1.

GET INFORMATION FOR SYMPTOM

1.

Get detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurs).

2.

Check operation condition of the function that is malfunctioning.

>> GO TO 2.

2.

CHECK DTC

1.

Check DTC.

2.

Perform the following procedure if DTC is detected.

-

Record DTC and freeze frame data (Print them out using CONSULT.)

-

Erase DTC.

-

Study the relationship between the cause detected by DTC and the symptom described by the customer.

3.

Check related service bulletins for information.

Are any symptoms described and any DTC detected?

Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.

3.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer.
Also study the normal operation and fail-safe related to the symptom.
Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 5.

4.

CONFIRM THE SYMPTOM

Try to confirm the symptom described by the customer.
Verify relation between the symptom and the condition when the symptom is detected.

>> GO TO 6.

5.

PERFORM DTC CONFIRMATION PROCEDURE

Perform DTC CONFIRMATION PROCEDURE for the detected DTC, and then check that DTC is detected
again. At this time, always connect CONSULT to the vehicle, and check self diagnostic results in real time.
If two or more DTCs are detected, refer to 

BCS-53, "DTC Inspection Priority Chart"

 (BCM) or 

PCS-23,

"DTC Index"

 (IPDM E/R), and determine trouble diagnosis order.

NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service

Manual. This simplified check procedure is an effective alternative though DTC cannot be detected during
this check.
If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIR-
MATION PROCEDURE.

Is DTC detected?

YES

>> GO TO 7.

NO

>> Check according to 

GI-40, "Intermittent Incident"

.

6.

DETECT MALFUNCTIONING SYSTEM BY SYMPTOM DIAGNOSIS

Detect malfunctioning system according to SYMPTOM DIAGNOSIS based on the confirmed symptom in step
4, and determine the trouble diagnosis order based on possible causes and symptom.

Is the symptom described?

YES

>> GO TO 7.

NO

>> Monitor input data from related sensors or check voltage of related module terminals using CON-

SULT.

7.

DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE

Revision: 2013 February

2012 Murano CrossCabriolet

WW-22

< BASIC INSPECTION >

DIAGNOSIS AND REPAIR WORK FLOW

Inspect according to Diagnosis Procedure of the system.

Is malfunctioning part detected?

YES

>> GO TO 8.

NO

>> Check according to 

GI-40, "Intermittent Incident"

.

8.

REPAIR OR REPLACE THE MALFUNCTIONING PART

1.

Repair or replace the malfunctioning part.

2.

Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.

3.

Check DTC. If DTC is detected, erase it.

>> GO TO 9.

9.

FINAL CHECK

When DTC is detected in step 2, perform DTC CONFIRMATION PROCEDURE again, and then check that the
malfunction is repaired securely.
When symptom is described by the customer, refer to confirmed symptom in step 3 or 4, and check that the
symptom is not detected.

Is DTC detected and does symptom remain?

YES-1 >> DTC is detected: GO TO 7.
YES-2 >> Symptom remains: GO TO 4.
NO

>> Before returning the vehicle to the customer, always erase DTC.

1.

CHECK FRONT WIPER LO OPERATION

CONSULT ACTIVE TEST

1.

Select “FRONT WIPER” of IPDM E/R active test item.

2.

With operating the test item, check front wiper operation.

Is front wiper (LO) operation normally?

YES

>> Front wiper motor LO circuit is normal.

NO

>> Refer to 

WW-23, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000007566623

1.

CHECK FRONT WIPER MOTOR (LO) OUTPUT VOLTAGE

1.

Turn ignition switch OFF, and wait for 20 seconds or more.

2.

Disconnect front wiper motor connector.

3.

Turn ignition switch ON, and wait for 10 seconds.

4.

Check voltage between front wiper motor harness connector and ground.

*: According to front wiper protection function, IPDM E/R supplies voltage for 10 seconds (battery voltage) and
then stops for 20 seconds (0 V). This operations repeats 5 times, and then IPDM E/R stops voltage supply. To
perform the check again, turn ignition switch OFF, wait for 20 seconds or more, and then perform the check.
Is the inspection result normal?

YES

>> Replace front wiper motor.

NO

>> GO TO 2.

2.

CHECK FRONT WIPER MOTOR (LO) CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Check continuity between IPDM E/R harness connector and front wiper motor harness connector.

4.

Check continuity between IPDM E/R harness connector and ground.

Is the inspection result normal?

YES

>> Replace IPDM E/R.

NO

>> Repair or replace harness.
