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" .

Combination Switch InspectionAKS007G7
1. SYSTEM CHECK
1. Referring to table below, check which system malfunctioning switch belongs to.
>> Check the system to which malfunctioning switch belongs, and GO TO 2.
2. SYSTEM CHECK
With CONSULT-II
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. Connect CONSULT-II, and select “COMB SW” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR”.
3. Select “START”, and confirm that other switches in malfunction-
ing system operate normally.
Example: When auto light switch is malfunctioning, confirm that
“FRONT WIPER LOW” and “FRONT WIPER INT” in System 3,
to which the auto light switch belongs, turn ON-OFF normally.
Without CONSULT-II
Operating combination switch, confirm that other switches in malfunctioning system operate normally.
Example: When auto light switch is malfunctioning, confirm that FRONT WIPER LOW and FRONT WIPER
INT in System 3, to which the auto light switch belongs, operate normally.
Check results
Other switches in malfunctioning system operate normally.>>Replace lighting switch or wiper switch.
Other switches in malfunctioning system do not operate normally.>>GO TO 3.
