SYSTEM
• Brake force control function
at braking hard detects driver′s brake operations with the pressure sensor,
judges a brake booster ′s maximum brake power function by using information from the vacuum sensor, and
enhances more powerful braking force by controlling brakes of four wheels.
• VDC warning lamp blinks while VDC function is in operati on and indicates to the driver that the function is in
operation.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in VDC function, the control is suspended for VDC
function and TCS function. However, ABS functi on and EBD function operate normally. Refer to BRC-41,
"Fail-safe".
INPUT SIGNAL AND OUTPUT SIGNAL
Major signal transmission between each unit via communication lines is shown in the following table.
OPERATION CHARACTERISTICS
VDC Function That Prevents Oversteer Tendency
• During cornering, brake force (brake fluid pressu re) is applied on front wheel and rear wheel on the outer
side of turn. Momentum is generated directing the vehicle toward the outer side of the turn. Oversteer is pre-
vented.
• Changing driving lane on a slippery road, when there may be a tendency to oversteer, engine output is con- trolled as well as brake force (brake fluid pr essure) of 4 wheels. Oversteer tendency decreases.

nication.

SYSTEM
• Wheel spin status of drive wheel is detected by wheel sensor of 4
wheels. Engine output and transmission shift status is controlled
so that slip rate of drive wheels is in appropriate level. When wheel
spin occurs on drive wheel, ABS actuator and electric unit (control
unit) perform brake force control of LH and RH drive wheels (apply
brake force by increasing brake fluid pressure of drive wheel) and
decrease engine torque by engine torque control. Wheel spin
amount decreases. Engine torque is controlled to appropriate
level.
• TCS function can be switched to non-operational status (OFF) by operating VDC OFF switch. In this case, VDC OFF indicator lamp
turns ON.
• SLIP indicator lamp blinks while TCS function is in operation and
indicates to the driver that the function is in operation.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in TCS
function, the control is sus pended for VDC function and TCS func-
tion. However, ABS function and EBD function operate normally.
Refer to BRC-41, "Fail-safe"

• During braking, control unit portion compares slight slip on front and rear wheels by wheel sensor signal, transmits drive signal to
actuator portion when rear wheel sl ip exceeds front wheel slip for
the specified value or more, and controls rear wheel brake force
(brake fluid pressure) so that increase of rear wheel slip is pre-
vented and slips on front wheel and rear wheel are nearly equal-
ized. ABS control is applied when slip on each wheel increases
and wheel speed is the threshold value of ABS control or less.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in EBD function, the control is suspended for VDC function, TCS function,
ABS function and EBD function. Refer to BRC-29, "VDC/TCS/ABS
: Fail-safe".
