TD–8THEFT DETERRENT – THEFT DETERRENT SYSTEM
TD
5. ALARM MEMORY FUNCTION
(a) If the alarm is set off (tampering is detected) while
the theft deterrent system is armed, it will be
recorded by the alarm memory function. Whenever
you cancel the theft deterrent system, the alarm
memory function causes the taillights to light up for
2 seconds in order to inform you that the alarm has
been set off.
(1) Conditions of the alarm memory function that
cause the taillights to light up:
When the theft deterrent system has entered
into the alarm sounding state (tampering has
been detected) even once, the taillights will light
up for 2 seconds if any of the following
conditions is met.
• Switched to the disarmed state from the
armed state during active arming mode.
• Switched to the disarmed state (1) from the
armed state during passive arming mode.
HINT:
Active arming mode: See ACTIVE ARMING
MODE.
Passive arming mode: See PASSIVE ARMING
MODE.
6. PANIC ALARM CONTROL
(a) The panic alarm control makes it possible to
voluntarily set off the panic alarm by pressing the
PANIC switch on the wireless transmitter.
(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
transmitter for over 2, 4 seconds under the
following conditions:
• The ignition switch is OFF.
• The theft deterrent system is not in the alarm
sounding state. (This condition is common
both to active arming mode and to passive
arming mode.)
(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.
• Either of the switches on the wireless
transmitter (LOCK/UNLOCK) is pressed.
• The panic alarm ends (60 sec. have passed).

• The theft deterrent system switches to the
alarm sounding state. Under this condition,
the theft deterrent system is controlling the
alarm rather than the panic alarm control. In
order to cancel this alarm, refer to the theft
deterrent system alarm sounding state
cancellation procedure. (This condition is
common both to active arming mode to
passive arming mode.)
HINT:
Active arming mode: See ACTIVE ARMING
MODE.
Passive arming mode: See PASSIVE ARMING
MODE.
7. SECURITY INDICATOR OUTPUT
(a) The multiplex network body ECU outputs a signal to
light up the security indicator, according to the state
of the theft deterrent system. However, some of the
actual lighting conditions of the security indicator
are different from the output signals of the multiplex
network body ECU.
Output:
Blinking cycle:
HINT:
• *: The above condition is common both to active
arming mode and to passive arming mode.
• When the immobiliser system is set, the security
indicator blinks during both the disarmed state
and the armed state, due to the output signals
from the immobiliser system.

(a) Check for DTCs and note any codes that are output.
(b) Delete the DTC.
(c) Recheck for DTCs. Try to prompt the DTC (SFI system
and engine immobiliser system) by simulating the
original activity that the DTC suggested.
(1) If the DTC does not reoccur, proceed to A.
(2) If the DTC (SFI system) reoccurs, proceed to B.
(3) If the DTC (engine immobiliser system) reoccurs,
proceed to C.
