1. Don't Panic (But Do Be Cautious): Your regular brakes are still functional. However, you've lost the ABS functionality, meaning you won't get the pulsating brake pedal feel during hard braking that helps prevent wheel lockup. Drive more cautiously, especially in slippery conditions.
2. Have it Diagnosed Immediately: The ABS light is triggered by a fault code stored in the car's computer. You need a professional diagnostic scan to determine the exact cause. This can be done at:
* A reputable auto repair shop: They'll have the equipment to read the code(s) and diagnose the problem.
* A Chevy dealership: They'll have the most specific knowledge of your Lumina's ABS system.
* Some auto parts stores: Some larger chains offer free code reading services.
3. Possible Causes (Don't attempt to fix these yourself unless you're experienced): The ABS light can come on for various reasons, including:
* Faulty wheel speed sensor: These sensors monitor wheel rotation and are crucial for ABS function. A dirty or damaged sensor is a common culprit.
* ABS module failure: The ABS module is the "brain" of the system. A malfunctioning module can be expensive to replace.
* Low brake fluid: While unlikely to directly trigger the ABS light, low fluid is a serious issue that needs immediate attention.
* Wiring problems: Damaged or corroded wiring in the ABS system can interrupt signals.
* Faulty ABS pump: This is less common but a possibility.
What NOT to do:
* Don't ignore the light: Driving with a malfunctioning ABS system, especially in adverse conditions, increases your risk of an accident.
* Don't attempt major repairs yourself: Unless you have significant automotive electrical and braking system experience, don't try to fix the ABS system yourself. Improper repairs can worsen the problem or even create safety hazards.
In short, get it diagnosed as soon as possible to determine the exact cause and prevent a potentially dangerous situation from developing. The sooner you address it, the better.
