I'm not sure, but my wifes 2000 Venture had that problem and it was the speed sensors on the front wheels. If the ECM can't determine wheel speed it can't sense wheel spin (a difference between the two drive wheels) therefore it shuts down the anti-lock brakes which is how it stops spinning, (it uses the brakes to stop the spinning). Maybe this is your problem, hope I helped.

To my knowledge it's the same problem, with different wording. Some cars just have a picture of an engine that lights up. ** added by saxtmich ** In some vehicles there are both service engine soon (ses) and service vehicle soon (svs) lights - like my 1999 Buick Regal for instance. Most of the time you will see the SES light turn on if there is a problem directly related to the engine. The SVS light turns on when you have problems related to other systems such as the traction control system or anti-lock braking system.

If the service light comes on it usually mean there is maintenance needed to be done elsewhere than the engine. Try making sure all your lights work including break lights, turn signals head lights, parking lights, etc.

Pull the ABS fuse located in the engine bay. This disables both traction control and ABS. The lights on the dash will stay illuminated because of the missing fuse.

A person needs to pay attention to their warning lights. If a service engine light is flashing, this means that there is a problem within the engine.

I'm thinking there's a problem with the ABS system somewhere. You'll have to take it to a mechanic with the proper diagnostic hardware to fix this one.

Are you saying that all these lights stay on after you start the car? If so, you need to get the problems fixed that are causing the lights to stay lit. You have these problems. ABS-Anti-Lock Brake System problem. Check Engine- Emissions Controls Problem Trac- Traction control turned off Tire Pressure-Low Tire Pressure Security-?? Read your owners manual carefully.

These are most likely related - when the vehicle detects certain emissions faults it will turn off the vehicle's traction control - not a safety issue. The service light is on due to an emissions control fault - need to have vehicle scanned to find the source of the error.

sounds like a wheel speed sensor has gone out you will need ot replace the wheel bearing.

You mean 'service engine soon'. It lights up as a warning that you should have an auto mechanic look at your engine to see if it needs service. It lights up because a sensor detects that something is not working right.

It is important to pay attention to the service lights in the car. To remove the service light, a person needs to have the engine serviced.

It is important to pay attention to the warning lights in a car. The Service engine light means something is wrong with the engine and once it is taken care of, it will turn off on its own.

The speed sensor is probably defective.

It is important to pay attention to the warning lights on a car. To reset a service engine light on a car, a person must fix the problem causing the light to go off.

you press the hasid lights botten then get out and chek If you are referring to your system fault warning lights, i.e. the service engine soon light or your traction control lights, when you start the car you should see these lights come on. What they are doing is checking the system computers and if it finds everything ok, all the lights go out. If one of the lights stays on, there is a problem. The way to check it is to start the car or start to accessory and see if they light up- If not all of them light, you have a fault. Hopefully this will never happen because most lilkely the instrument panel cluster would have to be replaced to fix it and that is a very large expense.

That is the Service Engine Soon light. You need to have the vehicle checked at your earliest convenience.
