How to Proceed with Trouble DiagnosisNKS003QK
1. Confirm the symptom or customer complaint.
2. Understand operation description and function description. Refer to LT-135, "
System Description" .
3. Perform the preliminary check. Refer to LT- 1 5 1 , "
Preliminary Check" .
4. Perform self-diagnosis by CONSULT-II. Refer to LT-154, "
SELF-DIAG RESULTS" .
5. Check symptom and repair or replace the cause of malfunction.
6. Does the swivel control operate normally? If YES: GO TO 7. If NO: GO TO 4.
7. INSPECTION END

FOG LAMP OPERATION
The fog lamp switch is built in combination switch. The lighting switch must be in 2ND position or AUTO posi-
tion (headlamp is ON) and fog lamp switch must be ON for fog lamp operation.
With the fog lamp switch in the ON position, the CPU located in IPDM E/R grounds coil side of the fog lamp
relay. Fog lamp relay then directs power
through IPDM E/R terminal 37
to front fog lamp RH terminal 1,
through IPDM E/R terminal 36
to front fog lamp LH terminal 1.
Ground is supplied
to front fog lamp RH terminal 2
through grounds E22 and E43,
to front fog lamp LH terminal 2
through grounds E22 and E43.
With power and grounds supplied, the front fog lamps illuminate.
The unified meter and A/C amp. that received the front fog lamp request signal by BCM across the CAN com-
munication makes a front fog lamp indicator lamp turn on in combination meter.
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), 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 mode can be changed by the function setting of CONSULT-II.
CAN Communication System DescriptionNKS003R4
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 UnitNKS003R5

BCM then supplies power
through BCM terminal 45
to front combination lamp LH (turn signal) terminal 10
to side turn signal lamp LH terminal 1
to rear combination lamp LH (turn signal) terminal 3,
through BCM terminal 46
to front combination lamp RH (turn signal) terminal 10
to side turn signal lamp RH terminal 1

through grounds B5, B40 and B131.
The BCM also supplies input to unified meter and A/C amp. terminals 56 and 72 across the CAN communica-
tion lines.
The unified meter and A/C amp. which received the turn indicator signal makes the left and right turn signal
indicator turn on in combination meter.
With power and input supplied, the BCM controls the flashing of the hazard warning lamps.
