CONSULT-II FunctionsAKS007D4
CONSULT-II has a display function for work support, self-diagnosis, data monitor, and active test for each part
by combining data receiving and sending via the communication line from BCM.
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)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, refer to GI-40, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
BCM diagnosis part Check item, diagnosis mode Description
FLASHERData monitor Displays BCM input data in real time.
Active test Operation of electrical loads can be checked by sending driving signal to them.
