OPERATION PROCEDURE
1. After ignition switch OFF, perform “CONSULT-II Starting Procedure”. Refer to GI-38, "CONSULT-II Start
Procedure" .
2. Touch “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.
3. At the monitor item selection screen, touch one of the items “ECU INPUT SIGNALS”, “MAIN SIGNALS” or
“SELECTION FROM MENU”.
4. Touch “START” to proceed to the data monitor screen.

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.
