match-marks on the glass and liftgate and force the glass
lightly and evenly for complete fitting.
(5) Remove adhesive from around and on the glass and
body surfaces using a spatula and wipe the surfaces
clean.(6) After the work (installation of the glass), allow to stand
until the adhesive hardens.
Caution
If an infrared lamp or other means are used for
quicker hardening, keep the surface temperature
60°C (140°F) or lower.
(7) After about 30 minutes or more following bonding of
the liftgate glass to the tail gate, check for water leaks.
Caution
1. If the vehicle is to be moved, do so gently.
2. When checking for water leaks, do not squeeze
the hose end.TSB

INPUT CHECK
Using the multi-use tester or voltmeter, check whether or not
the input signals from each switch are being input to the
ETACS unit.
(I), Connect the multi-use tester to the diagnosis check
connector located at the right side of the junction block or
connect the voltmeter between the ETACS terminal and
the ground terminal.
(2) Check if the buzzer of the multi-use tester sounds or the
needle of the voltmeter moves when each switch noted
below is operated.
If the buzzer sounds or the needle moves, the input signals
are 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.

Description of operation
When the ignition switch is switched to the “ON” position, and also for a period of 30 seconds after the
ignition switch is switched to the “OFF” position, the transistor of the electronic control unit is switched ON,
and battery voltage is supplied from the battery (through fusible link No. 9) to the power window relay.
In addition, voltage is supplied (through fusible link No. 9) to power window switch and motor as a result of
the switch-ON of the power window relay.
NOTETurn the ignition switch from ON to OFF, and power will be supplied to the power window relay for 30
seconds. However, power supply will be stopped if the door is opened during this period.
