Display Item List
CONSULT-II Functions (IPDM E/R)AKS007AE
CONSULT-II can display each diagnostic item using the following diagnostic test modes: work support, self-
diagnostic results, data monitor and active test through data reception and command transmission via the
IPDM E/R CAN communication line.
CONSULT-II OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, then turn the
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
Test item Indication on CONSULT-II display Description
Front wiper output FRONT WIPER With a certain operation (OFF, HI, LO, INT), the front wiper can be operated.
Rear wiper output RR WIPER Rear wiper can be operated by any ON-OFF operation.
Inspection Item, Diagnosis Mode Description
SELF-DIAGNOSTIC RESULTS The IPDM E/R performs self-diagnosis of CAN communication.
DATA MONITOR The input/output data of the IPDM E/R is displayed in real time.

1. CHECK FUNCTION OF COMBINATION METER
Confirm that speedometer operates normally.
Does the front wiper operate normally?
YES >> GO TO 2.
NO >> Combination meter vehicle speed system malfunction. GO TO DI-17, "
Vehicle Speed Signal
Inspection" .
2. CHECK CAN COMMUNICATION BETWEEN BCM AND COMBINATION METER
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.
GO TO BCS-14, "
CAN Communication Inspection Using
CONSULT-II (Self-Diagnosis)" .
Front Wiper Intermittent Operation Switch Position Cannot Be AdjustedAKS007YW
1. CHECK COMBINATION SWITCH INPUT SIGNAL
Select “BCM” on CONSULT-II. With “WIPER” data monitor, make
sure “INT VOLUME” changes in order from 1 to 7 according to oper-
ation of the intermittent switch dial position.
OK or NG
OK >> Replace BCM. Refer to LT- 11 3 , "Combination Switch
Inspection" .
NG >> Replace wiper switch.
Wipers Do Not Wipe When Front Washer OperatesAKS00575
1. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
Select “BCM” on CONSULT-II. With “WIPER” on “DATA MONITOR”,
make sure “FR WASHER SW” turns ON-OFF according to operation
of front washer switch.
OK or NG
OK >> Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .
NG >> Replace wiper switch.

After Front Wipers Operate for 10 Seconds, They Stop for 20 Seconds, and after
repeating the operations five times, they become inoperative
AKS007A2
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 CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (1)
With CONSULT-ll
Select “IPDM E/R” on CONSULT-II. With “DATA MONITOR”, confirm
that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper
operation.
Without CONSULT-ll
GO TO 2.
OK or NG
OK >> Replace IPDM E/R.
NG >> GO TO 2.
2. CHECK CIRCUIT BETWEEN IPDM E/R AND WIPER MOTOR (2)
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 E7 ter-
minal 32 (L) and front wiper motor harness connector E57 termi-
nal 5 (L).
4. Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L) and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
SKIA5301E
32 (L) - 5 (L) : Continuity should exist.
32 (L) - Ground : Continuity should not exist.

Component Parts and Harness Connector LocationAKS0057H
System DescriptionAKS0057I

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.

BCM (body control module) controls rear wiper ON and INT (intermittent) operation.
Power supplied all time

through 50 A fusible link (letter M, located in fusible link block)

to BCM (body control module) terminal 55

through 15 A fuse [No. 22, located in fuse block (J/B)]

to BCM (body control module) terminal 42.
When ignition switch ON or START position, power is supplied

through 15 A fuse [No.1, located in fuse block (J/B)]

to BCM (body control module) terminal 38,

through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]

to rear washer motor terminal 1.
Ground is supplied

to BCM (body control module) terminals 49 and 52

through grounds M35, M45 and M85

to combination switch (wiper switch) terminal 12

through grounds M35, M45 and M85.
REAR WIPER OPERATION
When wiper switch is in rear wiper ON position, BCM detects rear wiper ON signal by BCM wiper switch read-
ing function.
BCM operates rear wiper motor, power is supplied

through BCM terminal 70

to rear wiper motor 4.
Ground is supplied

to rear wiper motor terminal 2

through grounds B15 and B45.
With power and ground supplied, the rear wiper operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arms at low speed approximately every 7 seconds.
When wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch read-
ing function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ).
BCM operates rear wiper motor, power supplied

through BCM terminal 70

to rear wiper motor terminal 4.
Ground is supplied

to rear wiper motor terminal 2

through grounds B15 and B45.
With power and ground supplied, rear wiper operates at intermittent.
AUTO STOP OPERATION
With rear wiper switch turned OFF, rear wiper motor will continue to operate until wiper arm reaches rear wiper
stopper.
Then wiper motor turns the other way and wiper arm moves once until wiper arm reaches stopper.
WASHER OPERATION
When wiper switch is in rear wiper washer position, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ), and combina-
tion switch (wiper switch) ground is supplied

to rear washer motor terminal 2

through combination switch (wiper switch) terminal 13

to combination switch (wiper switch) terminal 12

through grounds M35, M45 and M85.
With ground supplied, rear washer motor is operated.
When BCM detects that rear washer motor has operated for. 0.4 seconds or linger, BCM operates rear wiper
motor low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then stops.
BCM WIPER SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" in BODY CONTROL SYSTEM.
