The ABS light coming on means a sensor, module, or other component in the ABS system has malfunctioned. Here's what you should do:
1. Diagnose the Problem: The first step is to determine *why* the ABS light is on. This requires a proper diagnostic scan using an OBD-II scanner capable of reading ABS codes. Auto parts stores often offer free code reading services. The code will pinpoint the specific problem.
2. Repair the Problem: Once you know the code, you can research the likely cause (e.g., faulty wheel speed sensor, ABS module malfunction, low brake fluid). This usually involves professional repair unless you have significant automotive experience. Replacing a faulty sensor is sometimes feasible for a DIYer, but working on the ABS module is generally best left to a mechanic.
3. Clear the Code (After Repair): After the problem is fixed, the ABS light should go out automatically after a short drive (or sometimes you need to drive a few miles above 30 mph). If it doesn't go out, the scanner can be used to clear the trouble codes. However, if the problem hasn't been addressed, the light will almost certainly come back on.
Important Considerations:
* Safety: A malfunctioning ABS system can significantly reduce braking performance, especially in emergency situations. Do not drive your vehicle with a faulty ABS system if the issue is significant.
* Professional Help: Unless you're comfortable working on car electronics and braking systems, you should take your Impala to a qualified mechanic for diagnosis and repair. Improper repair can lead to further damage or dangerous driving conditions.
In short: Don't try to "reset" the light. Fix the underlying problem. Using a scanner to clear codes is only the final step *after* a successful repair.
