CAN Communication System DescriptionNIS001WR
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.

SYSTEM DESCRIPTION
Revision: 2006 January2006 M35/M45
from 4 wheel sensors. When ABS actuator and electric unit (control unit) detects a spin at drive wheels
(rear wheels), it compares wheel speed signals from all 4 wheels. At this time, LH and RH rear brake fluid
pressure are controlled, while fuel being cut to engine and throttle valve being closed to reduce engine
torque by the control unit. Further more, throttle position is continuously controlled to ensure the optimum
engine torque at all times.
During TCS operation, it informs driver of system operation by flashing SLIP indicator lamp.
Electrical system diagnosis by CONSULT-II is available.
VDC
Vehicle Dynamics Control system detects driver's steering operation amount and brake pedal travel from
steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel
sensor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving
stability by controlling brake application to 4 wheels and engine output.
During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
Electrical system diagnosis by CONSULT-II is available.
ECD
Receives deceleration degree commandment value signal from ICC sensor integrated unit, and controls brake
fluid pressure with the motor (built-in ABS actuator and electric unit (control unit)).
Operation That Is Not "System Error" NFS000Q7
ABS
When starting engine or just after starting vehicle, brake pedal may vibrate or the motor operating sound
may be heard from engine room. This is a normal states of the operation check.
During ABS operation, brake pedal lightly vibrates and a mechanical sound may be heard. This is normal.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
TCS
Depending on road circumstances, driver may have a sluggish feel. This is normal, because optimum
traction has highest priority under TCS operation.
When vehicle is passing through a road where surface friction varies, downshifting or depressing acceler-
ator pedal fully may activate TCS temporarily.
VDC
During VDC operation, body and brake pedal lightly vibrate and mechanical sounds may be heard. This is
normal.
If vehicle is rotated on turn table, or rolled and rocked on ship, ABS warning lamp, VDC OFF indicator
lamp, and SLIP indicator lamp may turn on. In this case, start engine on normal road again. If ABS warn-
ing lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off after restart, it is normal.
When starting TCS or VDC under rapid acceleration or hard turn, operating sound by brake pedal is gen-
erated. However, this is not malfunction. This is because TCS and VDC are functioning normally.
VDC may not operate normally or ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp
may turn on when driving special roads with extremely steep slant (banks on circuit road and so on.) How-
ever, it is not malfunction when returning to a normal state after restarting the engine. In that case, be sure
to erase the memory of self-diagnosis. Refer to BRC-23, "
ERASE MEMORY" .
Yaw rate /side G sensor malfunction may occur under hard turn like spin turn, rapid acceleration turn, drift
run, etc., when VDC function is OFF (VDC OFF switch is turned on). It is not malfunction if it is possible to
return to a normal position after restarting engine. Then erase the memory of self-diagnosis. Refer to
BRC-23, "
ERASE MEMORY" .
VDC OFF indicator lamp and SLIP indicator lamp may simultaneously turn on when low tire pressure
warning lamp turns on. This is not a VDC system error but results from characteristic change of tires.
Fail-Safe FunctionNFS000Q8
ABS, EBD SYSTEM
In the event there is a malfunction with the electrical system, the ABS warning lamp, VDC OFF indicator lamp,
and SLIP indicator lamp will turn on when it is the ABS that is malfunctioning, and the brake warning lamp,
ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp will turn on when it is the EBD that is
