Optical Sensor System Inspection
EKS00FVD
1.
CHECK OPTICAL SENSOR INPUT SIGNAL
With CONSULT-II
Select "BCM" on CONSULT-II. With "OPTICAL SENSOR" data mon-
itor, check difference in the voltage when the optical sensor is illumi-
nated and not illuminated.
NOTE:
Optical sensor must be completely subjected to work lamp light. If
the optical sensor is insufficiently illuminated, the measured value
may not satisfy the standard.
Without CONSULT-II

OK or NG
OK
>> Inspection End.
NG
>> GO TO 2.
2.
CHECK OPTICAL SENSOR SIGNAL GROUND CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect BCM connector and optical sensor connector.
3.
Check continuity (open circuit) between BCM harness connector
M18 terminal 18 and optical sensor harness connector M145
terminal 3.
4.
Check continuity (short circuit) between BCM harness connector
M18 terminal 18 and ground.
OK or NG
OK
>> GO TO 3.
NG
>> Repair harness or connector.
3.
CHECK OPTICAL SENSOR SIGNAL CIRCUIT
1.
Check continuity (open circuit) between BCM harness connector
M20 terminal 58 and optical sensor harness connector M145
terminal 4.
2.
Check continuity (short circuit) between BCM harness connector
M20 terminal 58 and ground.
OK or NG
OK
>> Replace optical sensor. Refer to
. Recheck sensor output with CONSULT-II.
If NG, replace BCM. Refer to

System Description
EKS00FVG
Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The light-
ing switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.
When the lighting switch is placed in the fog lamp position, the BCM (body control module) receives input sig-
nal requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communi-
cated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication
lines. The CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil. When acti-
vated, this relay directs power to the front fog lamps.
OUTLINE
Power is supplied at all times
●
to ignition relay, located in the IPDM E/R, and
●
to front fog lamp relay, located in the IPDM E/R, and
●
through 20A fuse (No. 53, located in the IPDM E/R)
●
to CPU of the IPDM E/R, and
●
through 50A fusible link (letter g , located in the fuse and fusible link box)
●
to BCM terminal 70.
When the ignition switch is in ON or START position, power is supplied
●
to ignition relay, located in the IPDM E/R, and
●
through 10A fuse [No. 1, located in the fuse block (J/B)]
●
to BCM terminal 38.
Ground is supplied
●
to BCM terminal 67
●
through grounds M57, M61 and M79, and
●
to IPDM E/R terminals 38 and 59
●
through grounds E9, E15 and E24.
FOG LAMP OPERATION
The fog lamp switch is built into 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 20A fuse (No. 56, located in the IPDM E/R)
●
through IPDM E/R terminal 50
●
to front fog lamp LH terminal 1, and
●
through IPDM E/R terminal 51
●
to front fog lamp RH terminal 1.
Ground is supplied
●
to front fog lamp LH and RH terminal 2
●
through grounds E9, E15 and E24.
With power and ground supplied, the front fog lamps illuminate.
COMBINATION SWITCH READING FUNCTION
Refer to
BCS-3, "COMBINATION SWITCH READING FUNCTION"
EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), the fog lamp switch is ON, and the
ignition switch is turned from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the fog lamps (and headlamps) remain illuminated for 5 minutes, then the fog lamps (and
headlamps) are turned off.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.
