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

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.
