to ignition relay, located in the IPDM E/R.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse (No. 59, located in the fuse and relay box)
to BCM terminal 38, and
to ignition relay in the IPDM E/R, and
through 10A fuse [No. 14, 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. 36, located in the IPDM E/R)
through IPDM E/R terminal 49
