How to Find Out If a Car Has ABS

Many auto manufacturers have added anti-lock braking systems (ABS) to the host of safety features available in today's newer model vehicles. ABS incorporates a computer controller to analyze the rotation and traction of each wheel. In the event of slippage, the computer takes over the pumping action and fluid system of the brakes to improve stopping ability and vehicle control. The National Institute for Highway Safety reports that about 72 percent of all new cars and 94 percent of new light trucks have ABS. Determining whether a car has ABS will help increase your ability to drive safely in your own vehicle, a rental or a borrowed car. In addition, this knowledge is important when performing repairs or requesting service through dealerships or independent repair shops.

Instructions

1

Check your vehicle owner's manual to determine whether your car or truck has ABS. Some owner's manuals are quite generic and may include information that doesn't apply directly to your vehicle.

2

Turn the ignition on your car without starting the vehicle. Look at the lights displayed on your dashboard. ABS often shows up as an amber colored symbol on the instrument panel.

3

Take your vehicle to a respected mechanic for an inspection. ABS features a separate controller and pump under the vehicle that will be readily visible to a skilled professional. Your mechanic will be following your brake lines to the engine compartment. If your vehicle has ABS, the brake lines will enter a control box located near the engine.

4

Write down your full vehicle identification number. The VIN can be found on a plate affixed to the dashboard near the lower corner of the windshield or on the sticker attached to the driver side door panel. The VIN contains every bit of information about the features available on the vehicle when it was originally produced. Call the appropriate dealership and provide the VIN number to determine if the vehicle has ABS.

5

Consider your own driving experience. If you've felt a pumping or vibrating motion in the brake pedal when driving on slippery surfaces, your ABS may have been engaging to regain traction. Some anti-lock braking systems make a buzzing or grinding noise when engaged.

6

Consult any car rental agents for full information about the safety equipment available on any rented vehicles. Brake application during loss of traction with an ABS vehicle is very different than with non-ABS vehicles. ABS requires firm pressure on the brake pedal to allow the system to work. Brake systems without ABS require the more traditional pumping of the brake pedal to resume control and vehicle traction.
