IMMOBILIZER SYSTEM
8-65
Standby mode
Standard key registration:
Standard key registration is required when a standard key is lost and needs to be replaced, or when
the code re-registering key is re-registered after the immobilizer unit or ECU are replaced.
TIP
Do not start the engine with a standard key that has not been registered. If the main switch is turned
“ON” with a standard key that has not been registered, the immobilizer system indicator light flashes to
indicate fault code “52”. (Refer to “SELF-DIAGNOSIS FAULT CODE INDICATION” on page 8-67.)
1. Check that the immobilizer system indicator light signals the standby mode.
2. Using the code re-registering key, turn the main switch to “ON”, then “OFF”, and then remove the
key within 5 seconds.
3. Insert the first standard key to be registered into the main switch, then turn the key to “ON” within 5
seconds to activate the key registration mode.
TIP
The existing standard key code is erased from the memory when the key registration mode is activated.
When the key registration mode is activated, the immobilizer system indicator light flashes rapidly.
4. While the indicator light is flashing, turn the main switch to “OFF”, remove the key, and within 5 sec-
onds, insert the second standard key to be registered into the main switch.
TIP
If the immobilizer system indicator light stops flashing 5 seconds after the first standard key is regis-
tered, the registration mode is deactivated. If this occurs, the second standard key cannot be registered,
and steps 2 to 4 need to be repeated to register both standard keys.
5. Turn the main switch to “ON”.
TIP
When the indicator light goes off, the registration is complete.
6. Check that the engine can be started with the two registered standard keys.
a. Main switch “ON”
b. Main switch “OFF”
c. LED on
d. LED off e. Standby mode on
f.
Standby mode off
