CONSULT-II

AJS000YX

CONSULT-II executes the following functions by combining data reception and command transmission via the
communication line from BCM data monitor display.

CONSULT-II BASIC OPERATION

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

1.

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

2.

Touch “START (NISSAN BASED VHCL)”.

3.

Touch “BCM” on “SELECT SYSTEM” screen. If “BCM” is not
indicated, go to
