SYSTEM DESCRIPTION
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. Refer to LAN-48, "
CAN Sys-
tem Specification Chart" .

Removal and InstallationNFS0003N
COMPONENTS
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts and nuts to specified torques.

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor motor. Remove any foreign
material and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in diagram (2 at shock absorbers and 1 at body panel). When installed, harness must not be
twisted. White line on harness (shaded part) must be visible from front.

System DiagramNFS0003X
VDC FunctionNFS0003Y

In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected
from the steering angle sensor and pressure sensor, and the vehicle's driving status (amount of under-
steering / over-steering) is determined from information from the yaw rate/side G sensor, wheel sensor,
etc., and this information is used to improve vehicle stability by controlling the braking and engine power
to all four wheels.

The SLIP indicator lamp flashes to inform the driver of VDC operation.

During VDC operation, the body and brake pedal lightly vibrate and mechanical noises may be heard.
This is normal.

The ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when the vehicle
is subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while
the engine is running. In this case, restart the engine on a normal road, and if the ABS warning lamp, VDC
OFF indicator lamp, and SLIP indicator lamp turn off, there is no problem.
TCS FunctionNFS0003Z

The wheel spin of the drive wheels is detected by the VDC/TCS/ABS control unit from the wheel speed
signals from the four wheels, so if wheel spin occurs, the rear wheel right and left brake fluid pressure
control and engine fuel cut are conducted while the throttle value is restricted to reduce the engine torque
and decrease the amount of wheel spin. In addition, the degree the throttle is opened is controlled to
achieve the optimum engine torque.

Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the opti-
mum traction has the highest priority under TCS operation.

TCS may be activated any time the vehicle suddenly accelerates, suddenly downshifts, or is driven on a
road with a varying surface friction coefficient.

During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.

ABS FunctionNFS00040

The Anti-Lock Braking 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.

If the electrical system breaks down, then the Fail-Safe function starts, the ABS becomes inoperative,
and the ABS warning lamp turns on.

Electrical System Diagnosis by CONSULT-III is available.
EBD FunctionNFS00041

Electronic Brake Distribution 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
which results in reduced rear wheel slippage.

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 warning lamp are turned on.

Electrical System Diagnosis by CONSULT-III is available.
