2. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch “LO” or “HI” screen.
Without CONSULT-lIl
Start up auto active test. Refer to PG-19, "
Auto Active Test" .
Does front wiper operate normally?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-llI
1. Select “BCM” on CONSULT-III, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen. Make sure that “FR WIPER INT”, “FR
WIPER LOW”, and “FR WIPER HI” turn ON-OFF according to wiper switch operation.
Without CONSULT-lIl
Refer to LT-63, "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 3.
NG >> Check combination switch (wiper switch). Refer to LT-63, "
Combination Switch Inspection" .
3.CHECK CIRCUIT BETWEEN IPDM E/R AND BCM
Select “BCM” on CONSULT-III, and perform self-diagnosis for “BCM”.

INFOID:0000000001704547
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”.
1.CHECK FRONT WIPER STOP SIGNAL

Component Parts and Harness Connector LocationINFOID:0000000001704565
System DescriptionINFOID:0000000001704566
• The wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by the BCM (body control module) when switch is turned ON.
• The BCM controls rear wiper ON and INT (intermittent) operation.
Power is supplied at all times
• through 40A fusible link (letter g , located in fuse and fusible link box)
• to BCM terminal 70.
With the ignition switch in ON or START position, power is supplied
• through 15A fuse [No. 4, located in the fuse block (J/B)]
• to combination switch terminal 2
• through 10A fuse [No. 6, located in the fuse block (J/B)]
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67, and
• to combination switch terminal 12
• through grounds M57 and M61.
REAR WIPER OPERATION
When the ignition switch is in the ON or START position, and the rear wiper switch is in the ON position, the
BCM detects a rear wiper ON request through the combination switch (wiper switch) reading function and con-
trols the rear wiper motor as follows.
Power is supplied
• through BCM terminal 55
• to rear wiper motor terminal 1.
Ground is supplied
• to rear wiper motor terminal 3
