(1) Conditions that cause the panic alarm control to set
off the panic alarm:
The panic alarm control sets off the panic alarm by
pressing the PANIC switch on the wireless transmit-
ter under the following conditions.
The ignition switch is OFF.
The theft deterrent system is not in the alarm
sounding state (common to active arming
mode and passive arming mode).
The panic alarm control is not operating (the
alarm is not set off).
(2) Conditions that cause the panic alarm control to
shut off the alarm:
The panic alarm control shuts off the panic alarm
when any of the following conditions is met during
panic alarm operation.
The ignition switch is turned ON.
Any of the switches on the wireless transmit-
ter (PANIC/LOCK/UNLOCK) is pressed.
The panic alarm ends (60 seconds have
passed).
The theft deterrent system switches to the
alarm sounding state (common to active arm-
ing mode and passive arming mode). Condi-
tions for canceling the panic alarm are the
same as for the alarm control.
HINT:

6. SWITCH TO THE ACTIVE ARMING MODE
HINT:
In each state of the passive arming mode, when the switch
condition transferring to active arming mode (disarmed state of
active arming mode " arming preparation state of active arm-
ing mode) is satisfied, the system will switch to each state of the
active arming mode. In this case, the active arming mode will
continue until the system switches to the disarmed state.

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 detected.
The wave reaching range check:
Is the wave reaching range normal?
(1 M area around vehicle)
(While the transmitting switch is pressed,
(approx. 20 secs.) the buzzer chirps continuously.
After 20 secs., repress the switch again.)

INSPECTION
1. INSPECT WIRELESS DOOR LOCK TRANSMITTER
OPERATION
HINT:
Refer to ºWireless door lock control transmitter battery replace-
mentº on page BE±103.
(a) Using a screwdriver, remove the cover.
(b) Remove the battery (lithium battery).
(c) Install a new or normal battery (lithium battery).
HINT:
When a new or normal battery can not be obtained, connect 2
new 1.5 V batteries in series, connect the battery (+) to the bat-
tery receptacle side terminal and the battery (±) to the bottom
terminal, then apply 3 V voltage to the transmitter.
(d) In the location where transmitter is approx. 1 M away from
the driver's outside handle in the right direction, check
transmitter operation while pressing transmission switch
on the side of the transmitter body.
Standard:
Remote control of the vehicle door lock can be operated.
HINT:

The minimum operation distance differs according to op-
erator, the way of holding the transmitter, and location.

As a weak wave is used, operating distance might be
shortened when noise is detected in a strong wave or a
used frequency.
(e) Install the battery (lithium battery).
(f) Install the cover so that a rubber cover is not distorted or
slipped off.
