System DescriptionBKS001RI

BCM (Body Control Module) controls illumination lamp operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates illumination lamps according to
CAN communication signals from BCM.
OUTLINE
Power is supplied at all times

to ignition relay (located in IPDM E/R), from battery direct,

through 50A fusible link (letter M, located in fuse and fusible link box)

to BCM terminal 55,

through 15A fuse [No. 17, located in fuse block (J/B)]

to BCM terminal 42 and

to combination meter terminal 7,

through 15A fuse (No. 71, located in IPDM E/R)

to tail lamp relay (located in IPDM E/R) and

to CPU (central processing unit) in IPDM E/R

through 15A fuse (No. 78, located in IPDM E/R)

to CPU in IPDM E/R,

through 10A fuse [No. 19, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 21.
With the ignition switch in the ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

through 10A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through 10A fuse [No. 12, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 22,

through 10A fuse [No. 14, located in fuse block (J/B)]

to combination meter terminal 8.
With the ignition switch in the ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

to unified meter and A/C amp. terminals 29 and 30, and

to combination meter terminals 10, 11, and 12

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
ILLUMINATION OPERATION BY LIGHTING SWITCH
When the lighting switch is in 1ST position, BCM detects the LIGHTING SWITCH 1ST POSITION (ON) by
BCM combination switch reading function. And then, BCM sends position light request signal (ON) through
CAN communication and MR output signal.
When receiving position light request signal (ON), IPDM E/R turns ON tail lamp relay in IPDM E/R. And then
supplies power

through IPDM E/R terminal 22

to glove box lamp terminal 1

to A/T device illumination terminal 1 (with A/T)

to CVT device illumination terminal 1 (with CVT)

to rear sunshade front switch (illumination) terminal 5 (with rear sunshade)
