System Description

INFOID:0000000003247129

• In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected by

the steering angle sensor and pressure sensor, and the vehicle

′

s driving status (amount of under steering/

over steering) is determined by the information from the yaw rate/side/decel 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 or steep slope such as bank. 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 malfunction.

System Description

INFOID:0000000003247133

• The wheel spin of the drive wheels is detected by the ABS actuator and electric unit (control unit) using the

wheel speed signals from the four wheels, so if wheel spin occurs, the drive wheel right and left brake fluid
pressure control and engine fuel cut are conducted while the throttle valve opening is restricted to reduce the
engine torque and decrease the amount of wheel spin. In addition, the throttle opening 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, depressing accelerator pedal fully, sud-

denly downshifts, upshifts, or is driven on a road with a varying surface friction coefficient.

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

• The Anti-Lock Braking System detects wheel revolution while braking, and it improves handling stability dur-

ing sudden braking by electrically preventing 4 wheel lock. Maneuverability is also improved for avoiding
obstacles.

• If the electrical system malfunction, then fail-safe function is activated, ABS becomes inoperative, and ABS

warning lamp turns ON.

• Electrical system diagnosis by CONSULT-III is available.
• During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
• Just after starting the vehicle after the ignition switch ON, brake pedal may vibrate or motor operating noise

may be heard from engine component. This is a normal status of operation check.

• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or

snow-covered (fresh, deep snow) roads.
