CONSULT-II Functions (BCM)NKS003S8
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
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, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, check power supply and ground of
BCM. If it is normal, refer to GI-40, "
CONSULT-II Data Link Con-
nector (DLC) Circuit" .
4. Touch “COMB SW”.
BCM diagnosis part Diagnosis mode Description
COMB SW DATA MONITOR Displays BCM input data in real time.

Combination Switch InspectionNKS003S9
1. SYSTEM CHECK
Referring to table below, check the system to which malfunctioning switch belongs.
>> Check the system to which malfunctioning switch belongs, and then 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 the HI BEAM switch is malfunctioning, confirm
that “TURN RH”, “HEAD LAMP 1” and “TAIL LAMP SW” in Sys-
tem 5, to which the HI BEAM switch belongs, turn ON-OFF nor-
mally.
Without CONSULT-II
Operating combination switch, and confirm that other switches in malfunctioning system operate normally.
Example: When the HI BEAM switch is malfunctioning, confirm that “TURN RH”, “HEAD LAMP 1” and “TAIL
LAMP SW” in System 5, to which HI BEAM switch belongs, turn ON-OFF 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.

3. CHECK HARNESS
1. Turn ignition switch OFF.
2. Disconnect BCM and combination switch connectors.
3. Check for continuity between BCM harness connector (A) of the suspect system and the corresponding
combination switch connector (B).
4. Check for continuity between each of BCM harness connector in suspect malfunctioning system and
ground.
OK or NG
OK >> GO TO 4.
NG >> Check harness between BCM and combination switch for open or short circuit.
