System Description

EKS00FXL

Control of the illumination lamps operation is dependent upon the position of the lighting switch (combination
switch). When the lighting switch is placed in the 1ST or 2ND position (or if the auto light system is activated)
the BCM (body control module) receives input signal requesting the illumination 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 controls the tail lamp relay coil. This
relay, when energized, directs power to the illumination 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 50A fusible link (letter g , located in the fuse and fusible link box)

●

to BCM terminal 70, and

●

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

●

to CPU of the IPDM E/R, and

●

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

●

to combination meter terminal 3.

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

●

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

●

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

ILLUMINATION 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 illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power

●

through 10A fuse (No. 37, located in the IPDM E/R)

EXTERIOR LAMP BATTERY SAVER CONTROL

When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then the illumination lamps are
turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by the battery saver control, the illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
