• 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 operat ion 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 function and EBD function operate normally. Refer to BRC-39,
"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 pressure) 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.

VDC Function That Prevents Understeer Tendency
• During cornering, brake force (brake fluid pressure) is applied on front wheel and rear wheel on the inner
side of turn. Momentum is generated directing the vehicle toward the inner side of the turn. Understeer is
prevented.
• Applying brakes during cornering on a slippery road, when there may be a tendency to understeer, engine output is controlled as well as brake force (bra ke fluid pressure) of 4 wheels. Understeer tendency
decreases.

• 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 ac tuator 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 suspended for VDC function and TCS func-
tion. However, ABS function and EBD function operate normally.

• By preventing wheel lock through brake force (brake flui d pressure) control that is electronically controlled by
detecting wheel speed during braking, stability during em ergency braking is improved so that obstacles can
be easily bypassed by steering operation.
• During braking, control units calculate wheel speed and pseudo-vehicle speed, and transmit pressure
increase, hold or decrease signals to actuator portion according to wheel slip status.
• The following effects are obtained by preventing wheel lock during braking:
- Vehicle tail slip is prevented during braking when driving straight.
- Understeer and oversteer tendencies are moderated during brak- ing while cornering.
- Obstacles may be easily bypassed by steering operation during
braking.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in ABS function, the control is suspended for VDC function, TCS function
and ABS function. However, EBD function operates normally.

electronically controlled when slight skip on front and rear wheels are detected during braking, stability dur-
ing braking is improved.

• During braking, control unit portion compares slight slip on front
and rear wheels by wheel speed sensor signal, transmits drive sig-
nal to actuator portion when rear wheel slip 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
prevented and slips on front wheel and rear wheel are nearly
equalized. 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-28, "

SELF DIAGNOSTIC RESULT
Operation Procedure
1. Before performing the “Self Diagnostic Result”, st art engine and drive vehicle at 30 km/h (19 MPH) or
more for approximately 1 minute.
How To Erase Self Diagnostic Result
1. After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure t hat the ABS warning lamp, VDC OFF indicator lamp,
SLIP indicator lamp and brake warning lamp turn OFF.
CAUTION:
If memory cannot be erased, perform applicable diagnosis.
NOTE:
• When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp,
SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal, unless
the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 1 minute.
• Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid
level switch operation (when brake fluid is insufficient).
• VDC OFF switch should not stay in ON position.
