    All the systems you mention need an input from the Vehicle Speed Sensor (VSS) mounted on the transmission order to work. The one sensor or circuit having failed is likely to have illuminated all the other warning light. A scan tool is need to retrieve codes stored in the computer of your car and then proper diagnostic tests will be carried out to determine what's wrong.
