CONSULT-II Functions (BCM)AKS007MJ

CONSULT-II executes the following functions by combining data reception and command transmission via
the communication line from BCM. Work support, self-diagnosis, data monitor, and active test 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 data link connector, then turn igni-
tion switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
