TROUBLESHOOTING QUICK-REFERENCE TABLE
For information concerning the locations of electrical components, refer to GENERAL-Theft-alarm System
Circuit.
1.ARMING / DISARMING RELATIONSHIP
Trouble symptomThe system is not armed (The
SECURITY light doesn’t illumi-
nate, and the alarm doesn’t func-
tion.)
(The central door locking system
functions normally.
If the central locking system doesnot function normally, refer to
GROUP 42.)
The arming procedures are fol-
lowed, but the SECURITY light
does not illuminate.(There is an alarm, however,
when an alarm test is conductedafter about 20 seconds have
passed.)
The alarm sounds in error when,
while the system is armed, a door
or the liftgate is unlocked by us-
ing the key.

ECU: Electronic Control Unit
NOTEIf the
lifigate unlock switch or door key cylinder unlock switch is operated roughly, or if these switches have
been installed incorrectly or switches themselves are defective the ECU may not accept the warning or alarmcancelling signal. In such case, the alarm operation will take place when the door is opened using a key.
[When the door key cylinder switch has been shorted, however, if the ignition switch is turned ON, the ECU
judges the detection-switch as faulty and thereafter, it will prevent setting of (warning) alarm until the shorting
is corrected.]
If the
liftgate is opened using a key and is left opened when the door key cylinder switch system has a trouble
(wiring harness damage, open circuit, etc.), the ECU judges it as the
liftgate holding mode and does not producealarm even when the door is opened.

5. DOOR LOCK ACTUATOR SWITCH INPUT CIRCUIT
Description of operation
When a door is locked by the lock knob or the key, the door
lock actuator switch is switched OFF, and HIGH-level signals
are sent to the ECU. These signals activate the timer circuit
of the R ECU, thereby causing the activation circuit to function,thus
R activating the door lock actuator of all doors.
