Bulb ReplacementBKS001P6
1. Turn lighting switch OFF.
2. Turn off the fender protector (front) to obtain work space between the fender protector and fender.
3. Disconnect front fog lamp connector.
4. Turn front for lamp bulb counterclockwise and unlock it.
CAUTION:

Never touch the glass of bulb directly by hand. Keep grease and other oily matters away from it.
Never touch bulb by hand while it is lit or right after being turned off. Burning may result.

Never leave bulb out of front fog lamp reflector for a long time because dust, moisture smoke, etc.
May affect the performance of front fog lamp. When replacing bulb, be sure to replace it with new
one.

Ground is supplied

to BCM terminal 52 and

to combination meter terminals 10, 11 and 12

through grounds M71and M72.
REAR FOG LAMP OPERATION
When the lighting switch is in rear fog lamp ON position and also in 1ST or 2ND position or AUTO position
(headlamp is ON), BCM detects RR FOG (ON) and the HEAD LAMP1, 2 (ON) or the AUTO LIGHT (ON) by
BCM combination switch reading function. And then, BCM sends rear fog lamp request signal (ON) through
CAN communication.
When receiving rear fog lamp request signal (ON), BCM supplies power

through BCM terminal 67

to rear fog lamp terminal 1.
Ground is supplied

to rear fog lamp terminal 2

through grounds B16 and B17.
With power and ground supplied, the rear fog lamp illuminates.
Unified meter and A/C amp. receives rear fog lamp request signal (ON) through CAN communication, and
make rear fog lamp indicator go ON in combination meter.
COMBINATION SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" .
EXTERIOR LAMP BATTERY SAVER CONTROL
Refer to LT- 1 9 7 , "EXTERIOR LAMP BATTERY SAVER CONTROL" .
CAN Communication System DescriptionBKS001PA
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.
CAN Communication UnitBKS001PB
Refer to LAN-49, "CAN System Specification Chart" .

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 position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-II. Refer to LT-
184, "DATA MONITOR" .
