sry if this has already been posted, i skimmed through the manual and it doesnt seem to tell the difference between VDC and TCS, i was just wondering if there was a difference. i have TCS, and VDC comes with the GT package i was jsut wondering what i was missing out on, thanks

VDC Function

In addition to the TCS/ABS function, the driver steering amount and brake operation amount are detected from the steering angle sensor and pressure sensor, and the vehicle's driving status (amount of understeering / over-steering) is determined from information from the yaw rate sensor/side 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. 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 problem.

TCS Function

The wheel spin of the drive wheels is detected by the VDC/TCS/ABS control unit from the wheel speed signals from the four wheels, so if wheel spin occurs, the rear wheel right and left brake fluid pressure
control and engine fuel cut are conducted while the throttle value is restricted to reduce the engine torque and decrease the amount of wheel spin. In addition, the degree the throttle is opened is controlled to
achieve the optimum engine torque.

Depending on road circumstances, the driver may have a sluggish feel. This is normal, because the optimum traction has the highest priority under TCS operation.

TCS may be activated any time the vehicle suddenly accelerates, suddenly downshifts, or is driven on a road with a varying surface friction coefficient.

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

ah, so it helps with oversteering and understeering aswell, thanks for the info i guess it aint that big of a deal :P

In laymans terms, VDC tries to keep you from losing control and spinning out. TCS tries to keep the rear wheels from slipping to maximize traction.

Thank you, Dave . . .

That was an excellent post!

fixed. Besides all the other posts on this topic, it is #6 in the top 100 questions sticky at the top of the forum.

to understand or feel how VDC works.. i suggest try driving in snow (with snow tires of course).

the system is so good its almost impossible to spin yourself out.


on the dry:
i notice when the "SLIP" light turns on, it will still let the rear end come out just a tad bit but will also apply the brake in a way that will help you straighten out from sliding.

Guys, I didn't write or type it. I cut and pasted it from the Factory Service Manual, which happens to be the only place I've ever seen a real explanation of what each system does.

uhh thanks for all the replys x.x i just needed a simple answer heh

A simple answer is difficult since it isn't a simple system. --Spike

So in a nutshell VDC does all that was posted by MC by utilizing and controlling the car with the TCS, EBD, ABS, and direct ignition system.

Its a very slick system but 17 year olds still seem to wrap them around poles
