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 this condition, refer to WW-5, "
LOW SPEED WIPER
OPERATION" .
If switch is held in mist position, 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 were 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
Description

BCM reads combination switch (wiper) status, and controls related systems such as headlamps and wip-
ers, according to the results.

BCM reads information of a maximum of 20 switches by combining five output terminals (OUTPUT 1 - 5)
and five input terminals (INPUT 1 - 5).
Operation Description

BCM activates transistors of output terminals (OUTPUT 1 - 5) periodically, and allows current to flow in
turn.

If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1 - 5) and input terminals
(INPUT 1 - 5) becomes active.

At this time, transistors of output terminals (OUTPUT 1 - 5) are activated to allow current to flow. When
voltage of input terminals (INPUT 1 - 5) corresponding to that switch changes, interface in BCM detects
voltage change, and BCM determines that switch is ON.

Front Wiper Does Not OperateNKS0052B
CAUTION:
During IPDM E/R fail-safe control, front wipers may not operate. Refer to PG-16, "
CAN COMMUNICA-
TION LINE CONTROL" in “PG IPDM E/R” to make sure that it is not in fail-safe status.
1. ACTIVE TEST
CONSULT-III ACTIVE TEST
1. Select "FRONT WIPER" of IPDM E/R active test item.
2. With operating the test item, check that front wiper LO and HI operation.
IPDM E/R AUTO ACTIVE TEST
1. Start up auto active test. Refer to PG-20, "
Auto Active Test" .
2. With operating the test item, check that front wiper LO and HI operation.
Does front wiper operate normally?
YES >> GO TO 5.
NO >> GO TO 2.
2. CHECK FRONT WIPER CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
Ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK GROUND CIRCUIT
Check continuity between front wiper motor harness connector and
ground.
OK or NG
OK >> GO TO 4.
NG >> Repair harness or connector.

After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After
Repeating the Operations Five Times, They Become Inoperative
NKS0052J
CAUTION:

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
1. CHECK WIPER MOTOR SIGNAL
CONSULT-III DATA MONITOR
1. Select "WIP AUTO STOP" of BCM data monitor item.
2. make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper operation.
GO TO 2
OK or NG
OK >> Replace IPDM E/R. Refer to PG-26, "Removal and Installation of IPDM E/R" .
NG >> GO TO 2.
2. CHECK WIPER AUTO STOP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
