Component Parts and Harness Connector LocationINFOID:0000000001328382
System DescriptionINFOID:0000000001328383
Control of the parking, license plate, side marker 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 parki ng, license plate, side marker and tail lamps to illumi-
nate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room)
through the CAN communication lines. CPU (central processi ng unit) located in the IPDM E/R controls the tail
lamp relay coil. This relay, when energized, directs pow er to the parking, license plate, side marker and tail
lamps, which then illuminate.
The current that flows by Rear combination lamp cont rol unit is controlled, and a tail lamp (LED) is made to
turn ON.
OUT LINE
Power is supplied at all times
 to ignition relay, located in IP DM E/R, from battery direct,
 through 10A fuse (No. 71, located in IPDM E/R)
 to tail lamp relay, located in IPDM E/R and
 to CPU located in IPDM E/R,
 through 15A fuse (No. 78, located in IPDM E/R)
 to CPU located in IPDM E/R.
 through 50A fusible link (letter M, located in fuse, fusible link and relay box)

CAUTION:
 Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.
 Turn wiper intermittent dial posi tion to 4 except when checking wavef orm or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-III. Refer to LT-
