System Description

EKS00FWP

Control of the parking, front side marker, license plate, and tail lamp operation is dependent upon the position
of the lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM
(body control module) receives input signal requesting the parking, front side marker, license plate and tail
lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module
engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R con-
trols the tail lamp relay coil. This relay, when energized, directs power to the parking, front side marker, license
plate and tail lamps, which then illuminate. 
Power is supplied at all times

●

to ignition relay, located in the IPDM E/R, and

●

to tail lamp relay, located in the IPDM E/R, and

●

through 20A fuse (No. 53, located in the IPDM E/R)

●

to CPU of the IPDM E/R, and

●

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

●

to BCM terminal 70.

With the ignition switch in the ON or START position, power is supplied

●

to ignition relay, located in the IPDM E/R.

●

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

●

to BCM terminal 38 and

Ground is supplied

●

to BCM terminal 67

●

through grounds M57, M61 and M79, and

●

to IPDM E/R terminals 38 and 59

●

through grounds E9, E15 and E24.

OPERATION BY LIGHTING SWITCH

With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the parking, front side marker, license plate and tail lamps to illuminate. This input sig-
nal is communicated to the IPDM E/R across the CAN communication lines. The CPU in the IPDM E/R con-
trols the tail lamp relay coil, which when energized, directs power
