2020 NISSAN ALTIMA check engine

Malfunction
If the BSW system malfunctions, it will turn
off automatically. The system malfunction
warning message with the BSW indicator
(orange) will appear in the vehicle informa-
tion display.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage continues to appear, have the system
checked. It is recommended that you visit a
NISSAN dealer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the radar sensors.
Do not strike or damage the area around
the radar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the radar sensors is damaged due to a
collision.

Steering Assist cancel
Under the following conditions, the Steer-
ing Assist cancels, and the Steering Assist
status indicator and the Steering Assist in-
dicator turn off:∙ When unusual lane markers appear in the traveling lane or when the lane
marker cannot be correctly detected
for some time due to certain conditions
(for example, a snow rut, the reflection
of light on a rainy day, the presence of
several unclear lane markers)
∙ When the windshield wiper operates in the high (HI) speed operation (the Steer-
ing Assist is disabled when the wiper
operates for more than approximately
10 seconds)
Action to take:
Turn the ICC system off using the CANCEL
switch. When the conditions listed above
are no longer present, turn the ICC system
on again.
Steering Assist malfunction
When the system malfunctions, it turns off
automatically. The Steering Assist status
warning illuminates (orange). A chime may
sound depending on the situation. Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off, restart the engine, resume driving,
and set the Intelligent Cruise Control sys-
tem again. If the warning (orange) contin-
ues to illuminate, the Steering Assist is mal-
functioning. Although the vehicle is still
drivable under normal conditions, have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
Steering Assist maintenance
The camera sensor is located above the
inside mirror.
To keep the proper operation of the system
and prevent a system malfunction, be sure
to observe the following:
∙ Always keep the windshield clean.
∙ Do not attach a sticker (including trans- parent material) or install an accessory
near the camera unit.
∙ Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane mark-
ers. ∙ Do not strike or damage the areas
around the camera unit. Do not touch
the camera lens or remove the screw
located on the camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit a
NISSAN dealer.

– An ultrasonic wave source, such asanother vehicle’s sonar, is near the
vehicle.
∙ Once the automatic brake control op- erates, it does not operate again if the
vehicle approaches the same
obstacle.
∙ The automatic brake control can only operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
∙ In the following situations, the RAB system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep hill.
– The vehicle’s posture is changed (e.g., when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turning the steering wheel fully.
– Snow chains are used. – Wheels or tires other than NISSAN
recommended are used.
– The brakes are cold at low ambient temperatures or immediately af ter
driving has started.
– The braking force becomes poor due to wet brakes af ter driving
through a puddle or washing the
vehicle.
∙ Turn the RAB system off in the follow- ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed truck.
– The vehicle is on the chassis dynamometer.
– The vehicle drives on an uneven road surface. – Suspension parts other than those
designated as Genuine NISSAN
parts are used. (If the vehicle
height or the vehicle body inclina-
tion is changed, the system may
not detect an obstacle correctly.)
∙ Excessive noise (e.g., audio system volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Sys-
tem fault” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
