DIAGNOSIS AND REPAIR WORKFLOW
[WITH INTELLIGENT KEY SYSTEM]
1.GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2.
2.CHECK FOR DTC
1. Check DTC for BCM and Automatic back door.
2. Perform the following procedure if DTC is displayed.
- Record DTC and freeze frame data (Print them out with CONSULT-III.)
- 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.
Is any symptom described and any DTC detected?
Symptom is described, DTC is displayed>>GO TO 3.
Symptom is described, DTC is not displayed>>GO TO 4.
Symptom is not described, DTC is displayed>>GO TO 5.
3.CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM

Confirm the symptom described by the customer.
Connect CONSULT-III to the vehicle in “DATA MONITOR” mode and check real time diagnosis results.
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 displayed DTC, and then check that DTC is detected again.
At this time, always connect CONSULT-III to the vehicle, and check diagnostic results in real time.
If two or more DTCs are detected, refer to DLK-254, "
"DTC Inspection Priority Chart" (automatic back door control unit) and determine trouble diagnosis order.
NOTE:
Perform Component Function Check if DTC Confirmation Procedure is not included in 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 Confirmation
Procedure.
Is DTC detected?
YES >> GO TO 7.
NO >> Refer to GI-40, "
Intermittent Incident".
DTC Inspection Priority Chart" (BCM) or DLK-268,
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.
>> GO TO 7.
7.DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE

DIAGNOSIS AND REPAIR WORKFLOW
Revision: 2008 October 2009 Murano
< BASIC INSPECTION >
Is malfunctioning part detected?
YES >> GO TO 8.
NO >> Check voltage of related BCM terminals using CONSULT-III.
[WITH INTELLIGENT KEY SYSTEM]
8.REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replacement.
3. Check DTC. If DTC is displayed, erase it.
>> GO TO 9.
9.FINAL CHECK
When DTC was detected in step 2, perform DTC Confirmation Procedure or Component Function Check
again, and then check that the malfunction has been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that
the symptom is not detected.
Does the symptom reappear?
YES (DTC is detected)>>GO TO 7.
YES (Symptom remains)>>GO TO 6.
NO >> INSPECTION END

DOOR LOCK FUNCTION
• The door lock and unlock switch (driver side) is build into power window main switch.
• The door lock and unlock switch (passenger side) is on door trim.
• Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors are
locked.
• Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors and
are unlocked.
Door Key Cylinder
• With the door key inserted in the door key cylinder on driver side, turning it to “LOCK”, will lock door lock
actuator of all doors.
• With the door key inserted in the door key cylinder on driver side, turning it to “UNLOCK” once unlocks the
driver side door lock actuator; turning it to “UNLOCK” again within 60 seconds after the first unlock operati on
unlocks all of the other doors. (SELECTIVE UNLOCK OPERATION)
Selective unlock operation mode can be changed using “DOOR LOCK-UNLOCK SET” mode in “WORK SUPPORT”. Refer to DLK-59, "
AUTOMATIC DOOR LOCK/UNLOCK FUNCTION (LOCK OPERATION)
The interlock door lock function is the function that locks all doors linked with the vehicle speed or shift position. It has 2 types as follows.
Vehicle Speed Sensing Auto Door Lock*1
All doors are locked when the vehicle speed reaches 15 miles or more.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is turned ON, all
doors are closed and the vehicle speed received from the combination meter via CAN communication
becomes 24 km/h (15 miles) or more.
DOOR LOCK : CONSULT-III Function (BCM - DOOR LOCK)".
P Range Interlock Door Lock
All doors are locked when shifting the selector lever from the P position to any position other than P.
BCM outputs the lock signal to all door lock actuators when it detects that the ignition switch is in the ON position and the shift signal received from the TCM via CAN communication is shifted from the P position to any

changed from ignition switch ON to OFF.
P Range Interlock Door Unlock
All doors are unlocked when shifting the selector lever from any position other than the P to P position.
BCM outputs the unlock signal to all door lock actuators when it detects that the ignition switch is in the ON
position and the shift signal received from TCM via CAN communication is shif ted from any positi on other than
the P to P position.

In the case of the back door fully open, operate the automatic back door switch, Intelligent Key
bottom or back door close switch. The automatic back door motor closes the back door to the
half-latch position, then the back door closure motor closes to the full latch position. Then, reverse the closure motor to the neutral position.
NOTE:
When the main switch is OFF, the power operation is not available by back door opener switch
and automatic back door clos e switch.
When the back door is close d to the half-l atch position, the motor driv es to rotate the latch leve r
and pulls it in from half latched to fully latched and automatically closes the door. Then, reverse
the closure motor to the neutral position.
During auto operation, if an object is detected by encoder pulse or touch sensor in the door's
path, a warning chime sounds and the back door operates in the reverse direction to prevent
pinching.
If the main switch is turned t o OFF during auto operatio n, the back door may be clos ed suddenly
because the operation is interrupted immediately when the operation cannot be continued because of the detection of a system malfunction. Therefore, operate the clutch intermittently to
stabilize the back door behavior and ensure safety.
