C0110 on 2013-2019 Cadillac XTS — ABS Pump Motor Circuit Malfunction
1 vehicles · 1 makes · $400-$900 repair
Most Reported On
C0110 is an OBD-II diagnostic trouble code meaning “ABS Pump Motor Circuit Malfunction.” This code indicates a problem in the ABS pump motor circuit. The pump motor pressurizes brake fluid so the ABS and stability systems can rapidly modulate the brakes, and the control module detected an electrical fault — such as an open, short, or failure to run when commanded. With the pump unavailable, ABS and stability/traction control are typically disabled, though the conventional hydraulic brakes still function. The warning lights for ABS and traction usually illuminate. This code is most commonly reported on 2013-2019 Cadillac XTS, with repair costs ranging from $400 to $900.
