System Description

FRONT WIPER CONTROL (BASIC)

LOW SPEED OPERATION

  1. Ignition switch ON.
  2. Front wiper switch in LO or MIST position.
  3. BCM reads the combination switch position and transmits the front wiper request signal (LO) to IPDM E/R using CAN communication.
  4. IPDM E/R turns ON the front wiper relay.

HIGH SPEED OPERATION

  1. Ignition switch ON.
  2. Front wiper switch in HI.
  3. BCM reads the combination switch position and transmits the front wiper request signal (HI) to IPDM E/R using CAN communication
  4. IPDM E/R turns ON the front wiper relay and the front wiper high relay.

INTERMITTENT OPERATION

  1. Ignition switch ON.
  2. Front wiper switch INT.
  3. 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.
  4. IPDM E/R turns ON the front wiper relay only once.
  5. BCM detects stop position of the front wiper motor based on the front wiper stop position signal received from the IPDM E/R.
  6. BCM transmits the front wiper request signal (INT) again after the delay interval.


AUTO STOP OPERATION


AUTO STOP OPERATION

  1. Front wiper switch is turned OFF.
  2. BCM monitors wiper switch position by combination switch reading position function.
  3. BCM stops transmitting the front wiper request signal to the IPDM E/R.
  4. IPDM E/R detects the front wiper auto stop signal from the position of the front wiper motor (stop position/ except stop position).
  5. 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
  6. IPDM E/R turns the front wiper relay OFF when the front wiper motor has reached the stop position.

MIST OPERATION


MIST OPERATION

  1. Ignition switch ON.
  2. Front washer switch in OFF position.
  3. Front wiper switch in MIST position.
  4. BCM reads the combination switch position and transmits the front wiper request signal (LO) to IPDM E/R using CAN communication.
  5. IPDM E/R turns ON the front wiper relay.
  6. The front wiper operates once after the front washer operation.

WIPER/WASHER OPERATION

  1. Ignition switch ON.
  2. Front washer switch ON.
  3. The front washer switch provides ground for the front washer motor.
  4. BCM reads the combination switch position and transmits the front wiper request signal (LO) to IPDM E/R using CAN communication.
  5. BCM transmits the front wiper request signal (LO) to IPDM E/R using CAN communication.
  6. IPDM E/R turns ON the front wiper relay.
  7. 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).
