IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
This system is equipped with two ignition coils (A and
B) with built-in power transistors for the No. 1 and
No. 4 cylinders and the No. 2 and No. 3 cylinders
respectively.
Interruption of the primary current flowing in the pri-
mary side of ignition coil A generates a high voltage
in the secondary side of ignition coil A. The high volt
-
age thus generated is applied to the spark plugs of
No. 1 and No. 4 cylinders to generate sparks. At the
time that the sparks are generated at both spark
plugs, if one cylinder is at the compression stroke,
the other cylinder is at the exhaust stroke, so that
ignition of the compressed air/fuel mixture occurs
only for the cylinder which is at the compression
stroke.
In the same way, when the primary current flowing in
ignition coil B is interrupted, the high voltage thus
generated is applied to the spark plugs of No. 2 and
No. 3 cylinders.
The engine-ECU or engine-A/T-ECU
turns the two power transistors inside the ignition
coils alternately on and off. This causes the primary
currents in the ignition coils to be alternately inter
-
rupted and allowed to flow to fire the cylinders in the
order 1-3-4-2.
The engine-ECU or engine-A/T-ECU
determines which ignition coil should be controlled
by means of the signals from the camshaft position
sensor which is incorporated in the camshaft and
from the crank angle sensor which is incorporated in
the crankshaft. It also detects the crankshaft position
in order to provide ignition at the most appropriate
timing in response to the engine operation condi
-
tions. It also detects the crankshaft position in order
to provide ignition at the most appropriate timing in
response to the engine operation conditions.
When the engine is cold or operated at high alti-
tudes, the ignition timing is slightly advanced to pro-
vide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce out
-
put torque, thereby alleviating shifting shocks.

WINDSHIELD WIPER AND WASHER

WINDSHIELD WIPER AND WASHER
GENERAL INFORMATIONM1511000100514
WINDSHIELD WIPER AND WASHER
OPERATION
Windshield Low-speed (and High-speed)
Wiper Operation
•If the windshield low-speed wiper switch is turned
to the ON position with the ignition switch at the
"ACC" or "ON" position, the column switch sends
a low-speed wiper ON and high-speed wiper OFF
signals to the front-ECU. This turns the wiper sig
-
nal on and the wiper speed control relay off
(low-speed), causing the wipers to operate at
low-speed.
•If the windshield high-speed wiper switch is
turned to the ON position, the column switch
sends a low-speed wiper OFF and high-speed
wiper ON signals to the front-ECU. This turns
both the wiper signal and the wiper speed control
relay on (high-speed), causing the wipers to
operate at high-speed.
NOTE: The windshield wiper speed is switchable
with the built-in wiper speed control relay.
High-speed operations take place when the wiper
speed control relay is set to "ON" and low-speed
operations take place when the wiper speed control
relay is set to "OFF".
Windshield Intermittent Wiper Operation
The ETACS-ECU calculates the wiper operation
interval according to the voltage signal sent from the
column switch. Then the ETACS-ECU sends a signal
to the front-ECU. The front-ECU determines the
wiper operation interval and turns on the wiper relay
signal relay. This causes the wiper auto stop relay to
turn on. Then the wiper auto stop relay will turn off
after the wipers reach the park position. This causes
the wiper signal relay and then the wipers to turn off.
If the wiper signal relay remains off for the wiper
operation interval, the relay turns on again, causing
the wipers to operate in intermittent mode.
Windshield Mist Wiper Operation
•If the windshield mist wipe r switch is turned to the
ON position with the ignition switch at the "ACC"
or "ON" position, the mist wiper high-speed oper
-
ation signal is sent to the front-ECU. This signal
turns on the wiper speed control relay, causing
the wipers to work at high-speed while the mist
switch is on.
•While the windshield mist wiper switch remains
turned on when the intermittent mode is still work
-
ing, the wipers work as the mist wiper. However,
the wipers return to the intermittent mode again
when the switch is changed back to "INT" posi
-
tion.
•To prevent the windshield mist wiper from operat-
ing when the windshield wiper switch is turned
OFF, the windshield mist wiper does not work for
0.5 second after the windshi eld intermittent wiper
switch, the windshield low-speed wiper switch
and the windshield high-speed wiper switch are
turned OFF.
Windshield Washer Operation
•If the windshield washer switch is turned to ON
position with the ignition sw itch at "ACC" or "ON"
position, the windshield wa sher ON signal is sent
to the front-ECU. After 0.3 second, the windshield
wiper signal turns on. After the windshield washer
switch signal turns off, the windshield wiper signal
turns off in three seconds.
•If the windshield washer switch is turned on while
the windshield wiper is at intermittent mode,
when the windshield washer switch is turned OFF
within 0.2 second, the wiper works only once to
perform mist operation by the windshield washer
switch. When the ON condi tion of the windshield
washer switch continues more than 0.2 second,
the wiper performs the same movement as nor
-
mal condition from the time when 0.2 second has
elapsed and then returns to the intermittent
motion.
