DTC C0110 00

- Pump Motor Circuit

Diagnostic Fault Information

Circuit/System 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.

Conditions for Running the DTC

* Ignition is ON.

* Initialization is complete.

Conditions for Setting the DTC

* The EBCM detects a short to ground or an open/high resistance on the B+ circuit.

* The EBCM detects an open/high resistance on the ground circuit.

* The EBCM detects the pump motor runs continuously.

* The EBCM detects the pump motor is binding or stalled.

Action Taken When the DTC Sets

* The EBCM disables the ABS/traction control system (TCS)/vehicle stability enhancement system (VSES) for the duration of the ignition

cycle.

* The ABS indicator illuminates.

* The red Brake indicator illuminates.

* The Stability Control indicator illuminates.

* The driver information center (DIC) displays All Wheel Drive OFF, Service StabiliTrak and Service Traction Control messages.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present and the ECE 13 response is completed by driving the vehicle at speeds greater than 15 km/h

(10 mph) to complete the self test, and the EBCM will turn off the ABS indicator.

* The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.
