The Vehicle Dynamic Control (VDC) system uses various sensors to monitor driver inputs and vehicle motion. Under certain driving conditions, the VDC System helps to perform the following functions:
● Controls brake pressure to reduce wheel slip on one slipping drive wheel so power is transferred to a non slipping drive wheel on the same axle.
● Controls brake pressure and engine output to reduce drive wheel slip based on vehicle speed (traction control function).
● Controls brake pressure at individual wheels and engine output to help the driver maintain control of the vehicle in the following conditions:
– understeer (vehicle tends to not follow the steered path despite increased steering input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain control of the vehicle, but it cannot prevent loss of vehicle control in all driving situations.
When the VDC system operates, the indicator in the instrument panel flashes so note the
● The road may be slippery or the system may determine some action is required to help
keep the vehicle on the steered path.
● You may feel a pulsation in the brake pedal and hear a noise or vibration from under the
hood. This is normal and indicates that the VDC system is working properly.
● Adjust your speed and driving to the road conditions.
The VDC system is automatically reset to on when the ignition switch is placed in the off
position then back to the on position.
The computer has a built in diagnostic feature that tests the system each time you start the
engine and move the vehicle forward or in reverse at a slow speed. When the self-test occurs, you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an
indication of a malfunction.
● The VDC system is designed to help the driver maintain stability but does not prevent accidents due to abrupt steering operation at high speeds or by careless or dangerous driving techniques.
Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces and always drive carefully
