1.SYSTEM CHECK
Referring to table below, check to which system the malfunctioning switch belongs.
>> 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 “LIGHT SW 1ST” 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 “LIGHT
SW 1ST” in system 5, to which HI BEAM switch belongs, turn ON-OFF normally.

PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationEKS00P9C
System DescriptionEKS00P9D
Control of the clarence, license plate, and tail lamps operation is dependent upon the position of the lighting
switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control
module) receives input signal requesting the clarence, license plate and tail lamps to illuminate. This input sig-
nal is communicated to the IPDM E/R (intelligent power distribution module engine room) through the CAN
communication. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. This relay,
when energized, directs power to the clarence, license plate and tail lamps, which then illuminate.
OUTLINE
Power is supplied at all times
lto ignition relay (located in IPDM E/R) and
lto tail lamp relay (located in IPDM E/R), from battery directly,
lthrough 20A fuse (No. 52, located in IPDM E/R) and
lthrough 20A fuse (No. 53, located in IPDM E/R)
lto CPU (located in IPDM E/R),
lthrough 50A fusible link (letter G, located in fuse and fusible link box)
lto BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
lto ignition relay (located in IPDM E/R),
lthrough 10A fuse [No. 1, located in fuse block (J/B)]
lto BCM terminal 3.
Ground is supplied
lto BCM terminal 55
lthrough grounds M21, M80 and M83,
lto IPDM E/R terminals 38 and 59

OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST position, 2ND position or AUTO position (when the auto light system is acti-
vated), the BCM receives input signal requesting the clarence, license plate and tail lamps to illuminate. This
input signal is communicated to the IPDM E/R through the CAN communication. The CPU in the IPDM E/R
controls the tail lamp relay coil, which when energized, directs power
lthrough IPDM E/R terminal 28
lto front combination lamp LH terminal 1,
lthrough IPDM E/R terminal 49
lto front combination lamp RH terminal 1,
lthrough IPDM E/R terminal 57
lto rear combination lamp RH and LH terminals 1 and
lto license plate lamp RH and LH terminals 1.
Ground is supplied
lto front combination lamp RH and LH terminals 2
lto rear combination lamp RH and LH terminals 3 and
lto license plate lamp RH and LH terminals 2
lthrough grounds E21, E41 and E61.
With power and ground supplied, the clarence, license plate and tail lamps illuminate.
