There are two ways to address the light:
1. Professional Diagnosis and Repair: This is the recommended approach. Take your Silverado to a qualified mechanic or dealership. They'll use a scan tool to read the diagnostic trouble codes (DTCs) stored in the vehicle's computer. This identifies the specific problem causing the light to illuminate. Then, they can repair the underlying issue. Once the problem is fixed and the system confirms it's resolved, the light will usually turn off automatically after a few driving cycles.
2. DIY Diagnosis and Repair (Advanced Users Only): If you're comfortable working on your vehicle, you can purchase an OBD II scanner (available at most auto parts stores). These scanners read the DTCs. However, you'll need to understand what the codes mean and how to fix the related problem. Incorrect repairs could worsen the issue. Many online resources can help decipher codes, but proceed with caution. Once the problem is fixed, the light will usually turn off automatically after a few driving cycles.
Do NOT simply disconnect the battery. While this might temporarily clear the light, the problem will still exist and could cause further damage. The light will likely come back on.
In short: Find out *why* the light is on before trying to make it go off. Fixing the underlying problem is crucial.
