THE PRINTED-HEATER LINES CHECK
(1) Run engine at 2,000 rpm. Check heater element with bat-tery at full.
(2) Turn ON rear window defogger switch. Measure heater
element voltage with circuit tester at rear window glass
center A.
Condition good if indicating about 6 V.
(3) If 12 V is indicated at A, there is a break in the negative
terminals from A.
Move test bar slowly to negative terminal to detect where
voltage changes suddenly (0 V).(4) If 0 V is indicated at A, there is a break in the positive
terminals from A. Detect where the voltage changes sud-
denly (12 V) with the same method described.
THE PRINTED-HEATER LINES REPAIR
REQUIRED MATERIALSl Thinner
l Tapel Lead-free gasoline
l Fine brush
l Conductive paint
(1) Clean disconnected area with lead-free gasoline. Tape
along both sides of heater element.
(2) Mix conductive paint thoroughly. Thin the required amount
of paint in a separate container with a small amount of
thinner and paint break three times at 15 minute intervals.(3) Remove tape and leave for a while before use (circuit
complete).
(4) When completely dry (after 24 hours) finish exterior with
a knife.
Caution
Clean glass with a soft cloth (dry or damp) along defog-
ger heater element.REAR WINDOW DEFOGGER SWITCH
(1)Remove rear window defogger switch from the meter bezel.(Refer to
P.54-109.)
(2) Operate the switch and check the continuity between the
terminals.

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.
