IMMOBILIZER SYSTEM
Standard key registration:
A standard key should be registered or the other standard key should be re-registered when a reg-
istered standard key has been lost. The standard keys must be re-registered when the immobilizer
unit or ECU has been replaced and the code re-registering key has been re-registered.
NOTE:
Do not start the engine with a standard key that has not been registered.
If the main switch is set to ON with a standard key that has not been registered, the immobilizer
system indicator light flashes to indicate malfunction code 52. (Refer to SELF-DIAGNOSIS MAL-
FUNCTION CODES.)
1. Check that the immobilizer system indicator light flashes to indicate the standby mode. To acti-
vate the standby mode, set the main switch to OFF. The standby mode will be activated after 30
seconds. The indicator light stops flashing after 24 hours and the standby mode ends.
2. Using the code re-registering key, set the main switch to ON, then to OFF, and then remove
the key within 5 seconds.
3. Insert the standard key to be registered into the main switch, and then set the main switch to
ON within 5 seconds to activate the key registration mode.
NOTE:
If the two standard key codes are stored in memory, they will be erased when the key registration
mode is activated. When the key registration mode is activated, the immobilizer system indicator
light flashes rapidly (i.e., off for 0.5 second and on for 0.5 second).
4. While the indicator light is flashing, set the main switch to OFF, remove the key, and then insert
the second standard key to be registered into the main switch within 5 seconds.
NOTE:
If the immobilizer system indicator light stops flashing 5 seconds after the first standard key is regis-
tered, the registration mode is complete. If this occurs, the second standard key cannot be regis-
tered, therefore, repeat steps 2 to 4 to register both standard keys.
5. Set the main switch to ON.
NOTE:
When the indicator light goes off, registration is complete.
