12. REMOVAL OF TIMING BELT(1) Align the timing marks.
(2) Make a mark on the back of the timing belt indicating
the direction of rotation so it may be reassembled in the
same direction if it is to be reused.
(3) Loosen the center bolt on the tensioner pulley to
remove the timing belt.
Caution
Water or oil on the belt shorten its life drastically, sothe removed timing belt, sprocket, and tensioner
must be free from oil and water. These parts should
not be washed. Replace parts if seriously contamin-
ated.
If there is oil or water on each part check. the front
case oil seals, camshaft oil seal and water pump for
leaks.SERVICE POINTS OF INSTALLATION

13. INSTALLATION OF AUTO TENSIONER
(‘I) If the auto tensioner rod is in its fully extended position,
reset it as follows.@ Keep the auto tensioner level
and: in that position,
clamp it in the vise with soft jaws.@ Push in the rod little by little with the vise until the
set hole @ in the rod is aligned with that @ in the
cylinder.
CautionPush in the rod slowly to prevent the push rod
from being damaged.@ Insert a wire [I
.4 mm (.055 in.) in diameter] into the
set
ho&.@ Unclamp the auto tensioner from the vise.
(2) Install the auto tensioner.
CautionLeave the wire installed in the auto tensioner.

0When, with the ignition switch at the ON
position, a power-window (main or sub) switch
(“UP” side or “DOWN” side) is pressed, current
flows through sub-fusible link No. 8 and to the
power-window motor, thus causing the door
window glass to close or open.
When the “DOWN” side of the power-window
main switch at the driver’s side is pressed all the
way, it is locked at the pressed-in position, and
the power-window motor operates until the
door glass is fully opened.
When the power-window lock switch is set to
the “LOCK (ON)” position, the power-window
motor will not operate if any switch (main or sub)
other than at the driver’s side is operated.
A circuit breaker is provided in the power-window motor in order to prevent damage to the
motor as a result of excessive current.
For reference: Circuit breaker characteristics
Motor operation is restricted at high
temperatures
:
[20 - 25°C (68 - 77”F)].Current flow is cut by an initial current
occurs within 60 seconds if then left as
Iflow time of four to 40 seconds; resetis.The timer function of the ETACS permits the
power-window relay to remain ON for 30
seconds after the ignition switch is switched
OFF.If, during that period of time, the front door is
opened, the power-window relay is switched
OFF, and the power windows can no longer be
operated.
TROUBLESHOOTING HINTS1. All door windows cannot be opened or closed.
l Check sub-fusible link No. 8.
l Check the power-window relay.
l Check the power-window main switch.
2.One of the door windows cannot be opened or
closed.
(1) Neither of the power-window switches
(main or sub) operates.
l Check the power-window main switch.
lCheck the power-window motor for the
power window that does not operate.
(2) Either the power-window main switch or
sub switch does not operate.
lCheck the power-window switch for the
power window that does not operate.
3. The one-touch down switch function only does
not operate.
lReplace the power-window main switch.
4.The power window operation by ETACS control
after the ignition switch is switched OFF does
not function.
l Refer to
P.42-43.

6. REMOVAL OF WIPER MOTOR
(1) Remove the wiper motor mounting bolts.
(2) Using a plain screwdriver, detach the crank arm of the
wiper motor from the linkage to remove the wiper
motor.
Caution
Do not remove the crank arm from the wiper motor
except when necessary, as the auto stop angle has
been preset. When the crank arm is to be removed,
make a mark on both of them before removal.
INSPECTION
INSPECTION OF WIPER MOTOR
Inspect the wiper motor mounted on the vehicle with its
connector disconnected.
Inspection of Wiper Motor Operation at LOW and HIGH
Speeds
Connect the battery to the wiper motor as shown, and check its
operation at LOW and HIGH speeds.
Inspection of Wiper Motor STOP Position
(1) Operate the wiper motor at LOW speed and intermediately
disconnect the battery to let the wiper motor stop.
(2) Connect the terminals as well as the battery, as shown, and
check that the wiper motor stops at the automatically-
stopped position following LOW-speed operation.
INSPECTION OF COLUMN SWITCH
(1) Remove the knee protector.
(Refer to GROUP 52A
- Instrument Panel.)
(2) Remove the column cover.
(3) Remove the column switch right coupling connector
(11terminals).
Inspection of Wiper and Washer Switch
Operate the switch to check for continuity between the
terminals.
