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 parking, license plate, side ma rker and tail lamps to illuminate. This input signal is
communicated to the IPDM E/R through the CAN communi cation. The CPU located in the IPDM E/R controls
the tail lamp relay coil, which when energized, directs power.

PARKING, LICENSE PLATE AND TAIL LAMPS
With power and ground supplied, the parking, license plate, side marker and tail lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-4, "System Description".
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST (or 2ND) position, and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the parking, license, side marker and tail lamps remain illuminated for 5 minutes, then the
parking, license plate, side marker and tail lamps are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-III.
CAN Communication System DescriptionINFOID:0000000001328384
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitINFOID:0000000001328385
Refer to LAN-43, "CAN System Specification Chart".
