Precautions for Brake ControlNFS0003T

During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.

Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level, and
oil leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

If the following components are replaced with non-genuine components or converted, the VDC OFF indi-
cator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Compo-
nents related to suspension (Shock Absorber, Strut, Spring, Bush, etc.), Tires, wheels (exclude specified
size), components related to brake (Pad, Rotor, Caliper, etc.), Components related to engine (Muffler,
ECM, etc.), Components related to body reinforcement (Roll bar, Tower bar, etc.).

Driving in the condition of breakage or excessive wear of the suspension, tires or components related to
the brakes may cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC
system may not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur if the
brake pedal is used. The noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or the VDC warning lamp may turn on.
However, this is not a problem if normal operation can be resumed after restarting the engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC SW
ON) may cause the yaw rate/side G -sensor system indicate a problem. However this is not a problem if
normal operation can be resumed after restarting the engine.

Adjustment of Steering Angle Sensor Neutral PositionNFS0003W
In case of doing work that applies to the list below, make sure to adjust neutral position of steering angle sen-
sor before running vehicle.
×: Required
–: Not required
1. Stop vehicle with front wheels in straight-ahead position.
2. Turn ignition switch ON and in the following order touch “ABS” “WORK SUPPORT” “ANGLE SENSOR
ADJUSTMENT” in CONSULT-III screen.
3. Touch “START”.
CAUTION:
Do not touch steering wheel while adjusting steering angle sensor.
4. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
5. Turn ignition switch OFF, then turn it ON again.
CAUTION:
Be sure to carry out above operation.
6. Run vehicle with front wheels in straight-ahead position, then stop.
7. Select “DATA MONITOR”, “ECU INPUT SIGNALS”, and “STEERING ANGLE SIGNAL” on CONSULT-III
screen. Then check that “STEERING ANGLE SIGNAL” is within 0±2.5°. If value is more than specifica-
tion, repeat steps 1 to 7.
8. Erase memory of VDC/TCS/ABS control unit and ECM.
9. Turn ignition switch to OFF.
