HINT:
Even in disarmed state, the indicator light flash. (Due to the sig-
nal output form immobilizer system). The indicator always
flashes receiving the signal from the immobilizer system at any
time in the arming condition.

(a) Transfer to active mode:
In each passive mode, when ºdisarmed state of active
mode " arming preparation transfer conditionº is met, the
active mode transfers to each condition. In this case, ac-
tive mode continues till disarmed state.

(b) Answer back:
The hazard lights flush as answer back under the follow-
ing conditions.
(1) When the system is set.
When arming preparation is set from disarmed state
using the wireless door lock, the hazard lights flush
once.
(2) When the system is released.
When disarmed state is set from either arming prep-
aration, armed state or alarm sounding using the
wireless door lock, the hazard lights flush twice.

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.
NoYe s
Only wireless function (Remote control) will not operate.
(If a new transmitter or a transmitter of the same type that works properly with the vehicle is not available.)

faulty.

Check the wave reaching range with another
transmitter (normal). When the range is normal,
transmitter defection is detected, the range is
not normal, wireless door lock receiver defection
is defected.
The wave reaching range check:
Is the wave reaching range normal?

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.
