through 10A fuse [No. 1, located in fuse block (J/B)]
●
to BCM (body control module) terminal 35
●
through 10A fuse [No. 80, located in IPDM E/R (intelligent power distribution module engine room)]
●
to CPU (central processing unit) [located in IPDM E/R (intelligent power distribution module engine room)
When the ignition switch is in ACC or ON position, power is supplied
●
through 10A fuse [No. 6, located in fuse block (J/B)]
●
to BCM (body control module) terminal 36
Ground is supplied
●
to BCM (body control module) terminal 8
●
through grounds E13, E26 and E28
●
to IPDM E/R (intelligent power distribution module engine room) terminal 14 and 45
●
through grounds E13, E26 and E28.
FOG LAMP OPERATION
The fog lamp switch is built in the combination switch. The lighting switch must be in the 2ND position or
AUTO position (LOW beam is ON) and the fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU of the IPDM E/R grounds the coil side of the fog lamp
relay. The fog lamp relay then directs power
●
through IPDM E/R terminal 32
●
to front fog lamp LH terminal 1
●
through IPDM E/R terminal 29
●
to front fog lamp RH terminal 1
Ground is supplied
●
to front fog lamp LH terminal 2
●
through grounds E13, E26 and E28, and
●
to front fog lamp RH terminal 2
●
through grounds E13, E26 and E28.
With power and grounds supplied, the front fog lamps illuminate.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, power is
supplied
●
through IPDM E/R terminal 32
●
to front fog lamp LH terminal 1
●
through IPDM E/R terminal 29
●
to front fog lamp RH terminal 1.
Ground is supplied
●
to front fog lamp LH terminal 2
●
through grounds E13, E26 and E28, and
●
to front fog lamp RH terminal 2
●
through grounds E13, E26 and E28.
With power and grounds supplied, the front fog lamps illuminate.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned from
ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, then the headlamps are turned off.
Exterior lamp battery saver control made can be changed by the function setting of CONSULT-II.
COMBINATION SWITCH READING FUNCTION
Refer to
LT-251, "Combination Switch Reading Function"
.
AUTO LIGHT OPERATION
For auto light operation, refer to
in “AUTO LIGHT SYSTEM”.

CAN Communication System Description
AKS007NG
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.
