APPLIED VEHICLE: 2013 – 2014 Altima Sedan (L33) equipped with LDW and BSW

SERVICE INFORMATION
This bulletin contains supplemental diagnostic information related to 2013 and 2014 Altima
Sedan equipped with the Lane Departure Warning (LDW) and Blind Spot Warning (BSW)
systems.
Although the Electronic Service Manual (ESM) should be the primary source of information
for inspection, Diagnosis, and repair, the Supplemental Diagnosis information in this
bulletin will assist in these areas.

The information in this bulletin includes:
• What to check / inspect first when a BSW / LDW related warning is shown in the
Vehicle Information Display
• What to check / inspect first when the BSW and/or LDW lights are flashing, and/or
DTCs are stored
• Additional ITS Information that is helpful for system diagnostics.
•

Possible error codes that may display on the navigation screen during “Affordable
ITS Camera” calibration.

Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly
and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume
that it does. See your Nissan dealer to determine if this applies to your vehicle.

Information
Display

Figure 1

•

LDW / BSW lights to the left of the Vehicle Information Display are flashing

Preliminary Checks

1. Resolve DTCs for non ITS (Intelligent Technology Suite) first.
•

Issues with other systems may trip a BSW / LDW related DTC due to improper
communication. Resolve the cause of any DTCs for other systems first. Once the
non ITS DTCs are resolved, check for BSW / LDW related lights / DTCs again.

2. If DTC U1308 is stored; check the following possible causes:
•

Part(s) have been replaced:
¾ RR camera
¾ ITS controller

•

Disconnected / loose connections:
¾ RR camera
¾ ITS controller
¾ ITS switch

•

Wrong part installed (may show error 2 when calibrating):
¾ RR camera is not ITS camera
¾ Dash switch

3. Refer to the Additional ITS Information on the next page for details that may help with
diagnostics.

4. Continue diagnosis / repairs using the ESM.

Additional ITS Information
•

IBA (Intelligent Brake Assist) light may turn ON if the ITS controller is disconnected.

•

ITS system is sensitive to heavy rains and wet surfaces (this is stated in the Owner’s
Manual). Customer comments may state that the system is not working properly or
note that the system shuts off when no objects exist.
¾ Example: The camera unit detects reflected images of vehicles or
roadside objects that are not actually in the detection zone, especially
when the road is wet.
¾ Refer to “BSW driving situations” in the “Starting and driving” section
of the Owner’s Manual.

•

LDW / BSW white icons in dash will blink if the system is temporarily disabled. The
“clean camera” message may also appear in the Vehicle Information Display.
Normally, this is due to low washer fluid level. “Washer Fluid Low” warning will
appear in the Vehicle Information Display.
If LDW / BSW white icons in dash blink and/or the “clean camera” message appears
in the Vehicle Information Display and washer fluid is OK, test the washer pump
related to the camera cleaning system located in the trunk. Other possible causes to
check would be the pump ECU in the trunk and/or washer hoses, making sure fluid
is properly getting to the camera cleaning system.

•

“Initialize Camera Image Calibration” in CONSULT III plus: Do not use this feature
unless instructed by NNA personnel i.e. TECH LINE, etc.

•

When a NAVI system has been replaced, it is possible that ITS concern items may
have been disconnected or triggered. Check for DTCs and if necessary, recalibrate
the ITS system.
