The anti-lock braking system (ABS) uses several sensors, motors, and a computer in conjunction with the normal braking system.
The ABS regulates the brake pressure in order to reduce wheel lock-ups. Reduced wheel lock-ups improve the driver's control of the vehicle during braking.
Improved stability and steering enable greater control of the vehicle in the case of an abrupt stop. The ABS operation is available from 5 km/h (3 mph) to the maximum vehicle speed. A warning light means a problem was detected, and the system needs to be scanned for codes in order find out the area the fault is in. With the light on, ABS operation is not present, but normal braking is.
Check engine light - Also known as the SERVICE ENGINE SOON or SES light. This indicates a malfunction in the engine control and emissions systems of your car. Step by step instructions on how to do a simple scan to check for computer trouble codes. These codes give an indication as to what system is having a problem. View GM trouble code list.

Red brake warning light
This is usually an indicator of low brake fluid. Be sure to check brake fluid in the master cylinder reservoir. If it is low, then the brake system should be checked for leaks or worn brake pads or shoes.
If the brakes fluid in the reservoir gets too low, air will enter the system and cause a low brake pedal, and a poor or no stopping condition.
This light is different from the ABS brake warning. But a problem in the normal braking system can cause the antilock light to come on
