Component Parts and Harness Connector LocationINFOID:0000000003533434
System DescriptionINFOID:0000000003533435
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 ignition relay, located in the IPDM E/R,
• to tail lamp relay, located in the IPDM E/R,
• through 20A fuse (No. 53, located in the IPDM E/R)
• to CPU of 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
• to ignition relay, located in the IPDM E/R, and
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 of 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 1 and
• 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,
• to rear combination lamp LH terminal 1
• through grounds B7 and B19,
• to rear combination lamp RH terminal 1 and
• to license plate lamps terminal 2
• 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, "System Description" .
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.
