OPERATIONl
If the defogger switch is turned to “ON” when the generator is generating electricity (L terminal exceeds
10 V.) with the ignition switch at the “ON” position, the timer circuit in the ETACS unit will be operated
to keep the transistor “on” for 11 minutes to close the contact point of the defogger relay. When the
defogger relay is “on”,the defogger and mirror heater will be activated. Moreover, the indicator lightof the defogger switch is lit to inform that the defogger and mirror heater are activated.
lWhen 11 minutes have passed, the defogger and mirror heater will stop activating even if the defoggerswitch is at “ON”. When the defogger and mirror heater are activated (the timer is activated), they
will also stop activating even if the defogger switch is set at “ON” again or if the generator stops
generating electricity (the terminal is 3.5 V or less.)
NOTE
The light automatic shut-off system is valid for the illumination light of the defogger switch. (Refer to
P.54-37.)
TROUBLESHOOTING HINTS
NOTE
For the troubleshooting hints of the automatic light shut-OFF system, refer to P.54-38.

INPUT SIGNAL
<Up to 1993 models>
When using the scan tool
(MUT) or voltmeter
Using the scan tool or voltmeter, check whether or not the
input signals from each switch are being input to the ETACS
unit.
(1) Connect the scan tool to the data link connector located
at the right side of the junction block or connect the voltme-
ter between the ETACS terminal and the ground terminal.
(2) Check if the buzzer of the scan tool sounds or the needle
of the voltmeter moves when each switch is operated.
If the buzzer sounds or the needle moves, the input signalsare being input to the ETACS unit, so that switch can
be considered to be functioning normally. If not, the switch
or switch input circuit is faulty. Check the switch and the
switch input circuit.
<All models>
When using the scan tool (MUT-II)
(1) Connect the scan tool to the data link connector. When
connecting the scan tool to a vehicle up to 1993 models,
use the adapter harness supplied together.
Caution
Turn off the ignition switch beforehand whenever thescan tool is connected or disconnected.
(2) If the scan tool makes a peep sound when each switchis operated (turned ON/OFF), the input signal to ECU
is normally sent from the switch circuit system.<From
1994 models>
When using the voltmeter
(1)Connect a voltmeter to the ETACS terminal and the ground
terminal of the data link connector using the special tool.
(2) If the voltmeter pointer deflects once when each switchis operated (turned ON/OFF), the input signal to
.ECU
is normally sent from the switch circuit system.

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.
