I think you are right. We have run into this problem quite a bit. The relay that engages the ABS pump motor is integral with the EBCM and goes belly up. Since it’s part of the EBCM, it’s a rather expensive fix. I think the codes you will see will be C0267-C0268 Ian

Vehicle: 2001 GMC Yukon XL 5.3 L 2WD I’m experiencing problems with the ABS system. ABS light ON. Pump motor is always on, even with ignition off. I pulled the 60A fuse which shut the pump down. Pulling the fuse made the Parking brake light illuminate. Brake hydraulic system still functions normally. No drag or pull. Brakes feel fine and pedal pressure is normal.My guess is the electronic control unit went bad. Your help diagnosing this would be appreciated.
