

1. Register the key codes (immobiliser code) in the new transponder key ecu.

2. Register the ecu communication id between the ecm and the new transponder key ecu.

3. After replacing the ecm.

1. Reregister the ecu communication id between the new ecm and the transponder key ecu.

4. After replacing the transponder key ecu and ecm.

1. Register the ecu communication id between the new ecm and the new transponder key ecu.

5. Erasure of key codes.

1. Erase the key code(s) of the lost key(s).

2. New key code registration (procedure "b")

1. New key code registration

Condition:

No key codes are registered in the transponder key ecu.

Hint:

• In this mode, a maximum of 3 key codes for 2 master keys and 1 sub-key can be registered.

  The master keys and sub-key can be registered in any order because the transponder key ecu can distinguish between different types of keys.

• New key codes must be registered with the battery connected. The ignition switch can be either on or off.
• When a new transponder key ecu is installed, key codes must be registered in the transponder key ecu.

Hint:

• The new key code registration mode can be deliberately ended by following procedure a or b below when the battery is connected, and at least 1 key code for the master key has been registered.

1. Insert the key into the ignition key cylinder and turn the intelligent tester on.
2. Follow the instructions on the intelligent tester screen to end the new key code registration mode.
3. New key code registration mode ends.

• When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
• If the new key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister an already registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light. The output details are shown below.

3. Registration of additional key (procedure "a")

Hint:

• A maximum of 5 master key codes and 3 sub-key codes can be registered.
• Additional key code registration mode ends if each step is not completed within the specified time.
• When proceeding to the next step while the timer is running, the timer is reset and begins the countdown for the next step.
• When the ignition key cylinder or the ignition key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other keys.

Notice:

When the ignition key cylinder has been replaced, locking and unlocking doors are possible with the new master key once the transmitter module from the original master key has been transferred to it.

Keep the original master key. If the new master key's transmitter module battery fails, the original master key can be used to lock and unlock doors through the door key cylinder.

1. Additional key code registration

Condition:

At least one key code must be registered in the transponder key ecu.

Hint:

• If the key is removed within 60 seconds in step 6, the additional key code registration mode is canceled.
• A brief outline of the procedures for key code registration is shown above. For more detailed information, refer to the intelligent tester screen's instructions.
• When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
• If the additional key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister a previously registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light. The output details are shown in procedure "b".

4. Erasure of key code (procedure "d")

Hint:

All key codes are erased except for the master key, which is used for erasing the key codes. In order to use a key whose code has been erased, a new key code must be registered.

1. Erasure of key code

Condition:

At least two key codes must be registered in the transponder key ecu.

Hint:

• To cancel erasure mode after the erasure request is sent from the tester to the ecu, leave the master key inserted until the timer times out.
• A brief outline of the procedures for key code erasure is shown above. For more detailed information, refer to the intelligent tester screen's instructions.
• When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.

5. Ecu - ecm communication id registration (procedure "c")

Notice:

• The ecu communication id should be registered when the transponder key ecu and / or ecm is replaced in order to match the ecu - ecm communication id.
• The engine cannot be started unless the ecu - ecm communication id matches.
• Do not disconnect the battery while the ecu - ecm communication id is being set.
• Do not turn the ignition switch from on to off 20 times or more before setting the ecu - ecm communication id. If this operation is likely to be performed 20 times or more, disconnect the negative battery terminal cable in order to avoid engine start disablement. Failure to do so will result in the engine not starting unless the transponder key ecu is replaced with a new one.

1. After replacing the transponder key ecu

1. Register the key code(s) by following the new key code registration procedure (procedure "b").
2. Using sst, connect the tc and cg terminals of the dlc3 before inserting the key into the key cylinder.

Sst 09843-18040

3. Insert a previously registered key into the ignition key cylinder, turn the ignition switch on (do not start the engine), and leave it as is for 30 minutes.
4. Turn the ignition switch off and disconnect terminals tc and cg.
5. Start the engine.
6. Check that the engine starts and stays on for more then 3 seconds. The registration is complete.

2. After replacing the ecm.

1. Register the ecu - ecm communication id

3. After replacing the transponder key ecu and ecm

1. Register the key code(s) by following the new key code registration procedure (procedure "b").
2. Register the ecu - ecm communication id
