System Description INFOID:0000000004306608
The control of the parking, license plate and tail lamp operation is dependent upon the position of lighting
switch. When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input
signal requesting the parking, license plate and tail lamps to illuminate. This input signal is communicated to
the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU
(central processing unit) located in the IPDM E/R contro ls the tail lamp relay coil. This relay, when energized,
directs power to parking, license plate and tail lamps, which then illuminate.
Power is supplied at all times
• to ignition relay located in IPDM E/R,
• to tail lamp relay located in IPDM E/R,
• through 15A fuse (No. 52, located in IPDM E/R) and
• through 20A fuse (No. 53, located in IPDM E/R)
• to the CPU located in the IPDM E/R,
• through 40A fusible link (letter g , located in fuse and fusible link block)
• to BCM terminal 70,
• through 10A fuse [No. 8, located in fuse block (J/B)],
• to BCM terminal 57.
With the ignition switch in the ON or START position, power is supplied
• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 38,
• to ignition relay located in IPDM E/R and
• through the ignition relay
• to the CPU of the IPDM E/R.
With the ignition switch in the ACC or ON position, power is supplied
• through 10A fuse [No. 20, located in fuse block (J/B)]
• to BCM terminal 11.
Ground is supplied
• to BCM terminal 67
• through grounds M20 and M61,
• to IPDM E/R terminals 59 and 39
• through grounds E15 and E24.
OPERATION BY LIGHTING SWITCH With the lighting switch in the 1ST or 2ND positi on, the BCM receives an input signal requesting parking,
license plate and tail lamps to illuminate. This input si gnal is communicated to the IPDM E/R via the CAN com-
munication lines. The CPU, located in the IPDM E/R, c ontrols the tail lamp relay coil. When energized, the tail
lamp relay directs power
• through 10A fuse (No. 37, located in IPDM E/R),
• through IPDM E/R terminal 26
• to front combination lamp LH terminal 6, and
• through IPDM E/R terminal 27 1. IPDM E/R E45, E46 and E48 2. BCM M18 and M20 (view with glove

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in t he 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 la mps 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-III.
