Combination Switch Inspection
NKS002TU
1.
SYSTEM CHECK
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 the 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, and confirm that other switches in malfunctioning system operate normally.
Example: When the 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.

STOP LAMP
Revision: 2006 August
2006 Murano
STOP LAMP OPERATION
When the stop lamp switch is depressed supplies power
●
through stop lamp switch terminal 4
●
to rear combination lamp control unit terminal 2
●
to high-mounted stop lamp terminal 1 and
●
to unified meter and A/C amp. terminal 6.
When receiving the stop lamp signal, rear combination lamp control unit detects the stop lamp ON, then rear
combination lamp control unit outputs the rear combination lamp drive signal RH and LH (stop lamp output).
Rear combination lamp control unit supplies power
●
through rear combination lamp control unit terminal 7
●
to rear combination lamp RH terminal 1,
●
through rear combination lamp control unit terminal 5
●
to rear combination lamp LH terminal 1.
Ground is supplied
●
to high-mounted stop lamp terminal 2
●
through grounds B7 and B20,
●
to rear combination lamp RH terminal 4
●
through rear combination lamp control unit terminal 14,
●
to rear combination lamp LH terminal 4
●
through rear combination lamp control unit terminal 13.
With power and ground supplied, stop lamp and high-mounted stop lamp illuminate.
