Combination Switch InspectionNKS004YQ
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-III
1. Select "COMBI SW" of BCM data monitor item.
2. 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
“LIGHT SW 1 ST” in System 5, to which the HI BEAM switch belongs, turn ON-OFF normally.
Without CONSULT-III
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 “LIGHT
SW 1 ST” 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.

PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationNKS004YZ
System DescriptionNKS004Z0
Control of parking, license plate, side maker and tail lamps operation is dependent upon the position of lighting
switch (combination switch). When the lighting switch is in the 1ST position, the BCM (body control module)
receives input signal requesting the parking, license plate, side marker and tail lamps to illuminate. This input
signal is communicated to the IPDM E/R (intelligent power distribution module engine room) through CAN
communication. The CPU (central processing unit) located in the IPDM E/R controls the tail lamp relay coil
and daytime light relay
* coil. These relay, when energized, directs power to parking, license plate, side marker
and tail lamps, which then illuminate.
NOTE:
Daytime light relay*: Canada models
OUTLINE
Power is supplied at all times

through 10A fuse (No.71, located in IPDM E/R)

With ignition switch in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

through grounds E17, E43 and F152 (without VDC system, navigation system and telephone).
OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, the BCM receives input signal requesting the parking,
license plate, side marker and tail lamps to illuminate. This input is communicated to the IPDM E/R through
the CAN communication lines. The CPU located in the IPDM E/R controls the tail lamp relay coil and daytime
light relay
* coil. These relay, when energized, directs power to parking, license plate, side marker and tail
lamps, which when energized, directs power

through IPDM E/R terminal 22 (USA models)

through daytime light relay terminal 5 (Canada models)

to front combination lamp RH terminals 6

to rear combination lamp LH terminals 2

to rear combination lamp RH terminals 2

to front combination lamp RH terminal 8

through grounds E17, E43 and B102 (with VDC system, navigation system or telephone)

through grounds E17, E43 and F152 (without VDC system, navigation system and telephone),

to rear combination lamp LH terminals 3

to rear combination lamp RH terminals 3

to license plate lamp LH terminal 1, and

to license plate lamp RH terminal 1

through grounds B5, B6, D105 and T14 (Coupe models)

through grounds B5, B6 and T14 (Roadster models).
With power and ground supplied, parking, license plate side marker and tail lamps illuminate.

Daytime light relay*: Canada models
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the parking, license, side marker and tail lamps remain illuminated for 5 minutes, then the
headlamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.

CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-III. Refer to LT- 9 1 , "
