turn signal indicator. The unified meter control unit in the combination meter supplies ground to the left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp
When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power

• to rear combination lamp RH terminal 6.
Ground is supplied
• to front combination lamp RH terminal 5
• through grounds E15 and E24,
• to rear combination lamp RH terminal 1
• through grounds B117, B132 (all models) and D402 (with hatchback).
The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the right
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the right turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.

System DescriptionINFOID:0000000001704448
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 controls 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 position, the BCM receives an input signal requesting parking,
license plate and tail lamps to illuminate. This input signal is communicated to the IPDM E/R via the CAN com-
munication lines. The CPU, located in the IPDM E/R, controls 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

INTERIOR ROOM LAMP TIMER OPERATION
Without Intelligent Key System
When room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 seconds) for room lamp ON/OFF.
In addition, when the interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 sec-
ond.
Power is supplied
• through 10A fuse [No. 14, located in fuse block (J/B)]
• to key switch and key lock solenoid terminal 2.
When the key is removed from ignition key cylinder (key switch OFF), power will not be supplied to BCM termi-
nal 37.
When front door key cylinder switch LH is unlocked, ground is supplied
• to BCM terminal 7
• through front door key cylinder switch LH terminal 3
• through front door key cylinder switch LH terminal 2
• through grounds M57 and M61.
At the time that front door LH is opened, BCM detects that front door LH is unlocked. It determines that interior
room lamp timer operation condition is met, and turns the room lamp ON for 30 seconds.
When key is in ignition key cylinder (key switch ON),
Power is supplied
• through key switch and key lock solenoid terminal 1
• to BCM terminal 37.
When key is removed from key switch and key lock solenoid (key switch OFF), the power supply to BCM ter-
minal 37 is terminated. BCM detects that key has been removed, determines that interior room lamp timer
conditions are met, and turns the room lamp ON for 30 seconds.
When front door LH opens → closes, and the key is not inserted in the key switch and key lock solenoid (key
switch OFF), voltage at BCM terminal 47 changes between 0V (door open) → 12V (door closed). The BCM
determines that conditions for room lamp operation are met and turns the room lamp ON for 30 seconds.
Interior room lamp timer control is canceled under the following conditions:
• Front door LH is locked (locked front door key cylinder switch LH).
• Front door LH is opened (front door switch LH).
• Ignition switch ON.
With Intelligent Key System
When the room lamp switch is in DOOR position, and when all conditions below are met, BCM performs timer
control (maximum 30 second) for room lamp ON/OFF.
In addition, when interior room lamp turns ON or OFF there is gradual brightening or dimming over 1 second.
Power is supplied
