ILLUMINATION

ILLUMINATIONPFP:27545
System DescriptionEKS00HZU
The control of the illumination lamps operation is dependent upon the position of the lighting switch. When the
lighting switch is placed in the 1ST or 2ND position, the BCM (body control module) receives input signal
requesting the illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent
power distribution module engine room) across CAN communication lines. CPU (central processing unit)
located in the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the illu-
mination 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 CPU located in IPDM E/R,
through 40A fusible link (letter g , located in fuse and fusible link box)
to BCM terminal 70, and
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
to ignition relay, located in IPDM E/R, and
through 10A fuse [No. 6, located in fuse block (J/B)]
to BCM terminal 38.
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 M57 and M61, and
to IPDM E/R terminals 39 and 59
through grounds E15 and E24.
ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position, BCM receives input signal requesting the illumination
lamps to illuminate. This input signal is communicated to IPDM E/R across CAN communication lines. CPU
located in the IPDM E/R controls the tail lamp relay coil, which, when energized, directs power
through 10A fuse (No. 37, located in IPDM E/R)
through IPDM E/R terminal 29
to microphone terminal 3 (with Bluetooth)
to illumination control switch terminal 1
to glove box lamp terminal 1 (with glovebox lamp)
to audio unit terminal 9
to front air control terminal 5
to A/T device terminal 3 (without M/T)
to hazard switch terminal 3
to combination meter terminal 12
to door mirror remote control switch terminal 16, and
to main power window and door lock/unlock switch terminal 4.
Ground is supplied
to microphone terminal 2 (with Bluetooth)
to glove box lamp terminal 2 (with glove box lamp), and

to illumination control switch terminal 3
through grounds M57 and M61.
The illumination control switch controls illumination intensity by varying the ground to the following
through illumination control switch terminal 2
to audio unit terminal 8
to front air control terminal 6
to A/T device terminal 4 (without M/T)
to hazard switch terminal 4
to combination meter terminal 15,
to door mirror remote control switch,
to main power window and door lock/unlock switch terminal 10.
With power and ground supplied, illumination lamps illuminate.
