AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will cont inue to operate until wiper arms reach windshield base.
When the wiper arms are not located at base of wi ndshield with wiper switch OFF, ground is supplied
• from IPDM E/R terminal 33
• to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
When the wiper arms reach base of windshield, front wiper motor terminals 4 and 2 are connected, and
ground is supplied
• to IPDM E/R terminal 38
• through front wiper motor terminals 4 and 2, and
• through grounds E15 and E24.
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When the BCM receives auto-stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN com-
munication line.
IPDM E/R stops wiper motor. Wiper motor wi ll then stop wiper arms at the STOP position.
WASHER OPERATION
When the wiper switch is in front wiper washer positi on, BCM detect front wiper washer signal by BCM combi-
nation switch reading function. Refer to BCS-4, "
System Description" .
Combination switch power is supplied• through combination switch terminal 14
• to washer motor terminal 1.
Ground is supplied• to front washer motor terminal 2
• through combination switch terminal 11, and
• through combination switch terminal 12
• through grounds M57 and M61.
With ground supplied, front washer motor is operated.
When the BCM detects that front washer motor has operated for 0.4 seconds or longer, BCM operates front
wiper motor for low speed.
When the BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.
MIST OPERATION
When the wiper switch is turned to the mist position, wiper low speed operation cycles once and then stops.
For additional information about wiper operation under th is condition, refer to "LOW SPEED WIPER OPERA-
TION" .
If switch is held in mist posit ion, low speed operation continues.
FAIL-SAFE FUNCTION
If an abnormality occurs in CAN communications, IPDM E/ R holds the condition just before fail-safe status is
initiated until ignition switch is turned OFF. (If wipers we re operating in LO just before the initiation of fail-safe
status, they continue to operate in LO until ignition switch is turned OFF.)
COMBINATION SWITCH READING FUNCTION
