C0110 on Chevrolet
ABS Pump Motor Circuit Malfunction
C0110 on Chevrolet vehicles indicates abs pump motor circuit malfunction. Au7o has documented this code across 1 Chevrolet model — most commonly on Tahoe. 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. Typical repair costs on Chevrolet range from $100 to $700, depending on the specific model and root cause.
Common Causes of C0110
- •Failed ABS pump motor
- •Faulty pump motor relay
- •Open or shorted pump motor circuit/wiring
- •Corroded or loose ABS module connector
- •Poor ground to the ABS hydraulic unit
- •Low battery voltage or weak charging system
- •Internal failure of the EBCM/ABS module

Chevrolet Tahoe(1 issue)
- EBCM / ABS Module Failure & Corroded Ground (ABS, Traction, StabiliTrak Lights)2000-2006
GMT800 Tahoes commonly light the ABS, Traction Control and (on later trucks) StabiliTrak warnings simultaneously due to the Electronic Brake Control Module (EBCM) or, very often, its corroded frame-mounted ground. The dedicated EBCM ground on the driver-side frame rail is exposed to road salt and corrodes, causing intermittent module communication loss and codes like C0265. Internal EBCM solder-joint failures also occur. Normal service braking still works, but ABS/traction functions drop out.
