Component Parts and Harness Connector LocationBKS001NJ
System DescriptionBKS001NK

BCM (Body Control Module) controls low beam headlamp and high beam headlamp operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates headlamp bulbs according to
CAN communication signals from BCM.

Unified meter and A/C amp. operates high beam indicator lamp according to CAN communication signals
from BCM.
OUTLINE
Power is supplied at all times

to headlamp high relay (located in IPDM E/R)

to headlamp low relay (located in IPDM E/R) and

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

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

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

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.
