FRONT WIPER AND WASHER SYSTEM
Component Parts and Har ness Connector Location INFOID:0000000004306904
System Description INFOID:0000000004306905
• Front wiper relays (front wiper relay, front wiper hi gh relay) are located in the IPDM E/R (intelligent power
distribution module engine room).
• Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM (body control module) when switch is turned ON.
• BCM controls front wiper LO, HI, and INT (intermittent) operation.
• IPDM E/R operates wiper motor accordi ng to CAN communication signals from BCM.
OUTLINE
Power is supplied at all times
• to ignition relay, located in IPDM E/R, from battery directly,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70,
• through 30A fuse (No. 39, located in IPDM E/R)
• to front wiper relay located in IPDM E/R
• through 15A fuse (No. 52, located in IPDM E/R), and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied
• through ignition relay (located in IPDM E/R)
• to front wiper relay (located in IPDM E/R), and 1. IPDM E/R E45, E46 and E48 2. BCM M18 and M20 (view with glove
box removed)3. Front wiper motor E1
(view with cowl
top cover removed)
4. Front and rear washer motor E2 (view with front bumper fascia re-
moved) 5. Combination switch (wiper switch)

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, fr ont 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-3, " 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 positi on, 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.)

Front Wiper Does Not Return to Stop Positi on (After Front Wiper Operate for 10 Sec-

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 PROT” item
shows “BLOCK”. OK >> Replace IPDM E/R. Refer to
