Without CONSULT-II
GO TO 3.
OK or NG
OK >> Replace BCM. Refer to BCS-15, "Removal and Installa-
tion of BCM" .

Combination Switch Reading FunctionAKS007G5
For details, refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" in “BCS” section.
CONSULT-II FunctionAKS007G6
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" .
