LANE DEPARTURE WARNING SYSTEM
Precaution for Lane Depa rture Warning (LDW) systemINFOID:0000000001328492
WARNING:
Lane Departure Warning (LDW) is only a warning d evice to inform the driver of an unintended lane
departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay
alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
LDW system does not operate u nder the following conditions:
- At speeds below approx. 72 km/h (45 MPH).
- If it cannot detect lane markers.
LDW system may not function proper ly under the following conditions:
- On roads where a water puddle, dirt or snow is covering the lane markers.
- On roads where the lane markers are faded or are not painted clearly.
- On roads where the lane markers are painted yellow.
LDW system may not monitor the lane markers in certain road, weather or driving conditions.
- On roads where there are sharp curves.
- Where the traveling lane merges or separates.
- On roads where the discontinued lane marker s are present, such as near tollgates, etc.
- On roads where there are not general lane markers.
- On roads where the lane width is too narrow.
- During bad weather (rain, fog, snow, etc.).
- When strong light (for example, at sunrise or sunse t) is directly shining on the front of the vehicle.
- When entering or exiting a tunnel wher e sudden changes in brightness occur.
- When traveling close to the vehicle in front of you, which causes obstruction of the camera unit
range.
- When the vehicle's traveling direction does not align with the lane marker.
- When rain, snow or dirt adhere to the windshield in front of the camera unit.
Excessive noise interferes with warning system ch ime sound and the chime may not be heard.
CAUTION:
To keep the LDW system operating proper ly, be sure to observe the following:
Always keep the windshield clean. The sensing capability of the camera unit depends on the condi-
tion of the windshield. See “Appearan ce and care” for cleaning instruction.
Never strike or damage the areas around the camera unit.
Never touch the camera lens.
Never attach a sticker (including transparent mate rial) or install an accessory near the camera unit.
Never place reflective materials, such as a white pape r or mirrors on the instrument panel. Reflection
of the sunlight may adversely affect the camera unit's lane marker detection capability.
System DescriptionINFOID:0000000001328493
LDW SYSTEM OPERATION
The Lane Departure Warning (LDW) system warns the driver when the vehicle is traveling close to either the
left or the right of the traveling lane.
The system monitors lane markers of the traveling lane using the LDW camera unit. When the LDW camera
unit detects that the vehicle is traveli ng close to either the left or the right of the traveling lane, the LDW indi-
cator lamp flashes and a chime sounds to alert the driver.
NOTE:
When activating turn signal, LDW system does not give a warning to the lane marker on the turn signal side.
The LDW system can be turned on or off by pushing t he LDW switch. When the system is on, the LDW sys-
tem ON indicator illuminates.
The LDW system has an automatic mode and manual mode.
In the automatic mode
- LDW system automatically turns on, when the i gnition switch is turned to the ON position.
- LDW system ON indicator located on the LDW swit ch illuminates, indicating that the system is on.
- To cancel LDW system, push the LDW switch to turn off LDW system ON indicator.
- To turn on the system, push LDW switch again.
In the manual mode- LDW system is still off when the igniti on switch is turned to the ON position.

PRECAUTIONS
Precaution for Supplemental
Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612915
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution for Procedur e without Cowl Top CoverINFOID:0000000001612935
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
On Board Diagnosis (OBD) System of Engine and A/TINFOID:0000000001325891
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch OFF and di sconnect the negative battery cable before any repair
or inspection work. The op en/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MIL to light up.
Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For descripti on and how to disconnect, refer to PG-68
.
Be sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MIL to li ght up due to the short circuit.
Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to the malfuncti on of the EVAP system or fuel injection system,
etc.
Be sure to erase the unnecessary ma lfunction information (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
for 1st trip freeze frame data and it is updated each time
a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MIL on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.
For example, the EGR malfunction (Priority: 2) was detected and the freeze frame data was stored in the 2nd
trip. After that when the misfire (Priority: 1) is detected in another trip, the freeze frame data will be updated
from the EGR malfunction to the misfire. The 1st trip freeze frame data is updated each time a different mal-
function is detected. There is no priority for 1st trip freeze frame data. However, once freeze frame data is
stored in the ECM memory, 1st trip freeze data is no longer stored (because only one freeze frame data or 1st
trip freeze frame data can be stored in the ECM). If fr eeze frame data is stored in the ECM memory and freeze
frame data with the same priority occurs later, t he first (original) freeze frame data remains unchanged in the
ECM memory.
