IMMOBILIZER SYSTEM

ELEC

NOTE:

KEY ID REGISTRATION METHOD

Initially one code re-registering key and two standard keys have been registered with the immobilizer

system.

In the course of use, you may encounter the following case where re-registration of code re-register-

ing/standard key is required.

Code re-registering key registration:

When the immobilizer unit or ECU, failed and the unit was replaced, the unit cannot be used until the

key ID is registered because it is not registered to the unit.

a. As usual steps, when the main switch is turned “ON”, the immobilizer system indicator light goes on

for about one second.

b. If the immobilizer system indicator light goes off, it shows that the code re-registering key registra-

tion is finished.

c. Check that the engine can be started.

d. Consequently, carry out the standard key registration, according the section below.

Standard key registration:

When you lost a standard key and need a new one. Or when the code re-registering key is re-registered

after the immobilizer unit or the ECU, are replaced.

a. Check that the immobilizer system indicator light shows the standby mode.

To initiate the standby mode, turn “OFF” the main switch and then it will be the standby mode when it

passes 30 seconds. When 24 hours passed, the standby mode ends and the immobilizer system

indicator light stops flashing.

b. After the main switch is turned “ON” with the code re-registering key, within 5 seconds, turn “OFF”

the main switch and then turn “ON” the main switch with the standard key (the first new key) that you

want to register.

c. It becomes the key registration mode and two standard key IDs that have been stored in the memory

are erased and the first new standard key ID will be registered. At this time, the indicator light quickly

blinks (“OFF” for 0.5 sec. and “ON” for 0.5 sec.).

d. In the condition as mentioned above (while the immobilizer system indicator light continues quick

flashing), after the main switch is turned “ON” with the first new standard key, turn “OFF” the main

switch within 5 seconds, and then turn “ON” the main switch with the standard key that you want to

Fast flashing goes off when it elapses 5 seconds and the registration mode is finished. In this case, the

second standard key cannot be registered and only the first standard key is registered.
