System Description
FRONT WIPER CONTROL (BASIC)
- BCM detects the combination switch position by the combination switch
reading function.
- BCM transmits the front wiper request signal to the IPDM E/R using CAN
communication.
- IPDM E/R controls the integrated front wiper relay and front wiper high
relay based on the status of the
front wiper request signal.
- IPDM E/R provides power to operate the front wiper motor.
LOW SPEED OPERATION
- Ignition switch ON.
- Front wiper switch in LO or MIST position.
- BCM reads the combination switch position and transmits the front wiper
request signal (LO) to IPDM E/R
using CAN communication.
- IPDM E/R turns ON the front wiper relay.
HIGH SPEED OPERATION
- Ignition switch ON.
- Front wiper switch in HI.
- BCM reads the combination switch position and transmits the front wiper
request signal (HI) to IPDM E/R
using CAN communication
- IPDM E/R turns ON the front wiper relay and the front wiper high relay.
INTERMITTENT OPERATION
- Ignition switch ON.
- Front wiper switch INT.
- BCM reads the combination switch position. BCM calculates the delay
interval based on the table below
and then transmits the front wiper request signal (INT) to IPDM E/R using
CAN communication.
- IPDM E/R turns ON the front wiper relay only once.
- BCM detects stop position of the front wiper motor based on the front
wiper stop position signal received
from the IPDM E/R.
- BCM transmits the front wiper request signal (INT) again after the delay
interval.
AUTO STOP OPERATION
- Front wiper switch is turned OFF.
- BCM monitors wiper switch position by combination switch reading
position function.
- BCM stops transmitting the front wiper request signal to the IPDM E/R.
- IPDM E/R detects the front wiper auto stop signal from the position of
the front wiper motor (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
- IPDM E/R turns the front wiper relay OFF when the front wiper motor has
reached the stop position.
MIST OPERATION
- Ignition switch ON.
- Front washer switch in OFF position.
- Front wiper switch in MIST position.
- BCM reads the combination switch position and transmits the front wiper
request signal (LO) to IPDM E/R
using CAN communication.
- IPDM E/R turns ON the front wiper relay.
- The front wiper operates once after the front washer operation.
WIPER/WASHER OPERATION
- Ignition switch ON.
- Front washer switch ON.
- The front washer switch provides ground for the front washer motor.
- BCM reads the combination switch position and transmits the front wiper
request signal (LO) to IPDM E/R
using CAN communication.
- BCM transmits the front wiper request signal (LO) to IPDM E/R using CAN
communication.
- IPDM E/R turns ON the front wiper relay.
- The front wiper operates.
NOTE:
BCM transmits the front wiper request signal (LO) so that the front wiper
operates approximately 3 times after
front washer switch OFF is detected.
Fail-Safe
FAIL−SAFE OPERATION
IPDM E/R performs the fail-safe function when the front wiper auto stop
circuit is malfunctioning. Refer to
PCS-19, "Fail-safe" (with Intelligent Key system) or PCS-47, "Fail-Safe"
(without Intelligent Key system).
