System Description
AKS007NF
Daytime light system turns ON daytime light lamps (front fog lamps) while driving. Daytime light lamps are not
turned ON if engine is activated with parking brake ON. Release parking brake to turn on daytime light lamps.
The lamps turn OFF when lighting switch is in the 2ND position or AUTO position (headlamp is ON) and when
lighting switch is in the PASSING position. (Daytime light lamps are not turned off only by parking brake itself.)
A parking brake signal and engine run or stop signal are sent to BCM (body control module) by CAN commu-
nication line, and control daytime light system.

Power is supplied at all times
●
to ignition relay, located in IPDM E/R (intelligent power distribution module engine room), from battery
direct,

●
to front fog lamp relay located in IPDM E/R,
●
through 10A fuse (No. 71, located in IPDM E/R)
●
to CPU (central processing unit) 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 F, located in fuse and fusible link block)

●
to BCM terminal 42,
●
through 10A fuse [No. 21, located in fuse block (J/B)]
●
to combination meter terminal 21.
When the ignition switch is in ON or START position, power is supplied
●
to ignition relay, located in IPDM E/R, from battery direct,
●
through 10A fuse [No. 1, located in fuse block (J/B)]
●
to BCM terminal 38,
●
through 10A fuse [No. 14, located in fuse block (J/B)]
●
to combination meter terminal 20.
When the ignition switch is in ACC or ON position, power is supplied
●

●
to BCM terminal 11.
Ground is supplied
●
to BCM terminal 52

●
through grounds E13, E26 and E28,
●
to combination meter terminals 22, 23 and 24
●
through grounds M14 and M78.
DAYTIME LIGHT OPERATION
With the engine running, the lighting switch in the OFF or 1ST position and parking brake released, the CPU
located in 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 37
●
to front fog lamp LH terminal 1,
●
through IPDM E/R terminal 36
●
to front fog lamp RH terminal 1.
Ground is supplied
●
to front fog lamp LH terminal 2
●
through grounds E13, E26 and E28,
●
to front fog lamp RH terminal 2
●
through grounds E13, E26 and E28.
With power and grounds supplied, the front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to
BCS-3, "COMBINATION SWITCH READING FUNCTION"
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 front fog lamps remain illuminated for 5 minutes, and then the front fog lamps are
turned off.
Exterior lamp battery saver control made can be changed by the function setting of CONSULT-II.

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.
