What would cause the ABS light to come on an the engine to sound like it is running when turned off on a 2001 Chevy Suburban 2500 LT?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Suburban. The ABS light and the winding noise you're hearing could indicate an issue with the ABS module. In some cases, the ABS pump motor continues to run even when the vehicle is off due to a failed ABS module or relay. If left unchecked, this can drain your battery. It's best to have the ABS system inspected for faults, as it may need a replacement module, relay, or electrical repair. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
