Make the vehicle in the initialized condition:
The initialized condition is the condition when the following conditions are satisfied.
(1) Key plate has not been inserted in the ignition key cylinder.
(2) All the doors are closed. (Door warning light is off.)
(3) All the doors are locked.
Under the standard operation, when repeating the operation of UNLOCK and LOCK switch
3 times or more alternately, check the UNLOCK±LOCK operation from 3rd time onward.

Following procedures are standard operation.
(1) Keep about 1 M away to the right direction from the outside handle of a driver's seat.
(2) Face the transmitter toward the vehicle and press one of transmitter switches for about 1 sec.
Normal


Operative distance may differ according to
an operator, the way of holding the transmitter
or position.

Because weak electric wave is used, when
there is strong wave or noise in the used
frequency ,operation distance might be
shortened.

PRE±CHECK

Replace the transmitter battery with a new or normal
one and check UNLOCK±LOCK function works under
the standard operation.


The battery should be replaced by only the shops with
sufficient skill as new normal battery is necessary.

Battery quality can be judged by checking the rem-
nant volume of the battery.

HYBRID VEHICLE IMMOBILISER SYSTEM
REGISTRATION PROCEDURE
1. THE COMMUNICATION BETWEEN THE HYBRID VEHICLE CONTROL ECU AND THE TRANS-
PONDER KEY ECU IS AS FOLLOWS
(a) When the ignition is turned ON, the transponder key ECU checks if the key is pre±registered or not
and sends the check result to the hybrid vehicle control ECU.
(b) When the hybrid vehicle control ECU confirms that the key is pre±registered, it transmits its own ID
(random numbers) to the transponder key ECU.
(c) Receiving the ID, the transponder key ECU calculates internally and sends the calculated result back
to the hybrid vehicle control ECU.
(d) The hybrid vehicle control ECU rechecks the calculation inside the ECU.
When the calculation result corresponds to its own ID, this enables the engine to start.
2. PREASE DO THE FOLLOWING PROCEDURES WHEN YOU EXCHANGE TRANSPONDER KEY
ECU
HINT:
When replacing the transponder key ECU or hybrid vehicle control ECU, start the engine after leaving it for
more than 30 minutes with the ignition switch ON position.
(a) (Case 1):
Replace the transponder key ECU. "Register the new transponder key codes. "Leave more than
30 minutes with the ignition switch ON. "Start the engine.
(b) (Case 2):
Replace the hybrid vehicle control ECU. "Leave more than 30 minutes with the ignition switch ON.
"Start the engine.
(c) (Case 3):
Replace the transponder key ECU and hybrid vehicle control ECU. "Register the new transponder
key codes. "Start the engine.
3. IF ALL KEYS ARE LOST, OBSERVE THE FOLLOWING
(a) Purchase a new transponder key ECU and a new key.
(b) Replace the transponder key ECU with new one.
(c) Insert a new key into the key cylinder, turn the ignition switch ON and leave it as it is for 30 min.
4. SETTING HYBRID VEHICLE IMMOBILISER SYSTEM
(a) Removing a key from the key cylinder sets hybrid vehicle immobiliser system.
(b) When 20 sec is elapsed after the key is turned from ignition switch ON to ACC or LOCK, the hybrid
vehicle immobiliser is set.
5. UNSETTING HYBRID VEHICLE IMMOBILISER SYSTEM
Insert a key into the key cylinder
(Under this condition, transponder key ECU starts communication with the transponder chip built in the key.
When the ID code in the chip coincides with that registered in ECU consecutively 2 times, the hybrid vehicle
immobiliser system is reset).

Security indicator is flashing
Insert a master key (black) into the key cylinder.

Insert the other master key (black) into the key cylinder.
Insert the sub key (gray) into the key cylinder.
Security indicator goes off for 1 sec. and then lights up again.

6. KEY REGISTRATION IN AUTOMATIC REGISTRATION MODE
(a) Registration of a new transponder key.
HINT:

This must be done when you install a new transponder key ECU.

It is possible to register up to 2 master key codes and a sub key code.

In the automatic registration mode, the last key registered becomes sub±key.
(b) Initial condition: Battery connected, no key in key cylinder.

HINT:

When a key is not inserted in the key cylinder on the automatic registration mode, the security indicator
always lights on.

When the immobiliser system operates normally and the key is pull out, the security indicator blinks.

When key code registration could not be performed on the automatic registration mode, code 2±1 is
output from the security indicator and when inserting the already registered key, code 2±2 is output.
(c) Automatic registration mode completion
If completing the mode forcibly when more than 1 key code have been registered on the automatic
registration mode, perform the following procedures.
After 1 more key code have been registered with master key, turn the ignition switch from LOCK to ON
5 times within 10 secs. after inserting the already registered key or without pulling the key out.
