GROUND CIRCUIT INSPECTION

Check the continuity between the following connector and ground.

OK or NG

OK

>> Power supply and ground circuit is OK.

NG

>> Repair or replace harness.

SYSTEM INSPECTION

When the Remote Keyless Entry System is malfunctioning, determine which part has caused the incident,
before carrying out the trouble diagnosis.

Using the following diagnosis flow chart, determine whether the electronic key or the vehicle component
(remote keyless entry receiver or BCM) has a malfunction and confirm the part to be checked.

REMOTE KEYLESS ENTRY SYSTEM

Inspection with CONSULT-II

CONSULT–II Function

NIS000UM

CONSULT-II executes the following functions by combining data received and command transmitted via the
communication line from BCM. IVMS communication inspection, work support (only function setting of seats
and steering wheel), self-diagnosis, data monitor, and active test display.

Description

IVMS-
COMM CHECK

IVMS-
COMM DIAGNOSIS

Diagnosis of continuity in the communication line(s), and of the function of the 
IVMS-communication interface between the body control module and the 
local control units, accomplished by transmitting a signal from the body con-
trol module to the local control units.

WAKE-UP DIAGNOSIS

Diagnosis of the“ wake-up” function of local control units by having a techni-
cian input the switch data into the local control unit that is in the temporary 
“sleep” condition.

Each system 
inspection

Work support

Changes the setting for each function.

Self-diagnosis results

Carries out self-diagnosis.

Data monitor

Displays data relative to the body control module (BCM) input signals and var-
ious control related data for each system.

Active test

Turns on/off actuators, relay and according to the commands transmitted by 
the CONSULT-II unit.

BCM PART NUMBER

Displays BCM part No.

 CONSULT-II BASIC OPERATION PROCEDURE

1.

With the ignition switch OFF, connect “CONSULT-II” and “CON-
SULT-II CONVERTER” to the data link connector on vehicle
side, and turn the ignition switch ON.

2.

Touch “START (NISSAN BASED VHCL)”.

3.

Touch “IVMS”.
If “IVMS” is not indicated, go to

GI-37, "CONSULT-II Data Link

Connector (DLC) Circuit"

 .

4.

Check the model specification, touch either “WITH SUNROOF”
or “WITHOUT SUNROOF”.

5.

Touch “OK”. If the selection is wrong, touch “CANCEL”.

6.

Select the desired part to be diagnosed on the “SELECT TEST ITEM” screen.

IVMS COMMUNICATION INSPECTION

IVMS contains the IVMS communication diagnosis and wake-up diagnosis.

IVMS Communication Diagnosis

IVMS communication diagnosis consists of the communication diagnosis, sleep diagnosis, and inactive
communication diagnosis between BCM and each local unit (LCU), and display the results on the CON-
SULT-ll screen.

REMOTE KEYLESS ENTRY SYSTEM

NOTE:
Sleep is a power saving function when a vehicle is stationary (all BCM related electrical equipment: OFF,
and the timer: OFF).

The function also stores the communication malfunction records and inactive communication records, and
displays the data on the CONSULT–II screen (Malfunction record diagnosis)

*: malfunctioning item record

Operation Procedure

1.

Touch “IVMS-COMM CHECK” on “SELECT TEST ITEM”.

2.

Touch “IVMS-COMM DIAGNOSIS” on “SELECT DIAG ITEM” screen.

3.

Touch “START” on “IVMS-COMM DIAGNOSIS” screen to start the diagnosis.

4.

After the diagnosis is completed, the malfunctioning system is displayed.

5.

When the malfunctioning items are displayed, touch “PRINT” to record.

6.

Touch “ERASE”.

7.

Perform the communication inspection again to make sure that any malfunctioning item is displayed.

8.

Check the displayed items. 

Wake-Up Diagnosis

The wake-up diagnosis is carried out when BCM detects the wake-up signal from each local unit (LCU). When
the switch shown on the screen is operated as instructed, each local control unit (LCU) outputs the wake-up
signal. If BCM cannot detect a wake-up signal, it is judged malfunctioning. The malfunctioning local control
unit (LCU) is displayed on the screen.
NOTE:
If any unspecified switch is operated, “Switch data not match” is displayed as a malfunctioning system.

Operation Procedure

1.

Touch “IVMS-COMM CHECK” on “SELECT TEST ITEM” screen.

2.

Touch “WAKE-UP DIAGNOSIS” on “SELECT DIAG ITEM” screen.

3.

Touch “START” on “WAKE-UP DIAGNOSIS” screen to start the diagnosis.

4.

Touch “NEXT” to select the local control unit (LCU) to be diagnosed.

5.

Check that any malfunction is displayed. If necessary, touch “PRINT” to record.

6.

Preform the inspection to the malfunctioning item.

Description

Communication malfunction

COMM DATA

Communicating with each LCU is judged sound when the communication is nor-
mally completed and the transmitted data and received data are identically the 
same. In other cases, it is judged malfunctioning. If the communication is inactive, 
no diagnosis result is displayed.

Inactive communication

NO RESPONSE

Communicating with each LCU is judged sound when at least one time communi-
cation is normally completed within three trials. In other cases, it is judged mal-
functioning.

Sleep malfunction

SLEEP

Make sure that each LCU enters sleep mode.

Communication malfunction*

PAST COMM
DATA

The records when communication signal malfunctions were continuously 
detected while the communication was normal are displayed. Or the records 
when a malfunction is detected during the past sleep mode are displayed.

Inactive communication*

PAST NO
RESPONSE

The records when inactive communications were continuously detected while the 
communication was normal are displayed.
