INFOID:0000000009463551
TURN SIGNAL AND HAZARD WARNING LAMPS : System DescriptionINFOID:0000000009463552
TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal swit ch) is in LH or RH turn position with the ignition
switch in the ON position, the BCM receives input reques ting the turn RH or turn LH lamps to illuminate. The
BCM controls the turn signal power to the respective turn signal lamp. The BCM also sends a turn indicator
signal ON request via the CAN communication lines to the combination meter. The combination meter then
activates the appropriate turn signal indicator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in the ON position, the BC M receives input requesting the hazard lamps illuminate.
The BCM controls the turn signal power to both the LH and RH turn signal lamps. The BCM sends a hazard
indicator signal ON request via the CAN communication lines to the combination meter. The combination
meter then activates both the LH and RH turn signal indicators and audible buzzer.

PARKING, LICENSE PLATE AND TA IL LAMPS : System DescriptionINFOID:0000000009463554
PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION
When the lighting switch is in 1st or 2nd position, BCM detects the LIGHTING SWITCH 1st or 2nd POSITION
ON. The BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The IPDM
E/R then activates the tail lamp relay which sends power to the parking and instrument illumination circuits.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 1st or 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the exterior lamps remain illumi nated for a period of time unless the lighting switch posi-
tion is changed. If the lighting switch position is changed, then the exterior lamps are turned off.

XENON HEADLAMP
DescriptionINFOID:0000000009463586
OPERATION
Refer to EXL-9, "HEADLAMP SYSTEM : System Description".
PRECAUTIONS FOR TROUBLE DIAGNOSIS
• Installation or removal of the connecto r must be done with the lighting switch OFF.
• When the lamp is illuminated (when the lighting switch is ON), do not touch the harness, HID control unit,
inside of the lamp, or the lamp metal parts.
• To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle-side
connector.
• If the malfunction can be traced directly to the electrical system, first check for items such as blown fuses
and fusible links, broken wires or loose connectors , pulled-out terminals, and improper connections.
• Do not work with wet hands.
• Using a tester for HID control unit circuit trouble diagnosis is prohibited.
• Disassembling the HID control unit or harnesses (bul b socket harness, ballast harness) is prohibited.
• Immediately after illumination, the light int ensity and color will fluctuate, this is normal.
• When the bulb has reached the end of its lifetime, the br ightness may drop significantly, it may flash repeat-
edly, or the light may turn a reddish color.
Diagnosis ProcedureINFOID:0000000009463587
1.CHECK XENON BULB
Install a known good bulb to the applicable headlamp. Check that the headlamp operates.
Is the inspection result normal?
YES >> Replace the xenon bulb.
NO >> GO TO 2.
2.CHECK HID CONTROL UNIT
Install a known good HID control unit to the appl icable headlamp. Check that the headlamp operates.
Is the inspection result normal?
YES >> Replace HID control unit.
NO >> Inspection End.

STEP DESCRIPTION
STEP 1 Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:
WHAT Vehicle Model, Engine, Transmission/Transaxle and the System (i.e. Radio).
WHEN Date, Time of Day, Weather Conditions, Frequency.
WHERE Road Conditions, Altitude and Traffic Situation.
HOW System Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2 Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Incident Simulation Tests”.
STEP 3 Get the proper diagnosis materials together including:
• Power Supply Routing
• System Operation Descriptions
• Applicable Service Manual Sections
• Check for any Service Bulletins
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.
STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Lay-
outs.
STEP 5 Repair or replace the incident circuit or component.
STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad-
vertently created a new incident during your diagnosis or repair steps.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
• Do not apply excessive shock to the control unit by dropping or hit-ting it.
• Be careful to prevent condensation in the control unit due to rapid
temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
• Be careful not to let oil to get on the control unit connector.
• Avoid cleaning the control unit with volatile oil.
• Do not disassemble the control unit, and do not remove the upper
and lower covers.
• When using a DMM, be careful not to let test probes get close to each other to prevent the power tr ansistor in the control unit from
damaging battery voltage because of short circuiting.
• When checking input and output signals of the control unit, use the
specified check adapter.
How to Check TerminalINFOID:0000000009463013
CONNECTOR AND TERMINAL PIN KIT
• Use the connector and terminal pin kits listed below when replacing connectors or terminals.
• The connector and terminal pin kits contain some of the most commonly used NISSAN/INFINITI connectors
and terminals. For detailed connector and terminal pin r eplacement procedures, refer to the latest NISSAN/
INFINITI CONNECTOR AND TERMINAL PIN SERVICE MANUAL.
