Failed or seized ABS pump motor.
Faulty pump motor fuse or relay.
Poor or corroded ABS unit ground.
Corroded ABS unit connector.
Internal ABS module fault.

Diagnosis and repair

Check the pump motor fuses and battery voltage.
Inspect the ABS unit ground and connector.
Run a pump activation test with a scan tool.
Replace the ABS unit or module if needed, then bleed the brakes per the manufacturer procedure.
Clear the code and perform a safe brake test.
