Here's what you need to do:
1. Verify the Repair: Make absolutely sure the brake work that was performed actually addressed the root cause of the ABS light coming on. Common issues that trigger the ABS light include:
* Faulty Wheel Speed Sensor: This is a very common culprit. A sensor that's dirty, damaged, or improperly connected will trigger the light.
* Low Brake Fluid: Insufficient brake fluid can cause problems within the ABS system.
* ABS Module Problems: The ABS control module itself might be faulty, requiring replacement or repair. This is more expensive.
* Wiring Issues: Damaged or corroded wiring related to the ABS system.
2. Have the System Scanned: After the repair, take your Tahoe to a mechanic or auto parts store (like AutoZone, Advance Auto Parts, etc.) that can scan the vehicle's computer system for diagnostic trouble codes (DTCs). The scanner will identify the *specific* problem that triggered the ABS light. This is crucial. Just fixing *something* related to the brakes isn't enough; you must fix the *precise* issue the computer detected.
3. Address the DTCs: The codes from the scan will tell you exactly what needs to be fixed. The mechanic should be able to clear the codes *after* the problem is resolved. The ABS light will typically go out after the codes are cleared and the problem is fixed if the repair was successful. If the light stays on after the repair and code clearing, the problem likely hasn't been fully addressed.
4. Professional Diagnosis (If Needed): If you're not comfortable diagnosing and repairing brake system issues yourself, a qualified mechanic is essential. ABS systems are complex, and attempting to fix them without the proper knowledge and tools could be dangerous.
In short: There's no magic reset button. The ABS light is a diagnostic tool. Fixing the underlying problem is the only way to get it to turn off. A diagnostic scan is your first step.
