BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.

OUTLINE
The front wiper is controlled by each function of BCM and IPDM E/R.
Control by BCM
• Combination switch reading function
 Front wiper control function
Control by IPDM E/R
 Front wiper control function
 Relay control function
FRONT WIPER BASIC OPERATION
 BCM detects the combination switch condition by the combination switch reading function.
 BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each
operating condition of the front wiper.
 IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper high relay according to the front
wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.
FRONT WIPER LO OPERATION
 BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
front wiper LO operating condition.
Front wiper LO operating condition
- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
 IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
FRONT WIPER HI OPERATION
 BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the
front wiper HI operating condition.
Front wiper HI operating condition
- Ignition switch ON
- Front wiper switch HI
 IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper
request signal (HI).
FRONT WIPER INT OPERATION (LINKED WITH VEHICLE SPEED)
JSLIA0135GB

WW-6
< FUNCTION DIAGNOSIS >
FRONT WIPER AND WASHER SYSTEM
 BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication according to the
front wiper INT operation condition and the intermittent operation delay interval judged value.
Front wiper INT operating condition- Ignition switch ON
- Front wiper switch INT
Intermittent operation delay interval judgment- BCM calculates the intermittent operation delay interval from the following
 Vehicle speed signal (received from the combination meter with CAN communication)
 Wiper intermittent dial position
 IPDM E/R turns the integrated front wiper relay ON so that the front wiper is operated only once according to
the front wiper request signal (INT).
 BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop
position signal received from IPDM E/R with CAN communication.
 BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval after
the front wiper motor is stopped.
FRONT WIPER AUTO STOP OPERATION
 BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
 IPDM E/R detects the front wiper stop position signal from the front wiper motor and detects the front wiper
motor position (stop position/except stop position).

 When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper
motor returns to the stop position.
NOTE:
 BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF.
 IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF.
FRONT WIPER OPERATION LINKED WITH WASHER
 BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the
washer linked operating condition of the front wiper.
 BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 3 times
when the front washer switch OFF is detected.
Washer linked operating condition of front wiper
- Ignition switch ON
- Front washer switch ON (0.4 second or more)
 IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
 The washer pump is grounded through the combination switch with the front washer switch ON.
FRONT WIPER FAIL−SAFE OPERATION
IPDM E/R performs the fail-safe function when the front wiper auto stop circuit is malfunctioning. Refer to
PCS-31, "
Fail-safe".

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
