1. Touch “DATA MONITOR” on “SELECT DIAG MODE ” screen.
2. Touch “ALL SIGNALS”, “MAIN SIGNALS” or “SELECTION FROM MENU” on the “SELECT MONITOR
ITEM” screen.
3. When “SELECTION FROM MENU” is selected, touch individual items to be monitored. In “ALL SIG-
NALS”, all items are monitored. In “MAIN SIGNALS”, predetermined items are monitored.
4. Touch “START”.
5. Touch “RECORD” while monitoring to record the status of the item being monitored. To stop recording,
touch “STOP”.
All Signals, Main Signals, Selection From Menu
NOTE:
Perform monitoring of IPDM E/R data with the ignition switch ON. When the ignition switch is at ACC, the dis-
play may not be correct.
ACTIVE TEST
Operation Procedure
1. Touch “ACTIVE TEST” on “SELECT DIAG MODE” screen.
2. Touch “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch item to be tested, and check operation.
4. Touch “OFF” while testing to stop the operation.
Diagnosis Mode Description
SELF−DIAG RESULTS Refer to PG-20, "
SELF-DIAG RESULTS" .
DATA MONITOR The input/output data of IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST IPDM E/R sends a drive signal to electronic components to check their operation.
ALL SIGNALS Monitors all items.
MAIN SIGNALS Monitor the predetermined item.
SELECTION FROM MENU Selects items and monitors them.

Front Wiper Does Not OperateNKS003WN
CAUTION:

During IPDM E/R fail-safe control, front wipers may not operate. Refer to PG-18, "CAN COMMUNI-
CATION LINE CONTROL" in “PG IPDM E/R” to make sure that it is not in fail-safe status.
1. ACTIVE TEST
With CONSULT-II
1. Select “IPDM E/R” by CONSULT-II, and select “ACTIVE TEST”
on “SELECT DIAG MODE” screen.
2. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch “LO” or “HI” screen.
Without CONSULT-II
Start up auto active test. Refer to PG-23, "
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-II
1. Select “BCM” on CONSULT-II, 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-II
Refer to LT- 2 3 9 , "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 3.
NG >> Check combination switch (wiper switch). Refer to LT-
239, "Combination Switch Inspection" .
3. CHECK CIRCUIT BETWEEN IPDM E/R AND BCM
Select “BCM” on CONSULT-II, and perform self-diagnosis for
“BCM”.
Displayed self
-diagnosis results
NO DTC>>Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
CAN COMM CIRCUIT>>Check CAN communication line of BCM.
Refer to BCS-13, "
CAN Communication Inspection
Using CONSULT-II (Self-Diagnosis)" .

ground while front wiper (HI, LO) is operating.
Without CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Install front wiper reverse relay.
3. Start up auto active test. Refer to PG-23, "
Auto Active Test" .
4. Check voltage between IPDM E/R harness connector and ground while front wiper (HI, LO) is operating.
OK or NG
OK >> Replace front wiper motor. Refer to WW-44, "Disassembly and Assembly of Front Wiper Drive
Assembly" .
NG >> Replace IPDM E/R. Refer to PG-31, "

Front Wiper Does Not Return to Stop Position (After Front Wiper Operate for 10
Seconds, They Stop for 20 Seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
NKS003WO
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”.