Both 1st trip freeze frame data and freeze frame dat a (along with the DTCs) are cleared when the ECM mem-
ory is erased. Procedures for clearing the ECM me mory are described in “HOW TO ERASE EMISSION-
RELATED DIAGNOSTIC INFORMATION”.
SYSTEM READINESS TEST (SRT) CODE
System Readiness Test (SRT) code is specified in Service $01 of SAE J1979.
As part of an enhanced emissions test for Inspection & Ma intenance (I/M), certain states require the status of
SRT be used to indicate whether the ECM has completed self-diagnosis of major emission s\
ystems and com-
ponents. Completion must be verified in order for the emissions inspection to proceed.
If a vehicle is rejected for a State emissions inspec tion due to one or more SRT items indicating “INCMP”, use
the information in this Service Manual to set the SRT to “CMPLT”.
In most cases the ECM will automatically complete its self-diagnosis cycle during normal usage, and the SRT
status will indicate “CMPLT” for each application system . Once set as “CMPLT”, the SRT status remains
“CMPLT” until the self-diagnosis memory is erased.
Occasionally, certain portions of the self-diagnostic test may not be completed as a result of the customer's
normal driving pattern; the SRT will indicate “INCMP” for these items.
NOTE:
The SRT will also indicate “INCMP” if the self-diagnosis memory is erased for any reason or if the ECM mem-
ory power supply is interrupted for several hours.
If, during the state emissions inspection, the SRT indica tes “CMPLT” for all test items, the inspector will con-
tinue with the emissions test. However, if the SRT indi cates “INCMP” for one or more of the SRT items the
vehicle is returned to the customer untested.
NOTE:
If MIL is ON during the state emissions inspection, the vehicle is also returned to the customer untested even
though the SRT indicates “CMPLT” for all test items. T herefore, it is important to check SRT (“CMPLT”) and
DTC (No DTCs) before the inspection.
SRT Item
The table below shows required self-diagnostic items to set the SRT to “CMPLT”.

*: If completion of several SRTs is required, perform driving patterns (DTC confirmation procedure), one by one based on the pr
iority for
models with CONSULT-III.
SRT Set Timing
SRT is set as “CMPLT” after self-diagnosis has been performed one or more times. Completion of SRT is
done regardless of whether the result is OK or NG. T he set timing is different between OK and NG results and
is shown in the table below.
OK: Self-diagnosis is carried out and the result is OK.
NG: Self-diagnosis is carried out and the result is NG.
—: Self-diagnosis is not carried out.
When all SRT related self-diagnoses showed OK results in a single cycle (Ignition OFF-ON-OFF), the SRT will
indicate “CMPLT”. → Case 1 above
When all SRT related self-diagnoses showed OK results through several different cycles, the SRT will indicate
“CMPLT” at the time the respective se lf-diagnoses have at least one OK result. → Case 2 above
If one or more SRT related self-diagnoses showed NG re sults in 2 consecutive cycles, the SRT will also indi-
cate “CMPLT”. → Case 3 above
The table above shows that the minimum number of cyc les for setting SRT as “INCMP” is one (1) for each
self-diagnosis (Case 1 & 2) or two (2) for one of self-di agnoses (Case 3). However, in preparation for the state
emissions inspection, it is unnecessary for each self-di agnosis to be executed twice (Case 3) for the following
reasons:
The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result.
The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnosis results.
When, during SRT driving pattern, 1st trip DTC (NG) is detected prior to “CMPLT” of SRT, the self-diagnosis
memory must be erased from ECM after repair.
If the 1st trip DTC is erased, all the SRT will indicate “INCMP”. NOTE:
SRT can be set as “CMPLT” together with the DTC(s) . Therefore, DTC check must always be carried out
prior to the state emission inspection even though the SRT indicates “CMPLT”.
