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 and tail lamps to illuminate. This input signal is communi-
cated to the IPDM E/R across the CAN communication lines. The CPU located in the IPDM E/R controls the
tail lamp relay coil, which when energized, directs power

●

through IPDM E/R terminal 21

●

to front combination lamp LH and RH terminals 5 (parking)

●

to front combination lamp LH and RH terminals 7 (side marker)

●

to rear combination lamp LH and RH terminals 1 (tail and side marker)

●

to license plate lamp LH and RH terminals 1.

Ground is supplied at all times

●

to front combination lamp LH and RH terminals 1 (parking and side marker)

●

through grounds E22 and E43,

EXTERIOR LAMP BATTERY SAVER CONTROL

from ON or ACC to OFF, battery saver control feature is activated.
Under this condition, parking, license plate, 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-II.

CAN Communication System Description

NKS003SJ

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 speed 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 CAN 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.
