HOW TO REGISTER SECRET CODEM1428001000292
Each individual secret code is registered inside the
transmitter, and so it is necessary to resister these
codes with the EEPROM inside the receiver in the
following cases.
•When the transmitter or ETACS-ECU is replaced
•If more transmitters are to be used
•If it appears that a problem is occurring because
of faulty registration of a code.
A maximum of four different codes can be stored in
the EEPROM memory (four different transmitters can
be used). When the code for the first transmitter is
registered, the previously registered codes for all
transmitters are cleared. Therefore, if you are using
four transmitters or are adding more transmitters, the
codes for all transmitters must be registered at the
same time.

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
signal 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 wiper switch is turned to the
ON position with the ignition switch at the "ACC"
or "ON" position, the mist wiper high-speed
operation 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
working, the wipers work as the mist wiper.
However, the wipers return to the intermittent
mode again when the switch is changed back to
"INT" position.
•To prevent the windshield mist wiper from
operating when the windshield wiper switch is
turned OFF, the windshield mist wiper does not
work for 0.5 second after the windshield
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 switch at "ACC" or "ON"
position, the windshield washer 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 condition of the windshield
washer switch continues more than 0.2 second,
the wiper performs the same movement as
normal condition from the time when 0.2 second
has elapsed and then returns to the intermittent
motion.

The windshield wiper and washer are controlled by
the Smart Wiring System (SWS). For
troubleshooting, refer to GROUP 54B,
Troubleshooting P.54B-17 or GROUP 54C,
Troubleshooting P.54C-4.
NOTE: Even when the ETACS-ECU has failed, the
windshield wiper can work at low speed as fail-safe
mode. (Normally, the windshield wiper operates
when the ignition switch is at the "ACC" position. But,
if it enters the fail-safe mode, the wiper can operate
only when the ignition switch is at the "ON" position.)

WINDSHIELD INTERMITTENT WIPER
INSPECTION
1. If the windshield intermittent wiper interval
adjusting knob is operated, the wiper interval
should change.
2. Holding the windshield intermittent wiper interval
adjusting knob, input the simulated vehicle speed
with MUT-II MB991502 and check that the wiper
interval changes as the vehicle speed changes.
3. If not, carry out the troubleshooting (Refer to
GROUP 54B, Troubleshooting P.54B-17 or

REAR WIPER AND WASHER
GENERAL INFORMATIONM1511000100525
REAR WIPER AND WASHER OPERATION
Rear Wiper Operation
•If the rear wiper and washer switch is turned to
"INT" position with the ignition switch at "ACC" or
"ON" position, the ETACS-ECU turns ON the rear
wiper drive signal for three seconds
(approximately two cycles), then 7.4 seconds
later the intermittent motion operates every eight
seconds. If the selector lever is moved to the "R"
position when the rear wiper and washer switch is
turned to the "INT" position and the ignition
switch is at the "ACC" or "ON" position, the inhibitor switch "R" turns ON. One second later,
the ETACS-ECU turns ON the rear wiper drive
signal for three seconds (approximately two
cycles). Then, 7.4 seconds later, the intermittent
motion of eight seconds' cycle is restored.
Rear Washer Operation
•If the rear wiper and washer switch is turned to
the ON (washer) position with the ignition switch
at the "ACC" or "ON" position, the rear washer
ON signal is sent to the ETACS-ECU, causing the
rear wiper signal to turn on after 0.3 second. After
the rear washer switch signal turns off, the rear
wiper signal turns off in three seconds. If the rear
washer switch is turned to the ON position while
the rear wiper is in intermittent mode, the rear
washer works for that period when the washer
switch remains on. Then the rear wipers return to
the intermittent mode.
