C0110 2014 GMC Sierra Code - Pump Motor Circuit

Quick Answer

The pump motor is an integral part of the Brake Pressure Modulator Valve (BPMV), while the pump motor relay is integral to the Electronic Brake Control Module (EBCM). Common causes include Faulty Electronic Brake Control Module (EBCM) with Brake Pressure Modulator Valve (BPMV), Electronic Brake Control Module harness is open or shorted, Electronic Brake Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C0110 2014 GMC Sierra Description

The pump motor is an integral part of the Brake Pressure Modulator Valve (BPMV), while the pump motor relay is integral to the Electronic Brake Control Module (EBCM). The pump motor relay is not engaged during normal system operation. When the Antilock Brake System (ABS) or Traction Control System (TCS) operation is required the EBCM activates the pump motor relay and turns the pump motor ON. The Diagnostic Trouble Code (DTC) will be set when the EBCM detects a low voltage in the pump motor supply circuit when the feedback voltage is less than 4.5 V for greater than 150 ms, and the pump motor is not activated.
