OUTLINE
Power is supplied at all times
to ignition relay, located in IPDM E/R, from battery directly,
through 50 A fusible link (letter F, located in fuse and fusible link block)
to BCM terminal 55,
through 10 A fuse [No. 21, located in fuse block (J/B)]
to BCM terminal 42,
through 30 A fuse (No. 73, located in IPDM E/R)
to front wiper low relay, located in IPDM E/R
to front wiper reverse relay terminal 5,
through 15 A fuse (No. 78, located in IPDM E/R)
to CPU (central processing unit) located in IPDM E/R,
through 15 A fuse (No. 71, located in IPDM E/R)
to CPU located in IPDM E/R.
With the ignition switch in the ON or START position, power is supplied
to ignition relay, located in IPDM E/R,
through 15 A fuse [No. 1, located in fuse block (J/B)]
to BCM terminal 38,
through 10 A fuse [No. 12, located in fuse block (J/B)]
to front wiper reverse relay terminal 1,
through 10 A fuse (No. 84, located in IPDM E/R)
to combination switch terminal 11
to front wiper motor terminal 4.
Ground is supplied
to BCM terminal 52
through grounds M16 and M70,
to IPDM E/R terminals 38 and 51
through grounds E22 and E43,
to combination switch terminal 12
through grounds M16 and M70.
LOW SPEED WIPER OPERATION
When wiper switch is in the LO position, BCM detects low speed wiper ON signal by BCM wiper switch read-
ing function.
BCM sends front wiper request signal (LO) with CAN communication line
from BCM terminals 39 and 40
to IPDM E/R terminals 49 and 50.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper low relay, located in IPDM
E/R, power is supplied
through IPDM E/R terminal 23 and front wiper high relay and front wiper low relay
to front wiper motor terminal 3.
Ground is supplied
to front wiper motor terminal 1
through front wiper reverse relay terminals 3 and 4
through grounds E22 and E43.
With power and ground supplied, the front wiper motor operates at low speed.
