PRECAUTIONS
[ABS]
PRECAUTIONS
[ABS] PFP:00001
Precautions for Battery Service AFS0016E
This vehicle is equipped with the automatic window adjusting function. When a door is opened, the window
automatically lowers slightly to avoid contact between the window and the side roof panel. After the door is
closed, the window will automatically raise slightly.
On vehicles equipped with the automatic window adjusting function, lower both the driver and front passenger
side windows before disconnecting the battery cables. This will prevent interference between the side window
and the roof panel when either door is opened/closed.
CAUTION:
After the battery cables are disconnected, do not open/close the driver and/or front passenger door
with the window in the full up position. The automatic window adjusting function will not work and the
side roof panel may be damaged.
Precautions for Brake System AFS0010P
q Recommended fluid is brake fluid "DOT 3".
q Never reuse drained brake fluid.
q Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.
q Never use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.
q Using a flare nut torque wrench, securely tighten brake tube
flare nuts.
q Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.
q Before working, turn ignition switch OFF.
q When installing brake piping, be sure to check torque.
SBR686C
Precautions for Brake Control AFS0010Q
q During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
q 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.
q Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
q 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.
q 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.
q If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.
q If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
Diagnosis Precaution AFS0010R
CAN SYSTEM
q Do not apply voltage of 7.0V or higher to terminal to be measured.
q Maximum open terminal voltage of tester in use shall be 7.0V or lower.
q Before checking harnesses, turn ignition switch to OFF and disconnect battery negative cable.

ABS Function AFS0010X
q The Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.
q If the electrical system breaks down, then the Fail-Safe function starts, the ABS becomes inoperative,
and the ABS warning lamp turns on.
BRC-6
SYSTEM DESCRIPTION
[ABS]
q Electrical System Diagnosis by CONSULT-II is available.
A
EBD Function AFS0010Y
q Electronic Brake Distributor is a function that detects subtle slippages between the front and rear wheels
during braking, and it improves handling stability by electronically controlling the Brake Fluid Pressure B
which results in reduced rear wheel slippage.
q In case of electrical system break down, the Fail-Safe function is activated, the EBD and ABS becomes
inoperative, and the ABS warning lamp and brake (EBD) warning lamp are turned on.
C
q Electrical System Diagnosis by CONSULT-II is available.
Fail-Safe Function AFS0010Z
ABS, EBD SYSTEM D
In case of electrical problems with the ABS, the ABS warning lamp will turn on. In case of electrical problem
with the EBD, Brake (EBD) warning lamp, ABS warning lamp will turn on. Simultaneously, the ABS become
one of the following conditions of the Fail-Safe function. E
1. For ABS trouble, only the EBD is activated and the condition of the vehicle is the same condition of vehi-
cles without ABS equipment.
2. For EBD trouble, the EBD and ABS become inoperative, and the condition of the vehicle is the same as BRC
the condition of vehicles without ABS, EBD equipment.
NOTE:
In condition 1 described above, an ABS Self Diagnosis sound may be heard. That is a normal condition G
because a self diagnosis for "Key Switch ON" and "the First Starting" are being performed.

CAN COMMUNICATION
[ABS]
CAN COMMUNICATION PFP:23710
System Description AFS00111
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
