ILLUMINATION
Revision: November 20092006 QX56

to combination meter terminal 8
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. 59, located in the fuse and relay box)

to BCM terminal 38, and

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

to combination meter terminal 24.
Ground is supplied

to BCM terminal 67 and

to combination meter terminal 17

through grounds M57, M61 and M79, and

to IPDM E/R terminals 38 and 59

through grounds E9, E15 and E24.
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. 36, located in the IPDM E/R)

through IPDM E/R terminal 49

to illumination control switch terminal 1

to power liftgate switch terminal 3

to front room/map lamp assembly (console box illumination) terminal 7

to hazard switch terminal 3

to rear sonar system OFF switch terminal 3

to glove box lamp terminal 1

to display control unit terminal 14

to 4WD shift switch terminal 7 (with 4-wheel drive)

to front air control terminal 23

to rear power vent window switch terminal 5

to DVD player terminal 12 (with DVD entertainment system)

to NAVI control unit terminal 61

to pedal adjusting switch terminal 5

to electric brake (pre-wiring) terminal 4 (with trailer tow)

to front and rear heated seat switch LH and RH terminal 5

to A/T device terminal 11

to VDC OFF switch terminal 3

to tow mode switch terminal 3

to headlamp aiming switch terminal 3

to clock terminal 3, and

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

through IPDM E/R terminal 57

to AV switch terminal 3

to audio unit terminal 8

to rear air control terminal 1 and

to rear audio remote control unit terminal 6.
Illumination is controlled

through illumination control switch terminal 2

to power liftgate switch terminal 4

to rear air control terminal 3 and

to rear audio remote control unit terminal 15

through grounds B117 and B132.
With power and ground supplied, illumination lamps illuminate.
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.
