PARKING, LICENSE PLATE AND TAIL LAMPS
Revision: August 20072004 QX56
PARKING, LICENSE PLATE AND TAIL LAMPSPFP:26550
Component Parts and Harness Connector LocationEKS007CD
System DescriptionEKS007CE
Control of the parking, license plate, and tail lamp 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 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) across
the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay
coil. This relay, when energized, directs power to the parking, license plate and tail lamps, which then illumi-
nate.
Power is supplied at all times
to tail lamp relay, located in the IPDM E/R, and
through 20A fuse (No. 53, located in the IPDM E/R)
to CPU of the IPDM E/R, and
to ignition relay, located in the IPDM E/R, and
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38, and
to ignition relay, located in the IPDM E/R.
Ground is supplied
to BCM terminal 67
through grounds M57, M61 and M79, and
to IPDM E/R terminals 38 and 59
through grounds E9, E15 and E24.

OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM 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 across the CAN communication lines. The CPU in the IPDM E/R controls the
tail lamp relay coil, which when energized, directs power
through 10 A fuse (No. 37, located in the IPDM E/R)
through IPDM E/R terminal 57
to front combination lamp LH and RH terminal 3
to license plate lamps terminal +
to rear combination lamp LH and RH terminal 3.
Ground is supplied
to front combination lamp LH and RH terminal 4
through grounds E9, E15 and E24, and
to rear combination lamp LH terminal 1
through grounds B7 and B19, and
to rear combination lamp RH terminal 1 and
to license plate lamps terminal –
through grounds B117 and B132.
With power and ground supplied, the parking, license plate and tail lamps illuminate.
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 1ST (or 2ND) position, and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the parking, license and tail lamps remain illuminated for 5 minutes, then the parking,
license plate and tail lamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionEKS007CF
Refer to LAN-5, "CAN COMMUNICATION" .
