ILLUMINATION
System DescriptionINFOID:0000000001704480
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 (with 4-speed A/T)
• to CVT device terminal 3 (with CVT)
• to hazard switch terminal 3
• to combination meter terminal 12
• to door mirror remote control switch terminal 16, and
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 (with 4-speed A/T)
• to CVT device terminal 3 (with CVT)
• to hazard switch terminal 4
