 to BCM terminals 49 and 52
 through grounds M35, M45 and M85,
 to IPDM E/R terminals 38 and 60
 through grounds E21, E50 and E51,
 to combination switch terminal 12
 through grounds M35, M45 and M85.
LOW SPEED WIPER OPERATION
When wiper switch is in LOW position, BCM detects low speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (LO) through CAN communication
 from BCM terminals 39 and 40
 to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay located in IPDM E/R,
power is supplied
 through front wiper relay
 through front wiper high relay
 through IPDM E/R terminal 21
 to front wiper motor terminal 1.
Ground is supplied
 to front wiper motor terminal 2
 through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When wiper switch is in HI position, BCM detects high speed wiper ON signal by BCM wiper switch reading
function.
BCM sends front wiper request signal (HI) through CAN communication
 from BCM terminals 39 and 40
 to IPDM E/R terminals 48 and 49.
When IPDM E/R receives front wiper r equest signal (HI), it turns ON front wiper relay (located in IPDM E/R),
power is supplied
 through front wiper relay
 through front wiper high relay
 through IPDM E/R terminal 31
 to front wiper motor terminal 4.
Ground is supplied
 to front wiper motor terminal 2
 through grounds E21, E50 and E51.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation delay interval is det ermined from a combination of 3 switches (intermittent
operation dial position 1, 2, and 3) and vehicle speed signal.
Speed dependent wiper controlled mode can be changed by the function setting of CONSULT-III or display.
During each intermittent operation delay interval, BCM sends front wiper request signal to IPDM E/R.

INFOID:0000000001328562
CAUTION:
 When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front wip-
ers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this symp-
tom.
 This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
