OPERATION PROCEDURE
1. Touch “START (NISSAN BASED VHCL)”, “ABS”, “DATA MONITOR” in order on CONSULT-II screen.
CAUTION:
When “START (NISSAN BASED VHCL)” is touched immediately after starting engine or turning on
the ignition switch, “ABS” might not be displayed in the system selection screen. In this case,
repeat the operation from step 1.
2. At the monitor item selection screen, touch one of the items “ECU INPUT SIGNALS”, “MAIN SIGNALS” or
“SELECTION FROM MENU”.
3. Touch “START” to proceed to the data monitor screen.
DISPLAY ITEM LIST
CAUTION:
The display shows the control unit calculation data, so a normal value might be displayed even in the
event the output circuit (harness) is open or short - circuited.

CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionNAS0007S
CONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.
Refer to “CONSULT-II Software Operation Manual” for more information.

Example of Filling in Check Sheet When Initial Conditions Are Reproduced
1. Put a check mark to “No indication” if some of unit names listed on the column of diagnosis system selec-
tion screen of a check sheet table are not displayed on “SELECT SYSTEM” screen attached to the check
sheet.
NOTE:
Put a check mark to “No indication” of BCM and AUTO DRIVE POS. because BCM and AUTO DRIVE
POS. is not displayed on “SELECT SYSTEM” screen.
2. Confirm the unit name that “UNKWN” is displayed from the copy of “CAN DIAG SUPPORT MNTR” screen
of “ENGINE” attached to the check sheet, and then put a check mark to the check sheet table.
NOTE:
In “CAN DIAG SUPPORT MNTR” screen, “UNKWN” is displayed on “VDC/TCS/ABS”, “METER/M&A” and
“IPDM E/R”. Put a check mark to it.
3. Confirm the unit name that “UNKWN” is displayed on the copy of “CAN DIAG SUPPORT MNTR” screen
of “A/T” and “AIR PRESSURE MONITOR” as well as “ENGINE”. And then, put a check mark to the check
sheet table.
NOTE:
For “A/T”, “UNKWN” is displayed on “VDC/TCS/ABS”, “METER/M&A”, “ICC/e4WD” and “AWD/4WD”.
But put a check mark to “VDC/TCS/ABS” and “METER/M&A” because “UNKWN” is listed on the col-
umn of reception diagnosis of the check sheet table.
For “AIR PRESSURE MONITOR”, “UNKWN” is displayed on “ECM”. Put a check mark to it.

And then, put a check mark to the check sheet table.
NOTE:
For “INTELLIGENT KEY”, “UNKWN” is displayed on “ECM”, “BCM/SEC” and “TCM”. Put a check mark
to it.
For “METER A/C AMP”, “UNKWN” is displayed on “ECM”, “TCM” and “BCM/SEC”. Put a check mark to
