The relays in the ICM box cannot be replaced respectively; so if the any of the components on
the PCB are defective, they should be replaced as an assembly.

(3) Turn signal lamp (Hazard warning lamp operation)
The B+ power supplied through the No. F66 interior fuse on the right-hand of the engine compartment is
on standby on the No. 30 and 86 hazard warning lamp relay terminals via the ICM No. 18 terminal.
The STICS activates and/or controls the hazard warning lamp relay using the No. A26 terminal
depending on the operating conditions. The activated relay supplies the No. 87 and 87a terminals with
the power, which is on standby on the No. 30 hazard warning lamp relay terminal.
The supplied power flows to the corresponding circuit via the No. 7 and 16 ICM terminals.

▶Auto Washer and Wiper Switch (AFW)When the auto washer switch is turned on with the ignition switch "ON" and the INT switch
"OFF", the washer motor output gets ON for 1 second. If the system recog\
nizes the output signal,
the wiper relay output gets ON during 4 cycles and the washer motor output gets ON for 1
second. Then, the wiper relay output gets OFF after 3 cycles.

Rain sensing unit
(AUTO light integrated type)
▶INT Switch Auto Position Remi nder (Power-Up Reminder Wiper)
When turning off and on the auto INT switch, the system drives the wiper motor through LOW
relay regardless of communication with rain sensor.
When turning the INT-AUTO switch from the "OFF" to "ON" position with the ignition switch in the
"ON" mode, the LOW relay operates to drive the wiper motor for 1 cycle, regar\
dless of the rain
sensor communication.
After that, when turning the INT-AUTO switch fr om the "OFF" to "ON" position, the LOW relay
operates to drive the wiper motor for 1 cycle only if data from the rain\
sensor indicates rain drops.

Multifunction wiper switch:
AUTO and sensitivity control
A sensor that emits infrared rays through LED and
then detects the amount of rain drops by receiving
reflected rays against sensing section (rain senso
r
mounting section on the windshield) with
photodiode (auto light sensor integrated type) AUTO
: Wiper operates automatically by rain sensor
FAST↔SLOW : Auto delay/Auto speed control. A
position that can control sensitivity against rains on
the windshield and transmits wiping demand signal
accordingly

▶Sensitivity ControlThe wiper LOW relay is turned on and the wiper motor runs one cycle when the volume sensitivity
is increased (ex: sensitivity 0 ⇒ 1) while the ignition switch and the INT switch is in the "ON"
position, and the wiper motor is in "Parked" position). However, the wiper motor can be operated
only when the rain sensor detects the "Rain Detected" signal.
If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs
only one cycle.

▶Tail Lamp Left On WarningThe chime buzzer sounds with the interval of 0.8 second when opening the\
driver's door while the
tail lamp is turned on and the ignition key is removed.
The c/buzzer output stops when turning off the tail lamp and closing the\
driver's door.
The system outputs "UNLOCK" signal for 5 seconds when the driver's and p\
assenger's door lock
switch is locked (while the tail lamp is turned on and the driver's doo\
r is open).
This function does not work when the IGN1 switch is in "ON" position.
